Chapter 1: Introduction
Abstract
The City of Austin Parks and Recreation Department aims to develop resilience hubs in
Austin, Texas based on the Urban Sustainability Directors Network (USDN) 2018 Resilience
Hub report . The concept of resilience hubs is at the nexus of climate mitigation, 1
adaptation, preparedness, and equity to enhance and improve community sustainability
and resilience by providing clean, distributed, and reliable off-grid backup power for
communities. Recent and projected increases in extreme climate-related disasters and
hazards have highlighted the importance of community climate planning.
Climate change is causing evermore intensified and increasingly frequent extreme weather
events. According to the National Oceanic and Atmospheric Administration , in 2017 the 2
United States suffered $300 billion dollars worth of damages from climate-related events.
And $265 billion was spent to address the damages from sixteen hurricanes alone. These
events are not only costly economically, but also cause incalculable damage socially and
environmentally.
Also in 2017, Hurricane Harvey hit Houston, Texas, located just 165 miles or a three hour
drive from Austin. According to the National Hurricane Center , “over 300,000 structures in 3
that region were flooded, with up to 500,000 cars reported flooded as well. About 336,000
customers lost power during the hurricane. An estimated 40,000 flood victims were
evacuated to or took refuge in shelters across Texas or Louisiana. FEMA reported that
about 30,000 water rescues were conducted during Harvey.” Harvey resulted in $125 billion
dollars in damages lamenting it as the most costly storm in 2017 and second most costly
storm in U.S. history only behind Hurricane Katrina in 2005.
The City of Austin is taking steps to implement resiliency measures in city planning and
development to manage the effects of climate change and protect the city’s most at-risk
and vulnerable communities.

According to Mercy Corps , extreme climate events have more detrimental impacts on 4
vulnerable low-income communities. Around the world, people are experiencing both
subtle climate stressors such as desertification and heat as well as stark climate shocks
such as hurricanes, wildfires, and snowstorms. Poor communities are disinvested and
under-resourced, and as a result are at much higher risk to the effects of climate change.
These communities are also known as environmental justice communities. According to the
Department of Environmental Conservation , environmental justice communities are 5
communities where 50% or more of the population are minorities or live at or below the
federal poverty line . 6
Environmental justice communities are often located in environmentally vulnerable areas
(such as on floodplains or next to polluted areas), have lower-quality construction
materials, are unable to afford regular maintenance for existing infrastructure. These
factors all exacerbate their inability to respond and adapt to climate impacts.
Environmental justice communities lack the adequate resources to escape from, withstand,
and recover from extreme climate disasters, therefore, poor communities are more likely
to become climate refugees. From 2015 to 2016, the number of people affected by natural
disasters doubled from 102 million to 204 million, and that figure is only increasing. Climate
stressors and shocks are forcing people out of their homes and livelihoods. One-third of
the planet’s land is no longer fertile for agriculture, and 1.3 billion people on this
deteriorating agricultural land . 7
Climate change does not discriminate, but people do. We as a society live in a segregated
world that is the culmination of centuries of discrimination by both socioeconomic class
and race. Economic and political tools to segregate communities include red-lining,
gerrymandering, and racially restrictive deed covenants - legally written restrictions in
deeds that excluded classes of people from buying or renting property in particular
neighborhoods. What these actions have yielded are physical patterns of segregated,

oppressed, and disadvantaged communities that are also the most vulnerable to the
effects of climate change.
Resilience hubs offer a proactive planning intervention to address existing and exacerbated
climate justice issues. Resilience Hubs are existing community facilities equipped with
localized renewable energy technology and a battery storage system for energy assurance
during times of extended or widespread grid outages caused by severe climate events such
as hurricanes, wildfires, flooding, and heat waves. Schools, libraries, firehouses, police
stations, community centers, and affordable housing complexes are good building
typologies for a resilience hub retrofit because they are usually distributed throughout
cities and have community recognition.
Resilience hubs also have an important function in the community during non-crisis times
to educate and engage community members on climate preparedness best practices,
sustainable job trainings and workshops, and emergency response protocols. Resilience
hubs are opportunity spaces to involve local residents in citywide and regional climate
planning efforts. Resilient infrastructure in the form of resilience hubs is the foundation
and support of social resilience.
It is essential for cities to take the lead in developing resilient climate infrastructure such as
resilience hubs. My capstone project focuses on two main components: creating a strategic
planning framework for resilience hubs and developing innovative financing mechanisms
to create a network of resilience hubs.
Background
In its simplest definition, resiliency is a system’s ability to recalibrate or bounce back from a
major shock or disruption, and is also known as climate adaptation. Disruptions can include
both naturally and artificially induced events that we will refer to as hazards. Hazards pose
a serious threat to the electrical grid, and can cause extended and widespread outages for
thousands of customers. The people who are most impacted by electrical disruptions are
socioeconomically vulnerable and disadvantaged communities. Strategies to reduce the
vulnerability of the electrical grid are necessary to minimize impacts of climate change
events especially for the high-risk communities.
8
In order to utilize climate planning strategies, it is important to develop renewable sources
of energy and create a more distributed energy system to reduce systemic vulnerabilities.
resilience hubs are the nexus of climate change adaptation and sustainable energy
development. According to Clean Energy Group’s 2015 Resilient Cities Report , “resilient 8
power, sometimes called ‘energy assurance,’ expresses a simple concept: it is the ability to
provide needed power, independent of the grid. Because our electric grids are vulnerable
to storms and other disasters, the ability to generate electricity to power critical facilities
and infrastructure should the grid go down is paramount in emergency planning.”
Austin, Texas is a socioeconomically unique U.S. city. It is the city with Majority-Minority,
where there is no single ethnic or demographic group that makes up the majority of the
City’s population. According to the City of Austin , the City’s Anglo (non-Hispanic white) 9
population dropped below 50% sometime during 2005, and will be projected to stay that
way in the future. Though the city as a whole is racially diverse, issues of equity creates
spatial patterns of division. According to the 2015 Martin Prosperity Institute report,
Segregated City , Austin, Texas is the overall most economically segregated large metro 10
city in the U.S. based on education, income, and occupation. Patterns of economic and
racial segregation are closely correlated and apparent in many cities, and Austin is no
exception. In Austin, communities of color are clustered around the periphery of the city.
Many neighborhoods lack diversity in Austin, which is correlated to the quality of public
resources, utilities, and built infrastructure.
Austin’s patterns of spatial segregation is also linked to physical barriers. Interstate-35 (I-35)
cuts through Austin, running vertically through the city. The highway acts as a boundary
separating the East side of Austin, where there are significantly higher populations of
minorities and immigrants, and lower median household incomes compared to the West
side of I-35.

The City of Austin has more agency over its energy generation than other cities because the
City owns its electric utility, Austin Energy. This allows the City to guide generation planning
11
decisions and the City Council has more decision making power over the direction of
emissions reduction. In August 2014, the Austin City Council adopted a resolution to reduce
carbon dioxide emissions from all City-owned generation resources to zero by 2030 . And 11
in December of 2014, the council passed the 2025 Generation Plan, which is a resolution
that supports renewable energy generation to reach 55% of customer-demand by 2025.
Strategies in this plan includes developing 600 megawatts of utility-scale solar, and
implementing a plan to develop at least 10 megawatts of energy storage and 20 megawatts
of thermal storage.
The Future
Austin, Texas has seen rapid demographics changes in the last few decades starting in the
early 1990s. From 2000 to 2010, Austin saw a 37.3% overall population increase, and from
2010 to 2017, the city experienced another 23.3% population increase . This population 12
growth does not show signs of stopping in the near future. According to the Census Bureau
estimates, Austin will remain one of the country’s top destinations for migrating talent. In
2015, Austin ranked first among the 50 largest U.S. metros based on net migration as a
percent of total population.
Austin’s population and commercial growth is showing no signs of stopping in the near
future. So it is important for the City to plan for the urban changes of densification and
future impacts of climate change. Austin can leverage population trends to utilize human,
social, and built capital to support overall citywide resiliency.

Chapter 2: Resilience Hub 411
Resilience hubs are community facilities equipped with solar photovoltaics (PV) and battery
storage for energy assurance in times of extended or widespread grid outages due to
13
severe climate hazards. Resilience hubs function as emergency shelters for the surrounding
community during times of disaster or extreme climate. Resilience hubs can be new
construction or retrofitted from existing facilities. My past research and capstone project
focuses on retrofitting existing building typologies as resilience hubs to utilize and
strengthen existing city assets and built capital.
Figure 7: What is a resilience hub by Summer Sandoval 2019
Resilient power projects require stakeholder identification of “critical facilities”. For the
development of resilience hubs, a critical facility will be one that is well-utilized and has
cultural and community significance for the surrounding residents. The basic concept for
resilience hubs is focused on energy assurance or resilient power. The electrical grid is
vulnerable to climate events that may cause both widespread and extended outages as
well as short-term brown and black outs, and this is a significant threat because all human
systems rely on power. Short-term outages can be caused by interruptions in energy
generation and demand of electricity. Hospitals, wastewater treatment plants, firehouses,
data centers, police stations, schools, and millions of homes (just to name a few) all rely on
14
the electrical grid and provide invaluable societal functions. Any disruptions to the electrical
grid threatens millions of people and valuable infrastructure.
Resilience hubs are not a one size fits all type of intervention. Resilience hubs are flexible
and scalable in nature, which is one of the most powerful aspects in adapting to climate
change. Along with energy resilience, an effective resilience hub should also be equipped
with other attributes that enhances its functionality. These other building characteristics
can vary by building typology, community, city, or region.
For example, a resilience hub in New York City may have flood-proof ground floor and
green infrastructure to address local issues of storm surge flooding and on-site stormwater
retention and filtration. A hub in NYC would also anticipate hurricanes as the most
prevalent climate hazard that threatens the city, and size the solar array and battery
storage to provide enough resilient power for anticipated outage durations.
In Austin, resilience hubs may include rainwater cisterns for rainwater capture and on-site
filtration and extensive greenroofs to increase solar panel efficiency due to high average 13
annual temperatures . High ambient air temperature can impact the performance of solar 14
panels, so pairing solar arrays with greenroofs allows a building to capitalize on both sets of
co-benefits offered by renewable energy and green infrastructure. “Greenroofs do not
make it in Austin because they get destroyed by the heat,” said Assistant Director of the
Parks and Recreation Department, Liana Kallivoka. Austin sees fifteen hours of solar
irradiance, sunlight, during the summer and eleven hours in the winter. Austin is located
near the equator and receives direct sun exposure. Solar panels alone lose efficiency in
these hot environments. Solar greenroofs increases solar panel efficiency, provides shade
to plants to grow, and expands functionality by including stormwater retention, air
purification through evapotranspiration, and provide habitat for biodiversity.

Figure 8: Regional variability for resilience hub characteristics
Resilience hubs are also resources themselves during non-emergency periods. They act as
engagement opportunities to educate local residents on the risks of climate events,
importance of energy resilience, and best safety practices. These locations may also offer
an array of classes, seminars, workshops, and activities related to sustainability topics.
The potential site should be a facility that is already or likely well-utilized by the
surrounding community. Schools, recreation centers, and other community facilities are
good sites to analyze as you develop site selection criteria. Criteria that you assess may
align with your project goals and the focus areas. Criteria will reflect the community you are
planning to serve and the type of hazards that may be anticipated.
Hub Characteristics
One of the main aspects of a resilience hub is a renewable energy source. The most
common on-site distributed clean energy source is solar PV. Solar panels are becoming
more integrated into the energy profiles of many cities. Solar PV innovation makes the
technology attractive because it is flexible in design to fit various building typologies and
regions. Solar panels can be traditional roof systems, ground-mounted, pavilion or canopy,
16
or integrated into the building envelope. The economy is also supporting solar
development. Since 2009, the cost of solar PV has dropped over 80% and is still falling.
Figure 9, shows the relationship between the falling solar prices and the amount of solar PV
installed.
Figure 9: Falling cost of solar PV and solar PV installations 2009-2017 Source: Solar Energy Industries Association
The complimentary technology to solar is battery storage. A part of the battery storage
system includes a battery-based inverter. This inverter acts as the control between the
building system and the electrical grid. When the grid is working the inverter is monitoring
the building’s demand by moving excess on-site generated solar energy into the grid and
drawing from the grid when the building’s demand is high. The battery-based inverter can
also detect abnormalities and changes in the electrical grid and can disconnect or island
from the grid to become a resilient microgrid . A traditional grid-tied solar PV system only 15
has grid-tied inverter, and when the electrical grid is down then the solar PV system turns

17
off as well. A grid-tied system can only interface with the electrical grid when the grid is
operational and does not have islanding capability to operate on its own. Figure 10 and 11
show the technology system differences between a traditional grid-tied solar system and a
solar and battery storage system.
Figure 10: Traditional grid-tied solar PV system
Figure 11: Solar and battery system with islanding capability
18
When calculating the appropriate capacity for your solar + storage system, it is important to
identify the critical load of the building. Critical load is also referred to as emergency load
and is the energy demand of all equipment to which power is to be maintained under any
circumstance. Critical load will determine what will be powered in a building by the back-up
system even when the electrical grid is down. Consider the use and function of the building
as a shelter. Start with the devices and equipment that absolutely must have power during
an emergency or grid outage and build a list from there. Research the maximum power
draw for each of these devices that you would like to keep running. Power requirements
may be specified directly on the device or available online. Then think about how long the
building will need to power each device in an emergency situation. A standard metric for
critical loads is 20% of the building’s average energy demand. The critical demand will also
help you determine the inverter size and appropriate size estimate for battery storage.
Figure 12: Determining critical load for buildings. Source: U.S. Department of Energy, Solar Market Pathways
The system size of solar power and battery storage is evaluated for the specific building or
building typology. Regional needs are also adaptable for example, Austin may implement
more stormwater capture and filtration features in their resilience hubs, while New York
City may want to flood proof their resilience hubs.
19
Chapter 3: Who, Where, and Why
Resilience hubs is both a climate adaptation and environmental justice intervention. The
effects of climate change such as extreme heat, drought, hurricanes, blizzards, extreme
cold, cloudbursts , wildfires, etc. do not inherently only target populations of poor and 16
disadvantaged communities. Centuries of segregation and discrimination from
governments, financial institutions, education systems, and society have all contributed to
physical landscape that yields close correlation among income, race, and climate
vulnerability.
Environmental justice communities are areas with either 50% or more minority population
and/or 50% or more of the population at or below the Federal Poverty Level. Systematic
discrimination disproportionately puts low-income and communities of color,
environmental justice communities, at high risk of not only climate events but also
becoming climate refugees. Climate refugees are people who are forced from their homes
or livelihoods due to climate impacts, and search for safer places to reside.
Sudden climate shocks such as hurricanes, that cause significant damage to built
infrastructure leaves environmental justice communities homeless and without resources.
For example, after hurricane Maria hit Puerto Rico in 2017, 250,000 people fled from their
damaged homes to seek safety in the U.S. mainland . Hurricane Maria destroyed 80% of 17
the island’s electrical lines. It took six months to restore electrical service to residents, but
that was only in urban areas such as San Juan. In rural places, it took 11 months to restore
electricity to people. The aftermath of hurricane Maria was deemed the largest blackout in
U.S. history and the deadliest natural disaster to hit U.S. soil. The storm directly killed 1,427
people, and indirectly caused the death of over 4,600 people.
Resilience hub planning calls for site selection criteria that may vary from city to city, but
standard metrics to include are average household income and race. It is also important to

20
identify spatial patterns and relationships between income and race because in many
cities, they are closely correlated. Other characteristics to analyze includes access to public
transportation, presence of floodplains, sources of pollution, micro-climates, and exposure
to specific climate hazards.
Resilient climate infrastructure such as resilience hubs are so important because resilient
infrastructure is the foundation of citywide climate resilience as well as social resilience.
Resilience hubs help protect people from losing their lives while also bringing people
together during times of emergency as well as times of non-crisis to educate the
community on the risks of climate change. Resilient infrastructure provides safe and
healthy places for people to live, learn, and grow and supports overall community health . 18
Resilient infrastructure is multi-faceted and offers various co-benefits to the building site
and the surrounding communities. For example, a resilience hub can be used as an
emergency shelter during large climate disasters, as a cooling center during extreme heat
events, and a community resource center for programming and workshops during
non-crisis periods.

21
What are the risks?
Austin, Texas has a relatively safe geographic location. It is not on the coast, which serves
for additional protection from storm surges, sea level rise, and hurricanes. It is also just far
enough from tornado alley. But this does not mean that Austin is not affected by hazards
and climate-related disasters. Austin is vulnerable to flooding, wildfires, heatwaves, and
aridification just to name a few climate disasters and stressors. With this in mind, it is
important to consider the vulnerability of neighboring cities because accommodating
evacuees and climate refugees is also be a function of a resilience hub.
One of the most important aspects of developing a resilience hub is identifying the types
and scale of disasters that are expected to occur. This can significantly differ among
regional climates and geographic characteristics; plans can even vary by city depending on
both natural and artificial attributes that may impact vulnerability and risk of climate
events. For example , wildfires are more prevalent in the Pacific Northwest of the U.S., but 19
human influence over forest management may have increased the risk of wildfires in this
region. Florida has over a thousand miles of coastline, which make it extremely vulnerable
to damage from hurricanes and tropical storms, so investment in non-climate resilient
infrastructure may result in putting even more people at risk of displacement from these
extreme climate events.
According to the City Department of Homeland Security and Emergency Management,
Austin’s highest risk to hazard is flooding. Austin and Central Texas is also referred to as
flash flood alley ; the area is the most prone to flooding in the U.S. Austin is constantly 20
battling with water. Extreme heat and demand in the summer causes drinking water
shortages and heavy downpours in spring and fall cause flooding issues. Onion Creek
located in the southeast side of Austin has a history of terrible flooding. The creek has
caused costly damage during its 1981, 2013, and 2015 floods. The Austin Department of
Watershed Protection estimates that it will cost up to $4 billion dollars to complete all the

necessary buyouts and measures to protect against flood damage because there are 2,200
structures . As of today, the City has com
Chapter 4: Benefits of Solar + Storage
During non-crisis times, resilience hub’s solar and battery storage systems offer the
building on-site electricity savings. According to the U.S. Green Building Council , solar 21
energy offers a wide variety of cost benefits and transcends on-site savings with positive
economic, social, and environmental externalities. The solar photovoltaic system reduces
energy costs in Austin, Texas in three ways: first by reducing overall energy consumption
from the electrical grid by generating power on-site, second by generating income through
Austin Energy’s Value of Solar program that pays customers per kilowatt hour of solar 22
power generated, and third by Austin Energy’s Performance-Based solar incentive that is 23
also based on kilowatt hour of solar power produced on-site. Electrical savings are the
direct benefits from on-site solar. Solar energy also offers diverse co-benefits to the
building site and surround community.
Battery storage is an integral aspect of resilient power. Battery storage technology supports
renewable energy integration in citywide energy profiles by allowing renewables to provide
baseload energy. One of the major shortfalls of renewable energy sources is their
intermittent nature. Solar panels can only generate power when the sun there is sun, just
as wind turbines can only generate energy when the wind is blowing, but people use
energy throughout the day at varying levels of demand. On their own, renewables cannot
meet the constant power demand.
Battery storage can also provide cost savings by reducing peak demand. Many utilities base
electrical bills for customers off of both consumption and demand. Consumption is the
total amount of energy used by a building or unit in a monthly billing period. Consumption
is measured in kilowatt hours and is based on actual usage. The second part of an electrical

23
bill are demand charges. These are charges based on the single highest demand of power
sustained for a fifteen minute period. Demand is how much energy a building or unit is
using at any point in time and is measured in kilowatts.
Battery storage can provide cost savings through peak shaving because battery technology
is controlled and can be deployed when needed during emergency as well as times of high
demand. Figure 14 illustrates how battery storage can reduce the high peak demand from
a building and reduce demand charges.
Figure 14: How battery storage can manage electricity demand over a 24-hour period
Investing in resilience means that the money spent on protecting existing assets will save
more money in damages in the future. According to Federal Emergency Management
Agency (FEMA), U.S. Economic Development Administration (EDA) and U.S. Department of
Housing and Urban Development (HUD) and found mitigation funding can save the nation
$6 in future disaster costs, for every $1 spent on hazard mitigation . This figure takes into 24
account the cost and time of recovery and future inflation. It is more cost effective to
protect people and infrastructure today than it is to wait for the next climate hazard, and
pay for the damages.
24 “National Institute of Building Sciences Issues New Report on the Value of Mitigation - National Institute of Building Sciences,” accessed May 12, 2019, https://www.nibs.org/news/381874/National-Institute-of-Building-Sciences-Issues-New-Report-on-the-Value-of-Mitigation.htm.
24
According to the National Renewable Energy Laboratory, the average cost savings from
avoided outages is $100 per kilowatt hour . Lawrence Berkeley National Laboratory and 25
Nexant, Inc. developed the Interruption Cost Estimate calculator with funding from the U.S.
Department of Energy’s Office of Electricity Delivery and Energy Reliability. This online
calculator is an electric reliability planning tool that allows the user to see the cost of
outages by region and utility service provider.
Solar and battery storage have co-benefits beyond on-site energy savings. Burning fossil
fuels for energy creates harmful air pollutants that include greenhouse gases that
contribute to climate change effects. According to the U.S. Environmental Protection
Agency (EPA), the social cost of carbon is $42 per ton . But a 2015 Stanford University 26
study suggests the true social cost of carbon is actually $220 per ton . This is an important 27
co-benefit from solar and battery storage systems because environmental justice
communities usually endure more negative impacts from concentrated air pollution.
Environmental justice communities also have lower quality or less ecological benefits from
natural systems and processes such as greenspaces.

Florida SunSmart Emergency-Shelters
Resilience hubs are a relatively new concept, but implementation has sprouted around the
world. One notable resilience hub case study is the Florida SunSmart Emergency-Shelter
program. In 2012, the program was created in response to Florida’s long history of damage
caused by hurricanes along the Atlantic coast. According to the National Oceanic and
Atmospheric Administration (NOAA) , forty percent of all major hurricanes hit Florida. With 28

1,350 miles of coastline, Florida is highly vulnerable to the destruction of extreme weather
events such as hurricanes and other tropical storms that impact the
Figure 15: Hurricanes that impact U.S. States from 1851-2017
The Florida Sunsmart program was implemented by the partnership of the University of
Central Florida’s Florida Solar Energy Center in collaboration with Florida’s Office of Energy.
The program worked with the local utility to retrofit a total of one hundred and fifteen
public schools with small 10 kilowatt solar array and 40 kilowatt batteries that can provide
resilient power that includes lights and electrical outlets as the critical loads.
The program was funded by the American Recovery and Reinvestment Act, which
designated funding to invest in infrastructure, education, and renewable energy. The solar
arrays for the schools were installed on the ground to provide an outdoor classroom space
for students to learn about renewable energy. “Educating Floridians and utilizing energy
efficient technologies will strengthen our economy by increasing Florida’s energy
independence and reducing greenhouse gas emissions.” said Govern Charlie Crist.
26
To date, 350 teachers are trained through renewable energy workshops and over 50,000
students have been introduced to solar PV through STEM (science, technology, engineering,
and math) curriculum that was also developed by the SunSmart program.
The schools are designed to be Enhanced Hurricane Protection Areas , which are open to 29
the public during times of disaster and can accommodate 100-500 people varying by
school size. The state was able to negotiate a volume discount by using a single installer for
all the schools. The schools did not have to pay any upfront costs for the systems and
receive $1,500-$1,600 in electric savings annually . 30

Marcus Garvey Apartments
In response to hurricane Sandy, New York City experienced shock that forced the issue of
climate resiliency to become a priority in city planning and projects across city agencies,
community advocacy organizations, and concerned private property owners. The Marcus
Garvey Apartments pilot program is an important case study because it is the first

affordable residential microgrid in New York City. Marcus Garvey apartments is a thirty-two
building affordable housing complex located in Brownsville, Brooklyn.
This project was the first microgrid project deployed through Con Edison’s
Brooklyn-Queens Neighborhood program, which aims to reduce peak demand in specific
New York City neighborhoods. Con Edison’s Brownsville substation serves the
Brooklyn-Queens area, but is overtaxed especially in the summer months when peak
demand is very high. Urban densification development is putting excess stress on the
electrical grid. In order to address the new demand needs in the area, Con Edison would
need to built another substation costing $1.2 billion dollars . 31
A new substation that relies on fossil fuels is a traditional solution to ongoing issue. Fossil
fuels are not reliable for resilient power. Back-up fuel oil generators often do not have
enough supply oil on-site and generators are at higher risk of explosions and fires than
renewable technology. The solar and battery storage upgrade cost a total of $1.3 million
dollars. Twenty-two of the buildings in the complexes were upgraded with solar panels
totaling 400 kilowatts of solar energy, 300 kilowatt/1,200 kilowatt hours battery, and a 400
kilowatt fuel cell system.
The project was financed with about $300,000 from solar incentives and a $1 million dollar
loan from a non-profit organization, New York Energy Efficiency Cooperation. The loan is a
10-year loan and is repaid with the monthly energy savings from the solar and battery
storage system.

Chapter 7: Planning Recommendations
Strategic Planning Framework
1. Resilience network
The overall goal of developing resilience hubs is to protect people. Resilience hubs are a
key strategy in climate planning that emphasizes equitable investment in infrastructure.
The result of a successful resilience hub program will protect all environmental justice
census tracts with a designated resilience hub. Priority areas for resilience hub
development will be focused on serving all people living below the federal poverty line. A
resilience hub network will utilize a diverse portfolio of building typologies throughout the
city. Community engagement and education is essential in siting resilience hubs because
each community utilizes different community assets in their neighborhoods. For example, it
would not be effective to retrofit a library as a resilience hub if not many people in the
community use or see it as a resource, and if the library is located in an isolated part of a
community.
It is important to analyze the distance that different building typologies serve. Elementary
schools may have a smaller reach in the community only serving within a one mile radius
compared to a high school that is larger and serves multiple census tracts. All of these
29
aspects are important parts in creating a resilience hub network that serves environmental
justice and vulnerable communities.
Figure 18: Recommended Austin resilience hub network vision by Summer Sandoval 2019
2. Emergency Response Plan
An important aspect of emergency preparedness is communication. My next
recommendation is to create accessible, customized, and on-line emergency response
plans. People need to know what to do for different climate hazards and in different
situations. Resilience hubs will not be effective if no one knows how to utilize them during
times of emergency and disaster. An easy online application that people can access on their
phones, computers, and offline is necessary to communicate emergency best practices and
protocol.
Another part of the recommendation includes resilience zoning, which let people know
where the closest resilience hub is and which hubs serve the area they live in. Resilience
zoning can also communicate resilience hub function to the community. In cases of
extreme heat, not every household owns or can afford air conditioning units. Heat waves
30
are especially dangerous for young children, pregnant women, elderly people, and other
people who are impacted with health concerns.
During times of extreme heat, people can receive a notification that tells them which
resilience hubs are functioning as cooling centers. Solar, battery storage, and building
critical loads can be altered by season to reflect community needs. In the summer, when
heat waves are the most prevalent climate hazard critical loads can be increased to include
air conditioning during the hottest times of the day for at-risk populations to stay cool.
An effective emergency response protocol will clearly address the following:
1. What people should do during a specific climate hazard
2. Where people should go during a specific climate hazard
3. How people should act during a specific climate hazard
4. When people should evacuate or return to their homes
5. Who are most at-risk for a specific climate hazard
This information must be available in various online and offline forms and mediums as well
as regularly updated with the newest information. Climate hazard information also must be
available in many languages in order to ensure environmental justice communities are
aware of emergency response best practices.
Chapter 8: Funding Recommendations
Innovative Financing Mechanisms
Today, many climate resilient and sustainable infrastructure projects are funded through
short-term grants and recovery funding. This is an issue because cities cannot wait for
disasters to build better infrastructure and it is more cost efficient to invest in resilient
infrastructure before the next climate disaster. The vision and goal for developing
innovative financing mechanisms for resilience hubs is to create a long-term, sustainable,
and self-sustaining resilience fund to cover all capital costs of resilience hub project costs. A
resilience fund would ensure that resilience hubs are developed in a timely manner to to
protect vulnerable communities.
31
1. Clean Business Standard
One way to create a large pool of sustainability investors is to engage with the private
industry to develop resiliency design and implementation. The first financing
recommendation is write resiliency into the building code by creating a Clean Business
Standard. A Clean Business Standard outlines specific sustainability requirements that all
new and existing businesses must comply with. These standards can also be flexible and
adaptable to a city’s specific needs. For example, businesses in southwestern U.S. states
may be required to develop more water efficiency and greywater recycling strategies. In
many cities that struggle with combined sewer overflows from stormwater runoff may
create stricter criteria for businesses to comply with on-site stormwater management
standards. A citywide Clean Business Standard can be adapted by existing green building
rating systems such as Leadership in Energy and Environmental Design (LEED) , which is 32
the most widely used voluntary rating system in the world.
The Clean Business Standard can dictate roofing type for all new roof replacements to
require a certain percentage of a new roof be a sustainable option such as a type of
greeroof or renewable energy development. For example, all new roof replacements must
dedicate at least 50% of available rooftop area to a sustainable rooftop option.
Not all businesses have suitable rooftops for greenroofs or solar PV arrays, so it is
important to offer various options to comply with a Clean Business Standard. If businesses
do not have suitable roofs for sustainable rooftop options then they can create these
sustainable initiatives off-site through a resilience fund. A business with an unsuitable
rooftop can still undergo an appraisal on the what it would cost to cover 50% of the rooftop
with either a standard mid-cost greenroof or commercial solar panels, and pay that amount
into the resilience fund. The resilience fund would then become a long-term fund that can be
utilized for City-led resiliency projects such as resilience hubs. The business would also pay
small annual maintenance fees into the fund as they would usually dedicate for their own
maintenance. The resilience hub project would be credited to the businesses that funded
them as compliance with the clean business standard.
32 “LEED v4.1 O+M Beta Guide | U.S. Green Building Council,” accessed May 13, 2019, http://www.usgbc.org/resources/leed-v41-om-beta-guide.
32
Required:
All existing and new businesses would have to comply with specific green building
requirements outlined in a citywide Clean Business Standard. The standard would require
on-site building resiliency measures and adaptations that addressed holistic climate
resiliency. If certain buildings cannot fully comply with the Clean Business Standard with
on-site measures due to economic efficiency, then the business can choose the alternative
to pay a resilience fee into the a citywide resilience fund. The resilience fund is used to
develop resilience hubs and other resilient building interventions on public buildings. This
requirement would ensure that both public and private buildings receive investment for
resilient infrastructure.
Incentivized:
If businesses go beyond the Clean Business Standard and develop more on-site resiliency
measures then business developers can receive a resilient building bonus, which is similar to
density bonus from inclusionary housing incentives . This incentive will encourage 33
businesses and developers to invest more on-site resilient building measures that will
support overall city resiliency and reduce cost of damages from climate hazards. The
resilient building bonus will allow businesses and developers to build beyond existing
zoning or regulations. Resilient building bonuses can also be allocated to developers that
create resilience hubs on private property. Businesses can choose to create resilience hub
functionality on the ground floor or specific section of their business to receive the resilient
building bonus.
2. ”Sustainability Investors”
The concept of sustainability investors is similar to any other kind of investor. This
recommendation ensures that businesses are both required to invest in citywide resiliency
to a certain capacity as well as incentivize the private sector to invest in resilience projects
not only because they offer valuable co-benefits but because they are economically viable
on their own.
33 “Incentives,” Inclusionary Housing (blog), accessed May 13, 2019, http://inclusionaryhousing.org/designing-a-policy/land-dedication-incentives/.
33
Required:
All businesses are required to comply to the Clean Business Standard, and if they cannot
comply with on-site building measures, then they are required to pay a resilience fee into
the resilience fund. Not all buildings or sites can have the capacity to develop required
resilience building code. If a resilience measure does not meet economic criteria i.e. there is
too much shade and not enough solar irradiance for solar panels, then the business will
pay the project equivalence of developing on-site solar power to the resilience fund. The
fund will cover capital costs of resilient infrastructure throughout the city.
Incentivized:
Many businesses do not know the economics of investing in resilient infrastructure.
Resilient infrastructure is accompanied by a plethora of co-benefits that are enjoyed not
only by the building site, but the surrounding community too. Many solar and battery
storage projects have quick paybacks and positive return on investments, but there is a lack
of communication and collaboration between the public and private sector. Creating a city
resilience bond program can be a way for the city government to partner with local 34
businesses.
If businesses can invest in resilience bonds to fund resilient infrastructure projects, then
they can earn a return on their investments and the city will have the upfront capital
funding to fund resilience hubs. There may be a education curve to get businesses to invest
in these bonds, so cities can incentivize the first business investors with permit waivers and
Clean Business Standard credits to encourage businesses to participate.
3. Property Tax Advance Model
Like many cities, Austin, Texas has relatively high property taxes. Texas, has the sixth
highest property taxes in the U.S. in 2019 . High and rising property taxes and cost of 35

34
homes is a major concern for many native Austinites. Another innovative financing
mechanism for resilience hubs is a property tax advance model for business owners.
Required:
The required aspect of the Property Tax Advance Model would simply require the status
quo of businesses to pay their property taxes on time without any type of discount.
Incentivized:
For small discounts on property taxes, businesses can have the option of paying their
property taxes in advance in different increments such as 5-year, 10-year, 15-year, and
20-year bundle payments. The larger the upfront payment the higher the discount. For
example, if a business had a surplus in revenue for the last few years and wanted to invest
in their business, they could pay their property taxes for the next 3 years and receive a
6-8% discount on the amount paid. This scenario creates a win-win situation for the
businesses and the City. This model allows the businesses to plan long-term and utilize
current surplus for future savings and it frees us money that the City would have received
anyway for more capital projects such as resilience hubs. A pre-agreed upon percentage of
the advance tax payment can then be used to develop resilience hub retrofits because the
effects of climate change are time-sensitive and investing in resilience today will save lives
and money in the future.

Chapter 9: Next Steps
Resilience Hub Elementary School Pilot Program: Cost-Benefit Analysis
Austin Independent School District elementary school pilot program is a proposed network
of resilience hubs retrofitting 22 public elementary schools in Austin, Texas . This 36
cost-benefit pilot program is modeled after the Florida SunSmart Emergency Shelter
program. Forty percent of all hurricanes impact the state of Florida every year. As a
response of climate change and the regular damages from hurricanes, Florida Office of
Energy and University of Central Florida partnered to implement a resilience hub program
to retrofit 115 public schools with 10 kilowatts of solar power and 40 kilowatt hours of
battery storage. These schools also had Enhanced Hurricane Protection Areas (EHPAs),
which offered emergency shelter space to the public and had the capacity to provide up to
8 hours of resilient power from the solar and storage system during times when the
electrical grid was down.
Methodology:
Identify “Priority Areas”: The first step in siting a resilience hub is to determine the
community it will serve. Median household income and race are main characteristics that
define environmental justice communities. In order to address equity issues and climate
change, a resilience hub pilot program will be analyzed for potential costs and benefits on
the east side of Interstate-35 in Austin, Texas. I-35 acts as a physical boundary that cuts
through Austin and divides many affluent neighborhoods on the west side from the
low-income communities on the east side. The communities on the east side also have a
high percentage of minorities. The percentage of “Economically Disadvantaged” students in
each school was also evaluated. “Economically Disadvantaged” is defined if a student
qualifies for the National School Lunch Program for free lunch, which requires a family’s
income to be within 185% of Federal Poverty levels . 37

Figure 20: 2019 U.S. Federal Poverty Guidelines
Examine a building typology: Resilience hub retrofits are recommended for existing
buildings because hubs should have an important community function during
non-emergency times such as education, public engagement, critical service, or housing.
This is an essential aspect of a resilience hub, so there can be community recognition of the
building as a community resource center. Buildings with large flat roofs, available land, and
scalable typologies are good candidates for resilience hubs. For this analysis, I am
examining the cost-benefit of a resilience hub program on 22 public elementary schools 38
in Austin’s environmental justice communities on the east side.

38
Create technology recommendations: Solar and battery storage capacity depends on the
available on-site space as well as the building’s energy profile . For the 22 elementary 39
schools, the solar systems that are appropriate for the site and function ranges from
100-200 kilowatts and the battery storage is kept at of constant of 50 kilowatts/300 kilowatt
hours system size to provide up to 24 hours of resilient power to the building. The critical
for each building is based on 20% of average energy demand. Since the battery capacity
was kept constant for this analysis, the inverter size can vary based on building specific
needs and energy loads to tailor the resilient energy system.
Evaluate costs and benefits: Technology costs for solar panels and battery storage were
analyzed for each elementary school. Costs included materials cost for both solar panel
and battery storage, as well as a 30% project cost for installation and labor. Commercial
solar panels cost approximately $2,000 per kilowatt. Battery storage costs $1,000 per
kilowatt and $500 per kilowatt hour. Benefits for solar and battery storage are
multi-faceted and diverse. On-site benefits include Austin Energy’s “value of solar” credit of
$0.067 per kWh of solar power generated, a performance-based incentive of $0.060 per 40
kWh generated for a medium-sized commercial building, and annual electricity savings 41
from utilizing the generated on-site solar power in the building.

Figure 24: Austin Energy Performance-Based Incentive for on-site solar power generation.
40
Battery storage for resilient power is growing immensely in the U.S. Battery storage is not a
renewable energy source, but is an effective complement to renewable energy technologies
such as solar photovoltaic. Battery storage allows solar power to provide baseload energy
because renewables are intermittent in power generation and does not always correlate
with user demand. Direct benefits of battery storage include monthly demand cost savings
and cost savings from avoided outages which is valued at $100 per kilowatt hour.
The cost of outages were calculated based on the critical loads of schools multiplied by
24-hours of anticipated annual outages due to extreme climate events that will impact the
grid. On-site battery storage can continuously provide resilient off-grid power to the
building for up to 24-hour periods. Potentially, battery storage will provide more economic
value than from just one outage event. After evaluating the direct cost savings from both
on-site solar and battery storage, project economics prove positive and outweigh upfront
capital costs even before analyzing the value of positive externalities or co-benefits.
Figure 25: Elementary school resilience hub pilot project overview
5. Analyze indirect co-benefits: Solar power and battery storage also offer co-benefits or
positive externalities to the building site as well as the surrounding community. Resilience
hubs reduce greenhouse gas emissions from fossil fuel power sources, which have
positive environmental and health impacts. Reduced greenhouse gases such as carbon
dioxide, methane, particulate matter 2.5, and secondary air pollutants such as ozone and
nitrogen oxides that can all cause or exacerbate respiratory illnesses. According to a 2015
41
Stanford study , the true social cost of carbon (equivalence) emissions is $220 per ton 42
instead of the Environmental Protection Agency’s estimate of $42 per ton . The proposed 43
solar arrays would curb 4,000 tons of annual carbon emissions, which is worth an
additional $880,000 in annual co-benefits.
A large-scale resilience hub network in any city would also create a new market demand for
solar and battery storage installers, engineers, and maintenance jobs. Job opportunities will
result in long-term economic benefits by attracting people to the city. Investing in climate
planning such as resilience hubs can attract people in two ways: the first reason is the
safety and adaptability of the city to the effects of climate change, and the second reason is
the economic opportunities that are a result of a successful resilience hub network.
Next Steps
The recommended next steps to implement the elementary school pilot program:
Create an official public partnership with all necessary city agencies that may include Austin
Independent School District (AISD), Department of Parks and Recreation, Austin Energy,
Office of Sustainability, and local community advocacy organizations and residents.
Evaluate climate patterns and future projects to estimate resilient power duration needs
during a widespread electrical grid outage. Identify micro-climate hazards and risks for
neighborhoods, to know what type of disaster to plan for.
Conduct an elementary school building assessment to verify technology system size
recommendations. Determine the status of roofs and building quality to accommodate
solar and battery storage retrofit changes.
Identify financing mechanisms and opportunities among all partners including grants,
bonds, capital and operating budgets, and loans. Evaluate upfront cost needs and
long-term savings cash flow.

There is no “silver bullet” for climate change or resiliency. One thing that is without a doubt
is that a single entity or stakeholder cannot solve all the climate planning problems in a
city. It is also not the sole responsibility of government, businesses, or individuals to work
on citywide climate resilience. It is essential that local governments take a lead on resiliency
measures and engage the private business sector and environmental justice communities.
Climate change impacts are anthropogenic, and were caused and now exacerbated by
systemic issues of poor planning, short-sighted ventures, and the lack of understanding of
holistic systems. As humans, we all play a role in creating negative impacts on planet Earth,
now it is our turn to stand up and stand together to protect one another and lay the
foundation for a more successful future. The vision for our planet is an understanding,
consideration, and respect of the relationship among all environmental, social, and
economic systems. Resilience hubs are just the tip of the iceberg, but they are the
foundation of a climate resilient city.
