2009 Master Plan Update:Executive Summary

In 2009, the college of Biological sciences set out to revisit the 2007 Master Plan for Itasca

Biological station and laboratories. this revision reflects an emerging vision for a long-term

sustainable emphasis at the station and responds to current funding restrictions. Key to

this effort is addressing the ability of the station to support basic research, education and

outreach objectives while addressing a crumbling infrastructure.

this Master Plan Update articulates a vision for the station that remains flexible,

capitalizes upon existing building and campus infrastructure, and respects the historic and

environmental character of the station. It demonstrates a long-term path toward a net-

zero energy, self-sustaining campus community, and incorporates strategies to minimize

operational costs. It suggests an integration of program elements to increase vitality, enhance

flexibility, and reduce construction and operational costs. Finally, it describes a Phase one

campus center in terms of design, performance metrics, and project cost.

a summary of the project components and phasing is as follows:

Phase 1 Project: New Campus Center $5,272,500

a new 10,800 sq ft building incorporating classrooms/laboratories, computer room/library,

auditorium and workstations. a classroom renovation in the existing lakeside lab.

Phase 2 Project: $3,140,000

two additional classrooms/laboratories, replacement of 48 beds in summer student housing

to serve for year-round use, and 3 new faculty cabins.

Phase 1 and Phase 2 are essential components to replacing unsafe and inadequate facilities.

these phases address the basic needs of a daily capacity of 150 students and faculty in

the summer and 75 in the winter. Project budgets are intended to reflect advanced energy

efficiency provisions beyond B3 requirements and include renewable energy photovoltaic

panels associated with each phase. Budgets are stated in 2007 dollars and include related

site and campus improvements.

Phases 1 and 2, upon completion, address the programmatic needs of the station for the

next 10 to 15 years. In addition, these phases provide a catalyst for moving the station

toward energy self-sufficiency. Demolition of unsafe and inadequate buildings, operational

management of summer-only and year-round facilities, renovation of existing year-round

buildings to improve energy efficiency (including future renovation/replacement of the dining

hall), and renewable energy components for the station campus as a whole are strategies

that, pursued over time, can fulfill the vision for rejuvenation and sustainability at the Itasca

station.

Building Upon The 2007 Master Plan

this 2009 Master Plan Update builds on many principles established in the 2007 Master Plan

for the University of Minnesota Itasca Biological station and laboratories.

the 2007 Master Plan includes documentation of existing infrastructure, defines

programmatic components for the station, and references the May 2006 Facility condition

assessment report that identifies existing buildings and their conditions. It also establishes

a plan to limit automobile use at the core of the station, suggests sensitivity to building scale

and character in the planning and design of new buildings, and recognizes the spirit of a low-

impact plan within the contextual umbrella of Itasca state Park.

the overall impression from the 2007 Master Plan was a “camp-like” environment with

repeated emphasis on small, single use buildings as a response to scale and a notion of

continuity with the historic roots of the station. With approximately 60 current stand-alone

buildings, the full vision for the completed 2007 Master Plan remains a village of individual

buildings, comprised of three phases that replace buildings and add new program elements

in the range of $25M total project costs.


2009 Initiatives

the college of Biological sciences and the Itasca Biological station and laboratories plan to

address the following areas of interest:

Maintaining and Enhancing Programs

this Master Plan Update prioritizes programmatic requirements for research, education and

outreach that serve the basic needs of the station. summer programs require capacity for

120 students, 30 faculty and 5 staff. Winter programs require capacity for 60 students, 15

faculty and 5 staff.

A Sustainable Community

Framing the station as a sustainable community is a vision consistent with the station’s

environmental focus and its research, education, and outreach mission. this is a tremendous

opportunity to demonstrate environmental awareness and stewardship by the University of

Minnesota at Itasca state Park. a strong emphasis on sustainability, with impacts on long-

term planning, building design, and on-going operational costs, is desired.

A Year-round Facility

the station’s evolution to a year-round facility suggests the need for greater energy efficiency

in a winter climate. Moving to multi-purpose buildings, rather than the “summer camp”

model with buildings dedicated to a single function, will save energy and improve operational

efficiency.

Phasing and Continuous Use

the pragmatic issue of building new facilities while keeping the station in continuous

operation is an important feature of project phasing. current programs at the station need to

remain active. Buildings scheduled for replacement or renovation must remain operational

during construction. new sites should be examined that do not impede existing programs.

In addition, the master plan should carefully integrate the reuse of existing buildings with

continued life into the plan.

Operational Costs

the Itasca Biological station and laboratories, the premier inland field station in the region,

must find ways to maintain facilities on an on-going basis with an adequate operating

budget. Quality of infrastructure, including the cost of maintenance and operation, is a key

factor in Field station Productivity. the analysis of operating costs were not part of the 2007

Master Plan process and should be examined in greater detail with an eye toward driving

down energy and other operational costs at the station.

IntroDUctIon

The Itasca Biological Station provides innovative research and educational programs in a unique and experiential hands-on environment. The Station is hampered by a deteriorating infrastructure in need of rejuvenation.


Overall Land Use and Site Concept

the Master Plan Update envisions the Itasca Biological station and laboratories as a

“clearing in the woods” on the shore of lake Itasca. Visitors pass through the forested areas

to a long sunlit meadow creating a strong arrival experience.

the central Meadow is defined by two larger spaces open to the sky. It creates a sense of

balance when arriving at the station. the north Meadow is the existing recreational field and

includes student cabins and dining facilities. the south Meadow is the historical pasture at

the station. It is selectively cleared of new-growth deciduous trees and creates a new space

for study and potential outdoor classroom activities that is flanked by classrooms, academic

functions, and faculty housing. these two open meadows support the zoning of the station

into areas of quiet study and other more robust activities.

the famous Brower Map of 1892 charted the presence of this long open space on the site of

the Itasca Biological station when the headwaters of the Mississippi were being explored

and mapped. as the station evolved, these open spaces were used as recreational areas

and an old cow pasture at the site of the south Meadow. the 1892 Map also recognizes the

presence of a floating bog (adjacent to Floating Bog Bay) at the southern edge of the property

and east of Bear Paw Point.

the central Meadow is defined by roadways along its eastern edge that lead to two parking

areas at the northern and southern ends of the site and by pedestrian pathways on the

western edge. this pattern of circulation reinforces the desire to keep vehicles out of the

center of the station while providing necessary access for students, faculty, and visitors to

the station. the southern access road generally follows the alignment of the existing service

road and provides access to the new student services building and the boat docks at the

Itasca shoreline. It also provides an opportunity for the station to integrate the presence of

the floating bog as a natural educational feature of the site.

In addition to creating a logical zoning of station into activities and educational areas, the

central Meadow complements the existing cabins along the lakefront. It provides a context

for new buildings away from the lakeshore to orient toward these open spaces and take

advantage of the sun, an important resource in addressing the sustainability goals of the

station. It also provides sites for new construction that can be implemented independent

of the demolition of decrepit or condemned structures and requires no removal of existing

structures that remain in good condition and reinforce the scale of the station.

The chart documents the Proposed Plan for buildings at the Station and their square footages. New construction, demolition, summer usage, and energy upgrades to year-round buildings are indicated.

The Plan addresses the student, faculty, and staff lodging requirements and the Teaching Classroom and other educational needs to meet the program needs of the Station for the next 15-20 years.


the Itasca Biological station and laboratories is a unique setting

within Itasca state Park near the headwaters of the Mississippi river.

the station is a living laboratory that uses its niche to expand the

understanding of our environment and our world.

the notion of a self-sustaining community at the station provides

an exciting framework for learning and discovery. It offers an

opportunity for students, staff and faculty to understand their

relationship to their environment in new and thought provoking

ways. this experience can be woven into curricula centered on a self-

sustainable environment.

the Master Plan Update includes a conceptual framework to work

toward a net-zero energy or near-zero energy station. Planning and

performance metrics will help guide the station toward this goal.

this long-term strategy incorporates super-insulation, passive energy

strategies, natural ventilation, and renewable energy solutions in

new building infrastructure. renovations on existing buildings will

adopt strategies that improve energy performance while maintaining

the cultural integrity of the station.

a net-zero energy environment in northern Minnesota at a year-

round facility requires adoption of passive strategies and building

orientation to minimize the need for renewable energy generation

associated with buildings and the site. accordingly, the Master Plan

Update sites new buildings with orientation and access to the sun.

the Master Plan Update reuses existing buildings when possible

to meet programmatic or cultural objectives. new construction

is minimized through sharing of uses and careful consolidation

of program spaces. sheltered outdoor spaces are used and

natural ventilation and thermal transfer are employed in lieu of

air-conditioning whenever possible reducing energy consumption.

Monitoring energy performance will be an essential operating

strategy for the station.

achieving a net-zero energy community includes:

1. Identifying the natural resources available on the site

2. Developing an aggressive energy use reduction plan

3. Prioritizing renewable energy strategies

4. Verifying design intent

Trees and biomass. considerations include:

· Wood from fallen timber or other local sources as firewood or

wood pellets for biomass conversion to on-site fuel for heating

· nursery or replanting programs to create carbon-neutrality

· existing woodstock for buildings and/or furniture

· continue utilizing existing wells to meet water needs

· Understanding how this water can be recycled and/or filtered

· geothermal (geo-lake) heat exchangers to reduce the cost of

heating and cooling

Wind. considerations include:

· Using westerly and southerly breezes from the lake

· Using small scale wind power solutions

Sun. considerations include:

· active photovoltaics and hot water heating for building projects

· Passive solar heating

· Daylight harvesting to reduce lighting loads

the planning and design of new structures at the station will add

substantial value and can be included with minimal impact on initial

construction costs.

strategies include the use of:

· Minimized building areas through consolidation, shared use,

and programming of outdoor or naturally ventilated spaces when

possible

· strategic building orientation

· Vegetation for natural shading

· geothermal or geo-lake heat exchangers

· solar hot water

· natural ventilation and greatly reduced air conditioning

· radiant heating/cooling via floor slabs

· limited laboratory ventilation to hoods, otherwise treat as

classroom spaces

· Heat exchangers

· super-insulation, earth sheltering, green roofs

· low water use fixtures

· Day lighting

· Passive solar heating

· on-site or local wood products

· Minimize finish materials

Identifying the Natural Resources Available on the Site

Developing an Aggressive Energy use Reduction Plan



Building design can include use of local wood resources. cabins

along the lake can use natural ventilation, shade the hot summer

western sun, and control exposure to cold winter winds. For

buildings in the woods but away from the lake, building orientation is

important and passive natural ventilation can be used. For buildings

in open meadows, building orientation and passive and active solar

strategies can be easily implemented.

the Master Plan Update calls for super-insulated buildings for both

summer comfort and winter energy efficiency. It also includes fully

programmable outdoor spaces and porches to minimize construction

that needs to be heated, cooled, or humidified. the plan utilizes the

existing pine canopy for natural shading and cooling in the summer

and as windbreaks in the winter.

Preliminary design analysis suggests that solar photovoltaic panels,

solar hot water, small scale wind power, and potentially biomass

energy from local wood resources are the most reasonable strategies

to address active generation of energy on the site without disruption

to the state Park environment. these components provide a way for

the station to move fully toward a net-zero energy goal.

Design goals and strategies are essential components of a net-zero

approach. Performance monitoring is essential to verify results.

operational strategies, including zoning controls, monitoring, and

other operating procedures can have a significant impact on energy

use. In addition, these features can be an integrated and exciting

component of the educational program at the station.

other sustainable components of the station

Food production is mentioned in the master plan, allowing the

station to move beyond net-zero energy to include self-sustenance.

the plan includes future gardens and greenhouses. With nearby wild

rice beds and local gardens, the station can create a community-

based program that is self-sustaining and can extend beyond the

station.

students and local residents may have an interest in various

demolition, construction, prefabrication, or data collection efforts.

these resources can be mobilized to reduce costs and encourage

collaboration.

energy usage is an important component of the operational costs of the station. this

Master Plan Update analyzed energy usage, billed for electricity and propane, based on

energy metering data from 2008. While the type of data available does not allow detailed

correlations, it suggests a series of strategies that can be pursued to reduce energy

consumption and point the station toward a zero energy sustainable future.

the analysis establishes, for the various existing station buildings, a “baseline” energy Use

Intensity in kbtu/sf/year, as would be expected for similar facilities assuming the current

combination of summer-only and year-round use. this baseline is similar to the energy

metering data available for 2008.

the proposed new construction (Phases 1 and 2) adds building area to meet the basic

programmatic needs of the station, creating a new baseline for station energy use. Demand

is reduced from this new baseline by applying the following energy conservation strategies:

1. aggressive energy efficient design for new construction (Phase 1 and 2 buildings).

2. Decommissioning and/or demolition of sub-standard existing buildings, as identified in

the 2007 Facilities assessment.

3. Designation and use of buildings with low energy efficiency potential to summer-only

use, based on the proposed station profile for summer and year-round use.

4. energy efficiency upgrades to existing buildings designated for year-round use. these

upgrades, envisioned to occur over a 10-15 year period, are modeled as a 30% reduction

in energy use, consistent with B3 standards.

these energy conservation strategies, modeled campus-wide, result in a reduced station

energy usage that can be offset with on-site renewable energy production. the remaining

energy demand establishes the target for a renewable campus-wide energy strategy, possibly

including solar pv, small wind, and/or a wood biomass central generation plant.

The path to zero-energy is imagined as a 10-15 year process. The new construction anticipated for Phase One and Phase Two Buildings catalyzes a series of energy conservation and renewable energy production strategies at the Itasca Biological Station Campus.


tHe PHase one caMPUs center


the Phase 1 campus center combines program elements from what

were previously three individual buildings in the 2007 Master Plan

into a single building. through sharing of program and support

space, the size of the building has been reduced to 10,800 gross

square feet and is envisioned as both an arrival center for visitors

and an active social center for academic programs at the station.

responding to the historical scale of the station campus, the design

concept breaks the program into two wings that are linked with an

entry and arrival space. this central space functions as breakout

space for seminars and classroom activities and is a gateway to the

station for students, faculty, and visitors.

the building is sited at the southern end of the central meadow,

taking advantage of solar exposure and southerly breezes to create

an environmentally responsive building envelope. Passive and active

energy strategies are incorporated in the design concept, featuring

three primary elements:

earth or sod roofs over the two wings of the building minimize

northern exposures and incorporating earth as insulation to improve

the building’s energy performance. these roofs are wood structures

that incline like “lean-to” forms toward the southern sun and protect

the southern outdoor spaces from winter winds.

southern exposures of the building wings combine active

photovoltaic solar panels with openings for daylighting, view,

ventilation, and passive solar gain.

the entrance lobby and campus gathering space is conceived as

a ventilation tower, pulling air from the wings of the building to

enhance the natural ventilation characteristics of the building. It

is the intention that the campus center can function as a naturally

ventilated building during the summer, with consideration of

mechanical air-conditioning limited to spaces that may require

humidity control.

An Energy Pro-Forma for the Phase One Campus Center

recent examples of low-energy or zero-energy buildings at the scale of the proposed new

construction suggest that it is possible to reduce energy costs through high performance

building design up to 75% of current building code standards, with the opportunity to pursue

renewable energy strategies for the remaining 25%. For new construction at the station, the

following process is utilized to create a sustainable approach for the buildings:

· establish energy use baseline for comparable use projects

· reduce/minimize built area

· Define minimal energy use goal (30% below baseline per UM)

· target aggressive conservation/use strategies (60-75% below baseline)

· Pursue active strategies to achieve a net zero or near net zero strategy

· Verify and monitor design intent

as a case-in-point, the proposed Phase 1 campus center would reduce baseline energy

demand compared to the stand-alone buildings proposed in the 2007 Master Plan by

combining functions and sharing use in a common building, resulting in reduced area for new

construction. advanced design strategies focused on energy conservation would decrease

energy use well past current Minnesota sustainable Building guidelines (B3) requirements.

adding a significant amount of photovoltaic generation integrated with the building design

would leave a relatively minor portion of energy to be generated as part of the campus-wide

energy strategy.

Phase Two Project Costs



to meet the basic program needs of the Itasca Biological station and laboratories and to

fulfill the vision for an energy efficient and sustainable future at the station, the following are

a summary of recommendations:

Construct new Phase One and Phase Two buildings and their associated site improvements

to meet the basic needs of the Station to serve its planned programs and to enhance the

function, interaction, and image of the Station. Include sustainable design elements,

advanced energy conservation strategies, and renewable energy components to achieve a net

zero-energy1 or near zero-energy facility.

Demolish or de-commission substandard buildings no longer required due to the new

construction of Phase One and Two. consider recycling, reuse of components, embodied

energy conversion, and local labor support as part of the demolition process.

Implement a plan to designate existing buildings, not previously constructed to year-round

standards, as summer or seasonal use only buildings to reduce campus-wide energy use.

this strategy is made possible due to the new construction of Phase one and two as year-

round facilities and recognizes the greater programmatic need for space in the summer,

according to the planned programs for the station.

Implement a plan to accomplish energy upgrades to existing buildings scheduled for year-

round use. this plan can meet the requirements of HeaPr funds and minimally can improve

the efficiency of these existing structures to Minnesota B3 standards. of particular concern

are the eventual energy improvements to the Dining Hall, a large energy user on the campus.

this facility should be either upgraded or reconstructed within a 10-15 year time frame.

energy upgrades to existing buildings should follow a similar time frame to achieve campus

sustainability objectives.

Investigate “central” renewable energy strategies for the Station as a whole to address zero-

energy objectives and broader sustainability goals. consider additional solar photovoltaic

panels, geothermal systems, small-scale wind power, and biomass energy production at a

scale that matches the station’s remaining campus energy use.

Incorporate energy management and monitoring systems in new construction and campus-

wide to improve control of building energy use. consider user interfaces to raise awareness

and improve occupant control of the management and use of energy to provide equipment

and comfort needs. Develop a plan to monitor and evaluate energy use.2

In conjunction with educational programs at the Station, investigate broader self-sufficiency

and sustainability programs for the Station. this may include on-site gardens and/or

greenhouses for fruits and vegetables, partnerships with local wild rice, fish, and meat

suppliers, and wastewater, water use, and water quality partnerships with Itasca state Park.

sUMMary recoMMenDatIons

1 For purposes of this study, “zero-energy” is defined as incorporating conservation measures and employing renewable energy components, principally on-site, sufficient to meet the net energy use of the station. this definition does not include broader measures of self-sustenance sometimes used to define sustainability, such as food production, transportation costs, or embodied energy of infrastructure.

2 this Master Plan Update makes planning assumptions regarding energy use based on various data sources and is envisioned as a planning tool. actual energy consumption and overall building performance is influenced by climate variations, design, construction quality, operational measures, and occupant patterns of use. on-going monitoring of energy use is an important component in achieving building performance.
