Integrated Infrastructure• Optimizing Existing Infrastructure
• Building New Regenerative Systems
Overview• Water-Energy-Air-Materials-Biodiversity are intrinsically
linked components of sustainability
• Success requires
– Innovation – Systems and Technology
– Functionality – Data collection and Long Term
Performance Assessment
– Value Proposition
• Rewards via incentives
• Penalties via compliance enforcement
• Integrated infrastructure systems approach produces the
paradigm shift required to achieve desired moon shot
goals

Linear Segmented Approach
Adds energy at each step
Depletes resources on supply side
Contaminates environment on disposal side

Integrated Systems Reduce and Reuse
Add less energy at each step and extract energy post consumer use
Use less natural resources on production side
Release less contaminants to environment on post consumer side

•Sustainable Sites Initiative
•ASHRAE 189.1
•Developed by ASHRAE, USGBC, IES
•Published January 22, 2010
•First code intended commercial green building standard (not a design guide or rating system)
• ASHRAE 191 – Water Reuse Standards currently being drafted
Water Conservation / Guidelines & Standards
Status Quo - meet regulation
Green –exceed regulation
Sustainable – address future needs
Regenerative – restore function
The quintessential dual flush toilet – What’s in Your Tank?
Logic
• If given the choice would you flush your toilet with bottled water?
• So why is this our current standard?
• Logic will ultimately prevail

The Roman Goddess of the sewers, Cloacina, carried wastes to the river - so began our modern perspective on waste management - dilution is the solution. So begin the tragedy of the water commons (Garrett Hardin,
Science, December 13, 1968 in reference to William Forster Lloyd 1833)

One Bryant Park, New York City Greywater/Rainwater Reuse
• Capturing kinetic energy of greywater and rainwater from 52 story drop
• Gravity pressure zones every 10 stories
• Low energy treatment –filtration/disinfection
• Nonpotable reuse for toilet flushing and cooling

Recent NYC Water and Sewer Rates
• Construct tanks as integral part of foundation walls to economize –concrete represents approximately 35% of costs
• $45/GPD capacity for small system of 25,000 GPD = $1 M
• $21/GPD capacity for medium system of 300,000 GPD = $6.3 M
• $16/GPD capacity for larger system of 500,000 GPD = $8 M
• Includes concrete tanks, start-up and 6 months operations
•Other Costs Factors
•Distribution System
•Stormwater treatment, storage and interconnection
