NWC –Capital Build
1. Energy Efficient Buildings
2. District Thermal using Wastewater Heat Recovery
3. Renewable Energy
4. Community Resiliency
100% renewable electric using a combination of on- and off-site sources
A LOW CARBON, RESILIENT CAMPUS
Prioritizing energy efficiency to achieve LEED Gold or above.
Utilizing wastewater thermal energy to heat and cool campus buildings efficiently.
Ensuring critical facilities have power, heating and cooling, even during extreme events.

METRO WASTEWATER IGA
1. Relocate and bury the Delgany Interceptor
2. Provide access to wastewater thermal energy
3. Mitigate odors from the Delgany via a new biofilter
Metro Board and City Council approved, January 2019
IGA: Intergovernmental Agreement

• Load density
• Available utility corridor
• Mechanical room space
• Development schedule
• Lifecycle cost
• Operations strategy
• Future flexibility
The heat available is
more than twice the
capacity required to
supply the entire campus.
