PCC E6 Net-ZeroPortland, Oregon
Published in May 2009, The E6 Net Zero Project is a technical report GBD co-authored, along with Gerding Edlen Development, GLUMAC and David Evans & Associates, Inc. The team conducted a concise and thorough investigation of the current energy, water and carbon footprint of Portland Community College's Sylvania campus in southwest Portland.
The report outlines a path to achieving a fully NET ZERO campus.
The study looked at several systems to achieve these ambitious goals, including: solar photovoltaic system; waste to energy system, with a fuel cell that produces electricity; closed loop geothermal system; on-site water harvesting and treatment; HVAC controls upgrades; plumbing fixture replacements; envelope improvements; and centralized chilled water.
The report concluded with five different options for the college to pursue. They ranged from simple energy efficiency upgrades all the way to fully NET ZERO:
- Option 1. Building efficiency and water efficiency upgrades
- Option 2. 2 MW SolarRoof Upgrades plus option 1 measures
- Option 3. 1.1 MW Generator plus option 1 measures
- Option 4. Roof upgrades plus option 1, 2, and 3 measures
- Option 5 (NET-ZERO). All measures. Building efficiency measures, Building water efficiency upgrades, Fuel cell, Centralized chilled water, 2 MW Solar PV, Roof upgrades, Closed Loop Geothermal
Funding for construction stems from a $374 million bond measure approved by voters in 2008. Click here to read more about PCC's bond program.
