The city's Resource Conservation Manager (RCM) program is reducing energy, water use and solid waste generation in city operations, thus cutting costs, consumption of natural resources and greenhouse gas emissions. The RCM program is funded in part through a three-year grant from Puget Sound Energy.
From April 2008 to March 2009 (the baseline), Bellevue buildings targeted by the program used approximately 13 million kilowatt hours of electricity and 346,000 gas therms, costing about $1.32 million.
Through the RCM program, the city cut energy costs by $392,000 or 16 percent from April 2009 to April 2012 (adjusted for outside temperature variations and excluding savings from capital projects rebated otherwise by PSE).
Total energy savings as of April 2012:
- 2,890 metric tons of carbon dioxide (equivalent to 555 passenger cars per year, calculated using EPA’s eGrid marginal emission factors for NWPP)
- 3,346,000 kilowatt hours
- 141,000 therms
Energy conservation projects the city has implemented thus far include:
- Certification of City Hall as an ENERGY STAR building in 2008 and 2010;
- Lighting efficiency and control upgrades;
- Demand-based ventilation strategies for building automation systems;
- Building commissioning;
- Scheduling mechanical equipment to better match occupancy;
- Adjusting hot water temperatures to 120 degrees F;
- Installing variable frequency drives on pumps and motors;
- Reducing unnecessary plug loads;
- Replacing old boilers with highly efficient ones;
- Installing low-flow water fixtures such as showerheads and aerators;
- Fixing failed equipment and sensors; and
- Educating employees about energy efficiency.
