Community Energy Challenge • Benchmarking • Reducing Energy Use • Acknowledgements Overview
New England Town • 25,000 people $1M/yr on muni energy • Energy Cost tend to be second to personnel Maine Vermont NH Mass. CT RI
Saves Money Cuts Pollution Reduces Strain on Energy Supplies Why is energy efficient so important?
Challenges communities to save money and reduce air pollution. • Targets the municipal buildings, schools, and wastewater treatment plants. EPA Community Energy Challenge The third year program had reached 146 communities in NE, representing over 30% of NE population.
Benchmark any building • Certain Buildings get a score 1-100 • 75 + • < 75 EPA Portfolio Manager
Familiarize • Assist • Train • Interpret • Refer • Inform renewables Intern Role
Community Energy Challenge Process The Process Step 1. Take the Pledge. ~Community sends in their commitment letter to EPA-NE
Community Energy Challenge Process The Process Step 2 : Initial Meeting, May 27, 2009
Community Energy Challenge Process The Process Step 3 Gather data…
Municipal Buildings Gross Floor Area, zip code Address Year the building was built Number of Personal Computers Number of occupants regularly using the building Weekly operating hours How many months per year the building is in use Electric and Natural Gas/Oil bills on a monthly basis for a 12 month period Data needed for Benchmarking
Community Energy Challenge Process The Process Step 4 Enter Data in Portfolio Manager …
Easy to use with free online training and simple data requirements. • Create login name and password • Intern or town contact will input gathered EUI • data to Portfolio Manager • Receive rating from a rating system EPA Portfolio Manager
