Profiles in Energy Efficiency

Throughout the region, schools, local governments, businesses, and residents are realizing considerable financial benefits by integrating energy efficiency into their operations and decision making. DVRPC's series of case studies profile cost-effective and replicable energy-efficiency projects in the Greater Philadelphia region.

These profiles not only highlight the projects in large, commercial buildings, but also include work done by homeowners, and by government municipalities in schools, libraries, and for street lights and traffic signals. In the DVRPC region, emissions from stationary commercial and industrial buildings account for 34.7% of total emissions, while residences account for 25.4% of total emissions.

Resources

There are a wide-range of sources of information on best practices, sources of funding, and technical assistance available for improving energy performance in buildings and outdoor lighting in the Greater Philadelphia Region:

EnergyWorks: The EnergyWorks program, funded by a grant from the US Department of Energy, connects home and business owners with available rebates, tax credits and very low-interest loans. Energy Works is a program of the Metropolitan Caucus comprising the five counties of southeastern Pennsylvania (Bucks, Chester, Delaware, Philadelphia, and Montgomery).

PECO Smart Ideas: PECO's Smart Ideas program is devoted to helping PECO residential and business customers save energy. Their website provides a do-it-yourself Smart Home E-Audit, resources for how to realize energy and cost savings, and information on PECO Smart Ideas rebates and cash incentives.

PGW EnergySense: PGW's EnergySense programs offer a range of energy efficiency rebates and grants to help residential and business customers save energy and save money, from single equipment rebates up to comprehensive building audits and efficiency project grants. More information on PGW's EnergySense programs, including rebate applications, can be found at www.PGWEnergySense.com.

ENERGY STAR Portfolio Manager: Portfolio Manager is a free, secure, online tool for benchmarking building energy performance. Portfolio Manager allows you to evaluate energy use across a portfolio of buildings, assess energy management goals over time, and identify strategic opportunities for savings. Buildings that perform particularly well when compared to their peers may be eligible to receive the ENERGY STAR certification. Portfolio Manager generates an energy use intensity (energy demand per square foot) for each building benchmarked. Portfolio Manager also normalizes for weather and several other important building and operational characteristics, assuring comparisons are made on a level playing field.
