Columbia Heights Village
CEG implemented a comprehensive utility savings package for Columbia Heights Village Apartments – a 406-unit, 31-building affordable apartment complex located in Washington, D.C. As part of the initiative, CEG installed energy-efficient lighting in the common areas and exterior areas of the building, and upgraded water fixtures in each of the residential units with high-efficiency toilets, showerheads, and faucet aerators. In total, the utility conservation measures at Columbia Heights Village reduced water consumption by approximately 24 million gallons and electricity consumption by 100,000 kWh per year. During the first year of implementation, water savings measures cut consumption at the facility by 60% compared to the previous year.
CEG went beyond the traditional energy conservation measures and implemented creative strategies that further reduced energy consumption. CEG held multiple “Energy Awareness Days” at Columbia Heights Village to inform tenants of the energy and water retrofits that were taking place on the campus. CEG also performed multiple fixture demonstrations in unoccupied units. These engagement programs ensured that building tenants were involved in each step along the way. Furthermore, CEG provided all tenants with training material which detailed how they could reduce utility, energy, and water consumption. This intensive level of tenant engagement resulted in savings beyond the original estimates.
CEG also undertook a renewable energy initiative by installing a rooftop solar photovoltaic (PV) system. This PV system is estimated to produce 25 MWh of electricity per year and meet approximately 5% of the common area’s electrical demand. According to the National Renewable Energy Laboratory, at the time of installation, there were only two solar PV installations larger than this one installed in the District of Columbia.
Estimated Annual Savings: $228,000
- Annual Savings over $225,000
- 31 Buildings & Campus-wide ECMs
- Electricity Savings of 100,000 kWh/year
- Water Savings of 24,000 kGal/year
