Hubbard Place Apartments
In 2012, CEG was contracted for an energy and water saving renovation project at the historic Hubbard Place Apartments in the Columbia Heights neighborhood of Washington, D.C. The nine-story mid-rise building is home to 230 residential apartment units, 100% of which qualify for HUD Section 8 rental assistance, as well as three distinct retail/office spaces. The installation was completed on schedule in the fall of 2012.
The goals of this project were to reduce the annual water, electricity and gas consumption of the facility while improving resident satisfaction, lowering maintenance costs and increasing the level of resident security. To achieve these goals, CEG retrofitted the water fixtures in each apartment with lower-flow devices, replaced the primary inefficient hot water boiler, retrofitted service area lights, installed lighting controls in common rooms and retrofitted the exterior lights.
The water measures consisted of replacing each of the 230 units’ toilets and showerheads, as well as installing aerators on each apartment’s kitchen and bathroom sinks. Water bills were immediately reduced by over 35% following the installation of these measures.
Originally, the building utilized two identical boilers, both of which were less than 70% efficient, to handle the domestic hot water heating loads of the building. CEG replaced one of these inefficient boilers with a new 96% efficient model. Due to the reduced load that resulted from the water conservation measures described above, the new boiler is expected to supply all of the building’s hot water needs with one of the old boilers remaining for system redundancy. The overall reduction in gas demand is expected to lower gas bills by approximately 40% annually.
Due to the fact that Hubbard Place is on the National Register of Historic Places, CEG could not change the existing approved lighting fixtures on the exterior building. Instead, CEG carefully selected LED and induction kits that could fit inside the existing fixtures. The result was a light profile that not only saves approximately 53,000 kWh of electricity annually, but also improve light rendering for the security cameras to produce clearer images. Lamp and ballast replacements in the service areas, as well as occupancy control and timer installations in all common rooms, further reduced electricity bills.
In total, the utility conservation measures at Hubbard Place are expected to result in annual savings of over 5 million gallons of water, 15,500 therms of natural gas, and 56,000 kWh of electricity. The expected annual energy savings yield the equivalent environmental impact of planting nearly 3,000 trees or avoiding the consumption of nearly 13,000 gallons of gasoline and the expected annual water savings are enough to fill up 7.5 Olympic sized swimming pools. CEG’s energy and water measures are expected to result in over $80,000 in savings for Hubbard’s utility bills, with a portion of the savings going to Resident Services Programs, which directly support the need’s of the buildings residents.

Hubbard Place Apartments
The building, which was constructed in the late 1920’s and has been placed on the National Register of Historic Places, is a nine story mid-rise with 230 apartments along with ground floor retail and office spaces, located just blocks from the new D.C. USA retail complex, Tivoli Theater, and the Columbia Heights metro line. The renovations and the on-site resident services have transformed this once very distressed property into a vibrant new community which is safe and secure, making the property once again an asset to the neighborhood.
