D.C. Housing Authority
In 2015, as part of a comprehensive multi-phase project, Altura (in partnership with ThinkBox Group) worked with the District of Columbia Housing Authority (DCHA) to complete a renewable power generation feasibility study to explore renewable energy opportunities throughout DCHA’s portfolio. The project has resulted in the development of multiple viable scenarios, using on site renewable power generation technologies such as fuel cells, combined heat and power, solar thermal and photovolatics, and other advanced power generation technologies. Altura is now leading the Phase 2 implementation phase in partnership with ThinkBox Group.
Phase 2 consists of an $89 million portfolio-wide energy conservation project which covers 24 sites in the DCHA portfolio, encompassing 197 buildings, 4.2 million SF, more than 5,000 units, and $13 million annual utility costs. Altura is serving as the technical lead, completing site audits and developing a comprehensive list of energy conservation measures designed to dramatically improve energy efficiency and occupant comfort at each site. The scope of the project is multi-faceted, and includes energy conservation measures, a microgrid redevelopment project, 3,000 kW of solar PV integration including 1,500 kW provided to DCHA under a Government of the District of Columbia’s Department of Energy and Environment Solar for All grant, and comprehensive MEP equipment upgrades.
The project scope includes boiler retrofits (18 sites), heating hot water system control retrofits (15 sites), lighting retrofit and controls (20 sites), and various other energy, water, envelope, and control measures. Ultimately, the project is expected to net 36% electricity savings (15 million kWh), and 51% natural gas savings (1.9 million therms), and 28% water and sewer savings, representing more than $165 million total savings through 2029.
