Additional Projects
Retro-Commissioning
Elevation at Gateway
Washington, DC
Energesco performed retro-commissioning for a 500,000-square-foot high-rise multifamily building. The HVAC system consists of multi-level exhaust systems in the garage, central boilers, and condenser water loop with cooling towers in the mechanical penthouse. Ventilation was provided by two OAUs located on the roof. Heating and cooling were provided to each zone and apartment through local water source heat pumps. The Energesco team completed functional testing for the winter and summer seasons and provided a list of deficiencies and energy conservation measures to reduce the overall energy consumption of the building.
Energy Assessment
Dock and Maren
Washington, DC
Energesco performed a comprehensive energy assessment for Dock and Maren high-rise residential buildings that were reported to have a higher energy consumption compared to other buildings in the owner’s portfolio. The primary goal was to identify Energy Conservation Measures (ECMs) to facilitate planning for improvements in building performance that would result in reductions in operating expenses and greenhouse gas emissions. The secondary goal was to evaluate building equipment, find operational and maintenance issues, and verify energy allocation between tenant and landlord.
