In Washington, DC, existing buildings are responsible for 74% of the city’s greenhouse gas emissions. Long-term, sustained reductions of existing buildings’ energy use is the most effective way for the city to combat climate change. Energy target reduction goals were set for each of the different energy conservation scope types. These targets aligned with the amount of capital investment that was being made in each of the scope types.

The plan includes the following:

• Whole building retrofit: comprehensive, impacts all subsystems
• Whole system retrofit: upgrades to entire systems; HVAC, lighting, and/or enclosure
• Component retrofit: upgrades to individual components of a systems; light source, weatherization, boiler, chiller, terminal unit
• Retro commissioning: optimization of sequence of operations + repair, replacement, or additional controls
• Ongoing commissioning: optimization of sequence of operations, identification of items for future capital work
