DC requires new buildings over 50,000 square feet to meet the Green Building Act, encouraging vegetated roofs, cool pavement, and tree canopy expansion to combat heat islands documented by DOEE in vulnerable wards.
The Green Building Act of 2006 (DC Law 16-234) and Sustainable DC 2.0 set a target of 40% citywide tree canopy and 6 million square feet of green roofs by 2032. DOEE's RiverSmart Rooftops program offers up to $15 per square foot rebate for vegetated roofs that retain stormwater and reduce surface temperatures. The Climate Ready DC adaptation plan identifies Wards 5, 7, and 8 as heat-vulnerable. The 2024 Heat Emergency Plan triggers cooling-center activation when forecasts hit 95F, coordinated by HSEMA and DOEE.
Most measures are incentive-based. Failure to meet the Green Building Act on covered projects can delay certificate of occupancy and forfeit a posted performance bond up to $3 per square foot.
