New York City Council Proposes AC Mandate to Make Buildings Environmentally Friendly

New York City's push to make buildings more environmentally friendly comes with a challenge: maintaining comfortable temperatures for tenants. Under Local Law 97, property owners are required to reduce their buildings' greenhouse gas emissions. A new City Council bill adds another requirement: keeping building temperatures at or below 78 degrees Fahrenheit when outside temperatures reach 82 degrees.

The Environmental and Health Dilemma

Air conditioning, while essential for comfort during hot weather, is not environmentally friendly. However, extreme heat poses significant health risks. According to city statistics, approximately 350 people die each summer due to hot weather, with the vast majority of these deaths (340) classified as "heat-exacerbated," meaning that high temperatures worsen existing health issues. As heat waves become more frequent and intense, reconciling environmental efficiency with tenant comfort becomes increasingly important.

Other Cities' Approaches to Cooling

While some cities have similar regulations, there is a lack of comprehensive statewide policies, even in areas historically known for high temperatures. In Houston, landlords must provide cooling options to maintain temperatures 20 degrees lower than outside or 80 degrees, whichever is warmer. Dallas mandates that owners ensure cooling equipment keeps indoor temperatures at least 15 degrees cooler than outside and no hotter than 85 degrees. Phoenix requires temperatures to be maintained at 82 degrees or lower with air conditioning, or 86 degrees with evaporative coolers. Oregon has legislation preventing landlords from banning air conditioners, and Los Angeles County is considering similar measures. In contrast, a statewide mandate in Florida has not progressed.

Concerns and Challenges for Landlords

Landlord groups in New York express concern about the feasibility of updating buildings to meet the new cooling efficiency standards without incurring significant fines. The New York Times reports that property owners would have four years to comply with the new measure after it is passed. This timeline poses a challenge for many landlords who need to retrofit their buildings with energy-efficient cooling systems.
