How the laws fit together
Every covered building uses energy for the same few jobs. Each Local Law looks at a different part of that picture.
Heating
Boiler, steam or hot-water pipes that heat the building.
Cooling and ventilation
Rooftop equipment, fans and ducts that cool and move air.
Lighting
Fixtures on every floor. LL88 requires lighting that meets the NYC Energy Conservation Code.
Plug loads and tenant spaces
Equipment plugged in by tenants. LL88 requires sub-meters for covered tenant spaces over 5,000 sq ft.
Domestic hot water
Tanks and heaters that supply hot water to the building.
LL84 benchmarking: the whole building
Total energy and water use from the utility meters, reported every year in ENERGY STAR Portfolio Manager. The result sets the LL95 energy grade.
LL97 emissions limits: the whole building
The same energy use is converted to carbon emissions and compared with the building's limit. Emissions over the limit are penalized.
LL87 audits: base building systems
An energy audit and retro-commissioning of items 1, 2, 3 and 5, filed once every ten years.
