Vornado will pursue multiple efficiency and electrification projects in their building at One Park Avenue. They will replace two No. 2 fuel oil boilers with air to water heat pumps on the roof, install hot water fan powered boxes, upgrade the building envelope with additional wall insulation, and add window inserts to the building's exterior to reduce the infiltration, heating, and cooling loads on the building. Through increased efficiency of both the heating and cooling systems, a reduction of building load and removal of fossil fuels from the system, One Park Avenue will be able to drastically reduce its carbon emissions.
