process, the Tishman Speyer team asked the energy services group at Trane to conduct a financial
analysis of the complex and identify
Through assessment of Rockefeller’s power consumption and utilities billing, Trane designed a
solution to improve the financial operation of Rockefeller Center by taking advantage of previously
unrealized energy and cost saving opportunities as well as addressing existing design flaws.
The new system was built to optimize the efficiency of the existing plan
and environmental results desired by Tishman Speyer.
The 41-tank system provides 8,600 ton hours of thermal storage, which allows the building to shift
peak cooling loads to off
Because of the New York climate, the system is able to conserve energy by reducing the load on the
primary heating, ventilation and air conditioning (HVAC) plant during winter and shoulder seasons
when cooling demands are low. In addition
