Sustainability

Sustainable Design

Tishman Speyer instituted an established four-step approach to reduce energy consumption, in particular peak energy usage. In a city where energy shortages can be a concern, especially in the summer months, reducing strain on the power grid is essential.
In adopting a systematic approach, Tishman Speyer has successfully reduced energy consumption across the entire complex, reducing operating expenses as a result.
This is a significant outcome in a city where infrastructure is stretched considerably beyond capacity. As an added benefit, Tishman Speyer has been able to pass savings on to its tenants.

LED Lighting

To reduce operational costs and the overall carbon footprint of Rockefeller Center, Tishman Speyer is nearing completion of an ambitious LED lighting installation plan. Offering measurable savings to tenants, as well as making the buildings easier to maintain, this program has already resulted in considerable energy savings.

Solar Energy

Tishman Speyer installed a 363-panel, 61 kW solar array atop 45 Rockefeller Plaza. Located 45 stories above ground, this is the largest privately owned rooftop PV installation in the city, and one of the highest in the world. The installation feeds a 60kW inverter where the energy is converted to high-quality 480 VAC power, which is then fed back into Rockefeller Center’s grid.

Ice Storage

Ice storage provides a cost-efficient way to cool commercial and retail buildings, while optimizing the power grid. Tishman Speyer installed a cutting-edge, 1,300-ton (4,600 kW) chiller feeding 41 ice storage tanks: each tank is 11 feet high and 7.5 feet in diameter. This reduces peak cooling requirements, saving on energy, C02 and costs.
