Leadership in Energy and Environmental Design (LEED)

The LEED Green Building Rating System is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED gives building owners and operators the framework and guidance they need to have an immediate and measurable impact on their buildings' performance. LEED promotes a whole-building approach to sustainability by recognizing performance in six key areas of human and environmental health including sustainable site development, water savings, energy efficiency, materials and resources selection, indoor environmental quality, and innovation in design.

The two rating systems used for benchmarking the Empire State Building included the LEED for Existing Buildings: Operations & Maintenance rating system and the LEED for Commercial Interiors program.

Greenhouse Gas Inventory Tool for Buildings

The Sustainability Metrics Model for Greenhouse Gas Emissions has been developed by the project team to scientifically evaluate a facility or company's impact on global warming and local environment resulting from the implementation of sustainability measures. This tool will enable the Empire State Building, and other buildings, to quantify the impact of their sustainability initiatives by converting their impact to Global Warming Potential (GWP).

The quantitative tool is based on internationally accepted scientific data and calculations. Tools, information, and data developed and published by the EPA, EIA, WRI, and DOE are used to support the Sustainability Metrics Model. The model is Excel-based to allow ease of integration as the Model is shared.
