Tenant Energy Performance Optimization Case Study: Li & Fung USA, Empire State Building

CMI High Performance Tenant Demonstration Project

Li & Fung USA (LFUSA), a global consumer goods company, has committed to design and construct a high performance tenant space in the Empire State Building to reduce energy demand, increase efficiency, and improve indoor environmental quality. This paper summarizes how LFUSA, in close collaboration with the Natural Resources Defense Council's Center for Market Innovation (CMI), and the Empire State Building, evaluated an integrated, multi-component package of energy performance measures, which were then incorporated into the space design to achieve substantial, cost-effective energy savings, and corresponding carbon emissions reductions. The tenant project is the first in a series of case studies by CMI, aimed at demonstrating the energy and cost savings impact of high performance tenant design.
