Retrofitting Older Apartment Buildings for Energy Efficiency: Practical Proposals for Public Housing in New York City

Professor Steven Cohen, Director of the MPA-ESP program as well as Executive Director and Chief Operating Officer of the Earth Institute, has been advising the team that is working with the New York City Housing Authority to embark on an effort to scale up its energy-efficient building retrofit efforts to an "enterprise" level. This workshop group was asked to describe and assess comparable efforts to enhance the energy efficiency of older multi-family residential buildings in order to provide a benchmark study of current potential technologies.
