USAID ECO-III Project The Energy Conservation and Commercialization (ECO) Program was signed between the Government of India (GOI) and USAID in January 2000 under a bilateral agreement with the objective to enhance commercial viability and performance of Indian energy sector and to promote utilization of clean and energy-efficient technologies in the sector. Following the enactment of the Energy Conservation Act 2001, ECO-I Project supported GOI in the establishment of the Bureau of Energy Efficiency (BEE). Support to BEE was provided to set up procedures and authorities, establish office facilities and assist in several activities leading to the development of BEE’s Action Plan including thrust area such as the development of an energy auditor certification program. ECO-II Project provided BEE with necessary technical assistance and training support to implement three thrust areas of the Action Plan. The first area was to develop the Energy Conservation Building Codes (ECBC) for the five climatic zones of India, the second was to support Maharashtra Energy Development Agency in developing strategies for energy conservation and implementation of selected programs, and the third area focused on implementing a pilot DSM program to replace incandescent lamps with CFLs in the state of Karnataka in partnership with BESCOM. Since November 2006, International Resources Group (IRG), with support from its partners IRG Systems South Asia, Alliance to Save Energy and DSCL Energy Services, other partner organizations and consultants has been implementing the ECO-III Project by working closely with BEE, Gujarat Energy Development Agency, and Punjab Energy Development Agency. ECBC User Guide has been produced to assist Government of India in the implementation of ECBC, which was launched by Ministry of Power in May 2007. It is hoped that this document will help in creating awareness and enhancing understanding about the ECBC. ECO-III Project has developed Tip Sheets and Design Guides in the past to help in the ECBC implementation efforts.

Foreword The Energy Conservation Act, 2001(52 of 2001) empowers the Central Government under Section 14(p) read with Section 56(2)(l) to prescribe Energy Conservation Building Code (ECBC). The Code defines norms and standards for the energy performance of buildings and their components based on the climate zone in which they are located. Under the leadership of Bureau of Energy Efficiency (BEE), a Committee of Experts finalized ECBC in consultation with various Stakeholders in 2007, with an overall purpose to provide minimum requirements for the energy-efficient design and construction
