The views expressed in this report do not necessarily reflect the views of partner countries – United States of America and India – or the United States Agency for International Development. 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. More information as well as electronic copies of all the publications can be accessed at www.eco3.org. 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 of buildings. ECBC covers building envelope, heating, ventilation, and air conditioning system, interior and exterior lighting system, service hot water, electrical power system and motors. In May 2007, the Ministry of Power, Government of India formally launched the ECBC for its voluntary adoption in the country. Since then, BEE has been promoting and facilitating its adoption through several training and capacity building programmes. BEE is also monitoring implementation of ECBC through the ECBC Programme Committee (EPC). EPC also reviews periodically the inconsistencies and comments on ECBC received from various quarters. In this context, BEE in consultation with EPC and support from USAID ECO-III Project brought out a revised version of ECBC in May 2008. During the capacity building effort, a need was clearly felt to provide additional guidance to design and construction professionals on the rationale behind the ECBC specifications and provide explanations to the key terms and concepts governing these specifications so that people are able to comprehend ECBC in a better way. Considering this growing need for developing a better understanding of ECBC in the country, the ECBC User Guide has been prepared under the USAID ECO-III Project in close partnership with BEE. The document aims to guide and assist the building designers, architects and all others involved in the building construction industry to implement ECBC in real situations. The document is written both as a reference and as an instructional guide. It also features examples, best practices, checklists, etc. to direct and facilitate the design and construction of ECBC-compliant buildings in India. I am happy to note that the ECBC User Guide Development Team has made a concerted effort to provide all the information, especially minimum performance standards that buildings need to comply with, in one place. Consequently, it is my hope that users of ECBC trying to show compliance through the prescriptive path will find it easier to do so through the guidance provided in the document. The ECBC User Guide also provides additional guidance on the Whole Building Performance method by making references to international publications that are widely used by the building design community. I thank the entire ECBC User Guide Development Team, led by Dr. Satish Kumar, for its extensive efforts in bringing out this document. I would like to express my sincere appreciation to the USAID for providing this technical assistance under the ECO-III Project and to the International Resources Group for spearheading this team effort. 17th July, 2009 (Dr. Ajay Mathur) ECBC User Guide Development Team Satish Kumar, Team Leader IRG, USAID ECO-III Project Aleisha Khan, Alliance to Save Energy • Anurag Bajpai, IRG, USAID ECO-III Project • G.

I would like to thank Dr. Archana Walia, Project Manager, and Mr. S. Padmanaban of USAID for their constant encouragement and steadfast support during the development process. I would like to acknowledge the tremendous support and encouragement provided by Dr. Ajay Mathur, Director General, and Mr. Sanjay Seth, Energy Economist of BEE in the preparation of the Guide. A substantial undertaking of this nature would not have been possible without the extremely valuable technical contribution provided by the Development Team of ECBC User Guide especially Ms. Vasudha Lathey, Ms. Aleisha Khan of Alliance to Save Energy (ASE), Dr. Vishal Garg and Ms. Surekha Tetali of International Institute of Information Technology (IIIT), Prof. Rajan Rawal of Center for Environmental Planning and Technology (CEPT), Dr. Jyotirmay Mathur of Malviya National Institute Technology (MNIT), Mr. P. C. Thomas and Mr. G. S. Rao of Team Catalyst. I would like to acknowledge the assistance that the Development Team received from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Inc., USA. The 90.1 User Manual, ANSI/ ASHRAE/IESNA Standard 90.1-2004, provided us with a robust framework and a sound technical reference during the development of the ECBC User Guide. I am also thankful to Ms. Meredydd Evans of Pacific North- West National Laboratory (PNNL), and to Saint Gobain, DuPont, ASAHI-India, and Dr. Mahabir Bhandari (DesignBuilder) for providing inputs on many iterations of this document. I would like to convey my special thanks to the ECO-III Project Team – Mr. Ravi Kapoor for his substantial technical contribution to the development of the entire document, Mr. Anurag Bajpai for his tireless efforts in coordinating inputs from the Development Team members, and Ms. Meetu Sharma for her persistence efforts to prepare the graphics and desktop layout of multiple iterations of the document. Without the perseverance and discipline of ECO-III Project Team this work would not have been possible. I also like to thank Ms. Laurie Chamberlain of International Resources Group (IRG) HQ for assisting us in carrying out technical editing of this document. 17th July, 2009 (Dr. Satish Kumar) Chief of Party, USAID ECO-III Project International Resources Group How to Use This Guide The ECBC User Guide follows the same structure as the Energy Conservation Building Code. Consequently, Chapters 1 through 8 and Appendix A through G are identical to the ECBC chapters and uploads/s1/ ecbc-user-guide-public.pdf
