The ECBC User Guide has been developed to provide detailed guidance to building owners, designers, engineers, builders, energy consultants, and others on how to comply with the Energy Conservation Building Code (ECBC). The guide provides expanded interpretation, examples, and supplementary information to assist in applying ECBC during the design and construction of new buildings as well as additions and alterations to existing buildings. The Guide can also be used as a document by "authorities having jurisdiction" in the enforcement of the code. The guide follows the nomenclature of ECBC, it was written both as a reference and as an instructional guide, and can be helpful for anyone who is directly or indirectly involved in the design and construction of ECBC-compliant buildings.
