The ASHRAE Green Guide provides guidance to designers of HVAC&R Systems in how to participate effectively on design teams charged with producing green buildings. It also covers green design techniques applicable to related technical disciplines, such as plumbing and lighting, and it addresses how mechanical and electrical systems may interact with and be influenced by architectural design project and carries through to the resulting structures construction, operation and maintenance, and eventual demolition. This is a useful reference for architects, building owners, building managers and operators, contractors, and others in the building industry who want to understand some of the technical issues regarding high-performance design from an integrated building systems perspective.
