Indoor environmental quality (IEQ), a concept often overlooked in building designs of the past, has only recently become an area of focus for the design community. With the recent growth of the sustainable design movement, many factors aimed at improving the health and wellbeing of the building occupant are gaining momentum. The principal standards and guidelines for HVAC system design and operation include (1) American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) Standard , “Ventilation for Acceptable Indoor Air Quality”; (2) American National Standards Institute (ANSI)/ASHRAE Standard , “Thermal Environmental. In an effort to provide SMACNA contractors, architects, engineers, building owners and managers, and the general construction industry with a researched, practical publication to assist in maintaining acceptable indoor air quality during building renovation, SMACNA’s Building Services Committee developed the first edition of the IAQ Guidelines for Occupied Buildings Under Construction.   heating,ventilation, and air conditioning (hvac)[1] isthetechnology of indoor andvehicular environmental comfort. its goal isto provide thermal comfort and acceptable indoor air quality. hvac system design is a sub discipline of mechanical engineering, based onthe principles of thermodynamics, fluid mechanics, and heat transfer.
