Building owners are caught between two powerful forces--the need to lower energy costs and the need to exceed outdoor air ventilation regulations for occupant health and comfort. Large amounts of energy are wasted each day as HVAC systems replace indoor air with fresh outdoor air multiple times per day. Heating or cooling energy is continually wasted in the exhaust air stream while new energy must be generated and used to condition entering outdoor air. Building owners who fail to capture this wasted energy will continue to incur high energy costs, negatively impacting property values, profi tability, and the ability to attract tenants with corporate or federally directed energy-effi ciency mandates. To address this challenge, many building owners are turning to site-recovered energy technologies such as energy recovery ventilation (ERV). INSET: FINDING ENERGY RECOVERY SYSTEMS FASHIONABLE.
