HVAC system designs must address both high indoor air quality as well as energy efficiency as the awareness of and demand for proper air quality increases. Economic considerations such as installation and operating costs have impaired many conventional system designs to the point of compromised indoor air quality. This paper discusses many HVAC design parameters that arc critical to achieving adequate indoor air quality. Topics include location of building fresh air intakes and exhaust air outlets, economizer systems, airflow tracking, filtering systems, sound attenuation, humidification systems, room air distribution, coil drain pans and condensate traps, duct zoning, localized exhausts, and temperature and humidity control.
