Everyone is concerned about bringing the proper amount of outside air into a building. ASHRAE Standard 62.1-1999 provides ventilation guidelines for various building types, and they’ve set the standard for what constitutes proper ventilation.
But there’s more to it than that. Although many buildings do rely on constant air volume, many more owners and operators are looking for variable air volume (vav) systems that can ensure a building is receiving the proper amount of outside air at any given moment.
