The impacts of ASHRAE Standard 62-1989 on a typical Florida elementary school were studied by performing annual building energy simulations using computer software. A single prototypical school was modeled for three cities: Miami, Orlando, and Jacksonville. The performance of a conventional heating, ventilating, and air-conditioning (HVAC) system and several alternative technologies was investigated to assess their ability to mitigate the impacts of ASHRAE Standard 62-1989 while maintaining acceptable indoor humidity levels. In addition, the installed first costs and life-cycle costs for all HVAC systems investigated were estimated and compared to identify cost-effective options. The results of this simulation study clearly indicate that the conventional HVAC system will have problems maintaining proper indoor humidity levels in Florida schools with ventilation rates prescribed by ASHRAE Standard 62-1989. Dedicated conditioning of outdoor ventilation air with alternative technologies would provide better humidity control in the occupied zones. Several of the alternative systems would also reduce the impacts of increased ventilation on equipment capacity, operating costs, and peak electric demand compared to the conventional system. All of the alternative HVAC systems studied are commercially available, and this study presents their performance in terms of ability to maintain acceptable indoor humility levels and life-cycle costs.
