Advanced HVAC Systems for Improving Indoor Environmental Quality and Energy Performance of California K-12 Schools: Applications Guide for Off-the-Shelf Equipment for Displacement Ventilation Use.

Web Abstract: 
Provides background information on the potential energy use, indoor air quality and acoustic benefits of displaced ventilation as well as field experience with DV in schools and commercial buildings. The applications that could benefit from use of displacement ventilation are described including facility requirements, acoustic requirements, climate-related factors, and indoor air quality. Displacement ventilation system requirements for K-12 schools are defined, including diffuser requirements, HVAC requirements, and optional HVAC system features. Mechanical system options are described including central (chiller-based) plants, packaged direct expansion (DX) variable air volume systems and packaged single zone direct expansion units. Alternative control strategies are discussed and diffuser options are presented. Includes nine references.
