Trane: Single-Zone VAV Systems

October 23, 2014 By Linda Hardesty

Changes to ASHRAE Standard 90.1 require single-zone variable air volume (VAV) in some applications. This video reviews these new requirements, discuses the benefits of single-zone VAV systems (energy savings, better part-load dehumidification, and lower part-load sound levels), identifies common applications for this system, and discusses ways to address application-related challenges (air distribution, ventilation, and building pressure control). In addition, it reviews a case study of a retrofit project where a constant-volume rooftop unit was replaced with a single-zone VAV unit. Trane presenters John Murphy, Eric Sturm and Jeanne Harshaw with guest Hakim Yala, Walgreens.
