Recent changes to ASHRAE Standard 90.1 require single-zone VAV systems in some applications. This ENL will review these new requirements, discuss the benefits of single-zone VAV systems (energy savings, better part-load dehumidification, and lower part-load sound levels), identify common applications for this system, and discuss ways to address application-related challenges (air distribution, demand-controlled ventilation, and building pressure control). In addition, we intend to review a case study of a retrofit project where a constant-volume rooftop unit was replaced with a single-zone VAV unit.
