Video: New-School HVAC Approach Improves Comfort and Air Quality for K-12 Students
When a 25-year-old HVAC system increased energy costs and negatively impacted the learning environment for students and teachers, the administrators at Monument School in Monument, Ore., sought a healthier and more efficient solution. Hear from school and utility staff members on how the very high efficiency DOAS approach to HVAC design dramatically reduced the rural K-12 school’s monthly energy costs, significantly improved their air quality, reduced viral spread, and provided a far more comfortable and productive learning environment.

With the ever-increasing environmental impacts of local pollution, extreme weather events and wildfires, there is a necessity for resilient, flexible, and extremely efficient HVAC systems. A very high efficiency (VHE) approach to DOAS maximizes energy efficiency by decoupling ventilation air from comfort conditioning, including air-to-air heat recovery, right-sizing of a high efficiency heating and cooling system and minimizing fan power.

The Bayview Tower project retrofitted an aging electric resistance water heating system in an occupied affordable housing high-rise located in Seattle. The new commercial heat pump water heating system at Bayview Towers marked the United States' first large-capacity CO2 refrigerant-based domestic water heating system. It is also the first installation of a load shift-capable commercial HPWH system nationwide.
