Better comfort and energy costs start with the right HVAC. Understand how heating, cooling and airflow all directly contribute to the energy efficiency and tenant comfort of your commercial building.
Condensing Rooftop Units (C-RTUs) Bring Promise of Higher Efficiency and Reduced Building Operating Costs
Rooftop units (RTUs)—HVAC appliances installed on building roofs—are commonly used in commercial applications due to their inherent convenience: RTUs package heating and cooling equipment together in a space that doesn’t take up precious real estate and is still accessible to technicians.Resources
Portland Restaurant Cooks Up Comfort and Energy Savings
When faced with an an older HVAC system that was causing tenant discomfort, Portland-based restaurant Verde Cocina turned to an innovative HVAC approach that would reduce their energy costs while improving their customer experience.
High-Performance HVAC Gets to Work for Utility Office
Flathead Electric’s district office is a single-story 1960s-vintage building with offices at the front and a combination of storage space and garage bays for utility trucks in the back. Their former HVAC system had been pieced together from several years of changes and modifications and it was no longer providing indoor comfort or an adequate level of heating efficiency. Flathead Electric took advantage of an innovative approach to HVAC they knew all to well—a very high efficiency dedicated outside air system (also referred to as very high efficiency DOAS).
Trapper Creek Dorm Snares Energy Savings for Good
The Trapper Creek Dormitory is a federal government work campus in rural Montana. When restricted airflow caused summertime overheating, ventilation issues, and unsafe C02 levels in their dormitories, the facility managers decided to partner with Ravalli Electric Co-op and Bonneville Power Administration to implement a high-performance HVAC conversion.
Condensing Rooftop Unit Field Study Summary Report
To better understand challenges and to evaluate field performance, user acceptance, reliability, and energy savings potential in the Northwest, NEEA partnered with local utilities and businesses to install and monitor four condensing rooftop units (C-RTUs). This report summarizes the field study results from those four units during the 2018/2019 heating season.

Very High Efficiency Dedicated Outside Air Systems
It’s rare for a solution to reduce costs and improve quality, but the very high efficiency dedicated outside air system (DOAS) does both by separating heating and cooling from the ventilation system. The DOAS can reduce commercial building energy use by an average of 36%, and saves roof space and ductwork, all while delivering 100% filtered outside air for maximum tenant comfort.
Condensing Gas Rooftop Units
Condensing gas rooftop units (C-RTU) are becoming more available and popular for commercial buildings where high efficiency and lower operating costs are attractive benefits. C-RTUs provide a big upgrade over traditional gas furnaces providing 10-15% higher heating efficiency and up to 11.5% reduction in gas energy usage.
