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.

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

    Dedicated outside air systems (DOAS) separate heating and cooling from the ventilation system to allow for optimal control of each of these critical building functions. Building on the DOAS concept, a very high efficiency DOAS includes heat recovery ventilation and focuses on increased equipment efficiency and optimized system design. When compared to a code-minimum system upgrade, very high efficiency DOAS can reduce commercial building energy use by an average of 36%, and HVAC energy use by an average of 65%.

  • Condensing Gas Rooftop Units

    Condensing rooftop units (C-RTUs) have recently entered the commercial RTU market, providing the benefits of non-condensing RTUs at much higher efficiency levels and lower operating costs. Compared to a traditional gas furnace, C-RTU's have a 10-15% higher heating efficiency and up to 11.5% reduction in gas energy usage.
