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.

Quick Jumps

  • 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.
