When Venmar CES equipment is configured as a DOAS, energy consumption is significantly reduced (in some cases by up to 35% with certain energy efficient parallel systems) by decoupling the heating, cooling and dehumidification loads of the outdoor air from internal sensible heating and cooling loads of the space. Numerous papers have been written and compiled on the advantages of using these systems over traditional VAV designs.
Regardless of the high performance building standard or guideline, the advantages of using a Dedicated Outdoor Air System can significantly contribute to the success of a high performance building project. Dedicated Outdoor Air Solutions optimize energy performance, allow for increased ventilation and better OA modelling. DOAS can contribute to an improved indoor air quality plan during construction and prior to occupancy. In addition, DOAS can contribute to indoor pollutant and source control objectives, as well as provide better (and simpler) ability to meet requirements for thermal comfort.
Dedicated Outdoor Air Solutions also help to meet indoor air quality best practices in existing buildings, and ensure occupant comfort for the life of the building by supporting a well ventilated and well conditioned space which in turn improves satisfaction and productivity.
