Reduced Capital Cost

Most commercial buildings use significant amounts of equipment in order to mechanically ventilate and air-condition the interior. Sometimes the HVAC equipment, associated ductwork, grilles, diffusers, etc. can account for up to 30% of the capital cost of a new building. Naturally ventilated buildings, on the other hand, involve much less equipment and ductwork space, thus presenting designers with a means to reduce the overall cost of the building. Budget does need to be allocated for the natural ventilation equipment and controls, but should be less than that set aside for mechanically ventilated buildings.
