Heating and cooling for most buildings are accomplished by chillers, boilers, or individually packaged split type systems. The average building ventilation system is 38% larger than necessary. Considering the ventilation systems alone can account for up to 80% of the energy use in a building, there is a huge potential for savings. Savings are not only achieved by reducing the load by replacing existing machinery with higher energy efficient equipment, our break-through engineering also covers efficiency modifications to the boilers and from sealing air-infiltration and improving insulation which can negate any heat losses. Optimizing the system and using Variable Frequency Drives (VFD’s) to match the load requirements will substantially increase savings and reduce operating costs. With our holistic approach, we can substantially reduce the cost of implementation by avoiding a ton-for-ton replacement of mechanical systems.
