Even up-to-date Heating, Ventilation and A/C systems can consume as much as 30 percent of a building's energy. How can you get them to consume even less energy to reduce your operations expenses? You can control your Heating, Ventilation and A/C method based on real-time demand. If you're looking for ways to trim costs, your Heating, Ventilation and A/C method can be a enjoyable place to start. You can significantly reduce your facility's energy expenses by using more than 2 components of up-to-date Heating, Ventilation and A/C systems. With VAV boxes or terminal units, your office space can be more comfortable while consuming less energy. Older systems simply pump the entire volume of conditioned air into your home. Modern Heating, Ventilation and A/C systems incorporate VAV boxes, which use controlled dampers to vary air supply to control the temperature within a particular area. Considering underfloor air distribution for new construction is another way to provide customized comfort while reducing costs. Modern Heating, Ventilation and A/C systems use this distribution method to distribute conditioned air under a raised floor instead of overhead ducts. In some cases, fan-powered terminal units as well as ducts may also be used under the floor. Diffusers in the floor supply the air to the occupied space. Lighting sensors may be correct to you if you have been looking for ways to save energy in your facility. Using electronic sensors, these systems detect the presence of people in a room as well as turn the lights on as well as off according to when the space is occupied. With today's building automation technology as well as up-to-date Heating, Ventilation and A/C systems, these lighting sensors can be integrated with the Heating, Ventilation and A/C method to control heating as well as cooling based on actual occupancy as well as lighting. To get the most out of a up-to-date Heating, Ventilation and A/C system, even brand new systems need to be correctly tested from the start.
