'The Importance and Understanding of having a Building Automation System Herbert Cuthbertson UAE210 — DIRECT digital CONTROLS In the past, there was little worry well-nigh energy consumption and costs associated with keeping Heating, Ventilation, line of reasoning Conditioning (HVAC), lighting and mechanical machines guide onning at all hours of the day and night possibly. But payable to the energy crises of the 1970’s and the last decade of acclivity costs of oil, the costs of energy not has laboured not only families to conserve energy but companies, schools and businesses as well.\r\nIn comes Direct Digital Controls (DDC) and/or Building Automation System (BAS) Basically a BAS/DDC system is a system that uses microprocessors, digital matchs, to control not only hvac, but security, lighting, paging, and telecommunications if necessary. I late spoke with a neighbor of mine who in the 1970’s worked for facilities management company representing various e difice in Cincinnati, Ohio. He explained to me that in the past, he and others, at the end of the day/night would have to go to every floor of these creates and physically switch impinge on the lights and hvac systems to try to conserve energy.\r\nWith a BAS system, a roach of that time could be eliminated. A BAS system smoke now turn on a particular(a) set of lights establish time, occupancy indicators, or an discloseback(a) light sensor. It can turn on and score a hvac system in a accredited area of the construct based on occupancy, countenance additional heating or cooling based on a afterhours switch on a thermostat, send out alarms to a facility technician, security, legal philosophy and fire military unit, and allow trained personnel to remotely access the system and change certain parameters or else of making a possible trip to the building.\r\n stop Maintenance (PM) on hvac equipment can also be integrated in the BAS. Instead of predicting the tote up of run ti me hours, the BAS can show the correct amount of run time hours and notify personnel when equipment is due for its preventive maintenance. This ensures the equipment is routinely serviced according to the equipment manufacturers schedule.\r\nIf a building does not have any BAS installed and management personnel is ready to invest in its installation, then this testament take a well thought out plan. This plan will need to be constructed by trained personnel who will do the subcontract correctly. This will enable both the building owners and the occupants of the building to enjoy the benefits of future financial gains and a to a greater extent comfortable building.\r\n'
