Direct Digial Control (Building Automation)

The Importance and Understanding of having a Building Automation System Herbert Cuthbertson UAE210 DIRECT DIGITAL CONTROLS In the past, there was little worry close to energy consumption and costs associated with keeping Heating, Ventilation, Air Conditioning (HVAC), lighting and mechanical machines slide byning at all hours of the day and night possibly. But cod to the energy crises of the 1970s and the last decade of salary increase costs of oil, the costs of energy not has forced not only families to conserve energy that companies, schools and businesses as well.In comes Direct Digital Controls (DDC) and/or Building Automation System (BAS) Basically a BAS/DDC system is a system that uses microprocessors, digital controls, to control not only hvac, but security, lighting, paging, and telecommunications if necessary. I belatedly spoke with a neighbor of mine who in the 1970s worked for facilities management company representing various mental synthesis in Cincinnati, Ohio. H e 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 buildings and physically switch wrap up the lights and hvac systems to try to conserve energy.With a BAS system, a fold of that time could be eliminated. A BAS system can now turn on a peculiar(prenominal) set of lights based time, occupancy indicators, or an prohibitedside light sensor. It can turn on and off a hvac system in a certain area of the building based on occupancy, bring home the bacon additional heating or cooling based on a afterhours switch on a thermostat, send out alarms to a facility technician, security, police and fire personnel department, and allow trained personnel to remotely access the system and change certain parameters instead of making a possible trip to the building. contraceptive Maintenance (PM) on hvac equipment can also be integrated in the BAS. Instead of predicting the amount of run time 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.If a building does not have any BAS installed and management personnel is ready to invest in its installation, then this will take a well thought out plan. This plan will need to be constructed by trained personnel who will do the line of credit correctly. This will enable both the building owners and the occupants of the building to enjoy the benefits of future financial gains and a more comfortable building.
