Technical-Economic Implementation of a Control and Supervision System in Air-Conditioning Systems Through BACnet for Energy Efficiency in Buildings

In coastal areas, the highest consumption of electricity is due to the use of air conditioners due to the high temperatures. Avoiding air conditioners being on when there are no personnel in the air-conditioned areas is one of the options that serve as a strategy to reduce electricity consumption. But turning the ACs on and off generates compressor start-up peaks, and this also generates an increase in electricity consumption. Therefore, in the present work, the control of the ACs through Building Automation and Control Networks (BACnet) communication is used for optimal control in various scenarios of the use of ACs. The test was implemented in the offices of a university showing savings in dollars of up to 55.6%, demonstrating energy efficiency in buildings because it is possible to adapt old technology equipment whose compressors start directly.
