Design and implementation of IoT-based HVAC system for future zero energy building

Zero energy building (ZEB) technologies are under investigation as a solution to problems of greenhouse gas emissions and energy depletion. Not only to solving energy problems, but also future ZEB needs to provide a comfortable environment for building occupants. A HVAC systems are significant parts of ZEB technologies. However, the existing HVAC systems have several problems. To solve the problem, in this paper, we propose a IoT-based HVAC system (I-HVACS) for indoor air quality (IAQ) management and reduction of building energy consumption. The I-HVACS is implemented and demonstrated in a real building which is a senior care center in Republic of Korea. The power consumption in the building is reduced by about 13.7% compared with the existing system.
