Special Issue Information

Dear Colleagues,

In the late 80’s, a group of HVAC scientist and engineer proposed building commissioning to ensure that system performance met design specifications and has developed building commissioning technology, which is an ongoing process to resolve operating problems, improve comfort, optimize energy use and identify retrofits for existing commercial and institutional buildings and central plant facilities. This Special Issue invites original research in the area of recent research and development efforts in design, modeling and optimization aspects of energy and environmental systems for building energy audit, assessment and commissioning, such as Heating, ventilating and air conditioning(HVAC) system, renewable energy and passive system, smart and intelligent building, building automation control and operation, building energy management system(BEMS), fault detection diagnosis(FDD) and calibration and sustainable and net-zero energy buildings. Topics of this Special Issue include but are not limited to the following specific issues:

  • Building automation control and operation
  • Building energy audit, assessment and commissioning
  • Building energy management System(BEMS)
  • Building HVAC system
  • Fault detection diagnosis(FDD) and calibration
  • Heating, ventilating and air conditioning(HVAC) system
  • Machine and deep learning control
  • Renewable energy and passive system
  • Sustainable and net-zero energy building
  • Smart and intelligent building
  • Smart sensors for indoor air monitoring
  • Human comfort and indoor environmental quality
  • Ventilation and air circulation
  • Artificial intelligence and neural network
  • Building energy and environmental control
  • Building energy systems design, modeling and optimization

As global warming accelerates due to greenhouse gas emissions, more efforts are required to reduce greenhouse gas emissions. One of the methods used to save building energy is the efficient management of building mechanical systems. The economizer control of HVAC systems is an energy-efficient measure that improves operating methods by introducing outdoor air to save cooling energy when the outdoor-air temperature is sufficiently low. When the HVAC system is operated using economizer control, cooling energy can be saved, and the set-point of the mixed-air temperature is kept constant. Several studies are being conducted on the saving of energy using economizers. Although various studies have been conducted on the control of economizers, there is insufficient research dealing with the optimal control of mixed-air temperature in economizers that consider real-time changes. Therefore, in this study, predictive model-based mixed-air temperature optimization for a single-duct VAV system was constructed. For this, an ANN (Artificial Neural Network) that could be analyzed regardless of the variables was applied to predict the load and energy consumption and a simulator was constructed for the optimized mixed air temperature of the system. The predictive model-based control was evaluated in terms of its thermal comfort and energy, along with the existing economizer control. According to the application of the optimal economizer control, the energy consumption of the building was reduced by 28.9% compared to the existing dry-bulb temperature control, and was within ±1 °C of the indoor-air temperature set point.

In a heat pump system, performance is an important indicator that should be monitored for system optimization, fault diagnosis, and operational efficiency improvement. Real-time performance measurement and monitoring during heat pump operation is difficult because expensive performance measurement devices or additional installation of various monitoring sensors required for performance calculation are required. When using a data-based machine-learning model, it is possible to predict and monitor performance by finding the relationship between input and output values through an existing sensor. In this study, the performance prediction model of the air-cooled heat pump system was developed and verified using artificial neural network, support vector machine, random forest, and K-nearest neighbor model. The operation data of the heat pump system installed in the university laboratory was measured and a prediction model for each machine-learning stage was developed. The mean bias error analysis is −3.6 for artificial neural network, −5 for artificial neural network, −7.7 for random forest, and −8.3 for K-nearest neighbor. The artificial neural network model with the highest accuracy and the shortest calculation time among the developed prediction models was applied to the Building Automation System to enable real-time performance monitoring and to confirm the field applicability of the developed model.
