Buildings consume a large amount of energy across all sectors of society, and a large
proportion of building energy is used by HVAC systems to provide a comfortable and healthy …

Abstract Cooling Load based Control (CLC) for the chiller sequencing is a commonly used
control strategy for multiple-chiller plants. To improve the energy efficiency of these chiller …

Heating, ventilation and air conditioning (HVAC) systems contribute to a major portion of
energy consumption in buildings. Real-time optimal control is an efficient tool to improve the …

Achieving the optimal control of cooling towers is critical to the energy-efficient operation of
current or legacy chiller plants. Although many promising control methods have been …

This paper describes a coupled dynamic simulation of an indoor environment with heating,
ventilation, and air conditioning (HVAC) systems, controls and building envelope heat …

Constant-speed air-cooled water chillers (CAWCs) are typically on–off controlled in
accordance with a fixed set point of chilled water return temperature (T wr), which seriously …

Real-time optimization (RTO) has been developed to improve the cost and/or energy
efficiency of complex heating, ventilation and air-conditioning (HVAC) systems. In current …

Cooling load prediction is indispensable to many building energy saving strategies. In this
paper, we proposed a new method for predicting the cooling load of commercial buildings …

Abstract Model-based optimal demand-controlled ventilation (DCV) for multizone variable
air volume (VAV) systems has significant potential for reducing energy consumption and …

In this paper, we consider the optimal operations of a thermal system for heat source and air
conditioning system with a thermal storage tank using nonlinear programming. Firstly, we …
