Personalized and Adaptive HVAC Control Strategies in Grid-Interactive Buildings
Efficient control of HVAC (Heating, Ventilation, and Air Conditioning) systems is crucial for balancing demand and supply of energy in buildings, particularly during peak demand pe-riods. This dissertation aims to address three research gaps. First, previous research effortshave focused on …

Thermal room modelling adapted to the test of HVAC control systems
Room models, currently used for controller tests, assume the room air to be perfectly mixed. A new room model is developed, assuming non-homogeneous room conditions and distinguishing between different sensor positions. From measurement in real test rooms and detailed CFD simulations, a list of …

Coupling simulation with machine learning for the development of a proactive HVAC system in the manufacturing sector
… [1]. Following manufacturing processes, the HVAC system is the second largest energy consumer in manufacturing facilities, yet is generally uncounted for and considered an indirect cost to maintain a facility [2]. Any current efforts at reducing energy demand in the manufacturing sector have …

Dynamic performance of control loops and their interactions in a VAV HVAC system
Good HVAC control schemes in buildings help reduce energy use and maintain occupant comfort. During the last 10 years, VAV-HVAC systems are widely used in commercial buildings because they can reduce energy use significantly and provide good temperature control of the conditioned spaces compared to …

Local energy management through mathematical modeling and optimization
… charge model, used for making daily optimal control decisions when the electric bill includes a charge based on the monthly maximum power draw. The problem of heating, ventilation, and air conditioning (HVAC) control is treated separately since it strongly violates TOTEM's linearity …

PI-control in dual duct systems : a study on manual tuning and control loop interaction
Good HVAC control schemes in buildings help reduce energy use and maintain occupant comfort. PID controllers are widely used in commercial buildings to keep variables such as temperature, pressure and humidity at predefined setpoints. These controllers, when they do not include autotuners, must be …

DESIGN, THERMAL SIMULATION AND ECONOMIC FEASIBILITY ANALYSIS OF A PLANT FACTORY HOUSED IN A UNDERGROUND MINE DRIFT
… it is necessary to produce sufficient food where controlled environment agriculture would be a potential solution but restricted due to energy intensiveness. Producing vegetables in underground mine tunnels in the underground plant factory (UGPF) could reduce energy consumption of plant factories …

Decentralized HVAC Operations: Novel Sensing Technologies and Control for Human-Aware HVAC Operations
… Heating, Ventilation, and Air-Conditioning (HVAC) HVAC operations. It has been envisioned that development of personal thermal comfort profiles leads to accurate predictions of each occupant's thermal comfort state and such information is employed in context-aware HVAC operations for energy …

Algorithms and Simulation Framework for Residential Demand Response
… a set of efficient algorithms that intelligently controls the customers' heating, ventilating and air conditioning (HVAC) devices for providing DR services to the grid. The second solution is an extensible residential demand response simulation framework that can help evaluate and experiment with …
