This dissertation research investigates on energy optimal operations of heating, ventilation and air conditioning (HVAC) systems for residential and commercial buildings, with investigations on two classes of approaches, i.e. Self-optimizing Control (SOC) based control structure optimization and Extremum Seeking Control (ESC) based real-time optimization, as well as their synergy. As the preliminary study, three existing ESC methods are compared, i.e. the conventional dither ESC, input-output correlation ESC (IOC-ESC), and proportion-integral ESC (PI-ESC). The primary goal for this study is to evaluate the performance robustness of each ESC to parametric variation. The three ESC strategies are first evaluated with simulation study using a Modelica model of an air source heat pump (ASHP) model. Then, laboratory tests are conducted with IOC-ESC and CON-ESC on a mini-split air conditioning system. Both simulation and experimental results show that PI-ESC archives fastest convergent speed, while IOC-ESC is most robust to parametric variation among three methods. For plant operation with multiple potential inputs for ESC design, an ESC integrated online input selection approach is proposed based on Hessian estimation and SVD analysis. The dimensionality of manipulated inputs can be reduced by pruning and/or combining the available manipulated inputs. Error bound analysis is conducted for the proposed input selection process. Then, the proposed procedure is validated with both numerical example and a Modelica based chilled-water plant model. The SOC based control structure optimization is studied from three perspectives, with the key focus of how to determine the optimal selection of controlled variables (CVs) with online or historical data. First, an online local SOC procedure is proposed by using the ditherdemodulation based gradient and Hessian estimates that have been developed in ESC, and the proposed method is validated with the Modelica ASHP model. Secondly, a data-driven global SOC method is proposed by applying the technique of sparse identification for nonlinear dynamics (SINDy) to historical data. For the static plant model thus derived, tracking the necessary condition of optimality yields the globally optimal solutions of CV selection in an analytical fashion. Such SOC framework is validate with the Modelica-based chilled-water plant operation. Then, this data-driven global SOC approach is extended to plant operation with wide range of disturbance variations which is subject to the changes of active constraint set. With the plant model obtained by the SINDy based procedure, a parametric programming enabled constrained optimization framework is utilized to derive the controlled variables for each region of different active constraint set. Again, simulation based validation is conducted with the Modelica based chilled-water plant model.

Energy usage and consumption continue to rise globally each year, with the most efficient and cost-effective energy sources causing huge impacts to the environment. In an effort to mitigate harmful effects to the environment, implementing clean energy resources and utilizing green energy management strategies have become worldwide initiatives, with many countries from all regions quickly becoming leaders in renewable energy usage. Still, not every energy resource is without flaws. Researchers must develop effective and low-cost strategies for clean energy in order to find the balance between production and consumption. The Research Anthology on Clean Energy Management and Solutions provides in-depth research that explores strategies and techniques used in the energy production field to optimize energy efficiency in order to maintain clean and safe use while delivering ample energy coverage. The anthology also seeks solutions to energy that have not yet been optimized or are still produced in a way that is harmful to the environment. Covering topics such as hydrogen fuel cells, renewable energy, solar power, solar systems, cost savings, and climate protection, this text is essential for electrical engineers, nuclear engineers, environmentalists, managers, policymakers, government officials, professionals in the energy industry, researchers, academicians, and students looking for the latest research on clean energy management.

Today's buildings are responsible for more than 40% of the world's total energy consumption. Current systems that manage equipment in buildings fail to reduce unnecessary energy consumption while at the same time maintaining the comfort of those using the buildings. This is usually because the existing systems cannot cope with the changes caused by interactions between people and the building environment. Furthermore, people using buildings are not sufficiently aware of how much buildings consume and of what concrete actions could help to reduce this consumption. Moreover, current building management systems do not take into account feedback from building users and their preferences regarding the conditions in their working environment. We designed and implemented a smart energy system to overcome these gaps. Our system took into account the behavior of building users so as to provide automated control of energy consumption and other processes within an actual building. With this system we also provided user dashboards to serve as a means of communication between the building and its users. In addition to reducing energy consumption we also introduced related optimizations such as reduction of water consumption and improvement of waste management, using the same system principles. We installed a prototype of this system in a modern university building, the Bernoulliborg, to show how such a system is realizable in actual working office space. This building served as the evaluation platform for our research.
