Design and Automation of a Zero-Energy Model House (ZEH)

Because of the rising energy prices, green-house effects, and environmental concerns, there has been a lot of emphasis on using alternative, renewable energy sources. This paper is concerned with the use of solar energy to meet the energy needs of a scaled model house. Photovoltaic (PV) panels are used to collect solar energy and convert it to electrical energy. In this experimental study, the design of a photovoltaic system is presented for a small model house along with its associated instrumentation, real time data acquisition and automation using NI ® LabVIEW. The study clearly shows that energy requirements can be met using renewable energy sources and that the goal of a zero energy house is attainable in many locations. This work was performed in partial fulfillment of the requirements of the Senior Capstone Project course in controls and instrumentation of the Engineering Technology department at the University of Houston Downtown and then was continued as research project as part of continuing education. Student experiences are summarized and the need for teamwork and effective project management methods is emphasized.
