Design Methodology and Experimental Investigation of a Multiple-Inlet BIPV/T System in a Curtain Wall Facade Assembly and Roof Application
Building-integrated photovoltaic (BIPV) technologies are becoming a competitive alternative to traditional claddings as the building industry looks toward renewables for local energy sources. An advancement of the BIPV is the building-integrated photovoltaic/thermal (BIPV/T) system, which harvests excess heat produced by the photovoltaic panels and transfers it to a medium for useful energy. For application on large scale facades, air-based BIPV/T systems can be used in low temperature applications. However, due to a lack of installation and maintenance guidelines as well as insufficient performance standardization, both technologies have yet to experience widespread implementation. Additionally, tools for determining potential energy generation during the early design phase are complex and not readily available. This thesis provides a discussion, analysis and comparison of recent advancements in BIPV and BIPV/T systems in order to assess architectural and energy performance considerations for full facade integration. A BIPV/T design methodology was developed based on the investigation of three novel case studies involving both roof and facade applications. Issues of constructability, building envelope requirements, material compatibility, and maintenance were addressed. Subsequently, guidelines for a BIPV/T performance standard were suggested. Linking this research to the established criteria of current building practices, a BIPV/T prototype was constructed, adopting a conventional curtain wall frame. Base characterization testing was conducted at the Solar Simulator and Environmental Chamber (SSEC) testing facility at Concordia University to assess the prototype's electrical and thermal performance. Three different flow rates, the use of single or multiple inlets, and two different transparencies of photovoltaic modules were investigated for their effect on system performance. Results from the preliminary testing showed that the use of multiple inlets may increase the thermal output by up to 18%, decrease the peak photovoltaic (PV) temperatures by up to 3°C, and marginally increase the electrical output. While the experiments were a first step in confirming prototype functionality and for model verification purposes, there is a need to further explore the optimization of this design and its application on building typologies through simulation.

This book provides the most up-to-date information on hybrid solar cell and solar thermal collectors, which are commonly referred to as Photovoltaic/Thermal (PV/T) systems. PV/T systems convert solar radiation into thermal and electrical energy to produce electricity, utilize more of the solar spectrum, and save space by combining the two structures to cover lesser area than two systems separately. Research in this area is growing rapidly and is highlighted within this book. The most current methods and techniques available to aid in overall efficiency, reduce cost and improve modeling and system maintenance are all covered. In-depth chapters present the background and basic principles of the technology along with a detailed review of the most current literature. Moreover, the book details design criteria for PV/T systems including residential, commercial, and industrial applications. Provides an objective and decisive source for the supporters of green and renewable source of energy Discusses and evaluates state-of-the-art PV/T system designs Proposes and recommends potential designs for future research on this topic
Photovoltaics and Architecture
Photovoltaic systems (PVs) produce electricity directly from solar radiation and are becoming more widespread as their advantages become apparent. This new guide provides an overview of how PVs work and how they are incorporated in the design of buildings, giving designers a good idea of the variety and flexibility of PVs and of their design and aesthetic potential. Seven contemporary case studies illustrate the use and application of photovoltaic systems.
