Printed by NTNU Grafisk senter i This thesis concerns the use of solar energy in energy efficient buildings. More precisely, the topic is photovoltaic-thermal (PV/T) solar energy systems, and how these can be used to provide renewable energy in zero emission buildings. PV/T modules are a hybrid between photovoltaic (PV) modules and solar thermal collectors, and therefore generate electricity and thermal energy simultaneously. The objective of the thesis was to investigate the potential of PV/T systems to minimize the life cycle greenhouse gas emissions of a residential building.The building sector accounts for around one third of the global energy use and about half of the electricity use, and is therefore a key area to focus on in the effort to mitigate climate change and to create more sustainable societies in the future. The environmental impact of buildings need to be lowered by reducing the energy demand during construction and operation, but also by replacing polluting energy sources with renewable ones. The European Union has demanded of its member states that all new buildings shall be nearly zero energy buildings by 2020.Solar energy is well-suited to use in buildings, and can supply electricity, lighting, heating, and cooling. Once installed, a solar energy system supplies energy without pollution, is silent, have few or no moving parts, and can also be integrated into the building itself. In order to do investigate how PV/T systems can best be used in buildings to minimize life cycle emissions, the systems have been studied both in terms of energy performance and in terms of greenhouse gas emissions.The main research method in this thesis has been simulation of solar energy systems in buildings. Using simulations, PV/T systems have been compared to other solar energy systems with separate PV modules and solar thermal collectors. The simulation studies were performed in the simulation programs Polysun and PVsyst, and were based on commercial solar energy products available on the current market. The use of heat pumps, air-source and ground-source, in combination with solar energy systems was also studied.Two case buildings, the ZEB residential concept and the Living Lab, have been used in the simulation studies. The buildings are two of the pilot buildings of the Norwegian Research Centre for Zero Emission Buildings (the ZEB Centre). Both buildings are single family residential buildings located in Central or Southern Norway, and are designed to meet the Norwegian passive house requirements.The embodied emissions of the solar energy systems were determined using elements of life cycle assessments (LCA). A review of previous research found few studies of the environmental impact of PV/T modules, especially using industrially produced modules. The embodied emissions of such a PV/T module was therefore determined in this thesis, based on a combination of data from databases and information from module producers. The embodied emissions of the case buildings and the other solar energy systems studied were d...

“…It consists of flat-plate solar collectors, an external heat exchanger, a storage tank, and auxiliary heaters. In addition, this general configuration is also being employed and improved upon in other applications of solar energy systems, such as photovoltaic/thermal systems [17][18][19] and solar-driven heat and power systems [20]. The primary fluid, i.e., antifreeze fluid, circulates between the collectors and the hot side of an external heat exchanger.…”

Abstract:To maximize the energy performance and economic benefits of solar water heating (SWH) systems, the installation and operation-related design variables as well as those related to capacity must be optimized. This paper presents a novel design method for simultaneously optimizing the various design variables of an indirect forced-circulation SWH system that is based on the life cycle cost and uses a genetic algorithm. The effectiveness of the proposed method is assessed by evaluating the long-term performance corresponding to four cases, which are optimized using different annual solar fractions and sets of the design variables. When the installation and operation-related design variables were taken into consideration, it resulted in an efficient and economic design and an extra cost reduction of 3.2%-6.1% over when only the capacity-related design variables were considered. In addition, the results of parametric studies show that the slope and mass flow rate of the collector have a significant impact on the energy and economic performances of SWH systems. In contrast, the mass flow rate in the secondary circuit and the differences in the temperatures of the upper and lower dead bands of the differential controller have a smaller impact.

“…As such, it could be argued that the concentrator performs poorly when compared to purpose designed solar collectors with peak efficiencies in excess of 70%. However, this lower efficiency is due to the increased heat losses by radiation and convection in the absence of a glazing layer (Anderson et al, 2009) that reduce the thermal efficiency.…”

“…Previously Anderson et al (2009) had demonstrated the use of PVT collectors based on trapezoidal profiled long run metal roofs where passageways were formed in the trough of the roof profile for the thermal cooling medium to travel through. Subsequently, a cover having polycrystalline PV cells laminated to its surface was bonded into the trough, thus forming a tube to which heat could be transferred.…”

The idea of concentrating solar energy to increase the output of photovoltaic and solar thermal collectors is an area that has received significant attention. In this study, a design model for a V-trough concentrating photovoltaic/thermal solar collector was theoretically analysed and validated with experimental data.The results showed that the V-trough offered improved electrical yields from both concentrating radiation onto the photovoltaic cells and also by actively cooling them. Also, it was shown that the Vtrough could be made of a durable (long life) stainless steel, rather than the more reflective aluminium, while still offering a 25% increase in incident radiation over a typical year. However it was noted that modifications would be needed to improve cooling and to increase the thermal efficiency by reducing heat losses.
