<abstract> Growing energy demand has exacerbated the issue of energy security and caused us to necessitate the utilization of renewable resources. The best alternative for promoting generation in Bangladesh from renewable energy is solar photovoltaic technology. Grid-connected solar photovoltaic (PV) systems are becoming increasingly popular, considering solar potential and the recent cost of PV modules. This study proposes a grid-connected solar PV system with a net metering strategy using the Hybrid Optimization of Multiple Electric Renewables model. The HOMER model is used to evaluate raw data, to create a demand cycle using data from load surveys, and to find the best cost-effective configuration. A sensitivity analysis was also conducted to assess the impact of differences in radiation from the solar (4, 4.59, 4.65, 5 kWh/m2/day), PV capacity (0 kW, 100 kW, 200 kW, 300 kW, 350 kW, 400 kW, 420 kW), and grid prices (＄0.107, ＄0.118, ＄0.14 per kWh) upon that optimum configuration. Outcomes reveal that combining 420 kW of PV with a 405-kW converter and connecting to the utility grid is the least expensive and ecologically healthy configuration of the system. The electricity generation cost is estimated to be 0.0725 dollars per kilowatt-hour, and the net present value is 1.83 million dollars with a payback period of 6.4 years based on the system's 20-year lifespan. Also, compared to the existing grid and diesel-generator system, the optimized system, with a renewable fraction of 31.10%, provides a reduction in carbon dioxide emissions of 191 tons and 1,028 tons, respectively, each year. </abstract>

<abstract> The electricity demand has increased to 240% during the last decade in the Sultanate of Oman due to population growth and industrial expansion. Solar energy can act as an alternate source of energy production to meet the surge in demand for electric power. Also, the government has planned to derive 30% of the electricity from renewables by 2030. Moreover, agreements have been made to reduce greenhouse gas (GHG) emissions by decreasing 7% by 2030. The main objective of this paper is to design a grid-connected PV solar system based on the real-time data collected from the location called Nizwa, Oman using Hybrid Optimization of Multiple Electric Renewables (HOMER) software. The real-time data of average high and low temperature, solar radiation, estimated monthly average daily sunshine and peak hours of solar radiation of Nizwa has been collected from Meteorological Office Oman for January to December 2022. Nizwa recorded a temperature max of 43 ℃ during summer and 12 ℃ in January. Daily sun radiation in July averages between 5,500 and 6,000 Wh/m2, and the average sunshine is 9 hours per day at the selected project area (Nizwa). The collected data has been analyzed and designed using HOMER software. HOMER is used to model, optimize and analyze an integrated energy system that primarily utilizes renewable and non-conventional resources for both grid connected and autonomous systems. A 9-kW grid-connected PV solar panel has been designed and implemented in the proposed system. The proposed PV solar system worked perfectly and gave the results of an estimated number of hours of operation to be 4,362 hrs/year; the cost of energy per kilowatt is ＄ 0.044 and the annual energy saving cost of the hybrid system is ＄ 173.696. For the environmental feasibility of producing 14,765 kWh/yr, carbon dioxide emissions have decreased from 7,230,440 g to 4,396.001 g, with a difference of 7,226,043.9 g of carbon dioxide. </abstract>

This study evaluated the energy saving potential of renewable energy generation systems based on integrated solar energy in an urban environment. The solar city concept was implemented using photovoltaic (PV) and solar thermal systems. As a case study, the Sejong national pilot smart city in South Korea was selected to evaluate the renewable energy penetration rate. For evaluating the proposed renewable energy systems, the electrical and thermal loads of the smart city were estimated using field measurement data. Then, the renewable energy penetration rate of the city was evaluated. The HomerPro software was used to analyze the PV generation and operating energy consumption of the natural gas (NG) generator with a district heating network. The thermal load-supporting potential of the solar thermal system was estimated using the TRNSYS software. The results showed that the proposed urban integrated renewable energy system could meet over 30% of the renewable energy penetration rate and the levelized cost of energy and total net present cost was 7% lower than the base case system (i.e., NG generator). The proposed system also exhibited 38% less CO2 emissions than the base case system.

A sustainable and environmentally alternative to commonly used air conditioning systems can be the solar cooling system due to the use of renewable and clean energy. Solar absorption systems can be used for greenhouse cooling in areas with high outdoor temperatures and solar radiation levels. These systems take advantage of the simultaneity between the solar energy availability and the greenhouse cooling demand allowing the reduction of conventional electricity and water consumption. This paper presents the results of the application of a solar cooling plant for the climate control of a greenhouse at the University of Bari, Italy. The experimental plant consists of a Mediterranean greenhouse, having a surface of 300 m2, and of a single effect LiBr-H2O absorption chiller fed by evacuated-tube solar collectors. Two different localized systems were chosen for the distribution of cold inside the greenhouse: the first system presents pipes placed centrally on the cultivation vessels; the second consists of pipes in contact with aluminium plates and of a transparent EVA film, used to border an area close to plants. The distribution system of cold with pipes, plate and EVA film provided a slightly higher cooling capacity due to the presence of the plates which increases the ability to dissipate energy.

The Main objective of this project is to develop a power management system that will control the power flow and energy demand of an integrated renewable energy system with the focus on solar energy and wind energy. These storage systems are needed to provide high reliability and control systems are necessary for the stable and optimal operation of the whole system. The voltage and frequency of the line side converter are controlled with indirect vector control with droop characteristics. The setting of frequencies varies according to the battery energy level, which slows down when the battery is charged or discharged. The system can also work if the wind power source is not available. An Intelligent Power Management System (IPMS) is developed to handle various changes in power supply and power demand by managing erratic power and providing a suitable control algorithm for the whole system. In order to test various power supply and power demand using a power system. The performed simulations confirm the ability of the IPMS to satisfy the load at all times using solar and wind power (which are unsteady renewables), through the support of batteries.

This paper proposed a standalone solar/wind/micro-hydro hybrid power generation system to electrify Ethiopian remote areas that are far from the national utility grid. The aim is that it will lead to the development of renewable energy sources, using a hybrid optimization model for energy renewables (HOMER) as an optimization and sensitivity tool and MATLAB as a design tool. The system uses 100% renewable energy. This system incorporated solar photo-voltaic (PV), wind turbines, micro-hydro systems, and battery systems. The net present cost of the system is $4,377,731, incorporating capital depreciation and levelized operation and maintenance costs. During the hybrid energy system’s lifetime, the cost of a grid extension power supply is $22.185 million, which is nearly $17,808,000 more than the cost of the proposed standalone system. So, developing solar/wind/micro-hydro hybrid power generation will save $17,808,000 versus extending the national utility grid. As a result of a thorough examination of renewable energy resources, standalone solar, wind, and micro-hydro hybrid power generation is a technically and economically viable option for the case study area of Maji town.

Abstract: The utilization of renewable energy is significantly important for the world because global energy consumption is increasing, while conventional energy sources are no longer sufficient to meet the energy demand, triggering energy crises. In recent years, the increasing prices of fossil fuels and concerns about the environmental consequences of greenhouse gas emissions have renewed the interest in the development of alternative energy resources. Renewable energy is now considered a more desirable source of fuel than nuclear power due to the absence of risk and disasters [1]. Considering that the major component of greenhouse gases is carbon dioxide, there is a global concern about reducing carbon emissions. In this regard, different policies could be applied to reducing carbon emissions, such as enhancing renewable energy deployment and encouraging technological innovations. There are various of renewable energy sources such as Solar, biomass, wind, hydrogen, fuel cell, nanocomposite, and supercapacitor. Each of the energy sources are suitable for specific geographical locations and can suits from region to region. However, variation in solar radiation and wind speed caused by climate and weather conditions restricts the stable operation of renewable energy systems, therefore, causing the output to fluctuate. A hybrid renewable energy generation system can be highly efficient by combining multiple renewable energy sources and is regarded as a promising solution to overcome from this issue. Hybrid solar systems are the systems combining two renewable sources of energy, like solar and wind. Then, energy is generated through solar on sunny days and when there is limited sunshine but there is wind, energy can be generated through it. The study aims to focus on generation of hybrid solar-wind power plant with the optimal contribution of renewable energy resources supported by battery energy storage technology. The motivating factor behind the hybrid solar–wind power system design is the fact that both solar and wind power exhibit complementary power profiles. Advantageous combination of solar and wind with optimal ratio will lead to clear benefits for hybrid solar-wind power plants such as smoothing of intermittent power, higher reliability, and availability. However, the potential challenges for its integration into power grids cannot be neglected. A potential solution is to utilise one of the energy storage technologies, though all of them are still very expensive for such applications, especially at large scale. Therefore, optimal capacity calculations for energy storage system are also vital to realise full benefits. Currently, battery energy storage technology is considered as one of the most promising choices for renewable power applications. However, solar-wind power technology are most suitable for off-grid services, serving the remote are without having to build or extend expensive and complicated grid infrastructure. Therefor standalone system using renewable energy sources have become a preferred option. Hence hybrid energy systems are an ideal solution since they can offer substantial improvements in performance and cost reduction and can be tailored to varying end user requirements

AN ABSTRACT OF THE DISSERTATION OFLaith A. Zeinaldeen, for the Doctor of Philosophy degree in AGRICULTURAL SCIENCES – Renewable Energy, presented on November 2, 2020, at Southern Illinois University Carbondale.TITLE: ESTIMATING THE PERFORMANCE OF HYBRID (MONOCRYSTALLINE PV - COOLING) SYSTEM USING DIFFERENT FACTORSMAJOR PROFESSOR: Dr. Logan O. ParkAmbient temperature significantly affects photovoltaic (PV) panel performance. High temperature reduces PV panel efficiency, fill factor, and maximum power, driving up solar electrical system investment return period by increasing startup cost. Using a proper cooling system to cool down the PV panel temperature, especially during the summer season, will improve the PV panel performance, enhance its longevity, and accelerate the startup cost recovery to the solar electrical system. This dissertation presents two studies about monocrystalline PV panels. The studies used two general objectives: (i) study the best cooling period and water nozzle type to improve the monocrystalline PV panel output; and (ii) evaluating the performance of the monocrystalline PV panel using different cooling systems, other water pump discharge, and various water types during different times of day. In the first study (chapter 4), an experiment was conducted during July 2018 to determine Effect of using different cooling periods and different water nozzle types on the fill factor, efficiency, and the maximum power of monocrystalline PV panel. This experiment used two factors. The first factor was the cooling periods, which included three levels of PV panel cooling periods (5, 15, and 30 minutes). The second factor was water nozzle type: hollow cone and flat fan.In the second study (chapters 5, 6, and 7), an experiment was conducted during July and August 2018 to determine Effect of using different factors on the performance of monocrystalline PV panel at a site belong to the College of Agriculture – Southern Illinois University in Carbondale, IL. This experiment used four factors. The first factor was the time of day, the second factor was the cooling system, the third factor was the water pump discharge, and the fourth factor was the water type. The present studies' principal findings were: (i) the first experiment, the 15 minutes cooling period achieved the highest PV panel fill factor (0.795). In comparison, the 30 minutes cooling period reached the highest panel efficiency (18.6%) and maximum power (92.5 Watt). In contrast, the 5 minutes cooling period achieved the lowest PV panel fill factor (0.720), lowest panel efficiency (12.9%), and most insufficient panel maximum power (63.5 Watt). The hollow cone water nozzle achieved the highest panel fill factor (0.783), highest panel efficiency (16.60%), and the most elevated PV panel maximum power (82.8Watt). Interaction between the cooling and water nozzle types was non-significant on PV panel fill factor, significant on panel efficiency, and highly significant on PV panel maximum power. The interaction results between the cooling period and nozzle type demonstrate that the hollow cone nozzle with 30 minutes cooling period achieved the highest panel fill factor, highest panel efficiency, and the most elevated panel maximum power. The flat fan with a 5-minute cooling period achieved the lowest fill factor, lowest panel efficiency, and most insufficient panel maximum power. Tukey test results showed a highly significant difference (P < 0.0001) between the cooling period and the control treatment, and between the nozzle type treatment and the control treatment on panel fill factor, efficiency, and panel maximum power. Cooling periods have the most considerable effect on panel fill factor, panel efficiency, and maximum panel power, followed by the nozzle type. (ii) The second experiment results showed, the first cooling system (HC1) achieved the highest PV panel maximum power (77.0Watt), highest fill factor (0.745), highest PV panel efficiency (14.75%), highest average net energy (39.5Wh), highest PV panel energy (189.0 Wh) and highest average power gain (34.6Watt) comparing to the rest of the cooling systems. In comparison, the fourth (FtF2) achieved the lowest maximum power (58.0 Watt), lowest fill factor (0.653), lowest average efficiency (11.6%), lowest average net energy (-4.0Wh), lowest average energy (147.5Wh), and lowest average power gain (17.5 Watt). The fifth cooling system (SP) achieved the least average water consumption (2.0 L / hr.), while the second cooling system (HC2) achieved the highest average water consumption (39.0 L / hr.). The medium water pump discharge (M) produced the most elevated PV panel maximum power (67.6 Watt), highest fill factor (0.709), highest average PV panel efficiency (13.28%), highest average PV panel net energy (18 Wh), highest average PV panel energy (169.0Wh) and the highest average PV panel power gain (25.9Watt). High water pump discharge (H) achieved the lowest maximum power (63.8Watt), lowest average panel efficiency (12.48%), lowest average net energy (7.5Wh), lowest average panel energy (159.5Wh), and the lowest average power gain (21.8 Watt). The low water pump discharge (L) achieved the lowest panel fill factor (0.698). Lake water achieved the highest panel maximum power (66.1Watt), lowest PV panel fill factor (0.698), highest panel efficiency (12.94%), lowest net energy (12.8 Wh), highest panel energy (165.2 Wh), and lowest power gain (23.5Watt). In contrast, city water achieved the most elevated PV panel fill factor (0.708), most insufficient panel maximum power (64.8 Watt), highest average PV panel net energy (14.8 Wh), lowest efficiency (12.62%), highest average PV panel power gain (24.25 Watt) and lowest panel energy (162.1 Wh). Tukey post hoc difference testing showed highly significant differences (P < 0.0001) between the time of day, cooling system, water pump discharge, water type treatments, and their control treatment on PV panel maximum power, fill factor, panel efficiency, panel net energy, panel energy, power gain, and the system water consumption. The cooling system has the most considerable effect on PV panel maximum power, panel fill factor, panel efficiency, panel net energy, panel energy, panel power gain, and the system water consumption. In general, using the cooling system improves the PV panel performance through enhancing the PV panel efficiency, maximum panel power, panel fill factor, panel net energy, panel energy, and PV panel power gain. Keywords: Cooling system, cooling periods, water pump discharge, water type, time of day, efficiency, maximum power, fill factor, net energy, panel energy, PV panel power gain, and cooling system water consumption.

This thesis develops an analytical model of a small-scale solar central receiver power plant located at the California Polytechnic State University in San Luis Obispo, California at 35.28° N, 120.66° W. The model is used to analyze typical energy output at any time during the year. The power plant is designed to produce an output of 100 kW electrical power, and is supplemented by the combustion of natural gas. Methodologies for determining the proper size and layout of heliostats, optimal tower height, receiver size, and turbine engine selection are developed. In this specific design, solar shares of up to 73.2% and an annual average of 44% are possible through the use of a gas-solar hybrid microturbine engine. Larger solar shares are not possible due to the limited size of land (about 0.5 acres used for this project) which limits the number of possible heliostat installations.

The use of an attached sunspace is one of the most popular passive solar heating techniques. One of the main drawbacks of the sunspace is getting over heated by the sun energy during the hot season of the year. Even in northern climates overheating could be problematic and there is a considerable cooling demand. Shading is one of the most efficient and cost effective strategies to avoid overheating due to the high irradiation especially in the summer. Another strategy is using ventilation system to remove the excess heat inside the sunspace. However this rejected energy can be captured and stored for future energy demands of the sunspace itself or nearby buildings. Therefore the Solar blind system has been considered here for the shielding purpose in order to reduce the cooling demand. By considering the PV/T panels as the solar blind, the blocked solar energy will be collected and stored for covering part of the heating demand and the domestic hot water supplies of the adjacent building. From a modeling point of view, the sunspace can be considered as a small-scale closed greenhouse. In the closed greenhouse concept, available excess heat is indeed utilized in order to supply the heating demand of the greenhouse itself as well as neighboring buildings. The energy captured by PV/T collectors and the excess heat from the sunspace then will be stored in a thermal energy storage system to cover the daily and seasonal energy demand of the attached building. In the present study, a residential building with an attached sunspace with height, length and width of 3, 12 and 3.5 meters respectively has been assumed located in two different locations, Stockholm and Rome. Simulations have been run for the Solar blind system integrated with a short-term and a long-term TES systems during a year to investigate the influence of the sunspace equipped with a PV/T Solar blind on the thermal behavior of the adjacent building. The simulated results show that the Solar blind system can be an appropriate and effective solution for avoiding overheating problems in sunspace and simultaneously produce and store significant amount of thermal energy and electricity power which leads to saving considerable amount of money during a year.

Streszczenie:

The increasing global energy demand, which today is mainly supplied by energy sources with a fossil origin, is a severe threat to the environment and to the security of supply. In order to handle these problems, renewable energy sources are promoted globally as well as nationally in Sweden. Solar photovoltaic (PV) technology is one of the most mature and commercial renewable energy technologies and could play a vital role in phasing out fossil energy sources. In the emerging, promising concept of solar landfills, PV systems are installed on closed landfill sites in order to combine renewable electricity production with resource efficient use of land. In this study the legal, technical and financial aspects concerning a solar landfill project in a Swedish setting were investigated. Additionally, the potential of the concept on a regional level in Sweden was analysed. The methodology used in the study featured literature research, interviews, and a feasibility assessment of a solar landfill project on Visby landfill. Regarding the legal aspects linked to a solar landfill project, an inconsistency between Swedish municipalities concerning the need of a building permit for a ground mounted PV system was revealed in the study. While some municipalities demand a building permit, others do not. Additionally, the fact that a closed landfill usually is classified as an environmentally hazardous activity doesn’t result in any need for additional permissions for a PV system installation on a closed landfill. Therefore, such legal aspects are not likely to hinder a solar landfill project to any great extent. Considering the technical aspects, the choice of mounting system must be done carefully because of the special conditions which exist on a landfill site; such as ground penetration restrictions and risks of settlement. While a ballasted mounting system can avoid ground penetration, a driven pile mounting system generally features a lighter construction. Furthermore, a fixed tilt mounting system is preferred over a sun tracking mounting system due to the extra weight and sensitivity to settlement which comes with the latter choice. Regarding the choice of PV modules, thin film modules generally feature a lower weight and can therefore be advantageous in comparison with crystalline silicon modules. In the case of Visby landfill, where penetration was preferred to be avoided but where the risk of settlement was considered low, the PV system which was deemed most suitable for the site featured a ballasted fixed tilt mounting system with crystalline silicon PV modules. Considering the financial aspects, the study emphasises the importance of using the produced electricity to offset consumed electricity in order to enable a sound investment. This can be done by a wise choice of owning and financing structure where the produced electricity offsets consumed electricity for a large consumer, e.g. an industry or a grocery store, or for a number of residences in a community solar. The economic feasibility also heavily depends on the projects’ possibility to use policy incentives and tax exemptions. The feasibility assessment of Visby landfill showed that the most economically feasible investment was possible by founding a community solar which offsets the members’ consumed electricity. Such an investment would feature a 10 year payback time and an internal rate of return of 8.3 %. Finally, the potential of the solar landfill concept on a regional level was identified as significant. In a scenario where the PV system suggested for Visby landfill in the feasibility assessment is installed on all the suitable landfill sites on Gotland, the island has the possibility to produce 22 GWh of electricity from solar landfills, thereby meeting the regional energy goal set for 2020.

Streszczenie:

As California continues to integrate more renewable energy into its electrical system, the state has experienced a corresponding rise in photovoltaic system installations. PV arrays are a unique source of power generation in that they are affected by the location of the sun, shading, and temperature changes. These characteristics make solar one of the most highly variable forms of renewable energy. In order to improve solar power’s consistency, PV systems require a supplemental source of power. The primary focus of this paper is to determine if distributed energy storage systems can be used to reduce the effect of solar intermittency. This paper examines the test data and system specifications of an experimental DESS. The benefits of using a DESS in a PV system are further studied using computer simulation modeling. This paper also shows through computer simulations how a maximum power point tracker can increase a PV array’s power output. The results of this thesis demonstrate that DESS’s are capable of smoothing out highly variable load profiles caused by intermittent solar power.

Streszczenie:

Growing energy demands are expected to exceed the supply from current energy resources. Therefore, renewable energy and energy management systems will become more crucial for increasing supply and efficiency of energy usage. The novelty of this research is an energy management system (EMS) based on fuzzy logic for a solar house to ensure the maximum utilisation of renewable sources, protect components from being damaged due to overloading, and manage energy storage devices to increase stability in the power system. There is no published analysis of hybrid energy storage between battery and supercapacitor using fuzzy logic as EMS. The energy management system is implemented in a solar cabin system developed by IBC Solar to mimic a typical rural house. The solar cabin is equipped with solar photovoltaic panels, solar charger, battery and inverter. Supercapacitors and a custom made DC to DC converter were added to the system to support the batteries during high current load demand and manage energy flow. Three sets of experiments were conducted in the solar cabin system with the new energy management system. Power consumption usage of a typical rural household was studied to create two load profiles that were used as load for the experiments. The results show an efficiency of 95.9% by using the new energy management system and supercapacitors to the solar cabin, which is higher than recent research (95.2% and 84.4%). The result is on par with the Malaysian and International Standard in energy efficiency of around 95%. The energy management system controlled the charging and discharging of the battery and supercapacitor using fuzzy logic. The novelty of this thesis is use of supercapacitors to reduce stress on the battery and an energy management system to control and manage the system for efficient energy usage.

Streszczenie:

Hurricanes, floods, tornados and earthquakes create natural disasters that can destroy homes, businesses and the natural environment. Such disasters can happen with little or no warning, leaving hundreds or even thousands of people without medical services, potable water, sanitation, communications and electrical services for up to several weeks. The 2004 hurricane season ravaged the State of Florida, U.S.A., with four major hurricanes within a 6-week timeframe. Over nine million people evacuated their homes and damage to property was extensive. One proactive strategy to minimize this type of destruction and disruption to lives is the implementation of disaster-resistant buildings that are functional and operational. This approach uses the best energy-efficient buildings, fortified to the latest codes, and incorporates renewable energy systems. Businesses, government facilities and homes benefit from using photovoltaics to power critical items. This concept is a mitigation tool to reduce damage and cost of the destructive forces of hurricanes and other disasters. This past season’s experience showed that buildings designed and built to the latest standards with photovoltaic and solar thermal systems survived with little damage and continued to perform after the storm passed. Even following a disaster, energy conservation and use of renewables promotes energy assurance while allowing occupants to maintain some resemblance of a normal life.

Streszczenie:

Saudi Arabia’s Ministry of Energy has set ambitious renewable energy goals. Although the Kingdom’s current energy mix is dominated by conventional energy (>95%), it aims to draw 50% of its energy from renewable sources by 2030. Currently, the Kingdom enjoys very high solar photovoltaic potential, and it is also well positioned for wind generation. Thus, studying the reliability of highly renewable power systems and the impact of converting conventional generation to renewable energy is of paramount importance. The latter analysis is important because temperatures in the Kingdom are often high for a considerable portion of the year.

Streszczenie:

There is an innate and critical relationship between energy and weather, water, and climate. As the deployment of renewable energy, particularly wind and solar energy, increases, so too does dependence on weather and weather variability. Understanding, accounting for, and communicating weather and climate variables is therefore critical for the planning and optimization of the energy system. This puts increasing pressure on the scientific community, and particularly those working on the weather and climate aspects of renewables, to provide the right information to meet the key decision-making needs of the energy sector. This study is the second of two pilot projects on the provision of actionable information for decision-making through the tailored and targeted assessment of weather and climate science. This study confirmed that excellent progress is being made on a variety of fronts associated with renewable energy, which is critically important as we move to increase use of renewables. A consistent theme in the discussions under this study, however, is the need to bring together many disparate types of data, modeling, and analyses toward convergent tools that adequately address the complex interconnectedness of a national power system built on renewable sources. In many ways, the most significant finding of this study is the need for major convergence research efforts to build the necessary historical reanalysis datasets, integrated weather-energy forecast models, and policy and regulatory frameworks that can leverage current disciplinary research efforts.

Streszczenie:

There is a high degree of freedom and flexibility in the way to integrate renewable process heat in industrial processes. Nearly in every industrial or commercial application various heat sinks can be found, which are suitable to be supplied by renewable heat, e.g. from solar thermal, heat pumps, biomass or others. But in contrast to conventional fossil fuel powered heating systems, most renewable heating technologies are more sensitive to the requirements defined by the specific demand of the industrial company. Fossil fuel-based systems benefit from their indifference to process temperatures in terms of energy efficiency, their flexibility with respect to part-load as well as on-off operation, and the fuel as a (unlimited) chemical storage. In contrast, the required temperature and the temporal course of the heat demand over the year determine whether a certain regenerative heat generator is technically feasible at all or at least significantly influence parameters like efficiency or coverage rate.

This work performed measurement and verification of installed, operational solar wall systems at Fort Drum, NY, and Forbes Field, Air National Guard, Topeka, KS. Actual annual savings were compared estimated savings generated by a solar wall modeling tool (RETScreen). A comparison with the RETScreen modeling tool shows that the measured actively heated air provided by the solar wall provides 57% more heat than the RETScreen tool predicted, after accounting for boiler efficiency. The solar wall at Fort Drum yields a net savings of $851/yr, for a simple payback of 146 years and a SIR of 0.16. RETScreen models indicate that the solar wall system at Forbes Field, Kansas Air National Guard, Topeka, KS saves $9,350/yr, for a simple payback of 58.8 years and a SIR of 0.34. Although results showed that, due to low natural gas prices, the Fort Drum system was not economically viable, it was recommended that the system still be used to meet renewable energy and fossil fuel reduction goals. The current system becomes economical (SIR 1.00) at a natural gas rate of $16.00/MMBTU or $1.60 /therm.

Streszczenie:

Climate change, electrification to decarbonize the building sector, and the rise of renewable energy sources have made reducing the peak demand even more important than solely reducing the overall energy use. Solar radiation can have a significant impact on the energy use of buildings. However, previous studies on solar absorption in building envelopes have focused on cool roofs. Less effort has been made to evaluate the impact of solar radiation on heat loss and gain on walls. This paper summarizes a preliminary study to estimate the magnitude of the benefit low solar absorptance surfaces have on reducing peak demand and focuses on simulating a residential building with two types of U.S. code-compliant wall structures, a standard lightweight wall assembly, and a thermally massive mass timber wall, to evaluate the impact of the solar absorption coefficient of the surfaces on the heating and cooling energy use and peak demand. This effort aimed to identify whether a more comprehensive study should be undertaken to develop further the calculation tools previously developed for estimating the energy benefits for roofing systems in the U.S. by adding a similar tool for wall assemblies. Reducing the solar absorption coefficient from 0.9 to 0.3 resulted in up to 46% lower cooling demand and a 70% increase in heating demand depending on the climate. Peak demand reductions for heating and cooling energy were similar to the reduction in heating or cooling energy use. However, the annual energy use changed up to only 12% as lowering the solar absorption coefficient reduces cooling demand but increases heating demand. Whether the total impact overall is harmful or beneficial depends on the climate and type of structure. Additionally, a cool roof calculator was used to estimate the impact of solar radiation on roofs. The learning from this study is that the exterior color and the solar absorption coefficient should be chosen based on the climate to positively impact the energy use profile and peak demand.
