Abstract
Installing photovoltaic (PV) panels on the roofs of homes may reduce dependence on the electrical grid and lead to net-zero energy production. Climate patterns and a building’s structural system can significantly affect how much energy the structure uses. This investigation is aimed to focus on the shading effect of solar panels on the uninsulated roof of a residential building to investigate the output of combining architectural buildings with renewable energy systems. The PV system was modelled as a shading device using building simulation software (Design Builder) to calculate the monthly reduction and increase in heating and cooling loads for the rooftop in a humid subtropical climate zone. The results showed that the cooling loads were decreased by 290 kWh/year (almost 5%) and heating by almost 30 kWh/year. The findings showed the importance of renewable energy in tackling climate change and reducing the housing energy requirements for sustainable development.
