Due to its importance, it is a key arm of Sustainable Energy for All (SE4ALL). In buildings, energy efficiency can best be achieved by the use of less energy in the daily operation of buildings. This research analysed the suns potential in temperate buildings as a tool to lessen energy use. After analysing the weather data and buildings of the case study area, buildings oriented to the south were the best option for Nottingham. When the building fabric was modified for more heat gains, less energy was needed to heat up the buildings. Roofs of buildings were also oriented to the south and this received a lot of solar radiation. An active solar system when placed on the roof generated a yearly total of 17,486kWh. With the average yearly energy demand of buildings in UK around 18,000kWh, this energy produce can be sustainable to an average home in the UK. Even though financial analysis should be done to conclude on profit, this gives a good sign. This paper therefore proved the relevance of the sun in the design and construction of temperate buildings for energy efficiency and this should be encouraged in all temperate regions For Referring this Paper: Gyimah K.
