Building form effects on energy efficient heat pump application for different climatic zones

Energy efficiency in built environment remains the most important sustainable building issue, not only because of its environmental impacts but also the probability of significantly higher future energy costs. Optimized passive design integrated renewable energy systems can greatly reduce the energy consumption in buildings. In this study; in order to provide energy conservation and climatic comfort in buildings, an approach which aims to control the energy consumption of heat pumps in different climatic zones by controlling decisions related to building design parameters has been developed. For this purpose, four different building forms, namely square, rectangular, L-shaped and H-shaped which have the same foor area, volume and optical and thermophysical properties of building envelope are examined in temperate, hot and cold zones of Turkey by using a building simulation program, e-QUEST. Annual total heating and cooling energy consumptions of vertical loop ground and air source heat pump systems are calculated for every building form in temperate-dry, hot and dry and cold climatic zones.
