Spatial Evaluation of Energy Performance at Neighborhood Scale Case study: Sanandaj city

Abstract

Climate change has become a challenge with adverse impacts on the Earth. Reducing the use of fossil fuel is a primary step to solve environmental problems. As the population continues to rise, to meet the growing demand for construction with a large share in energy Consumption, Efforts to make the built environment more energy efficient is crucial. The main objective of this research is to evaluates the relationship between urban form and the energy performance of neighborhoods, focusing on their energy demand, through case studies of Ghatarchyan and Mobarakabad neighborhoods in Sanandaj city. The forms of these neighborhoods were measured using spatial metrics (physical and climatic criteria). For analysis and evaluation, ECOTECT, GIS software and ANP method have been used. The results of research indicate a negative correlation between spatial metrics and building energy performance. Therefore, if spatial metrics amount of each neighborhood increases, neighborhood energy demand will decrease. Moreover, the result can form a basis for urban design recommendations to achieve an energy efficient urban development through spatial design.
