Abstract
In urban scale, solar energy utilization potential is closely related to residential density. Taking Xining City as an example, this paper explored how density of urban residential area affects solar energy utilization potential of urban housing. By changing density related design variables , including building layout, density rate, floor-site area ratio and the number of floors, 36 general models of residential areas with low, medium and high density are Abstracted. The results show that solar energy utilization potential of buildings varies greatly with different density related design variables. Comparison of a number of different scenarios reveals how density related variables affect solar energy utilization potential, based on which suggestions for optimization of solar energy potential for urban residential areas in their initial planning and design stages are proposed.
Highlights
Cities are home to more than half of population in the word, consuming most of the energy and resources
Juan José et al [3]discussed the relationship between urban morphology and urban solar energy collection. It analyzes the different possibilities of urban form in London and tests the variables of urban form in order to increase the solar energy potential of the region
Christina Chatzipoulka et al [4]discussed the relationship between design variables and the solar energy utilization potential of the building facade and the ground
Summary
Cities are home to more than half of population in the word, consuming most of the energy and resources. Juan José et al [3]discussed the relationship between urban morphology and urban solar energy collection. It analyzes the different possibilities of urban form in London and tests the variables of urban form in order to increase the solar energy potential of the region. Christina Chatzipoulka et al [4]discussed the relationship between design variables and the solar energy utilization potential of the building facade and the ground. Itis based on morphological and solar energy analysis of 24 urban forms in London, These studies range from building and community to urban and regional scale. The objectives of the study are: (1) Quantify the effectiveness of the solar energy utilization. (2) Comparing the effectiveness of solar energy utilization at different building densities
