Urban Mixed Use and its Impact on Energy Performance of Micro Gird System

Urban mixed use as one of the key urban morphological factors, has the potential to impact the urban energy supply and demand, including not only transportation energy but also building energy. This paper is focusing on mix-used urban functions and building energy performance, such as residential building, commercial building, office and so on, to explore the correlation between them by computing simulation of simplified models. First of all, the district energy performance with different cover ratios, but the same mix-used ratio is examined. Then aiming for achieving stable energy profile, the energy fluctuation with different mix-used ratio is evaluated and analyzed based on the same physical model. Solar potential is also taken into consideration during the process. Finally, this paper concludes that urban mixed use can impact the energy efficiency in certain degrees, meanwhile its potential to guide urban design is discussed.
