Abstract

With increasing population and urbanization, cities are expected to draw energy demands from diverse sources, especially local on-site generation. For energy-efficient urban design and planning, understanding the energy demand and consumption at the city scale is essential. Therefore, the use of alternate means of energy generation and advanced technologies such as photovoltaic (PV) is pertinent. This chapter uses a simplified methodology for the quantification of consumption and a possible supply of energy demands of an urban district by classifying them into archetypes, a bottom-up urban energy modelling technique. Climate data, land use, building use, height, floor area, occupancy, the assumption on HVAC-dependent areas, wall-to-window ratio (WWR), U-value of materials, roof area, surface areas respective to cardinal orientations, and annual solar radiation are used for classification of archetypes, energy quantification and PV potentials. Based on this classification, 917 buildings in the study area are classified into 14 archetypes with eight different residential and two different commercial, mixed-use ...
