Abstract	The challenges of warming urban climate on building energy needs for space conditioning are discussed by assessing the impact of intra-urban microclimatic changes, also called as urban heat island (UHI). This paper presents the results of a simulation study on the energy consumption for heating and cooling of a small-office building within intra-urban microclimatic conditions of the Chicago metropolitan area. The urban development influences: land-use land-cover and anthropogenic heat by buildings, industry, and transportation and the lake effect that modify climatic conditions are reflected in the weather files selected from five locations in the study area. The study simulated a small-office building per ASHRAE Standard 90.1-2013 with typical construction, heat gains and operational patterns with a whole building energy simulation program eQuest 3.65 for selected locations. The results confirm that heating load decreases, and cooling load and overheating hours increase as the office location moves from rural (less developed) to urban (developed) sites however, these changes are influenced by the distance from the downtown and the Lake Michigan. It is shown that prominent intra-urban climatic variations are an important factor affecting energy performance. The paper presents detailed results of the typical small-office placed within intra-urban climatic zones of the metropolitan area, arguing the necessity to consider using weather files based on UHI for the design of current buildings to safeguard their efficiency in the future.
