    Regulated energy loads of buildings are typically explored at the scale of individual buildings, often in isolated (and idealized) circumstances. By comparison, little research currently exists on the performance of building groups that accounts for the interactions between buildings. Consequently, the energy efficiency (or penalty) of different urban configurations (such as a city street) is overlooked. The present paper examines the energy demand of a city street in London, UK, which is comprised of typical office buildings with internal energy gains associated with daytime occupancy. Simulations are performed for office buildings placed in urban canyons that are defined by the ratio of building height (H) to street width (W). The results show the annual energy demand is dominated by the cooling load, which can be significantly reduced through street design that provides shading by increasing H/W. However, the ‘best’ street design for modern office buildings may be incompatible with that for residences or, for that matter, outdoor climates.
