Heat emissions from buildings in many cities play an important role for the urban surface energy balance (USEB) and the urban micro-climate. Heat generated indoors from human activities (e.g., use of electrical appliances, space heating, metabolic rate) is conducted through the building fabric and affects the USEB through long-wave radiation and turbulent sensible heat flux. The radiative and thermal properties of materials used in the building’s structural components (e.g., external walls, roof, windows) determine the storage of heat in the building volume and therefore the rate and timing of heat exchange between indoor and outdoor environments. This also affects the overall indoor thermal comfort.We use a building energy model (STEBBS – Simplified Thermal Energy Balance for Buildings Scheme) to simulate and compare the anthropogenic heat flux from residential buildings in the city centres of London, UK, and Berlin, Germany, in different seasons. Occupancy schedules and timings of indoor heat gains for STEBBS can be determined from the agent-based model DAVE (Dynamic Anthropogenic actiVities and feedback to Emissions; McGrory et al. – this meeting). Both cities feature a diverse set of building types (determined by common morphological attributes) and a range of typical construction types that are derived from information on building age bands, building regulations and building typologies (EPISCOPE, TABULA).
