Space heating models for residential buildings and the influence of urban variables

Proceedings of the workshop Ispra, 12-14 September 2016. The aim of this second workshop was to discuss different approaches and methodologies to assess energy efficiency measures as well as energy usage and monitoring of energy flows at building, urban and regional level, representing an opportunity to share information, integrate stakeholders’ views and set the ground for mutual collaboration. Eleven invited leading organisations and EU projects were invited to take part in this workshop sending experts to present their projects and discuss how to assess synergies and how to arrive to a coherent approach for assessment of energy use in the built environment. Another twelve people from JRC, experts on energy efficiency, energy performance, geospatial data modelling and processing participated to the workshop. Guglielmina MUTANI presented an energy consumption model at urban scale that includes the impact of the urban context on buildings' energy consumption. The model is combining a top-down approach (statistical model at municipality scale) and a bottom-up approach (simplified energy-use model for space heating, hot water production and electrical use). It is based on previous research results on mapping energy consumption and renewables sources and uses the CitySim simulation tool for the description of the buildings (and of their energy needs). The urban context is modelled through an urban context factor. The tool has been applied to the city of Turin.
