Energy consumption and urban texture

The effects of urban texture on building energy consumption has been experimented through this research . According to Senseable city lab research the analysis of digital elevation models (DEMs)—raster models of cities which have proven to be very effective in the urban context has become a base study model for the initial steps towards form generation. What has been done through thier research is,introducing different algorithms, including the calculation of the urban surface-to-volume ratio and the identification of all building areas that are within 6 m from a fac¸ade (passive areas). An established computer model to calculate energy consumption in buildings, the LT model, is coupled with the analysis of DEMs, providing energy simulations over extensive urban areas. Results for the three case study cities of London, Toulouse and Berlin are presented and discussed. What has been done so far in this research is taking their methodology to create an energy efficient geometry by considering its surface to volume ration relationship.
