Designing buildings with both low energy demand and on-site energy production is one of the main strategies put forth in order to achieve carbon neutrality by 2050. Computers help us to simulate and estimate efficient scenarios according to different parameters such as, distribution, urban configuration, or even time, This project collects a numbers of projects exploring radiation estimations in different contexts (Space) and historic moments (Time). “Time”: we present simulations and analysis based on a digital model of a case-building, using different weather files, representing data for three alternative future climate change (CC) scenarios. “Space”, we use a parametric model to estimate the PV solar harvesting potential of rapid changing metropolitan areas like the pirate-origin neighbourhoods in Bogota.
