Add to calendar Buildings represent a third of the world's energy demand. In Brazil, energy consumption in buildings accounted for 15% of total energy consumption, 46% of electricity consumption and almost 90% of LPG consumption in 2019 (EPE, 2020). At the same time, future scenarios project an increase in the share of electricity consumption in buildings, with important impacts on the electricity system. Improving the efficiency and sustainability of new and existing buildings is critical to ensuring that buildings meet people’s needs while contributing to clean energy transitions. These improvements can generate local jobs, improve the healthfulness of buildings, save on energy bills, and provide many more important benefits.
