| Title | Net-Zero Energy Buildings: Global and Regional Perspectives |
| Summary | Net zero-energy building (NZEB) is usually understood as a highly energy efficient building, in which the remaining (low) energy demand is supplied with renewable energy. Net-zero energy/emission mandates have been mushrooming worldwide, while the expert community remains divided or at least cautious with regard to the feasibility or environmental desirability of forcing such construction/retrofit in certain cases. The aim of this research is to contribute to the debate around the NZEB concept from global and regional perspectives through analyzing the role of solar energy produced on site together with energy efficiency measures in meeting building energy demand. In order to achieve this goal a special model – BISE model – has been developed, which allows for estimating solar thermal and electric energy output from advanced building-integrated hybrid technologies taking into account various geographical, architectural, morphological and climatic parameters. This model is based on a novel methodology combining bottom-up energy modelling with geospatial analysis and outstanding visualisation techniques. A comprehensive bottom-up energy model, developed by Centre for Climate Change and Sustainable Energy Policy, has been used in order to estimate global and regional building energy demand with certain data inputs from BUENAS model (particularly for energy use by appliances and lighting). Combining the results on energy demand and potential solar energy supply provides a valuable scientific insight on the locations and building types where it is feasible to achieve the net-zero level of energy performance through application of solar technologies. The results show that realization of technical potential for state-of-the-art solar energy technologies in the building sector together with energy efficiency improvement will significantly reduce global and regional energy use and will allow for achieving net-zero energy goals in a number of locations and building types. |
