The large-scale development of passive low-energy buildings, the path to achieving high-efficiency goals
Aug 11,2022
The large-scale development of passive low-energy buildings has shifted the path to achieving high-efficiency goals from individual buildings to districts/urban areas; from improving the energy efficiency and utilization of individual buildings to overall energy planning at the district/urban area level. Implementing high-efficiency buildings at the district/urban area scale, based on passive low-energy building technologies, optimizes the mix of building types within the area and the staggered peak energy consumption times to achieve overall load leveling in the region, thereby further suppressing regional energy supply requirements. At the same time, it integrates the application of renewable energy sources (photovoltaic, solar thermal, geothermal, wind power, etc.) located in different spaces, and uses low-grade energy for direct heating and cooling/pre-heating and pre-cooling, as well as energy storage power stations and thermal/cold storage systems to provide energy flexibility, ultimately achieving energy production, storage, and consumption balance in the district/urban area.
