lågenergibyggnader
Lågenergibyggnader, commonly translated as low-energy buildings, are structures designed to use only a small amount of energy for heating, cooling, hot water, and electricity relative to conventional buildings. The term is widely used in Nordic countries but is applied internationally with varying thresholds and definitions. In practice, lågenergibyggnader are defined by specific energy performance targets, often expressed as annual energy use per square meter (kWh/m²/year) or as primary energy consumption, and they are achieved through a combination of efficient envelope performance, efficient systems, and sometimes on-site renewable energy.
Key design principles include a highly insulated and airtight building envelope with minimized thermal bridges, high-performance
Standards and frameworks used to define or certify lågenergibyggnader include the Nearly Zero-Energy Building (NZEB) standard
Benefits of adopting low-energy buildings include reduced energy costs, lower greenhouse gas emissions, and improved indoor
