NiedrigenergieStandards

NiedrigenergieStandards, often translated as low-energy standards or nearly zero-energy standards, are building regulations or certification schemes that aim to significantly reduce the energy consumption of new buildings. The primary goal is to minimize the amount of energy required for heating, cooling, ventilation, and hot water while maintaining a comfortable indoor environment. These standards typically involve a combination of high levels of insulation, airtight construction, high-performance windows and doors, and energy-efficient mechanical systems.

The concept originated in Europe, with the European Union's Energy Performance of Buildings Directive (EPBD) being a key driver for the widespread adoption of these standards. The EPBD mandates that all new buildings constructed after a certain date must be nearly zero-energy buildings (NZEB). This means their energy performance is very high and the nearly zero or very low amount of energy required is covered, to a significant extent, by energy from renewable sources, including energy generated on-site or nearby.

Implementing NiedrigenergieStandards involves a holistic approach to building design and construction. This includes careful consideration of the building's orientation, shading, and natural ventilation potential. Advanced building physics principles are applied to prevent thermal bridges and ensure a well-sealed building envelope. The selection of energy-efficient appliances and lighting also plays a crucial role. While these standards may require a higher initial investment, they aim to deliver long-term savings through reduced energy bills and increased property value, as well as contributing to environmental protection by lowering greenhouse gas emissions.
