What does the Energy Saving Ordinance say (EnEV)?

The Energy Saving Ordinance (EnEV) is part of the German economic administrative law. In it, the legislator, on the legal basis of the authorization by the Energy Saving Act (EnEG), prescribes standard constructional requirements for the efficient operating energy demand of their building or construction project. It applies to residential buildings, office buildings and certain operational buildings.

The abbreviation EnEV refers to the Energy Saving Ordinance issued by the Federal Government with the aim of reducing the energy requirements of buildings to protect the climate. In the EnEV is regulated, which energy standard a house, or parts of the house after a renovation must reach, or which requirements are made on new buildings. The EnEV is reformulated and tightened again and again over the years so that by the year 2050 an almost climate-neutral building stock can be realised. The current EnEV 2014 was issued on 1 May 2014. Since non-compliance with the regulation leads to heavy fines, homeowners should work with an energy consultant and demand proof from the tradesman that the work on the house has fulfilled the requirements of the EnEV. An important measure for compliance with the EnEV is the installation of suitable windows and doors that do not exceed a certain U-value.

Final energy consumption
The final energy consumption is the sum of the energy consumption for all energy sources used during one year per object. The final energy comprises the last stage in the trade. Final energy is the energy available for consumption, such as electricity, heating oil, gas, wood, other renewable energies, other non-renewable energies.

Welcome to the ENERsign® U-Value window configurator:

The U-value window is also called heat transfer coefficient and according to the standard DIN EN 10077 it indicates the amount of thermal energy lost through a window to the outside.

The U-value window is calculated using the formula W/(m²K), i.e. watts per square metre and Kelvin. This value refers to the entire window and defines the amount of energy per unit of time that flows through an area of one square meter when the air temperature on both sides differs by one Kelvin. The lower this value is, the less energy or heat the window emits.
