  • What does the term building envelope mean?
    In energy-saving houses, the entire building envelope is excellently insulated.

    The building envelope consists of all components that separate the interior from the exterior. The interior should have a comfortable climate - the weather determines the exterior.
  • What does the term edge seal mean?
    In insulating glass, the edge seal connects the individual panes in the edge area. It consists of a special spacer and adhesives or sealants, which are normally applied in two stages. The spacer contains a drying agent to dehumidify the volume of air or gas enclosed in the hermetically sealed space between the panes and to prevent misting of the inner surfaces of the panes.
  • What does the term "embrasure" mean?
    Wall rebate from the window to the inner or outer surface of the wall.
  • What does the energy balance say?
    Sum of all energy gains and losses of a building.
  • How do you define energy efficiency?
    Efficiency is the ratio of effort to benefit. Energy efficiency indicates how effectively an energy conversion chain or device converts the energy put into it. A key figure for energy efficiency is the efficiency factor η. It indicates the ratio of usable energy to energy expended. Its value lies between 0 and 100 %.
  • What is an Energy Performance Certificate?
    The energy performance certificate is a document that evaluates a building in terms of energy.
  • What's behind the term energy reference surface?
    The energy reference area is the sum of all above and below ground gross floor areas for whose use heating or air conditioning is necessary. It is calculated from the external dimensions of a building, i.e. including limiting walls and parapets.

    Sum of all above and below ground floor areas for the use of which heating or air conditioning is necessary.
  • 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.
  • What is an EnEV-House?
    Building that meets the statutory minimum requirements in accordance with the current Energy Saving Ordinance (EnEV).
  • What does EPDM mean?
    EPDM is the abbreviation for ethylene-propylene-diene and refers to a synthetically produced rubber. EPDM has a very high resistance to heat, water, steam, solvents, ozone and solar radiation and is therefore ideal for sealing.
  • What is meant by equity?
    All financial resources available to a builder and borrower for financing in addition to the loan itself. These include cash, fixed-term deposits, bank and savings deposits and the proceeds from the sale of securities and shares. Furthermore, the building land owned, paid building materials and architects' services as well as own work to be performed.
  • What are external blinds?
    External venetian blinds are an external sun protection product, which serve to protect against light and privacy and are more effective in preventing heat build-up in summer. The slats of the external venetian blinds are made of roll-formed aluminium. The most common slat widths are 60 mm, 80 mm, 90 mm and 100 mm. Venetian blinds are available with perforated or partially perforated slats, colours, patterns, sizes and shapes. Even triangular or trapezoidal systems are feasible within a certain range.
  • What is an extract from the land register?
    Complete copy of all existing land register entries for a property. To be inspected in case of "justified" interest (e.g. intention to purchase).
  • What is a KfW Efficiency House?
    The term "KfW Efficiency House" is a term developed by the German Energy Agency GmbH (dena) together with the Federal Ministry of Transport, Building and Urban Affairs (BMVBS) and the KfW. KfW uses the efficiency house in its promotional programmes. The figure after the term KfW Efficiency House indicates how high the annual primary energy requirement (Qp) may be in relation (%) to a comparable new building according to the specifications of the German Energy Saving Ordinance (EnEV).

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.
