The 2014 German Energy Saving Ordinance (EnEV 2014): Stricter Requirements for Energy Efficiency

  • Kategorie: Industry news, General, Products

27. June 2014 | How to comply while reducing heating costs – with KRONOPLY insulation

An update of the German Energy Saving Ordinance (EnEV) entered into force on May 1st of this year. It imposes stricter requirements on the permitted energy consumption and thermal insulation of new buildings constructed from 2016.

From 2021 at the latest, Europe-wide rules will require all new buildings to be erected in compliance with a “nearly zero-energy building” standard. By introducing the new EnEV with its tightened stipulations, the German government is taking another step along that path. The big goal is for all of the country’s buildings to be nearly climate-neutral by the year 2050.

The new EnEV requires the following of all buildings erected from 1 January 2016:

  1. Lower consumption of primary energy, by an average of 25 percent of the current ceiling.
  2. The thermal insulation used on the building envelope must be 20 percent more effective as measured by its overall heat transfer coefficient. KRONOPLY’s extensive portfolio includes insulation products, environmentally friendly OSB boards and versatile MDF boards for easily and effectively complying with this requirement. KRONOPLY safe, for example, featuring a high bulk density of 85 kg/m³ and optimised lambda values, was specifically developed to enable effective, thermal-bridge-free insulation of roofs and walls. It is particularly ideal for use as on-roof or on-rafters insulation. Because its lamination has pre-attached squares of double-sided adhesive tape, KRONOPLY safe very practically combines three steps in one: installation of the insulation, creation of water channels and sealing.

EnEV 2014 also stipulates the following for already-standing buildings:

  1. It’s now mandatory to insulate the ceilings of heated top-storey rooms if the roof isn’t appropriately insulated. Because warm air rises, poorly insulated buildings lose large amounts of heat in this way. Well-insulated ceilings greatly reduce heat loss, which in turn noticeably slashes heating costs. The overall heat transfer coefficient, or u-value, may not exceed 0.24 W/m²K. The wood-fibre insulation KRONOPLY uni, which was specifically developed for insulating ceilings under screed and top-storey ceilings and for use as on-rafters insulation, scores points with a very good thermal conductivity value, a considerable heat storage capacity and optimal compression strength.
  2. From 2015, old oil- and gas-fired boilers must be replaced if they have been in operation for more than 30 years.

The requirements for providing information on buildings’ energy consumption have also been tightened. Now these data must be more openly communicated to buyers or tenants.

A two-year deadline has been set for meeting the stricter rules. Owners of buildings that are not compliant by May 2016 will be fined.

Book recommendation: Baustellenhandbuch für die Ausführung nach ENEV 2014 (Forum Verlag Herkert). This pocket-sized handbook is a practical source of information and details for complying with the EnEV, including checklists and tables – a valuable companion at construction sites.

The lamination makes KRONOPLY safe the ideal on-rafters insulation. KRONOPLY flex is effective, healthy insulation for walls, ceilings and roofs.
