KlimaHaus (Italian: CasaClima , English: ClimateHouse ) is a certification system for energy-efficient building in the autonomous province of Bolzano - South Tyrol . It was founded in 2002, modeled on the EU - Buildings Directive 2002/91 / EC, the first building label in Italy introduced and is a standard for sustainable, resource-efficient and sustainable building .

In the autonomous province of Bolzano - South Tyrol, the KlimaHaus building standard for low-energy houses is required by law. In 2005, the minimum standard of energy efficiency for the building envelope was made mandatory with Class C for new buildings. As of June 13, 2011, the standard KlimaHaus B (so-called 5 liter house) was mandatory as the minimum energy efficiency class for new buildings. From January 1, 2017, the South Tyrolean provincial government raised the minimum standard for new residential buildings to KlimaHaus-Standard A (so-called 3 liter house).

history

KlimaHaus was developed in the years 2000 to 2002 in the Office for Air and Noise of the Autonomous Province of Bolzano - South Tyrol under the leadership of Office Director N. Lantschner.

In November 2005 the United Nations invited the “KlimaHaus” project to the 11th World Climate Conference in Montreal. KlimaHaus was selected from 21 projects as an example of concrete and sustainable climate protection.

KlimaHaus is in a continuous expansion. In mid-2011 there were 3,200 certified KlimaHaus all over Italy.

The KlimaHaus Agency

The KlimaHaus Agency Bolzano was founded in 2006. In 2014 the KlimaHaus Agentur GmbH, an in-house company of the Province of South Tyrol, was transferred to the Agency for Energy South Tyrol - KlimaHaus, an auxiliary body of the Autonomous Province of Bolzano - South Tyrol.

The KlimaHaus certification is the official confirmation of the energy requirements of a building and is carried out exclusively by the KlimaHaus Agency. This is not involved in the construction process, but works with external KlimaHaus auditors. The auditors carry out controls according to standardized procedures.

The core work areas of the KlimaHaus Agency are to inform and raise public awareness of all aspects of building and energy. The agency offers courses for planners, craftsmen and builders.

KlimaHaus classes

Depending on the heating energy requirement, buildings are divided into the following classes:

  • KlimaHaus Gold: heating energy requirement below 10 kWh / (m² · a)
  • KlimaHaus A: heating energy requirement below 30 kWh / (m² · a)
  • KlimaHaus B: heating energy requirement below 50 kWh / (m² · a)

Certification

The certification of the KlimaHaus Agency classifies the buildings according to the energy efficiency of the building envelope. Energy efficiency is the basis for defining the KlimaHaus classes.

The certification process is specified in the technical KlimaHaus guidelines. This defines precise rules for calculating the heated building envelope and the heated volume as well as the avoidance of thermal bridges, summer thermal insulation and much more.

Since March 1, 2010, an air tightness test (Blower Door Test) has been mandatory for new residential buildings and offices. The classification into energy requirement classes takes place after examination of the construction or completion of the project. The KlimaHaus Agency carries out on-site inspections and checks on the construction sites. After a final inspection, the KlimaHaus energy pass is issued and the sticker is handed over.

The KlimaHaus energy pass

The energy certificate for a building provides information about the energy efficiency of a building and is an aid to estimating the energy costs. The KlimaHaus energy pass can be applied for for all types of building use.

The energy pass provides information about:

  • The energy efficiency of the building envelope: It reflects the quality of the building's energy savings.
  • The overall energy efficiency: It describes the energetic quality of the building envelope and the built-in building technology.
  • The sustainability of the building: It evaluates the materials and systems used from an ecological point of view.

KlimaHaus nature

In addition to the energy requirement for living, KlimaHaus nature also quantitatively assesses the environmental compatibility and the energy consumption for building materials.

An application for a KlimaHaus nature certification requires the following criteria:

  • Heating requirement ≤ 50 kW / m²a
  • CO 2 emissions ≤ 20 kg / m²a
  • Building materials: KlimaHaus nature rating <200 points (Pro KlimaHaus 2009)
  • Resources:
- No tropical wood or wood from protected areas
- Water : technical measures to reduce water consumption
- Reduction of soil sealing
- Use of materials that comply with the limit values ​​of the KlimaHaus nature technical guideline for emissions (e.g. VOC , formaldehyde )

KlimaHaus nature evaluates the building according to three indicators for environmental pollution:

  • Primary energy demand from non-renewable resources PEI ne [MJ]
  • Acidification potential AP [kg CO 2 equivalent]
  • Global warming potential GWP [kg CO 2 equivalent]

In addition to KlimaHaus nature , there are other certification systems for energy-efficient and sustainable buildings: KlimaHotel, KlimaHaus Habitat (housing developments), KlimaHaus Wine (wineries), KlimaHaus Work & Life (multifunctional buildings) and KlimaHaus MobileHome (mobile homes).
