The Green-Push Goes Home with KlimaHaus

KlimaHaus is the new way to make home-living sustainable for the environment and for your wallet.

Air Pollution in Delhi
Air pollution - both indoor and outdoor - has climbed up the urban agenda. According to the World Health organisation, fine particles in the air contribute to 7 million premature deaths globally per annum, often caused by heart disease or lung cancer. And the list goes on. Fine particulate pollution also appears to increase the incidence of dementia as well as asthma. Pollution inevitably has an impact on people’s life in cities. What if it would be possible to reduce levels of dirtiness in the atmosphere around cities? What if there was a tangible starting point?
A solution is KlimaHaus, an energy certificate born in Bolzano (Italy), which pushes new construction methods to sensibly decrease the level of pollution due to heating or cooling in buildings.

KlimaHaus’ goal: new with old

KlimaHaus aims at providing directories in order to construct buildings with the highest possible energy efficiency. The company provides for three certificates to identify the degree of consumption: Gold (attributed to the best performing buildings), B and C (for those building which have been renewed). A construction which receives a KlimaHaus certificate may consume less than 10 kWh/ m2 per annum, i.e. around 12 times less than an average building. But how is it possible to receive such recognition? The answer lies in combing new technologies with old building techniques.
To start with, insulation represents the pillar of an efficient house. In fact, it allows the outside temperature not to influence the indoor one and vice versa. The highest level of insulation is obtained through a compact shape, a.k.a. a building with a quadratic structure thus reducing thermal bridges, and external wall insulation. Moreover, windows must respect strict standards to reduce heat transmission.

KlimaHaus requires the use of solar panels for the production of electricity and for heating water. This last function is also objective of the geothermal system which must be built where the soil formation allows it. Furthermore, floor heating is requested as it allows to heat up a building with lower temperatures, hence lower consumption of energy, due to the fact that this system reaches all points of a room uniformly. Finally, the company suggests building an air recirculation system in order to improve the quality of air and to guarantee homogenous temperatures throughout the entire building.

Is KlimaHaus the real solution we are seeking?

KlimaHaus is the perfect starting point in the journey towards less polluted cities and urban environments. Not only it guarantees high quality of living, but it also assures low consumption. This means lower costs for home owners and firms and lower damage for the environment. It combines sustainability with high standards. However, there is another solution which may dramatically change the way we think urban development: Passivhaus Institut. Which of the two will emerge as the future building technique?
