Passivhaus – The Origin

It might surprise you to know that Passivhaus is not a latest trend in green building. IT’s been around for quite some time, since 1988, to be precise. However, green building, sustainability and the environmental awareness is a relatively new concept, which is why many are hearing about Passive Houses only lately.

The technique and principles actually emerged in Sweden in 1988 and the first ‘passive house’ was built in Germany 2 years later and 6 years after that, the Passivahus-Institut was founded in Germany. After that, over 15,000 houses have been built, largely in Europe and particularly in Scandinavia using the passivhaus technique. Closer home, the first passive house was constructed in Illinois in 2003. In the US, passivhaus is looked at as a relatively new concept, but one that architects and builders will be quick to embrace, given its potential and possibilities.

The first principles of passivhaus required homes to have a space heating requirement which was 90% less than other houses. To this, other engineers, builders, and architects added their own innovations which made achieving this standard easier and economical. Eventually, building products like construction materials, window and door frames, glass came to be designed specifically for passive houses. Of special mention is a software program called the Passivhaus Planning Package developed and sold by the Passivhaus-Institut that helps architects design and create passive houses. The European Union in 2008 called for a binding requirement that from 2011, all houses built requiring heating and cooling should be built by the passivhaus standard.
