Passive Homes

We love wood and the planet that creates it. For us, passive houses are a beautiful dream turned into reality.

Passive buildings vs zero-energy buildings

The passive house – the way Passivhaus Institut defines it – is an extremely energy efficient house but it is different from the zero-energy building in that it still requires a small amount of energy to maintain interior comfort, even though very small. The term “passive” is applicable to both individual and collective homes or to industrial and commercial buildings. In building a passive house, every element plays a role in reducing the energy consumption and minimizing the loss of air or of energy.

The wooden passive house - comfort guaranteed

Why is a wooden structure an advantage when building a passive house? Wood mixes the ability to absorb the heat and to retain it with a large number of extremely important attributes such as impermeability, structural integrity and the quality of the finish.

Starting from a good understanding of the terrain on which the house is about to be built, the energy efficiency of the new building is due equally to positioning, the judicious use of the resources during the building process, the correct placement of the thermal masses, the placement of the rooms, doors, windows, the shadow sources, etc.

The passive house standard requires at least the following performances:

A maximum of 10 W/sqm constant thermic requirement

A maximum of 42 kWh/sqm energy required yearly.

A maximum of 15kWh/sqm required yearly for heating up space

Without respecting the parameters above, a building is no longer certifiably passive.

Dimmer - a completely Passivhaus Institut-certified team, from design to installation

The European 2010/31/UE of the European Parliament and the European Council from May 19 2010 regarding the energetic performance of the buildings, foresees the rise of efficiency of the new buildings and establishes that all new buildings should be energy-efficient (“nearly zero-energy”) by the end of 2020, and the public ones until 2016.

According to IPHA (The International Passive House Association), only approximately 60.000 houses in the world are built according to these standards, even though a considerable lower is certified in this respect. Both the engineers and the assembly team from Dimmer are PHI (Passive House Institute), for the knowledge in projecting the buildings while respecting the passive house standards. One of the most recent passive houses projects that Dimmer took part in is #casabuhnici
