DOMUSGAIA PASSIVE X-LAM HOUSES:
A Building Envelope, result of a skillful execution
All the components of the outside part of the building are designed, insulated and constructed with such precision and without thermal bridges, that heat dispersion during wintertime is close to zero and compensated by the sunlight coming through the windows and radiation produced by the persons themselves and by the electrical appliances in the house.
The orientation of the house and the disposition of the glazings are very important to maximize free sunlight contribution.
Choice of Plants
The passive house philosophy doesn’t include fossil fuel for heating but plants based as much as possible on renewable energy. The system mostly used includes a heat pump for domestic water supply and for regulating air temperature.
For air conditioning in summertime (if necessary) you can fully use controlled mechanical ventilation with geothermal vertical or horizontal cooling to exploit the constant sub soil temperature. This allows removal of unaesthetic split air conditioners.
The ventilation system is another important detail : besides contributing to reducing energy charges, this plant continuously introduces fresh air at a constant temperature, with healthy controlled humidity, free from impurities, and perfectly hygienic and you enjoy a outstanding living comfort.
Warm in Winter, Fresh in Summertime
The DomusGaia passive houses with x-lam are especially suitable to our climatic conditions, because they perfectly match winter and summer behaviors together, because of their mass walls with wood that has a high specific heat capacity.
In practice, during the summer you need a lot of energy to increase temperature, while during the winter a lot of energy is stored free and released constantly and in a sustainable way.
Why choose a Passive House
There are many reasons why a customer should choose a Passive House:
1. Starting from 2021, all news constructions will have to be “nearly zero energy buildings”(NZEB)
2. Make a good use of your own financial resources by building a house which won’t decrease in value in time
3. High standards of living comfort
4. No more wintertime “worries”, becoming indoor, short and nice
5. Lively summers cooling your home with low energy consumption, self-produced if photovoltaic
6. More efficiency of the building performances with less systems
Let’s talk about costs
A passive house compared to a traditional building, costs around 7-10% more. But an experienced designer and builder will be able to minimize costs, because many of the measures they take, that influence the final result are “free” and they are the result of a careful design and precise performance.
