Passive House For All!

Passive House For All!

Submission ID:



We face currently two major needs in the building sector in Portugal in particular and worlwide in general.

First there is a need to reduce CO2 emissions associated with the use of buildings. Second there is a need to improve the quality of the park built in Portugal.

The quality of the buildings we use is generally poor, characterized by the following:
- poor indoor air quality;
- insufficient levels of thermal comfort exposing the existing energy poverty;
- indoor environments with high exposure to humidity and mold;
- insufficient levels of acoustic comfort revealing a high exposure to outside noise;

The link between the indoor environments we use and our health is clearly identified.


The solution is to realize the transition of the existing building stock to the Passive House performance levels and permanently assuring: indoor air quality, thermal comfort, absence of pathologies, acoustic comfort, energy efficiency. Passive House is a concept based only on performance, that is adaptable to different climatic, cultural, economic contexts and has been implemented, studied and validated since 1991. Passive House offers the cost optimum solution for the Nearly Zero Energy Buildings standard.


With this progressive transition of the building stock to high performance levels, the following results are expected:
- the improvement of the quality of life of citizens;
- more efficient buildings and more efficient cities;
- adding value to the building sector in Portugal;
- the reduction of final energy consumption and CO2 emissions in Portugal;
- the more effectiv implementation of smart grids and micro grids;
- strengthen the energy resilience and enabling the energy independence of a community, city, region or country.
