The potential benefit of an early ‘Blower Door Test’.

In December we ran a 'Type B' Blower Door Test on our CasaClima Class A project, "Conte Re", under construction near Albinea (in the province of Reggio Emilia, Italy). Many of our colleagues wondered why we decided to run the…

Passive house: new construction or renovation?

In our blog, we are dedicating a large number of articles to deep energy retrofits, on one hand, and Passive Houses on the other. However, these two topics are not necessarily distinct from one another: here, we explain why.

How do you define the “health and comfort” of building occupants?

We often refer to the “health and comfort” of building occupants. What does this mean? An ideal building would be one that you wouldn’t notice or feel, one that would allow the body to exist in a healthy and comfortable…

Mold and condensation problems

Mold and condensation on the interior surfaces of a house's thermal envelope is a self-evident proof of poor quality and lack of comfort. It can happen on walls, roof, slabs and so on. These phenomena are symptoms of degrading building…

What is a ‘thermal bridge’?

In our articles, as we write about Passive Houses, thermal comfort and energy efficiency, we often assign great importance to the term 'thermal bridge'. We'll try to explain here what all the fuss is about.

What is the ‘thermal envelope’ of a building?

In our articles about building energy efficiency, we often use the term 'thermal envelope': let's define what we mean by that.
