Energy Efficiency: the importance of site supervision

On our Facebook page, we are regularly publishing images from our Cavriago construction site, where we are building two Passive Houses. With this article, we would like to show just two examples of the many construction errors can occur during the scope of the works, proving that careful site supervision is necessary to meet a high level of quality and efficiency.

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 test so early in the construction process. Here is a brief overview of the benefits...

A Disastrous Case Study: How Replacing Windows Alone Can Lead to Mold

In our previous articles, we have cautioned that an energy retrofit should be approached with an integrated, whole-building approach, and by a professional with experience in calculating and simulating thermal envelopes. The photos below show what happened to one family's home when they decided to do an independent partial energy retrofit, without consulting a qualified professional. In this case, they decided to replace the old windows of their house with newer, high performance windows, hoping that they would be able to reduce their energy consumption.
