We continue our series of articles on thermal efficiency of windows, describing the glass edge thermal bridge.
As far as thermal bridges go, this one is inevitable, and it represents the weakest point of a well designed thermal envelope. It needs to be analyzed carefully, in order to prevent condensation (or ice) to form on the edge of the glass, discomfort, and an overall drop in the performance of the window/door. Read More
To achieve thermal comfort and energy efficiency in buildings, a primary role is played by the thermal envelope: this is required to thermally decouple the indoor environment from the ever-changing external conditions, both in summer and in winter.
The structures of the thermal envelope need to be able to control the amount of heat migrating through them: the thermal resistance and the thermal transmittance are two ways to describe this phenomenon. Read More
The lambda value of a material indicates its ability to transfer heat: this property is therefore very important in the design of highly performing buildings and passive houses.
The information commonly available is unfortunately quite confusing: with this article, we’ll try and shed some light on the topic. Read More
With more and more people talking about building energy efficiency and passive houses, it has become more and more common to hear about insulation. In this article, we explain what an insulation material is, to try and shed some light on the topic, and bust some myths. The energy efficiency of a building, as well… Read More
The construction system certification is possibly the least known certification offered by the Passivhaus Institut, and yet it can help spreading passive buildings all over the world.
We worked on the first system certification for passive houses in a warm climate: we try and explain what it’s all about. Read More
For new builds as well as energy retrofits, worldwide the construction industry is shifting more and more towards zero energy buildings and Passive Houses.
With the thermal envelope becoming more and more advanced, the correct evaluation of thermal bridges becomes critical: with this article, we explain the PSI value. Read More
