Advanced Building Science Standardization to the Rescue – Emu’s interview on AOC Podcast

We’re almost famous. It’s kind of a big deal. Our interview on the Art of Construction podcast has gone live. If you can handle listening to Enrico and me stumble through the introductory questions about our favorite drinks and travel destinations (you would think that wouldn’t be so hard to answer), we do actually answer… Read More

Emu’s interview with the Insulation Institute: “For Better Homes, Is it Net Zero or Passive House?”

Our very own Enrico Bonilauri was recently interviewed for NAIMA (North American Insulation Manufacturers Association), the most recognized voice of the insulation industry on this side of the pond. Their mission is “to enable a more comfortable, energy efficient and sustainable future through insulation”, so we welcomed the opportunity to give our two cents on why… Read More

The glass edge thermal bridge: the PSIg value

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

Energy efficiency of windows: the Uf value

After covering thermal transmittance U and resistance R of opaque assemblies, and insulated glass, we now cover one of the most critical areas of the thermal envelope: window frames.

Good windows are the cornerstone of a performing building for both comfort and energy efficiency, specially if it is a passive house. Read More

FensterBau 2016 in Nuremberg

Last week we went to Nuremberg, Germany, for the 2016 edition of FensterBau, one of the most important expos worldwide for window production.

Target of the fair is the entire sector of windows and openings. The event is organized alongside the Holz-Handwerk expo, addressing wood carpentry in the broadest sense. Read More

Mold and condensation: if the solution is worse than the problem

We cover here two real examples of mold and condensation problems, with thermal insulation installed on the inside of existing masonry walls.

In both cases, the solutions were chosen on an empirical basis, and turned out to be worse than the problems they were trying to mitigate. Read More

What’s an insulation material?

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

Certified construction system for Passive Houses

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

Colorado: our work ties become permanent

With Mariana currently involved full time with Natural Capitalism Solutions and AE Building Systems, our professional ties with Colorado are now solid.

This allows us to have experience in highly efficient buildings on both sides of the Atlantic, with some initial interesting considerations. Read More

Airtightness: why is it so important?

With this article, we address one of the most important topics in the field of energy efficiency: the airtightness of the thermal envelope.

Whether the building is a new construction or a renovation, its airtightness plays an important role for comfort, energy efficiency and durability of the structure. Read More
