This is the story of a lucky, very timely coincidence. Back in February 2018, as part of our curriculum development for North American Passive House training, Emu Systems added a hands-on workshop to the Certified Passive House Tradesperson course. After collecting feedback from participants in our 2018 Colorado and Montana courses, we upgraded 2019 workshop… Read More
Moisture in buildings has become increasingly worrisome for construction professionals in recent years. American buildings are subject to a wide variety of defects related to water in its different forms – liquid, vapor and sometimes snow and ice. These range from thermal discomfort, poor indoor air quality and health hazards (mold), all the way to… Read More
With U.S. building codes now starting to address air tightness with respect to energy efficiency, many builders find themselves struggling to meet the defined ACH50 values (air changes per hour at 50 Pascal) required by their local codes. This measurement is an assessment of air leaks as monitored via the pressurization of the whole building… Read More
Notice: please read to the END of this article, and note the date. #thingswethoughtwedidnthavetoexplain 😉 Gally Tullagher, a builder in Red Lodge MT, was court ordered to refund $5k in damaged testing equipment to the company performing the blower door test — a procedure designed to measure air leaks in a building. “We set up… Read More
Contrary to popular belief and the professional opinion of many, recent study shows health benefits related to living in moldy buildings. Read More
We took part to the “Train the trainer” class, organised by the Passivhaus Institut of Darmstadt on the days following the 2016 edition of the International Passive House Conference.
The class is geared towards passive house experts, who intend to become teachers in the Certified Passive House Designer/Consultant class (CPHD/CPHC) and in the Certified Tradesperson class. Read More

With this article, we cover two very important aspects of glazings: light transmission and the solar heat gain coefficient.
These parameters are extremely important for performing buildings and passive houses, however they are often overlooked by both designers and window manufacturers. Read More
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
