Why Passive House?

Building to the Passive House Standard[1] reduces our buildings’ operational energy demand to an optimized extent through passive measures and components such as insulation, airtightness, heat recovery, solar heat gains, solar shading and incidental internal heat gains.   Passive House reliably delivers up to approximately a 90% reduction in heating and cooling demand and up to a 75% reduction in overall primary energy demand when compared to our existing building stock.[2]…

Tintin goes Passive

Belgium, the country that brought us Tintin, the reporter-turned detective, is in the midst of another great adventure. Belgium has finally found the culprit in its high energy costs and CO2 emissions which translates directly into loss of money and global warming. The culprit was always hiding right under their nose and worse yet in their homes and places of work: poorly insulated buildings. This was the perfect villain for Tintin to confront with energy savings strategies.…

PHI airtightness maximums compared to current USA airtightness code requirements

By Floris Keverling Buisman, reposted from  Four Seven Five It has been argued by many that the air-sealing requirements set by the Passivhaus Institute are too strict, unrealisticly low and thus too costly. However, the kind people on the other side of the Atlantic have shown that it is not hard to surpass these requirements by far, save both energy and prevent moisture and mold issues in walls. We are starting…
