First US EnerPHit hotel is a beauty
What did you do on your family winter break? I took mine to a PHI-certified EnerPHit hotel, the first of its kind in the US. I really enjoyed our stay. I snuck into the all-electric kitchen (yeah, I was kicked out pretty quick) and it looked pretty standard except for the welcome absence of giant gas burners spewing particulate pollution. …
New carbon calculator integrates with PHPP
We built The Carbonator, a simple tool calculating building embodied and operational carbon emissions and it is now available so all Passive House designers can use it. Visit sustainableengineering.co.nz/thecarbonator/ for a free download of the tool, to watch a recording of the webinar and download the slide deck.

PHI timber thermal bridge catalogue worth downloading
PHI has released an extensive catalogue of 600 timber frame thermal bridge calculations, plus a results file in Excel format that shows the resulting PSI values. The goal was to create a timber thermal bridge catalogue that was manufacturer independent—and which included varying construction thickness and U-values so that intermediate values could be interpolated (using the Excel file). The catalogue …
Essential to manage risks from moisture in CLT buildings
There are some advantages to being laggards in adopting new building products and methods. CLT is more common in Europe and has a longer history of use there. Damage and failures have occurred even in buildings less than five years old. It’s making insurers nervous and some are applying higher premiums to CLT constructions. Some key lessons about protecting against …
Aggregate heat loss testing (coheating) standard released
Good news: a European Standard for heat load testing has been released. I hope it will lead to more research that measures the performance gap (if any) between the heating load predicted by design stage energy modelling and as-built performance. Heat load testing is also known as co-heating testing, it’s a measure of a building’s thermal performance. The standard uses …
Design and build your own Passive House Premium off-grid home
Maria’s Passive House is in select company whichever way you look at. Few New Zealand Passive projects are rural; only three are certified to Premium performance; it’s believed to be the country’s only off-grid Passive House; and it was designed and built by its owner, Steve Hughes of Build Good Architecture. This minor dwelling is a vital stage in …
Wildfires also kill people through fine particulate pollution
This paper on PM2.5 pollution caused by wildfires estimates the number of Americans killed by wildfires—not the fire itself but the fine particulate pollution in the smoky air. It has implications for New Zealanders and it’s worrying. “We estimate a total of 52,480 to 55,710 premature deaths are attributable to wildland fire PM2.5 over the 11-year period with respect to …
Streamlining Passive House design
There’s some anticipation about the release of easyPH, understandable given its promise to make Passive House design easier. Here’s some advice for new designers about how to streamline and simplify Passive House design, some of which is applicable to either PHPP or easyPH. Firstly, make sure you’re familiar with the subset of projects that can be designed using easyPH. This …
