I have been asked about my Passive House consultant training by other architects enough times that I though I’d write up a quick synopsis, one year later.
For me, the Passive House training was very useful for several reasons, not the least of which was the networking aspect. It is a small community with some really great conversation happening and it is fun to be a part of that. There is a lot of controversy as well, especially on GreenBuildingAdvisor.com Such as where does the law of diminishing returns kick in when it comes to insulating and how to handle latent loads (excess moisture). Plus there’s the whole U.S. vs the rest of the world thing which I won’t go into as I find it rather annoying, or at least boring. Secondly, It represents state of the art science on how to build good buildings with an overriding emphasis on simplicity and quality. Passive House is really all about quality and even, as I’m finding out, represents a necessary re-thinking of how to get something built. A much more collaborative approach is necessary than often happens when building even high-end projects. The process gets much less linear. I also like the idea that the Passive House approach is a valid part of the conversation, not just achieving certification and getting the plaque to hang beside the front door. I see projects being showcased that utilized the approach in a value engineering manner to get the most bang for the buck that simply don’t have the budget to go all the way and attain certification and I like the general consensus that that is okay.
Much of my own work had been trending in the PH direction anyway so it was good to undergo the intensive training so that I could make decisions with much more confidence and authority that comes with PH credentials. As an architect who was never very (ahem) enthusiastic about the numbers and physics of things and more into the airy-fairy poetic nature and scholarly aspect of architecture it was also helpful in terms of training my weaknesses. I call myself a Passive House designer rather than a consultant in part because If I were to attempt a full-on certified Passive House, I would want to hire someone more experienced who does this on a daily basis to do the actual numbers part and look over their shoulder through the process – at least for the first few times.
There is also the notion, similar to my approach to structural engineering where I try not to design anything too complicated to engineer myself – I prefer not to design anything that would require a complicated heating/ventilating system. It does get more complicated in renovation/addition work though for sure. My approach to structural engineering has always been very intuitive and very related to my own building experience and knowledge of materials, assemblies and connections My structural engineering professor once told me that the intuition part is vital and more than half the battle. First you intuit the solution then you apply numbers and formulas to check yourself. The Passive House training augmented my intuition and gave me more confidence to apply the numbers as well as a perspective on when, where and why.
Plus it was really good for marketing.
