A sort of follow-up to the Post on CPD<\/a>; sometimes following a CPD session it really pushes you into a rethink on the way you’re doing things.<\/p>\n

After a CPD session on #PassivHaus we had a site visit to the lovely, in-construction, soon to be certified, passive house of Architect Cuala McGann and it really made me think about u-values we’re currently working to.<\/p>\n

What’s amazing in Ireland is the overwhelming use of blockwork, cavity construction. No matter how much you try it’s very difficult to get the client mindset to adjust to a warmer, easier to airtighten and faster to construct method that is timber frame. What was incredible at Cuala’s house were the resulting u-values of such a construction – what could possibly be the lowest u-values in Ireland, if not Europe.<\/p>\n

Let’s go back only a few years; 2008 regs had wall u-values at 0.27 W\/m2K; to achieve 2012 compliance you’re looking at practically Passivhaus standard of 0.15 W\/m2K. Remember that you can’t now rely on backstop u-values to ensure compliance HERE IS A BLOG POST ON THAT TOPIC<\/a>. Cuala’s house has a wall u-value at 0.07 W\/m2K; that’s nearly a 400% improvement on a value only 4 years ago!. And it’s done in a wall construction and materials that are entirely naturally-made! ( Gutex from Ecological Building Systems<\/a> ).<\/p>\n

Although not complete, the house is well on the way (photo above taken at the end of the day), a special thanks to Cuala McGann for showing us around the benchmark of passivhaus construction.<\/p>\n","protected":false},"excerpt":{"rendered":"
