So we need to be ercareful, really careful, how we manage this opportunity.
Down with that sort of thing!
Your completely correct in cutting through the greenwash. We havent the luxury of waiting for the builders to upskill. We have to be master builders and teach them how to build. I spend most my time standing over builders screaming at them for using expandable foam which is a terrible product for airtightness. I’ve become obsessive compulsive about air leakage, dont get me started about moisture migration, I could rattle on like Stephen Hawkins for hours.PHPP isnt object orientated its an excel spreadsheet, it allows you input local data from a website or an on site weather station. The defaults are Dubin Airport or Birr. The BER gives relative energy estimates compared to a bad reference house. Its not a design Tool. I’ll send you a sample PHPP work sheet if you PM me
I ‘m doing an unsustainable but ultra low energy Passive house for near â‚¬100 per square foot builders finish in a nice rural location (for an Urban Client). I’m more businessman than principled greeney, but as Amory Lovins said, ‘We are the generation we’ve been waiting for’. No Excuses. If your client wants a minimum standard house, then tell him he’s an idiot( with all due respect). Design him a slightly smaller space but build him a technically much better house.
