    I got so cold watching my kids play hockey I decided to become a coach. At least you keep moving. I will second that standing around doing bugger all requires the warmest kit around.

    But the sap calc is reliant on the stated air pressure test and achieving the figure

    Yes but the issue as outlined by hot_fiat is that you can have a house that was meant to be air tight on paper, but is not actually tested on site and ends up being a leaky sieve that no amount of insulation or solar panels is going to fix.

    It sort of gets my back up a wee bit, the delight with which people piss all over new build housing, as if buying a new build reflects some sort of lack of moral fibre on the part of the buyer.

    I only have an issue with rubbish developers not new build. I live in a new build that I designed and built myself and have worked for high end…[Read more]

    Not really the case. The calcs on a new build will have required much more than that, a pressure test requirement for starters.

    Developers do not even have to pressure test each…[Read more]

    The new build will only be ‘A’ rated because of the solar heating and that will not even supply all of your hot water needs for 6 months of the year. I suspect the new build would barely scrape a B rating without it, and much more important to know how much insulation is in it and also how well it was installed. There are a lot of stories of badly…[Read more]

  • you could try this. I used one last year for a couple of weeks and it was really good.

    I don’t buy the less solar gain thing. I designed and self built my passive house with triple glazed windows. Any extra solar gain in the short winter days through double glazing will be more than offset by the extra heat loss. As above comments it is great to be able to sit right next to the glass without feeling any chill off the glass.
