    We had a planner visit our site and he reckons best we’ll get on it is a one and a half storey house. We’re looking to build something very well sealed, leaning towards passive. Will we encounter big problems with our upstairs windows? We think we’re going to have to go for dormer style windows and to me that sounds like a lot of heatloss….any thoughts? Thanks.

    redesign the dweling so it has narrow forms and thus you may get a 2 storey house....
    many storey and a half dwellings have ridge lines at 7.5 m etc... youd easily get a 2 storey with a ridge like this, it will mean having a longer narrower forms, but even this is better for passive gains....

    employ a good architect with good knowledge of how to maximise solar gains...

    Dormer windows are a disaster for heatloss, you cannot insulate them adequately.
    You would be better to fit velux windows, they can be got in triple glazing from Germany, these are better fitted few and big rather than little and often.

    Really? I thought that velux would be worse. Interesting.

    So looked up roof windows, fakro and velux look like they're worth further research. Has anyone any thoughts on skytubes?
