... claimed to be "the first house in the UK to be entirely solar heated all year round". Basically, he has a GSHP extracting heat from 48m deep boreholes. Purpose built 'sunboxes' dump solar thermal energy into the borehole, etc., etc. An excellent example of solar tech in action.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256329#Comment_256329 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256329#Comment_256329 Sat, 25 Mar 2017 10:00:38 +0000 gyrogear

If you're heating a Passive House with a Solar Roof, install a large area of Solar Thermal at a 65°angle to optimize yield over the heating season and you won't need a heat pump. I built Ireland's most energy efficient house in 2010 using this method http://viking-house.co.uk/solar-enhanced-passive-house.html for the last 6 years its average electrical bill was €130/annum or 750kWh/annum. It uses 4kWh/m2.annum for heating, hot water and electricity so beats the Passive House Premium standard introduced 2 years ago hands down. Here's the Solar Heating Dartboard that shows the optimal angle for Solar Heating, sorry its in German.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256348#Comment_256348 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256348#Comment_256348 Sat, 25 Mar 2017 16:42:13 +0000 fostertom http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256375#Comment_256375 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256375#Comment_256375 Sun, 26 Mar 2017 09:35:48 +0100 John Walsh http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256379#Comment_256379 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256379#Comment_256379 Sun, 26 Mar 2017 11:18:22 +0100 Ed Davies

Only if they've been overdesigned. Tom's point is that the passivhaus specification requires just enough insulation to make the specific heat demand 15 kWh/m²/year wherever you are in the world (or 10 W/m² max heat load). If you use more insulation than that you are overspecifying (i.e. wasting money, in a rather narrow sense).

But I agree that the discussion isn't specificaly about passive houses.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256414#Comment_256414 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15001&Focus=256414#Comment_256414 Mon, 27 Mar 2017 13:31:18 +0100 gyrogear

(The latitude is 48°N and I was about to propose that one could extrapolate the roof angle as being the hypotenuse of a right triangle ? thus (? "give or take carpenter error" = 48°...)

however, per discussion sites, it appears not to be a true hemisphere...).
Just for interest's sake, they only rotate through 33°, and most owners only ever go through 180°, apparently...

Ho-hum, back to parallelipipedism...
