The old and the new can live in good harmony- The grey house that was built in 1860 got the passive house treatment with 170mm of extenal insulation behind the ventilated fasade last year. The red house is brand new, a standard Scanhome Skagerrack 304 with 355mm of wall insulation within the timber frame constuction.
Someone pointed out that it might be a good idea to get a good house now, before the value of your “money” is inflated away. With a wood / turf burning stove and solar collectors for total independence. The object in the middle will maintain it’s value as well as a passive house over time…..
One of these things tune
This Monday was quite exiting before we got the 23.000 liter seasonal store tank in the basement connected to the 50 m2 of solar-panels on the roof of the old building. The small tank of 3.300 liter (located in the stairwell of the 1860 house) could not handle the heat generated by our solar-collectors. We had 110 degrees water coming down and it was coming close to boiling. We had to ask the tenants to leave the heat on and open the windows to cool off the system for a while.
On Tuesday 13th of May, Åke Häggmann, Peter and Tobias connected the finned copper tubes in the bottom of the tank. Finally there is somewhere for us to pump away the superfluous heat from the roof. It will be interesting to measure up the various flows and temperatures to analyze the functionality of the system. This is done by Dr. Shane Colclough as part of the EINSTEIN research-program.
It is a pity that the collectors are shadowed by the Library-building across the street for the winter months, but of course, that is partly the reason for building a seasonal store in the first place.
The super-erection-team Flaherty and Goaley with Peter, John, Darragh, Ruadhan, Adrian and Cathal are plowing on. After two weeks of construction the roof is nearly completed with clay tiles and all. A good bit of extra seal-effort around the roof windows are always done by Scandinavian Homes when we install these problematic windows. (all roof windows are, this is not connected to any particular manufacturer)
Triple glazed roof windows are sometimes supplied with an extra frame with a bit of foam for insulation of the frame. But we see major flaws with this. Rainwater and wind penetration. A hopeless “apron” is supplied with the kit and this is supposed to keep wind and rain out. Worst possible detail, just a cover-up so you cannot see how poor the methods of sealing are. This is of extra concern in well insulated houses where massive amounts of roof insulation will soak up eventual water for years. To make it worse, the vapour barrier on the inside of the insulation will prevent detection of eventual water-leaks. Problems will be hidden for years and the risk is that the roof is rotting away under the roofwindow(s).
We are currently building a small apartment-building in Lysekil, Sweden. Located on top of undulating granite rocks behind our office. On this location a merchant house was located from 1846 onwards. The main building, a timber panelled log building from 1860 was carefully renovated to passive standards by our Irish team last year. This time it is a lot easier, Scandinavian Homes standard methods for modular construction makes the build process very fast. The reaction from the locals in this small Swedish town is that they have never seen anything being built as fast.
An oddity for this build is that we skimped on the inner layer of plasterboard that is normally factory fitted. Reason is that when we build in the late spring, only 2km from our factory, the risk of rain damaging the exposed insulation is minimal.
Timeconsuming to fix the external cladding on site. Normally this is done in our factory. This time we really wanted to stay true to the mid-1800 feel to the location, so to avoid visible horizontal joints of the panel, we install the panels on site.
