Not so much a blog as a weather report! Lots of fog, freezing the air and the ground, weakening the already weak sunshine. Creating a big fat inversion layer above Loch Lomond but allowing the grandeur of the mountains to rise above.
More news next time, we're just catching up with life and activities disrupted by the winter weather and preparing for the next lot. The fire's lit, we're warm and we're getting ready for Christmas. Best wishes.
Last Wednesday the joiner returned to fit this to the large upper floor window and on Thursday building control visited and all completion certificate and paperwork were handed over. Another key landmark in the creation of the house. The window illustrated is a fixed light 1.8m x 1.8m and affords a stunning view. We were so disappointed to be advised that this would need an internal barrier in place to comply with building regs. If we had known then perhaps a different design or different specification might have been created in the first place. Looks like a play pen.
BT have failed to meet four appointments to connect the phone. OK they pay compensation of £10 each time but we'd really rather have a phone line. So hopefully order number 5 will work...........
The wonders of nature never cease to soothe, we have an abundance of brown hares who are particularly visible in the early morning
No news is good news..and also reflects the lack of an internet connection.
We are in! Hurrah. The recent glorious weather has provided the best of starts with the sunshine emphasising how fabulously light this house is right through to late evening. Its not properly dark for many hours in this part of the world as we approach midsummer so the changing light outside is a constant delight.
Lots of building info to convey but the detail will have to wait a few more days, as will photos. Time and attention is devoted to our business and family needs at present. Unpacking is a slow process but we have everything we need. Having lived in a caravan for 9 months it is clear that our lives don't need most of the 'stuff' we have packed away in boxes so there's no urgency in that area. We've been concentrating on making sleeping and eating areas comfortable.
Quick info for today's blog;
1. We are SO pleased with our house. Satisfaction and feel good factor is high.
2. The quality of the architecture and the build is superb.
3. 3 points to resolve for building control i) one step on the patio is of a different height to others, ii) lashing eyes are to be provided for a window cleaner to clean the large first floor bedroom window and iii) on the same window there is ongoing discussion whether an internal barrier/rail needs to be put in front of the window - its a fixed light but the building control officer is considering this point, more later on that
4. Externally we live on a rather rough looking plot - plenty of work in the years ahead.
5. The apple trees are in blossom and look stunning.
6. The poorly hen has recovered completely and the hens are completely free range now that the chances of being run over have diminished. About 5 eggs per day are being produced.
7. The temperature in the house is pretty even despite it being hot outside and the MVHR is at its lowest setting.
8. The slate floor is particularly terrific in terms of appearance.
9. There is some snagging but not much except relating to the windows which have a good number of small issues to resolve. The supplier is currently proving slow to deal with them despite our first contact being around 2 months ago now.
10. Phone line being connected on Friday allegedly.
What we've set out to do at ECF is to build a house which will use 70% less energy than one built to current building regulations. Its timber frame construction detailing hasn't wavered too far from the 'norm' to present any major problems for a timber frame kit manufacturer, decent building contractor or building control, and the costs of going this 'extra mile' haven't been excessive to the extent that they will be paid back within a decade in terms of reduced energy costs.
In essence, we have built to a standard which is accessable now by most contractors and self builders which is around 5-6 yrs before its time if the UK Government is to fully implement its Code for Sustainable Homes (CSH) strategy, on which this building should come in at around 3-4 on a scale of 1-6. There is clearly some distance to go from this to 'zero carbon', so what represents the 'optimum' for 'Level 6 living', the magical zero carbon level required by 2016 for all new homes?
Well, the same principles apply, namely...
- building orientation to maximise solar gain in winter, spring and autumn whilst avoiding overheating in summer
- high levels of insulation around the entire building envelope
- high levels of airtightness coupled with heat recovery ventilation
- highly insulated and well sealed doors and windows
...but for CSH level 6 the wall insulation would need to be increased to >300mm (from our 200mm), roof insulation to >450mm (from our 350mm) and windows to be triple glazed krypton filled units with insulated frames and glazing spacers (vs. our argon filled double glazed units). This would result in a building which could feasibly rely on the heat given off by its occupants and collected though its windows to keep it at a comfortable temperature without having to introduce a heating system. Construction might rely on internal masonry/concrete walls to store heat and keep a steady internal temperature, with the insulation fixed to the outside of this.
On the face of it quite simple, but a seriously long way from what the UK housebuilding industry is used to. Roll on 2016.....there is a lot of catching up to do and mindsets to be re-programmed.
I've spent part of this evening contributing to a National Park meeting on renewable energy and sustainable building design and feel quite fired up on the whole subject. I came home, had a great discussion with Steve (before he went to Ikea for late night house shopping), then watched Grand Designs revisited about an underground house which essentially didn't need heating even in winter.
The whole debate about 'eco' and 'sustainable' is massively involved. We have built a well insulated, airtight, timber frame house with a thermal mass of 40 tonnes of concrete in the foundation slab to keep the internal temperature stable - that's great from an energy efficiency perspective, but is that scale of concrete usage a good thing, not least as the production of cement is an energy intensive process? Someone somewhere could maybe establish the whole life cycle energy equation.
Energy efficiency is a very important part of sustainability but I'm not sure if I can get my head around all of the issues. We've got fantastic argon filled double glazed windows with 'u' values of 1.4 (standard windows being between 1.8 and 2.0) and they are from Norway 'cos the Scandinavians having been building sustainable houses for years but ideally we should be buying UK produced windows in order to minimise transportation and support home industries...but it couldn't be done remotely near the cost as they would be regarded as 'one-offs' and 'specials'.
Anyway that's nearly enough...I looked at another blog this eve which prompted me to tell you about Earth Hour whereby you switch off your electricity at 8pm this Saturday for one hour. Its one of those experiments in activism which last year saw the city of Sydney reduce its 'leckie load by 10% thus illustrating the impact of individual actions.
