South Wiltshire Green Doors

I mentioned this site, and I suspect we may get a few more people dropping in, as our blog URL here has now been tweeted and re-tweeted around a bit, apparently.
All told I was impressed with the seriousness with which the council are taking this, definitely not "greenwash" and those involved seem very down-to-earth when it comes to sustainability and energy saving measures, not at all like central government.

This event is an excellent idea. The people who have done it - made the changes and are living in the results - open their doors.
(much rather talk to the people who 'walk the walk' as opposed to salespeople with vested interests... apologies to salespeople everywhere)
Website looks interesting too.

I'd rather it was a talk to developers, with the aim of getting them to see that it needn't cost them money to have passive houses built, rather than rather poor standard houses, but it may help spread the word a little.

We're looking forward to seeing the house as part of the Open Day for South Wiltshire Green Doors

"Failure was not an option" lol.
You really are going above and beyond with your home, seems many more have had or are having the benefit of your experience :-).
Put a bath of the excess tile sealer by the front door and get the visitors to put the top coat on as they walk around :-D

After a bit of playing around I worked out that three low voltage terminals needed to be hooked together to simulate a call for heat, which now means I can do as I want and set it to control on flow temperature. Seems to work a treat, when on it holds the buffer tank at 40 deg C (the set flow temp). I can up this to 55 deg if needed, and set weather compensation to increase the buffer tank temp with OAT (using a sensor built in to the pump) so have an option to increase the thermal store pre-heat in winter. A nice surprise was how very quiet the ASHP was, much quieter than I was expecting, and at today's OAT (around 14 deg C and pouring rain) the fan on the ASHP only came on occasionally, and only ran very slowly when it did come on.

The worst one I had was wiring a Dimplex ground source heat pump. The manual detailed the "power" connections. So 240V power applied to the right place. But nothing. Nowt. Squat or whatever words you want to express the fact it did nothing.
Only after pouring over the wiring diagrams and tracing out their functions, did I find there were separate terminals to apply 240v "control" power. Those terminals were not actually mentioned anywhere by name or function.

Anyway, if anyone want to visit our house under this scheme, then please check out the site here: http://www.wiltshiregreendoors.org.uk/ They have developed a very useful (so I've been told) app that allows data to be captured on anything you're interested in, for later download and investigation. Our house is open for visits on both the 17th and 18th, and although not complete much of the energy efficiency stuff is in and working. You need to book a visit slot through the Green Doors site (here: http://www.wiltshire...homes/the-plot/) mainly because parking is very limited on the surrounding single track lanes, so we (and our steward) will be trying hard to schedule visitors through both days as best we can.
If you plan to visit then you need to be aware that the house is still unfinished, so there are some building site hazards around, and we are still reliant on a portaloo (none too pleasant - it's a standard "builders" version). We also don't have public health certified water on site yet, just the raw water from our borehole, so are unable to offer refreshments. We don't have any access issues, and the stairs are in and the whole ground floor is pretty much wheel chair accessible now.
There's no hard sell or commercial stuff over the weekend, it's a Council sponsored event to raise awareness of energy efficiency measures people can adopt and allow people to see things first hand and discuss them with those that have actually had stuff installed.

There are still spaces available on Sunday for anyone that wants to take a look around, book through this link: http://www.wiltshire...-18th-and-19th/ (scroll to the bottom for the contact details). There are details of our build here: http://www.wiltshire...homes/the-plot/

I was really encouraged by the enthusiasm for low energy house design and construction that so many of our visitors displayed, and very encouraged that we had a couple of architects visit today (which now brings the grand total to 9 architects that have been to see the house).
Very many thanks also to those who came bearings gifts, they were all very much appreciated (the home-made cake and the Welsh cheese were particularly enjoyable!). Our local MP has even expressed an interest, so perhaps there's hope that we can try and convince the powers-that-be that we should be building lower energy homes. I'm not holding my breath, though, as our present government seem committed to allowing the building industry to carry on building crap, at the expense of the eventual home owners who will inherit all the energy deficiencies from what is a virtually unregulated sector of industry.
I learned more about the way our house performs, too. The significant increase in heat input from having 9 or 10 visitors in the house was very marked, and could easily increase the house temperature by several degrees in a few minutes. I'm still learning a lot, but am already very grateful that I decided to spend the additional money on getting the Genvex active MVHR, as it performed very well at regulating the overall house temperature, despite large (for a passive house) variations in heat input.
