Incredible house! Love this project and the heart behind it. Well done T&M!
"The quality of live makes up for all the efforts" ...thank you for such a clear statement. Great example.
Thanks for such an encouraging comment, and for all your efforts over the decades in conceiving and promoting Passivhaus
Fab Stuff! Great video - thanks for the virtual tour :)
Great video, this is on my doorstep and I didn't even realise
Do come and see us sometime. It would be great to meet.
Love the ethos. Love the house. Just a little surprised about the rockwool & the bricks. Any reason why straw bale panels weren't used?
I felt we were always treading a fine line between innovation - and I think we were being quite innovative at the time we made key decisions in 2017 - and cost risk. Time has proved that many of the innovations have proved entirely justified, particularly those relating energy generation and management. Would we have done it differently new? Of course, that's life and we should always allow experience to teach us.
The house was designed by an architect who had developed a good working relationship with the builder we used. They had confidence in working with each other again to deliver to PH standards cost effectively, and the price we were quoted (and the price we finally paid) were, I consider, both fair.
Straw bales are generally used by self-builders and are a really good way of building sustainably. But we would have lost a lot of space to achieve Passivhaus standards, and I'm not sure that there's a strong body of knowledge to draw upon on how to reliably reach those standards using straw. Others may have views about this.
Bricks are an interesting one. Lots of variables at play here and, in retrospect, I think we'd have probably gone for more timber boarding and less brickwork, but in 2017 there was very little hard data about embodied carbon.
But in reality as we found out, in retrospect applying PHribbon, that the key decision as regards embodied carbon was the use of a reinforced concrete foundation raft. Should we have asked more questions about this? Yes, certainly. Could we have significantly have reduced its carbon footprint? Probably.
But we did what we could with the information available at the time and are pleased that we went for closed timber panels with a major degree of timber cladding. What else might we have done differently? Less Rockwool and PIR? Possibly, Shingles instead of concrete roof tiles? Perhaps.
They say one has to build three custom/self-builds to get it right. We will make do with one, thanks. We love the house too!!
@@timl9730 thanks for your in depth reply. Wonderful house....wonderful home!
Hi Tim, loved the video. Did you say how it is heated? You talked about solar gain etc but I can't recall seeing an air source heat pump or something similar, I presume it would need something extra.
We installed electric (cable) underfloor heating across the whole of the ground floor plus two small areas (under ceramic tiling) in our two upstairs bathrooms, each controlled by local thermostats. The cables are set into the cement screed immediately below the finished flooring. If these were on 24/7 in the winter these would be easily sufficient to keep room temperatures at 20 degrees. In practice, we tend to have them on only overnight to take advantage of cheap electricity, and then supplement with a plug-in fan heater on very cold, cloudy days when there's liitle in the way of solar gain. We also heat our water electrically off-peak with the large water tank acts as a thermal store, though on sunny days this is unnecessary as the surplus power goes into the water tank after filling the battery.
You're right! We would definitely feel cold Nov to Feb without a heating system. We installed a very simple electric underfloor systems, with thermostatic and time controls. So no heat pump. Our energy bills are so low (c£350 pa) that we felt it wasn't worth the additional capital costs associated with installing a pump and associated plumbing and electrical installation. The main underfloor electric cable is laid in the ground floor screed with two circuits - for south and north facing rooms, as heating requirements can vary significantly. (Lack of solar gain on cold grey days together with large relatively heat-leaky windows can mean that the south side needs more heat, but the reverse is true on slightly warmer sunny days.) We also have underfloor heating in our tiled floor bathrooms, where the floor can feel very cold in winter. We have deliberately 'oversized' the heating capacity so we can mainly warm the house overnight on cheap electricity, and generally we only run it at these times. It's a bit cheap and cheerful, but we have been known to plug in a small electric panel heater in the evenings following grey and cold winter days! Fortunately we were able to get feed-in tariff subsidies for our PV array and, over a 12 month period, our FiT payments are slightly greater than our energy bills.
Hi. Does the passive house standard have any restrictions in terms of maximum living space per person? A builder in the industry told me the standard only allows a certain square meter area or volume of space per person, implying that a relatively large house for, say 2 people, for example wouldn't pass the standard requirements. Are you aware of such requirement?
I'm not aware of such a restriction. It certainly didn't apply in 2019 when our certification was completed.
If you've found this video helpful, you may care to move on to a further RUclips recording posted by Phil Bixby, our architect - ' ruclips.net/video/uZiBKaX2yJo/видео.html Start 3:45 into the recording to view a short presentation by us on the wellbeing effects we have experienced living in our new home. We explore why Passivhaus leads to a more comfortable and healthier environment and explain how, by designing an energy efficient home, we ended up with a better life!
