Damn i just found one of these on the ground and was like what is this. lol seems to be in fine working order too

As a builder, the fact that you put a project like this out to tender is a huge problem, asking multiple people to spend so much time and effort to cost such a project will cost each company thousands of pounds, Did the architect or engineer have to bid for the project? Did they work to a pre agreed fee? More likely the architect and engineers charged per hour plus a minimum set The builder says himself, he was £100,000 out of pocket, and will have caused severe delays to other jobs in his diary. It all just seems that it's the people who physically do the work, are the way way undervalued, disrespected, stereotyped, controlled, and scrutinised, workers in the process.

Boa idéia. Muito criativa e original. Parabéns

Very impressed with how much your DIY MVHR install cost you (£1300). However, reading your most recent post below, even the extreme measures you took to achieve air tightness were not quite enough. MVHR can actually make a home less energy efficient by pulling in more air through the leaks of a building, instead of capturing heat from exhausting air. I work as an energy assessor for a charity, and your energy efficiency rating suffers if you have MVHR ! This is because the software assumes that retrofitted homes are basically unable to meet the required level of air tightness to prevent this unwanted effect of making the house even more leaky.

Does this camera record videos as well?

Thank you !!

Great video and an inspiration to do my own retrofit project this year. I have a few questions about some details, is there a generic email to contact you on? Unfortunately I'm not that close to Cambridge otherwise I would be coming along to the monthly pub meetings!

This is great. 🎉 temporary and easy to work out. I love it. Thanks. 🙏🏼

Thanks Tom! The effort you guys put into this scheme is amazing! :)

Not sure how easy it would be, but could the temperature switch be used to turn on a power supply when the operating temperature is reached? This way there would be no power consumed when the fans are not needed.

I’ve just seen this video a year later; very educational and inspiring. For the 2021 energy consumption due to working from home; a tip for those that can; a Chromebook or Apple MacBook will consume much less energy than something running intel and windows. My work laptop (a modestly fast HP) uses a 115Watts charger block, gets very hot and often runs it’s cooling fans. Many MacBooks and chromebooks don’t even have a fan (and don’t get hot) because they use use so much less energy.

Brilliance

2023 update: We finally got an airtightness test done which came out at 1.52 m3/m2 (at 50 Pascals). That's not as good as the 1 ach that EnerPhit should have but PHPP says even with that we should get to 32kWh/m2.yr once the floor insulation is complete. (Currently we are at 41 kWh/m2.yr)

There is almost nowhere where people discuss having EWI and IWI together. It would be useful to see yhat covered more.

clever, cheap and tasteful

A step by step on how to build would be highly appreciated 🫡

Clever idea.

Very clever!

A really interesting talk, thanks

Genius, easy and inexpensive, thank you!

technically this can work for baseboard heaters too, nice idea

What was the TV programme?

Good morning I'm enquiring about a w i I have come across a company that promises to be able to do the job skillfully, my concerns are that they want a deposit upfront I'm just a bit nervous about giving money before a job is done. Companies based in Ipswich because I'm in Felixstowe. I would appreciate any help you can give me in this matter look forward to hearing from you. Thank you.

Would be good to see more videos each with a focus on a single bit of work that can be done in a weekend. For example a video that focus on insulating the door step. Then DIYer have a weekend focus guide video for each of the projects they can take on.

Oh fab, I just completed the survey after training to say links to videos on how to use these cameras would be good, and voila! Great, thanks!

Thank you

Great helpful video; love the car radiator fan to pressurise or depressurise the house! ThnX

Wookey - I think I remember your handle from the old Navitron forums circa 2007/8!

Hi, like your your video. Thanks

I'm not convinced there's much net benefit here

How do you make the full screen thermo

Brilliant

Apologies for the lack of sound in the second half. Not sure how to fix that. th-cam.com/video/PAEvR9vsf5A/w-d-xo.html This is a similar talk that I did with another family also talking about how they retrofitted.

Argh! I was really enjoying this and finding some of the ideas very useful - and then the audio cut out for the rest of the presentation… If you have a copy with the full audio, please upload it or otherwise, how about running the second half in a new presentation? Thanks for the excellent content.

How do you work out what size awning you need? The angle of the awning?

I'd love to make these, they look perfect. Unfortunately we have side opening windows meaning that I think the window pane, when open, would block access to the hooks and the supports. Any ideas to adapt the design?

The sound cuts out for the second half

thank you Tom and Anne. Did you hem the fabric yourselves using a sewing machine? Very useful description, thank you for all your work.

Hi, thanks for this. Do you know if the fabric blocks UV radiation? It says it's reflective, so I guess it does, but can't see anything confirming it on the website. I'd like something like this in my garden to provide sun protection. Thanks

The amount of money must have been astronomical. I'm very much for upgrading our house, but there has to be a reasonable pay back time for me (apart from HMRV, I regard that comfort).

THIS TECHNOLOGY WILL BE USED TO TARGET THE HUMAN RACE FOR TAXES AND ALSO PUNISHMENT FOR NON COMPLIANCE OF THERMAL REGULATIONS...SHAME ON YOU.

55:20 Talks about powermeters. This type is very good: th-cam.com/video/fRGKilvExMo/w-d-xo.html Widely available for under £15

Muito bom

Thanks Wookey. One of the more interesting talks on retrofit projects. Thanks for the detail.

Thank you for sharing this excellent video. It's nice to see some practical solutions

how did you attach the larger shade to the wall? I have used a pop up 10 x 10 canopy for patio shade during the summer, but the cover ripped the next year. I'd like to use the frame and add shade cloth. anyone seen that?

Continuous, goes on forever, I think you mean contiguous Mr. Bob 👸

This is perfect for what I want to use for my patio. The deck above me always drips down on my patio. I can't have anything permanent and this is perfect.

Nice work! Really enjoying this series and getting good ideas for my own project :)

Thanks for the presentation- lots of useful tips :) I stuff padded envelopes in air vents initially but now upgraded to recycled polystyrene packaging cut carefully to the air brick! (eventually I'll remove it). Kudos for also generally trying to lead an environmentally friend lifestyle. Looks like a petrol chainsaw though? Maybe the replacement can be electric charged from solar PV :)
