Is This What You Want From Housebuilders?

We have potential development near us which, naturally nobody wants. I went to the viewing of their plans with the purpose of plugging this method of building. To my astonishment the chap knew of Fully Charged and took notes of my description of this episode. They had planned to be as sustainable as possible but seemed really interested in finding out more. As an ex-sales person I pointed out that if they developed like this it would be their best promotion of their project and would be more likely to get permission.

[@jameslewis2635]

The people behind this project have the right idea. In times like these where the average house price is well above £200,000 in many areas, an extra £20,000 on the initial purchase cost is a relatively small ammount when you are talking about mortgage payments in comparison to the ever rising costs of gas and electricity in traditional homes. Now we need to see something like this brought in to convert existing properties to similar specifications.

They should all be facing south and be solar passive. I've built my house in Australia facing north, with eaves that shade the windows in summer when the sun is high in the sky and let the sun in in the winter when the sun is lower. Just doing that means that it hardly needs any heating and, more importantly in Australia, it doesn't need air conditioning.

[@dalroth10]

What a brilliant video of a fantastic development of new, exceptional homes. What is being done at Parc Eirin should become the template for new Planning and Building Regulations if the UK is to get anywhere near the net zero aims it has committed to. I think most potential buyers would recognise that whilst the initial purchase price of their home might be a few thousand pounds more, the amount they would save in energy costs in the first few years would pay for it. From then on they're in profit in a warm, comfortable, environmentally friendly, cheap to run home. I also reckon the resale values of these homes will be higher too.

Fantastic. Bulk pricing on PV is so cheap already, and when you can add it to the mortgage cost it's basically negligible.

[@David-bl1bt]

I have recently placed a reservation on a new build "eco" home. Although not perfect, the builder has made some efforts to make it more efficient. It is very well insulated and has solar panels and electric underfloor heating. No gas to the property which for me, having had a career solely within the gas industry, was a hard pill to swallow. Something that my new home also incorporates which strangely is very rarely or never mentioned, and is not mentioned in this video either, is MVHR (mechanical ventilation heat recovery). As home efficiency is focused upon insulation values and elimination of drafts ventilation needs to be addressed. MVHR systems provide many unrealised benefits other than providing adequate ventilation, such as the elimination of condensation which in turn prevents mould growth (a hot topic here in the UK currently due to a toddler dying due to lung infection caused by a damp home full if mould growth), removes stale air from the home including cooking smells, CO2 & germs emitted by our breathing, carbon monoxide emitted from fossil fuelled appliances such as a gas hob ir open fire foe example. All are extracted from every room in the house to the outside and replenished by fresh air from outside if the home. The transmission ov viruses and germs are considerably reduced too. Additionally the heat contained in the extracted air is removed and transferred to the incoming air. The system is 90% efficient at heat transfer. Fresh air that enters the house if filtered, thus removing external contaminants and allergens such as pollen which induces hay fever for example. As there us no need to open windows for ventilation, there is no ingress of these external contaminants, no ingress if noise and no loss if heat. I find it astonishing that these MVHR systems aren't given publicity in programmes such as these that are promoting sustainability, energy efficiency and well-being, and the lack of home builders and architects to not giving give due consideration to such systems as part of the "eco" credentials of properties. Come on Robert, promote the full eco story please.

[@SolisNotSolis]

All well and good, but electric is still 4x the price of gas per kWh and solar generates least at the time of peak demand, i.e. dark, cold winters day..

[@David-bl1bt]

@@SolisNotSolis ...don't forget to factor in that electricity is 100% efficient, for 1kw purchased you get 1kw of heat...not so with gas. The typical efficiency of a gas boiler is 60-70% When solar is producing electricity it is reducing the demand for electricity you need from the grid. If you also have a storage battery this is charged by solar for use when solar is not available eg. During the evening or charged from the grid at off peak times at a considerably less cost per kW hour. If you have an electric car this can be charged by solar and at off peak rates making the running costs considerably less than a petrol or diesel car, so these savings should also be factored-in. Then of course there is the bonus that you are not spewing carcinogenic toxins into the atmosphere for people to injest into their lungs that future generations will be thankful for.

[@pinkelephants1421]

Brilliant! One thing that should have been addressed was the impermeability of the driveways & carparking. I'm quite surprised that this wasn't addressed at the planning stages - particularly in soggy Wales - as, as far as I know, you're not supposed to install an impermeable driveway as part of future flood management in the face of climate change without express permission from your local authority and this is supposed to (only) be allowed on the basis of disability access. From memory, this was introduced several years ago on a UK-wide basis. I also noticed that in some cases the asphalt footpath ran right up against the houses leaving potential for rising damp in the future instead of leaving a small gap for drainage. This might sound as though I'm nitpicking but we're regularly seeing the horrendous & costly flooding impacts people are experiencing in their homes of increasingly climate change induced heavy rainfall in Wales, sometimes repeatedly within a 6-24mth period and this is projected to worsen over time. Insurance could well become unaffordable or even inaccessible to some property owners due to flooding risks so anything we can do to assist with drainage & water sequestration really matters; well designed & built infrastructure has a huge impact. Other than that, the developers have done a wonderful job.

Compared to the same level of use and mileage last year, on the exact same fuel tariff (with Octopus - who are ground-breaking), we saved ~£270 just from mid-Sept to mid-Oct, when you take into account home electricity savings, export of spare electricity to the grid at premium prices and charging cars from home (instead of buying diesel). And that is on a tarif paying 19 pence per kWh. If we were paying 35 pence a kWh (which many are), it would have been closer to £350 - in ONE MONTH!

This is truly a great initiative very well done to all involved. However, Seeing as the government has sanctioned the mass building of housing stock to “stimulate” the economy, right across the country, the least they can do is make property developers build in these features on any new development. I live near the the “wonderland” / cutting edge city of Milton Keynes and development is rampant.

I am doing exactly the same In renovating my 1920s house. However it’s taken over 2 years and costs have spiralled.

[@knowledgebyte]

They’re a gnats-whisker away in the US and Holland of 3D printing small and affordable housing using waste products like wood materials from sawmills. Brick building will therefore end and builders will be forced to use modern materials that have little need for concrete and old building techniques. I’m about to design my own house and will be looking at printing modules you can snap together. Hof Haus are another good example of sustainable building.

[@TomTom-cm2oq]

I would love an illustration of the cost of this home 5 years ago. How much more expensive was it? Which tech DIDN'T we have? Would it have paid off back then? If all the answers are positive, then why is this only happening now?

[@buckles29]

Does having a 3-phase electrical supply allow a higher export limit (3.68Kw currently on single phase) from the DNO ?

[@devonbikefilms]

I believe it does. It also allows for an up to 22kw wall box charger as well. The industry will no doubt resist this approach for as long as possible…..

[@skybenedict]

Yes in theory but I don't have intimate knowledge of G99 etc. The limit is put on to safeguard supply voltage staying within 230V +/- whatever threshold. Substation voltage is set slightly higher than 230V, taking into account losses and should arrive at loads within that parameter. The problem with large export is, one runs the risk of reversing the voltage, squirting out too high a voltage. So if one has 3 phases, you can just export 3.68kW in each phase.

[@richardash6945]

Yes, the amount of export you can have _without a specific agreement_ is 16A (3.68kW) per phase - a three phase property in the UK can do 16A on each phase, so 11kW total. You can apply to be allowed more in either case, but it might be expensive. The first 16A per phase you can't be charged extra for or turned down (a provision originally from EU law).

[@MrCarnivoure]

Yes, missed opportunity now for last couple of years with new developments where they didn't take advantage of energy efficient housing right from the get go. Now with energy crisis , people took lifetime mortgages with traditional gas heating and many may loose their houses as mortgages going up as well 😳

[@douggray169]

excellent video, great ideas

[@GoCoyote]

My experience is that most existing buildings can be upgraded to include many of these design elements, just at a much greater cost than incorporating them into new construction. My idea as that every building should have an energy audit every time they change ownership, are rented, or a new tenant moves in, and every 20 years if no sale or tenant change. If the Audit finds deficiencies from maintenance, that would need to be remedied. All buildings would need to be brought up to new energy codes in order to be sold, transferred, or rented.

[@tonyclark5854]

You would think if the builders were to there to show off there newly built houses, that the electricity companies outside service boxes would have doors on, to prevent rain from faulting the electric service equipment inside ? Plus the electric service cable entry ducting could of been installed vertically straight 😮

[@davidfellowes1628]

The question you are asking the Building industry and every facet of it is why they are so slow at coming forward? Five years after the Grenfell fire, which at the time was obviously negligent, still nothing has been done to rectify all those other similar buildings, nor to change and modernise the practices of the overall building industry. And, why it is so hard to get comprehensive good advice, rather than an array of conmen selling only one dubious part of a solution. Madness, sheer madness. And at the same time insane that the state allows such affairs to persist. Go overseas, there are many many examples of how best to proceed in the publics interests.

[@robinbennett5994]

You're right, but this is the 'shilling green products' channel, aimed at the mass-market instead of us energy nerds. The rants are only on the original Fully Charged channel. I would love to hear answers to all those questions, but I suspect it's "the Tories".

[@robertsprigge5535]

Having just listened to the 203rd episode, having already racked-up 100 hours of listening time, of the excellent BBC Podcast, 'The Grenfell Tower enquiry' I agree. Even the police are now saying they'll wait for the final report in a year's time before prosecuting anyone! In previous episodes, you can hear the various Coroners' reports which, if enacted, could have made a major difference to the outcome. The financial folk don't count future energy saving for the resident, just the cost of construction, i.e. an extra £20k🙁 I want to get the example in this video into phase 2 of our Neighbourhood plan to give it legal status.

[@simongigney2138]

I know I likely won't get an answer. But how expensive is that thermal heating system cost. Say if I bought some freehold land an wanted a long term plan

[@celt1578]

What about transport infrastructure? Is it well connected by cycling, walking and public transport routes? That will have a huge impact on the carbon footprint of the development.

[@haldo691]

So how energy efficient are the houses should be triple glazed windows foam filled frames minimum of 200mm insulated cavity walls some form of centralised air handling to prevent windows needing to be opened for ventilation

[@alanmuncaster7357]

Yes this is the way we should be building houses. But... down here in Dorset there is one developer who adds a covenant preventing the owners installing PV panels unless they and the neighbours agree. Such a short sighted approach.

[@jrisner6535]

I thought I'd seen this before!
