Home energy efficiency grants re-starting soon

The Green Deal Home Improvement Fund (worth up to £7,600) was launched in June and axed just 6 weeks later due to popular demand.

However, it has been announced today that the grant scheme will re-open before the end of November, with an additional £100million in the pot. So if you missed out last time, it's time to check it out again.

Update: Phase 2 of the grant scheme started in December 2014. Phase 3 is expected in March 2015.

Whether the grant is as generous as previously (for example, offering up to £6,000 and later up to £4,000 towards the cost of External Wall Insulation), remains to be seen.

If you are considering various options to make your home warmer or to cut the energy bills, it is a very good idea to do your research and think it all through carefully. Maybe get some quotes. Then if the grant scheme does start up again, you are poised and ready to see whether it will help  you, and if so, to make the most of it!

There is a handy report about energy saving options from zero cost to high cost on this site, co-written by me and an architect who specialises in low energy buildings including refurbishments. Just go to the "HOBBS Report" on the second tab - it is free to download.

If you live in or near to West Bridgford, then there's local help at hand. With our Transition West Bridgford thermal imaging camera, we can now show you where heat is escaping from your home!

Tina ( / 07962 453037) uses the camera as part of a whole house assessment to highlight energy saving options which might be suitable in your home.

Open Homes, Thermal Images and Cake!

It's been a busy couple of months!

The Open Homes days in May are now over but if you missed out and would like to join the waiting list for next time, just email (Scroll down to find a summary of each home which opened its doors this May.)

Visitors and householders alike enjoyed the days, with some people just visiting out of curiosity and others taking notes and picking up tips for their own homes.

And then, we celebrated the end of the Thermal Imaging Camera pilot project with a bit of a gathering and some cake. The cake was so great we just had to put a couple of pics here. (If you have seen thermal images of any houses from the outside, you'll like this cake!) It also tasted fantastic - not just a pretty cake!

(If you'd like to receive an email when we start up the thermal imaging surveys again in the autumn, email and ask to join the waiting list.)

Open Homes events across the East Midlands

This May (2014) there will be a huge range of low energy and sustainable homes opening across the UK for interested householders to visit for free. It's a great way to suss out ways to make your home more comfortable and reduce your energy bills.

Many of these events are supported with funding from the Centre for Sustainable Energy, and all the homes are listed on the Green Open Homes website.

Within the East Midlands, there will be our own "Transition West Bridgford" event organising open homes visits in Beeston, West Bridgford, East Leake and Market Bosworth (!). Every home is described in a series of posts below, and also here on the Green Open Homes website.

And we are not the only ones!
There's the "Nottinghamshire and Derbyshire Open Homes Week" here -  (some of our Transition West Bridgford homes are listed here as well, being in the same geographical area).

Then there's the Nottingham Green Door tour here.

And Loughborough Energy Efficient Homes here.

Or if you are north of Nottingham, then maybe Green Homes Sheffield is closer to hand.

Open Homes May 2014 - This year's theme - seeing heat loss!

This year, we have 7 great open homes and a new display.

Details of the 7 homes are in the preceding posts (below). And they are pretty diverse, including two homes that will be "mid-refurb", some extreme refurbs, 2 new builds and a cavity wall insulated house that has cut its energy bills in half with very moderate energy and cost saving measures.

Our theme this year is "seeing heat loss" - because we have been out and about with a thermal imaging camera. We'll have displays up in each home showing good and bad examples of the places where our homes typically lose heat.

For most of the homes open this year it is necessary to book your place - details are in each post below. This keeps numbers manageable and gives you a better chance to see and hear everything!

We send out directions and other useful information (e.g. bus routes, parking etc) to those who book a place, and if for any reason a tour has to be cancelled or rearranged, we can notify you if we have your contact details.

Read on, book on, and I hope you find this year's Open Homes enjoyable and useful!

Open Homes May 2014 - House number 7 of 7

Last but by no means least on this May's open homes list is a 1980's cavity wall insulated house.

It may not sound a likely candidate for a low energy home, and certainly this is not as low energy as the other 6 homes in previous posts. However, when the current owner bought this house, it had an energy rating of F!! Basic improvements (e.g. loft and cavity insulation, draught-proofing and a new gas boiler) along with common sense habits have cut the bills to around half!

There is no need to book to visit this one - just drop by any time between 11am and 3pm on Saturday 10th May and head for the gazebo in the front garden (the left branch of Worwood Drive in Compton Acres, West Bridgford).

Like the other homes open this year, there will be a thermal imaging display to show good and bad examples of the places where draughts and cold spots are typically found in our homes. The home owner (a qualified building surveyor) will be on hand to talk about DIY solutions.

Open Homes May 2014 - House number 6 of 7

Our 6th Open Home this year is on Charnock Avenue near the Queens Medical Centre in Nottingham. Like home number 5 (see previous post), this is an ambitious ultra-low energy refurbishment - and it is mid-refurb!

To book your free place for the 2pm tour on the 18th May 2014, click here.

Here's a summary of progress so far:

An Edwardian bungalow loft conversion and whole-house ultra low energy refurb.  This project is in progress and many interesting features will be still visible.  
Most U values and thermal bridging to exceed Passivhaus minimum.  Passivhaus style detailing.
160 mm PIR external wall insulation taken below ground to footings.
400 mm EPS floor insulation with slab in the middle and edge insulation down to footings internally.
Loft conversion from below the roof structure and tiles left in place.
Consolar Tubo 12 solar thermal and innovative 500 litre thermal store.
Underfloor heating.
Flexible pipe MVHR by Airflow.
Green Building Store 'Ecocontract 48' external windows and doors set in ply box liners.
High levels of air tightness and ambitious target.
Gas boiler with underfloor heating in the screed.

Pit around the house dug, eaves insulated ready for EWI, which is expected to start in April 2014, ground floor underway.

Open Homes May 2014 - House number 5 of 7

Our 5th Open Home this year (on Wollaton Road in Beeston) is "mid refurb", so it really is a great opportunity to see the nuts and bolts of what's being done now while you can still see the insulation and other elements that will eventually be hidden.

To book your free place for the 2pm tour on the 17th May 2014, click here.

An extraordinary self-build project to significantly extend and energy efficiently refurbish a mid Victorian semi-detached villa.  The owner is carrying out most of the work himself including some fairly serious structural challenges and braving all weather.
Single storey rear extension shell complete including green roof, Passivhaus style timber frame and oak cladding.
Large side extension substantially underway including a full size basement built next to the existing house which alone took a year owning to needing to underpin sections, build retaining walls and beam others.  Superstructure of extension 3 storeys above basement in Porotherm clay interlocking lattice blocks 365 mm thick (complete) with 100 mm EWI over (planned).
Green Building Store windows throughout, different ranges.  
TJI engineered floor joists.
PV on the workshop.
Solar thermal planned on large dormer roof.
Wood pellet boiler planned.
Double height conservatory planned.

Roof should be complete and windows installed ready for EWI.

Open Homes May 2014 - House number 4 of 7

On Peveril Drive, West Bridgford, just up the hill from house number 3 (see previous post) is another seriously low energy home - achieved in a very different way.

To book your free place for the 12 noon or 4pm tour on the 11th May 2014, click here.

This house was built with extra cavity wall insulation and has subsequently been fitted with solar hot water panels, solar PV panels, a ground source heat pump linked to 2 "sun-boxes" and more recently still a PVT system.

The owner is a technical expert on this system, using it for cutting edge research into the levels of efficiency that can be achieved with a ground source heat pump.

Open Homes May 2014 - House number 3 of 7

Our third open home (Harrow House / Towards EnerPHit) is an ultra-low energy refurbishment which was designed to meet the EnerPHit (Passive House refurbishment) standard.

To book your free visit to this West Bridgford home, click hereNumbers are limited so that you get the best from the visit, with time to put your questions to the home owner during / after the tour.

Although the air tightness figure of 1.08 ACH narrowly missed the target of 1 ACH required for certification, the performance of the house is definitely in line with the EnerPHit standard.

The house provides comfort and excellent air quality in hot and cold weather. Gas use for the last year was a tiny 4800 kWh (heating plus hot water) and electricity bought in from the grid came to 1500 kWh.

In other words, gas costs around £200 per year (plus a standing charge), and electiricity costs almost exactly the same. Altogether, this means that we earn more for the electricity generated by PV panels on the roof than we pay for gas and electricity.

The secret is the Passive House methodology - insulation, air tightness and a whole house ventilation system with heat recovery. The thermal mass prevents overheating in summer and keeps indoor temperatures steady all year round.

Open Homes May 2014 - House number 1 of 7

Of the homes we're opening to the public in May 2014, this is the first to be featured here in the run up to the open days.

The Green Man House is a new build to almost Passive House standard, and it's near Market Bosworth! It may seem a little way outside Nottingham, but it's a great house so it would be a shame to miss it out.

Owner Peter said

"Of the number of approaches to building a ‘green house,’ we decided to emulate the Passivhaus standard. We decided on a timber frame construction built off site, with good insulation, air tightness, solar water heating, and a ventilation system with heat recovery. The house was orientated and designed to take advantage of the warmth of the sun within a fairly tight site.

The house has performed well since it was completed five years ago, although it just failed the Passivhaus air tightness standard. A log burning stove is used on colder winter evenings to bring temperatures up to a comfortable level and to boost the hot water supply."

If you would like to visit this house, click here to book your place. Numbers are limited so that you get the best from the visit, with a chance to put your questions to the home owner.

If only we could see the heat escaping from our homes....

Well, you can of course see heat escaping from a house using a thermal imaging camera. Taking photos inside the house shows the cold spots where the cold gets in (i.e. heat is lost). From the outside, you see hot spots where escaping heat emerges.

In December 2013, Transition West Bridgford put in a bid for funding to buy a thermal imaging camera and now we are ready to use it!!

If you live in or around West Bridgford and think you might be interested in a thermal imaging survey of your home, get your name on the waiting list here. There's no obligation - this is just so we can contact those who are likely to be interested in a home survey or a community event showing the typical areas of heat loss.

We hope to carry out the visits in March (before the weather gets too warm).

For the full details, here's the press release:

E.ON’s Energy Action Fund powers Transition West Bridgford’s energy education

Community group, Transition West Bridgford, has been awarded a grant of £1,790 from energy company E.ON to promote energy efficiency across the local area.

The grant from E.ON will enable the organisation to purchase a thermal imaging camera, which will be used in free educational events for local residents. These workshops will help residents to understand how energy is commonly lost in the home and subsequently how this can be reduced, potentially resulting in lower energy bills.

Images from the camera will also be used in educational materials and online to raise as much awareness as possible across West Bridgford with the wider community.
The E.ON Energy Action Fund is part of the company’s commitment to helping local communities use no more energy than they need, benefitting both individual groups and the wider community.
Jake Jackson, Treasurer at Transition West Bridgford, said: “The funding received from E.ON will have a positive impact on the local community. The camera will not only be used to support educational events and materials, but also to carry out paid thermal imaging surveys for individuals and businesses.

“The funding raised through these surveys will provide long term support to Transition West Bridgford, enabling us to continue running the awareness raising events.”

Amy Cross, Senior Community Relations Executive at E.ON, said: “We’re really keen to support this project as it has the potential to educate many people across the community and the initial funding will help this to continue. We hope this will make a big difference to local people.”
