Low energy homes exhibition a success

On 21st January 2012, the exhibition of low energy homes attracted about 130 people interested in seeing the homes on show and listening to the talks. With stall-holders displaying a range of technologies from Rushcliffe Borough Council's light-bulb library to full scale home refurbishments and renewable technologies, there was a lot to see. To read about the stalls, talks and afternoon house tours in more detail, read the full write-up here.

A very big thank you must go to the exhibitors and a super team of Transition West Bridgford / Eco House Group volunteers who worked hard on the day to make it happen and to provide a warm welcome to the visitors.

This exhibition marks the final event in our "Eco Houses under Construction" series, but don't worry - there will be opportunities to see these homes and others in the future.

Thanks to our recent successful LEAF funding bid, there will be further house visits and a set of workshops due in March, so look out for our "Homes Behaving Badly" events. The idea is to make sure that these workshops are as relevant as possible to those who come along. Knowing that West Bridgford has more than its fair share of solid wall homes and large areas of cavity wall housing, different workshops will focus on different types of homes and the associated low, medium and high cost solutions to cut energy use.

As well as looking at all the feedback from the exhibition, we would like to know if you live in a cavity wall home or a solid wall home, and what issues and options you need to know about in more detail. A questionnaire is coming soon!

Eco Houses Under Construction - Event 5

On 12^th November, a dozen people gathered to find out more about barn conversion in East Leake that will soon become zero carbon. David Hill (now Managing Director of Carbon Legacy Ltd.) turned the old dairy into a comfortable, highly insulated space. If you think that going low carbon is for the “hair shirt brigade”, think again – this is definitely luxury low carbon living!

Good air quality is provided by the MVHR system (mechanical ventilation with heat recovery), which draws stale air out of kitchens, bathrooms and the utility room, and sends warmed fresh air into the main living spaces. (This makes the utility room a great place to dry clothes simply because of the air flow.) The system was extremely quiet (well, I didn’t even notice it), although it could be heard in the utility room where the MVHR box was located.

 The house design ensures thermal comfort thanks to insulation, controlled ventilation rather than cold draughts, and plenty of “thermal mass”. Thermal mass is present in the form of stone floors and stone or brick walls – these absorb heat to keep the house cool on a hot day, and release the heat as the air cools in the evening.

Energy is provided in a variety of ways:

The forthcoming addition of more PV panels to create a 10kwp system, will equal the entire annual energy consumption of the house (10,000-10,500kWh per year). Furthermore, the imminent installation of an inverter with intelligent control system and batteries (called Power Router from Nedap in Holland. www.powerrouter.com) means that this house will continue to have an electricity supply even if the rest of the area suffers a power cut!

Solar hot water panels supply hot water during the summer months, and a ground source heat pump provides heat to the under-floor heating system. Recently, a pellet burning stove in the main living area has been installed in case of power failure or temperatures below -10 degrees C or when the main heating system has not been switched on.

Eco Houses Under Construction - Event 5

The 5th event in the series will take place on Saturday 12th November, 2-5pm.

This is a rare opportunity to visit the UK's first Zero Carbon Barn Conversion, just down the road in East Leake. The developer (and owner) of this home is David Hill, who previously developed the UK's first Code 6 new build Zero Carbon homes in Upton, Northampton. He is now director of Carbon Legacy Ltd.

Although not still "under construction", this house has the advantage of 3 years' energy data post completion, showing that the approach taken has worked.

(For anyone who attended the series of Eco House Seminars which we ran this time last year, you may remember that David presented a talk on low energy refurbishment, and also contributed to the seminar on renewable energy for homes.)

For more information or to book your place on this free event, email Tina on info@wbecohouses.co.uk

Here is David's summary of the house:


·         Super insulated 9” solid brick walls
·         Factory made Insulated roof panels (SIPS)
·         Super insulated floor slab with wet under floor heating (ground and first floor)
·         Extensive use of thermal mass in floors, internal walls and ceiling
·         Whole house ventilation with heat recovery 90% efficiency
·         Triple glazed timber windows with aluminium outer skin (Rationel)
·         Draft lobby with highly insulated doors (Rationel)
·         Air tight construction with measured value of 2.3m3/m2@50Pa pressure
·         Thermal store fed by oversized Solar Hot water panels and heat pump for space heating and domestic hot water

·         10kwp Solar PV system installed in December which should make us carbon neutral in energy use. Half of the system also feeds a new type of inverter (Nedap Powerrouter). This will do 5 important tasks: Send power to the house as it is required, when the house does not need the power divert it to a large battery store, in the evening when the house is calling for electricity turn the battery power into AC and send it to the house, during the day if the house does not need power and the batteries are fully charged then export power to the grid, should the Mains Grid supply fail then the unit will continue to feed converted power from the batteries into the house independently.

·         Ground sourced heat Pump (GSHP) providing space heating and some of the domestic hot water
·         Experimental Sunbox providing Earth charging energy from solar and ambient air to improve the efficiency of the GSHP
·         Rain water recycling from underground tank to provide water for toilet flushing and garden irrigation
·         Presence and daylight sensor light control in common areas of the house
·         100% low energy lighting and low energy appliances
·         Planning permission and foundation pad for a 10-15kw VAWT wind turbine for when I find one that works!
·         Reserve wood pellet 5kw stove in case of power failure

Interesting facts/results:

·         It works!
·         It has met its target energy consumption with 3 years’ worth of all power consumption (electricity) 10,500kwh/year
·         If we had the 10kw wind turbine (long story) or when we install the 10kw or bigger Solar PV installation then the house will generate as much or more power than it consumes.
·         It may also provide free electricity to charge 2 electric cars the first of which is due to arrive in 2012
·         The family loves it because it is comfortable and pleasant to live in all year round

Slimming or slashing the heating bill?

Insulation and draught-proofing

22 Oct: Tina Holt writes: At the second event in this series of talks, David Hill of Carbon Legacy gave an overview of the aspects to consider when reducing heat loss from a building. He included some very useful facts, figures and general advice. This covered insulation of walls, roofs and floors, what to look out for when considering new windows, and ways of reducing draughts and providing suitable ventilation without excessive heat loss. A short report summarising the options is available on request from info@carbonlegacy.co.uk.

Following the talk, people put their own questions to one of the experts present: David Hill, Tim Saunders, Sean Stevenson, Gil Schalom, Mike Siebert and Sheila Hood. Some of these conversations were continued in the pub!

Choosing PV Panels

2 Oct '10: We get quite a lot of questions about 'Which panels to use' - this is difficult to answer, as it takes 25 years of living with them to know if a class of panels is truly successful, and what the replacement percentage may have been in that time. Some panels are tested merely by quick 'Flash' tests, and that says nothing for the 25 year  reliability of the panel or the responsiveness of the manufacturer to technical queries or claims.
  David Hill of Carbon Legacy has written a long and detailed article on Rushcliffe Solar site about some of these questions.  http://rushcliffesolar.blogspot.com/p/panel-details.html
