Conversion and update of this website

We are in the process of converting this website in line with the new style of the Blewbury website. After the conversion we will be revising the individual pages to bring them up to date with developments over the last two years, and to enhance them with more pictures. Pages where the text has not been updated significantly are identified with the status message
"Converted latest date"
When we have reviewed and updated the page the status will be shown as:

Diary of Activities

September 2005: Sample questionnaires We asked a small sample of people from different house types to fill in a questionnaire on the features of their houses which affect energy usage. The results would be analysed to provide a report for each household surveyed. This had two aims: to obtain an outline of household energy issues, and to help develop a survey to be offered to all households in Blewbury.

December 2005: Website launched The energy website was launched as a subset of the Blewbury website. It is intended to provide information supporting the aims of the Blewbury Energy Initiative, and to provide a general introduction to energy issues.

January 2006: Sample questionnaires analysed The results from the sample questionnaires were analysed by a program and returned to those who filled them in, with an explanatory note. The results, though helpful, were only indicative because the lifestyle of each household was not recorded.

January 2006: Revised questionnaires distributed An improved questionnaire, derived from experience with the sample, was circulated to every house in Blewbury with the Blewbury Bulletin. Those who returned the questionnaire received an energy survey report and two low-energy light bulbs. The website included advice on how to find the answers to some of the questions. This advice is now archived on a separate page as we are not currently supplying these questionaires.

February 2006: Infrared survey of selected buildings On a cold night, a team from Thermascan took infrared photographs of about 30 buildings in Blewbury. The results need to be interpreted with care, taking account of the effects of electric light. Some buildings have hot spots that are probably caused by specific building issues. In many buildings there is a warm area under the eaves, where the gap to allow air into the roof space also allows warmer air to escape. Integral garages can lose significant heat through and over the garage doors if the garage area is not well insulated from the rest of the house. Outside drainage pipes can carry heat from the bathroom. Internal radiators against a solid outside wall heat the garden if not insulated. Drawing curtains has a very obvious effect.

March 2006: Energy survey reports delivered Energy survey reports were delivered to nearly all who had returned questionnaires. (A few were delayed as the analysis software did not produce a sensible report on the first pass.) The reports gave an indication of measures that may improve home comfort whilst reducing fuel bills and carbon emissions, and included information on no-cost or low-cost measures, as well as the District Council-backed discount insulation scheme. The key findings are: Whilst many homes have some loft insulation, many would benefit from a top-up. There is scope for a much larger uptake of low-energy light bulbs. Blewbury has higher than average use of cavity-wall insulation, although a number of properties could still benefit from this. Efficient hot-water tank lagging, and the use of hot-water tank thermostats, is much less than expected. Several of these improvements are cheap and easy to install, and would have fast paybacks.

May 2006: Energy footprint of Blewbury estimated A spreadsheet of all Blewbury properties was produced, and the results of the analysed energy surveys were entered. From this, estimates of the average CO2 contribution from each type of property were made. The result was as follows: a carbon footprint of 5136 tonnes of CO2 per year, generated by 707 buildings, giving an average of 7.2 tonnes/year/building.

June 2006: Monitoring electricity usage At the Blewbury Village Society Open Day, and in follow-up discussions with the home energy surveys, it became apparent that most householders have little idea of how much electricity they are consuming at any point in time, and many get a horrible shock when the bill arrives. The Energy Initiative identified an energy monitor then called the Electrisave, evaluated it, and arranged for a bulk purchase for residents who wished to buy one. The device is now called the OWL Monitor.

September 2006: A report on our initial work was published.

September 2006: The aims for the next period were defined These were as follows: To find and publicise practical solutions to the domestic energy issues that arose from our surveys. To expand our investigations and education on renewable and alternative energy options suitable for the community. To seek to help community buildings and local businesses to improve their energy efficiency.

November 2006: Articles in the Blewbury Bulletin A series of short articles were published in this monthly magazine.

January 2007: Alternative energy for the home An evening meeting on this topic was held in the Methodist Chapel. The options were presented and discussed. Some specialists and a regional installer of alternative technologies were available for the discussion.

April 2007: 'An Inconvenient Truth' There was a free showing of this Oscar-winning film on climate change in the Methodist Chapel, followed by a discussion on the issue and how we can all 'do our bit' here in Blewbury and beyond. About 50 people attended. This was an initiative of the Blewbury Environment Group.

June 2007: Exhibits at Blewbury Festival There was an Energy Initiative stall at the family-day fair at the Festival. During the Exhibition weekend a working solar PV installation in a garden was on display.

July 2007: Survey of business premises We contracted a professional company to survey the premises of those businesses in Blewbury who agreed to this, to investigate their energy consumption, and to make recommendations for saving energy and costs. This was subsidised by use of our Oxfordshire Sustainability and Conservation Award.

November 2007: Survey of business premises completed The results of the survey the premises of those businesses in Blewbury who agreed to this were delivered.

November 2007: Review of electricity monitors Dr. Sarah Darby, of the Environmental Change Institute at Oxford University, visited to get feedback from the users of the Electrisave monitor in Blewbury. This was part of her research into consumer displays of energy information. We also used the interviews to get feedback on the work of the Initiative, and what they thought we should be doing in future.

March 2008: Research on electricity consumption We researched the standby consumption of different devices. The surprises were

• the large number of devices often left on standby in a typical home,
• the wide variability of the standby power requirements of similar devices,
• the high standby consumption of the plugs used to power some portable devices such as radios, and
• the number of devices that take significant power when apparently switched off

July 2008: Conversion and update of the website A major revision of the website is being undertaken, beginning with a conversion to a more modern style in line with the newly revised Blewbury website.

Awards

• Biodiversity and Grounds Development

• Waste Minimisation, and
• Water Efficiency

At the presentation on the 19th October, 2006 the Blewbury Energy Initiative was presented with the Gold award for the category "Energy Efficiency and Renewables". This came with a very welcome prize of £1000 which was used to further our work. This year there were also awards for "Environmental Community Champions", and this website gained recognition with its webmaster being chosen for the Silver award.
