Nearly half of British homes do not have adequate insulation

New figures released on 17 June 2011 revealed that nearly half of Britain’s homes do not have adequate basic insulation and are throwing away at least £100 in wasted energy payments every year.

The latest lagging statistics show that only 57% of Britain’s lofts have been properly insulated and only 58% of cavity walls have been filled. Insulating lofts and cavity walls cuts down on energy leakage and therefore reduces energy bills.

Energy companies have been told by the Coalition Government to increase the help they make available to people to insulate their homes and save money. A total of 3.5 million homes are set to benefit by December 2012 as a result of a tougher Carbon Emissions Reduction Target.

Today’s figures show that 479,000 professional insulation measures have already been installed against the new target, with over three million further homes expected to be treated by the end of 2012. On average this will amount to more than 140,000 insulation measures a month.

Chris Huhne, Energy and Climate Change Secretary, said:

“At a time when money is tight and with energy prices predicted to rise, householders are missing out on over £100 of savings every single year by not getting their lofts lagged and cavity walls filled.

“We are making energy companies do more to help their hard pressed customers, with another 3.5 million households set to be protected against higher bills by the end of next year.”

People who want advice on insulating their home should call the Energy Saving Trust on 0800 512 012 to find out about the latest local offers on insulation that are available.

To help even more people transform their homes, the Government’s Green Deal will start next year. Households will be able to invest in home improvements at no upfront cost and repay through savings on energy bills.

The scheme will involve an extensive range of energy efficiency measures including installing insulation, replacing leaky windows, or upgrading inefficient old heating systems to the latest high-performing models.

Energy Heritage: a guide to improving energy efficiency in traditional and historic homes

This guide provides options for improving the energy efficiency in traditional and historic homes. It addresses the following questions:-

  • What issues affect energy efficiency improvements in historic buildings?
  • What opportunities exist to enhance historic homes?
  • What lessons can be learned from other experiences?

It includes a case study of a project carried out in an 1820s tenement building (a traditional Scottish dwelling type with a common stair) in Edinburgh, Scotland.

New microchip could prevent ‘standby’ energy loss

Japanese scientists have developed a new micro-processing chip which they claim could do away with the energy loss caused by appliances while on “standby”.

Existing chips in electronics that eat up energy when a device is switched off but plugged in could be replaced by the new microchip by 2015, claims NEC Corporation (NEC) and researchers at Tohoku University.

Gathering and Presenting Social Feedback to Change Domestic Electricity Consumption

A recent paper describes the CHARM Energy Study in which mobile technology is used to study the impact of social groupfeedback on household energy consumption. It describes the background and rationale behind the study, the technology which supports the study, and the study’s methodology. The work described builds upon similar studies by using mobile technology and on-line feedback to increase the frequency of accurate social group feedback to the participants.

Social Feedback on Web Interface

It is planned that all UK homes will have Smart Meters installed by 2020, and the EU Smart Meter market has been predicted to be worth 25 Billion Dollars US in the ten years from 2010 to 2020. Although the emerging UK standard mandates that UK Smart Meters will provide bidirectional communications and support in-house displays, the authors are unaware that there is yet a standard for the type of information that will be displayed to the consumer. If the study shows a real reduction in domestic electricity use resulting from social feedback methods, they hope that they may influence the emerging Smart Meter standard to providefor this means of change.

Project Charm – changing energy usage habits through the social norm

CHARM, funded by the RCUK Digital Economy Programme, employs digital technologies as a means of providing individuals with feedback about their own and others’ sustainability behaviours. Thus, the three-year project examines the potential for telling people what other people do – the so-called ‘social norm’ approach – to change individual practices and behaviours in socially-desirable ways.

Following the CHARM approach, they are developing digital technology to facilitate the capture and web-based feedback of household energy consumption data. The study includes approximately 300 households in a UK city. Over 18 weeks, the research will compare the energy consumption of three groups of households: households that receive no feedback, households that receive feedback only about their own energy consumption, and households that receive feedback about their own energy consumption and that of the other households in the study.

Research data will include energy consumption data, base line and post intervention questionnaires, longitudinal ethnographic interviews and focus groups.
