The Energy Saving Trust (EST) describes Hard To Treat (HTT) homes as having poor energy efficiency ratings with the energy efficiency having been based upon the Standard Assessment Procedure (SAP) criteria. SAP rating was developed by the Building Research Establishment (BRE) renowned for their certification and training standards.
SAP, a scientifically standardized and recognized methodology, is used to identify and measure the energy performance loss and retention from commercial and noncommercial builds from heat in water and space. The purpose of having a standardized assessment enables accurate comparisons be made between builds of different size; age; purpose; and material composition. Having this assessment tool drives environmental housing-related policy progressively forward to dynamically improve energy efficiency in all builds.
Having an A SAP rating states that a build is energy efficient whereas a G rating is extremely energy inefficient. According to EST (2011) energy inefficiency’s prevalent in almost three million UK dwellings and has lead to fuel poverty in those homes because the residents use more energy to heat their dwelling to an acceptable standard in the home’s rooms; boilers; and heating systems and at a higher than acceptable cost. They base the higher than reasonably acceptable cost as taking more than ten percent of the household’s income.
With regards to the environment the escaped energy warms the local climate and therefore contributes to climate change due to the roaming Green House Gases (GHGs) which are able to chemically react with other gases and infra red sunlight.
In their report, Hard to treat homes and fuel poverty, EST cited the Energy Efficiency Partnership for Homes who realized that HTT homes cost financially more to treat using normative energy efficient schemes that aide installations of loft and wall insulation. In 2010 energy efficiency schemes were reviewed in Parliament who stated that there are now four million homes suffering from fuel poverty. The results of which ought to impact upon households and energy producers by reducing the number of homes in fuel poverty whilst placing a Duty upon the suppliers to facilitate recommended solutions to customers. However the increasing number of suffering homes illustrates that although many homes have benefitted greatly from the schemes, one questions whether The Warm Homes and Energy Conservation Act 2000 underestimated the volume of HTT homes within the UK at that time?
Since the Act was enabled the government has been the driving force to reduce roaming GHGs from homes. One such scheme was the Carbon Emissions Reduction Target (CERT) which placed the onus upon energy producers to increase the energy efficiency of their customers’ homes. However the onus was to promote energy efficiency and not to supply it for free therefore how are customers suffering from fuel poverty expected to pay for the technologies which they clearly need?
Do not lose heart for all is not lost.
The Energy Efficiency Partnership for Homes have continued on their quest to comprehend householders classified as vulnerable adults and households having low incomes with regards to funding available technologies to help those identified households. The householders, using Green Deal from Department of Energy & Climate Change, are able to assist homeowners who own and rent the homes therefore enabling a greater percentage of fuel poverty sufferers to access the scheme.
Their target audience fits with findings published by the Communities and Local Government Summary which noted that the highest volume of homes that didn’t reach a decent standard were owned and that almost forty percent of vulnerable householders lived in homes that had not reached their decent standard.
Crudely to improve a build’s SAP rating for builds off the gas supply the energy ought to derive via Combined Heat and Power as this is highly efficient due to it capturing and utilizing heat that would conventually have been lost to its local environment.
However in the Summary available by ScienceDirect, Oreszczyn et al. (2005) insulation is a key component in improving energy efficiency in living rooms and bedrooms.
To conclude, there are wide ranging variables affecting energy efficiency in HTT homes. Therefore the UK needs continuing support from government agencies and the general public so that energy inefficiency will one day remain only in history books.
