In the UK almost two-third of the houses failed to meet the long-term efficiency targets, According to data analyzed by the BBC. There are almost 12 million homes that are under the C grade. The grades were marked on a scale from A-G of Energy Performance Certificates (EPCs). When the houses fall under the C grade category it means that their expenditure on energy bills is high and they produce more CO2 than the necessary amount. The government of the UK stated that they have to work faster and move further to improve energy performance.
Experts suggest that a retrofit solution must be employed due to the fact that most of the houses were built before 1990. This is one of the biggest projects post-world war2 and it will significantly help the country reach its zero carbon target by the year 2050. The efficiency of the house will be measured by the EPCs based on the property’s glazing, insulation, and alternative methods that are deployed to reduce energy consumption. The houses are graded from A to G and when a house is graded under A it means that the house has a smaller carbon footprint and lower energy bills. G is the lower end of the grade and C is considered as above average.
