Detailed research into the energy use of SuperHomes reveals that, on average, they are using 40% less energy per square metre per year than the average UK home. SuperHomes are, therefore, much cheaper to run than their unrefurbished neighbours.
The most energy efficient home in the study, whilst offering improved comfort, uses a staggering 86% less energy than the average home.
One of the participants in this research, Simon Brown, is no stranger to the benefits of retrofit. He says “After the first year, we were pleasantly surprised to find our total gas and electricity bill was slightly less than in our previous home, which was half the size.”
So, whilst low-carbon and low-energy don’t necessarily go hand in hand, this study confirms that SuperHomes excel in both respects.
The research report shows that an average SuperHome:
The most energy-efficient SuperHome in the survey (refurbished to the exacting Passivhaus standard) was found to use just 25kWh/m2/yr, an impressive 86% less than the national average.
Gabby Mallet, Director of SuperHomes and Households and Communities at the National Energy Foundation, commented:
“Many people assume that a low-carbon home is also a low-energy one. However, this is not necessarily the case … it’s fantastic to discover that many SuperHomes have not only gone much further than a 60% carbon reduction, but they’ve achieved great results on energy too.”
SuperHomes are older homes refurbished by their owners to deliver a carbon saving of at least 60%. The owners host free open days in September to share the benefits and the challenges of home refurbishment.
Researchers at the National Energy Foundation (NEF) calculated the energy and carbon figures for a representative sample of the existing 205 SuperHomes, by per person per year, and by per square metre of floor space per year. Using the 2012 National Energy Efficiency Data-Framework (NEED) sample, NEF was able to make comparisons between an average SuperHome and the average UK home with the same number of occupants or of the same size.
