A TEESSIDE business's expertise has played an important role in research into how homes waste energy.
H Jarvis was one the firms recruited by Nottingham University, which discovered that using certain materials in new homes can reduce the amount of energy used by almost 72%.
The Redcar-based business – which has been making windows and doors used by builders, homeowners, schools and hospitals since 1878 – provided technical and manufacturing support for researchers.
The North East team helped to put together a “Passivhaus pod” – which uses extremely energy-efficient design – to be tested in real-life conditions by students living in them.
It used the EcoClear sealed unit, made by GLASSOLUTIONS Solaglas, inside triple-glazed windows in the pod, which was then tested for energy use against one built according to the 2006 build regulations.
The results showed the Passivehaus could save up to 72% more energy than the conventional building.
Dave Glendinning, the managing director said: “We’ve been manufacturing and installing PVC-U windows for the new-build and refurbishment markets with a 0.8 U-value windows for more than five years now, so we know exactly how effective they are in driving up energy efficiency in our homes.
“Despite the genuine demand in the market for low-energy solutions like our 0.8 windows and doors, independent testing such as this latest project by Nottingham University plays a vital role in encouraging even wider acceptance.”
The results of the test showed that a student living overnight in a Passivhaus pod used just 28% of the energy that was used by the student occupying the pod built to 2006 specifications.
