Trivselhus by Esh receives airtight seal of approval in independent building regulations tests

Posted 11 November 2016

Luxury housing developer TrivseIhus by Esh has shown itself to be leading the way for “green” home design in the North of England after recent tests showed a sample of homes to suffer less than half the “air leakage” required under building regulations on average.

Air tightness tests refer to the uncontrolled loss of air from a building through gaps, holes and cracks in the fabric of the building – typically identified as draughts. Achieving a good level of airtightness (and low air leakage) reflects the quality of a building’s construction and is a key factor in determining the energy efficiency of a building.

Modern building regulations require that developers prove the air tightness of their homes through independent tests on a sample of their homes. Under Part L of the England and Wales Building Regulations – The Conservation of Fuel and Power, the maximum air permeability of homes must be no more than 10 m3/(m2h)@50pa, although results of 5 m3/(m2.h)@50Pa are more common

In recent tests performed by independent specialists Stroma Tech, a sample of Trivselhus by Esh homes averaged 1.96m3.h-.m@50pa, indicating that they are more than twice as air-tight as the average UK home.

To put this into context, the sample’s readings were comparable to the airtightness found on industrial freezers.

On the results of the tests, Rob Coxon of Stroma Tech, said:

“These figures are some of the most impressive we have seen from residential housing developments. Air leakage is a significant cause of heat loss in the home, typically placing increased demands on energy sources such as gas and electricity.

“By working to improve airtightness, developers can help to reduce the environmental and financial cost of new homes significantly. We welcome the work done by Trivselhus by Esh on building homes that place a premium on insulation and energy-saving features.

As the first housing developer to create multiple-plot low-energy homes of this kind in the North of England, Trivselhus by Esh sites at Brampton, Wetheral and Hexham are well under way.

The Trivselhus by Esh brand – a partnership between UK construction firm, Esh, and Swedish building company, Trivselhus, has already sold a number of plots off plan thanks to the distinctive design and innovative energy-saving features.

Sales and Marketing Director at Trivselhus by Esh, Colin Willetts, says:

“The combination of Swedish open-plan spaces, eye-catching architecture and energy-efficient technologies makes our developments somewhat unique in the North East and Cumbria. Not only are our properties extremely well insulated, they also feature solar panels, air source heat pumps and mechanical ventilation systems with heat recovery – features that can lead to a marked reduction in dependency on mains energy supplies.

“We are delighted to have already taken a number of reservations on plots at our developments and received interest from buyers all over the country. We recently completed our show-home at Hexham Gate and already we are seeing a real appetite for this kind of home in the region.”
