Simple improvements to building fabric, insulation, and ventilation have transformed the efficiency of the homes compared to traditional builds, with the properties 10 times as airtight as industry standards**. The homes are also fitted with photovoltaic solar panels, a battery, an electric vehicle charger, an air-source heat pump, a smart hot water tank, heat recovery ventilation and a wastewater heat recovery unit to minimise energy use and reduce emissions.
Due to the shift in reliance on fossil fuels to usage of electric-powered technology, the homes are also capable of delivering a 125% reduction in CO2 emissions compared to current standards.
The homes are built with a timber frame and the foundations have been formed using low-carbon concrete, meaning the embodied carbon has also been reduced from the outset.
Dave Smith, Managing Director, St. Modwen Homes, said: “With energy prices continuing to rise, creating energy-efficient homes that are affordable to build is more vital now than it ever has been.
“As an industry leader in using low-carbon modern methods of construction already, we have a responsibility to use this experience to prove that carbon negative houses can significantly cut energy bills and reduce emissions. Over the course of this year, we will be analysing the results of this latest trial to aid us in our objective to build these new homes at scale for the benefit of homeowners and the environment.”
