46 ENERGY HOUSE 2.0 SPOTLIGHT: EHOME2
projects that Barratt has ever undertaken. Along with Saint-Gobain and the University of Salford, we’re leading the way to test the impact that extreme temperatures caused by climate change could have. We have to reduce our reliance on fossil fuels, wherever they come from. With homes responsible for 16% of the UK’s carbon emissions, and with energy bills driving ination and putting pressure on households across the country, it’s vital to green the country’s housing stock. We need to innovate and test low carbon technologies to find solutions that make being green easy and cheap for everyone. We need to have enough suppliers, with products such as air source heat pumps, available at the scale and price required to meet demand. We need a skilled workforce to install and maintain this technology.
And we need the electricity grid to be ready to take the strain, with the capacity to cope as we shift to electricity. With the cost of living higher than for generations, we need consumers to come on the journey too. As we transition to the Future omes Standard, there is an urgent need to prepare people for what will be needed in a zero carbon world – and more sustainable living. Creating eHome2 will create a new blueprint for building homes at volume that are capable of operating at net zero carbon level, consuming far less water, and creating less waste. At times like this, with the cost of energy at a critical point, new solutions to create comfortable, efficient homes that will cost consumers far less to heat are essential.
COMMITTED TO LEADING SUSTAINABILITY To build a sustainable business that delivers value for shareholders, employees, partners and communities, we must act responsibly. Our approach to sustainability will help us to maximise long term value for communities, the environment and for the economy. To embed sustainability throughout Barratt, we are focused on the issues that matter to our customers, shareholders, employees and other key stakeholders, and have set long-term goals that define an ambitious future research and innovation road map.
arratt was the first national housebuilder to set science-based carbon reduction targets, along with a number of other sector-leading commitments across our supply chain. This is led by a commitment for all of the homes that we build to be zero carbon from 2030 and for Barratt to be net zero in our operations by .
Barratt is continuously working alongside the Future omes ub, and

challenging our supply chain to become more innovative and support the sector to achieve its sustainability goals. A key part of this is the Supply Chain Sustainability School, a transformative partnership in the construction sector that enables companies large and small to share learnings and drive change.
SPEEDING-UP CLIMATE CHANGE RESEARCH
The specially-built climate chamber at Energy House 2.0 is recreating temperatures ranging from to , as well as simulating wind, rain, snow and solar radiation. The chamber enables us to perform testing within a few months that would ordinarily take years. The data will help to inform how the wider housebuilding sector can design homes that are future-proof, while cutting bills for consumers. Weve begun the first set of research at eHome2, using 95 sensors and kilometres of cables to provide accurate data that will inform the construction sector around the world. Over the coming months, we’ll also have people staying in the home to provide a real world view of the technology and comfort levels in the homes. Just last week, we had a BBC reporter stay in the house the first real road test. So far, the eHome2 is performing as predicted. The first set of robust data will be released later this year.
The 18-month project will inform us to build net zero housing at scale, using off-site methods of construction and lower carbon products that reduce the impact on the planet.
BUILDING ON ZED HOUSE
The built environment accounts for of the UK’s carbon footprint. Achieving the Government’s carbon reduction targets will require a step-change in the design of new homes. Barratt, Saint- Gobain and The University of Salford are working together to create a blueprint
for future homes, including working in partnership to develop new low carbon products, such as the use of timber and render, instead of brick and block. The Energy House is the next step from Barratt’s zero carbon concept home, known as Zed House, to integrate new and improved products and technologies into eHome2. Zed House, built in collaboration with the University of Salford and innovation partners, reduced embodied carbon by 125%.
HARNESSING THE POWER OF RESEARCH AT ENERGY HOUSE 2.0
Professor Will Swan, director of Energy House Labs at the University of Salford comments: “The growing challenges of climate change and the cost of living crisis mean we need to consider how we build and operate our homes. Energy House Labs’ mission is to work with industry and policy makers to provide evidence for what works.” “Energy efficient, high performing homes can change people’s lives. The importance of this agenda is one of the main reasons behind the University of Salford’s major investment in Energy House 2.0, which is a critical piece of research infrastructure that can help us find solutions to these problems.” Richard Fitton, professor in building
performance at the University of Salford, adds: “The development of Energy House 2.0 has taken over six years and £16 million of funding.” He concludes: “Our work with some of
the largest housebuilders and product manufacturers in the UK will help to answer difficult questions about how we reach the zero carbon target in future housing. The facility will help us to stress test these buildings under extreme hot and cold climates, to provide data on energy efficiency and overheating in homes.”
