BACKGROUND

Salix Homes is a housing association based in Salford, Greater Manchester, owning over 8,000 homes.

Sustainability is a key focus for Salix Homes, and it’s committed to improving the energy efficiency of all its homes and buildings to benefit both its customers and the environment, aiming to become a carbon neutral organisation by 2038.

Salix Homes is building new homes in Salford and beyond and plans to build 300 new homes by 2025, which are high quality and energy efficient.

Its latest flagship scheme is Greenhaus – a highly sustainable development of 96 homes, which is being built on Chapel Street in Salford, an area which is currently undergoing significant investment as part of a wider regeneration project.

The nine-storey development, which is due to complete in March, has been built to Passivhaus Classic certified standard and is the largest Passivhaus certified affordable housing development in the North West.

Passivhaus is the gold standard for energy efficient buildings and construction, creating homes with high thermal comfort and improved air quality. Residents can benefit from a healthier living environment, reduced energy consumption and homes that are cheaper to heat and run.

FUNDING

Greenhaus is being delivered in partnership with the English Cities Fund (ECF) – a joint venture between nationwide placemaker Muse, Legal & General and Homes England, to bring together the public and private sector to transform urban areas. It’s supported by Salford City Council which has provided the land for the development.

Salix Homes is the housing association partner and is financing the project after securing funding with its banking partner NatWest. Grants have also been secured from Homes England and Greater Manchester Combined Authority (GMCA).

Greenhaus is part of ECF’s £1bn, 50-acre Salford Central transformation being delivered in partnership with Salford City Council, and will take the overall percentage of affordable homes delivered by ECF to 25% across the Chapel Street area of the masterplan.

The homes are being built by lead contractor Eric Wright Construction and were designed by architect Buttress.

ACTION

Delivering truly sustainable homes that are also affordable is a challenge, and high-spec homes with the energy saving credentials of Greenhaus are uncommon in the social housing sector.

Greenhaus represents a new era of high quality, sustainable and affordable homes which are better for the environment, support carbon reduction targets, and help reduce fuel poverty for residents.

It’s the first and largest development of its kind in the region, setting the benchmark for new-build, affordable and sustainable homes that are fit-for-the-future.

The one and two-bedroom homes will be available in a mix of tenures including social rent, affordable rent and rent-to-buy, giving more people the opportunity to live in homes in a desirable area, which are sustainable and affordable.

The sustainable features at Greenhaus include triple glazed windows, the latest insulation technology, improved ventilation and airtightness, air source heat pumps and publicly accessible electric vehicle charging points.

While the initial cost of building Passivhaus standard homes might be higher, Salix Homes has considered the long-term savings to be made on repairs and maintenance or complex and expensive retrofit solutions, as well as the financial and health benefits for residents.

IMPACT

Living in a Passivhaus-certified home, like Greenhaus, offers a more comfortable, healthier, environmentally friendly, and cost-effective living environment with benefits such as lower energy bills, improved indoor air quality and long-term sustainability.

Salford is the 18th most deprived area in the UK and the majority of Salix Homes customers are in receipt of welfare benefits. The new homes at Greenhaus will help reduce fuel poverty for residents, with the monthly cost of heating and hot water expected to be around £40, compared to £95 for a similar sized new-build home with a gas boiler.

Passivhaus properties offer a range of health benefits for residents and can reduce the impact on the NHS and the costs associated with illness related to poor quality housing and health inequality. Salford has the highest mortality rate from lung disease in England.

Passivhaus homes offer exceptional indoor air quality. The airtightness, thermal comfort and improved ventilation help protect against airborne pollutants, reduce the risk of illness associated with living in cold homes, and minimise the risk of damp, mould and condensation.

FUTURE PLANS

The first residents are expected to start moving in at Greenhaus from March 2024, and careful management of the homes once they’re occupied will help Salix Homes identify future learnings for Passivhaus developments.

Using the homes and their high-tech ‘green’ features correctly will be vital in ensuring the success of Greenhaus, and Salix Homes has planned a careful education and monitoring process for new residents.

All residents will receive a detailed user guide and instructional videos to help them get to grips with their new home and ensure it continually performs as it was designed to. Salix Homes has set up a specialist support team for its Passivhaus customers and has installed technology to remotely monitor the air quality and energy usage. Salix Homes will monitor the data, along with repairs and maintenance expenditure, alongside non-Passivhaus developments to help track the long-term benefits and identify lessons learned.

Salix Homes is also working in partnership with Salford University to track the health of new residents, in a bid to further understand the health benefits of living in Passivhaus property.

The experience of the partnership working at Greenhaus has paved the way for a second Passivhaus development in Salford, which is currently in the pipeline. It’ll be built to the same specification as Greenhaus, delivering a further 100 affordable homes that are fit-for-the future, contribute towards the battle against climate change and help to tackle the housing crisis.
