Water Efficiency and Reuse in Housing

The Good Homes Alliance (GHA), in partnership with industry leaders and supported by the Enabling Water Smart Communities project and the UK Water Efficiency Collaborative Fund, has launched a new publication – ‘Water Efficiency and Reuse in Housing: Design Guide for a Changing Climate’.

About the guide

Developed for architects, developers, planners, and housing associations, the publication, authored and edited by architect Pollard Thomas Edwards (PTE), provides case studies, best practice guidance, and industry insight to respond to the urgent need for ‘water-smart’ homes due to mounting water stress in the UK.

The guide offers practical, evidence-based design strategies to help housing professionals deliver on emerging policy and environmental imperatives. It includes model specifications for fittings, layout, and reuse systems – all geared toward meeting or exceeding the government’s 110 litres per person per day target. With the Environment Act and DEFRA consultations set to tighten regulations, the publication arrives at a critical moment.

As water scarcity begins to stall planning in regions like Sussex and Cambridgeshire, the guide moves beyond policy rhetoric and provides workable design and engineering approaches that can be applied today. It follows Waterwise’s established water neutrality hierarchy: reduce, reuse, offset – ensuring developers are equipped to respond to local and national demands.

Nicci Russell, CEO, Waterwise

“Water scarcity is one of the UK’s most urgent challenges. Our water supply can no longer meet rising demand. As a society, we’ve doubled our water usage over the past 60 years, and the population has increased by 16 million since 1960. So there are more of us than ever before, we’re using more than our fair share of water – and we’ve caused a climate emergency, so there’s less water available when we need it! To get our water use down to the lower levels we need, we will need ALL homes and businesses to be water-efficient – not just the kit in them, but also the people using it! This guide is a vital step forwards in that goal.”

Six detailed case studies are central to the guide. They showcase water-efficient housing in action at a variety of scales, from luxury developments in London to high-performance council housing and zero-carbon pilot homes. These examples demonstrate a range of approaches – from smart monitoring and fittings-based reductions to rainwater harvesting and community-scale greywater recycling.

In tandem, the guide explores the broader cultural and behavioural barriers to efficient water use, featuring commentaries from experts at the Chartered Institution of Water and Environmental Management (CIWEM), PTE, Watergate and Waterwise.

This is the second publication in GHA’s Designing for a Changing Climate series, following its well-received 2023 shading guide. As with its sister title, the new water guide aims to drive change in design practice, policy, and supply chains alike.

Andrew Tucker, Water Demand Reduction Manager, Thames Water

“Water companies have a huge role providing world-class drinking quality water to every house, every day.  The growth agenda is driving for more homes, whilst a changing climate and environmental targets will reduce water availability.  This challenge needs strong policy and clear guidance, so that future housing development is part of the solution and not adding to the problem. This document can help all players plan and build water efficient homes.”

Gareth Thomas, Commercial Director, Watergate

“Housebuilders and developers know they need to deliver water-efficient homes – but knowing where to start isn’t always easy. This guide bridges that gap. With ambitious new build targets ahead, we have a golden opportunity to design a generation of homes that are water-wise from day one, using the best of today’s smart tech and harvesting solutions.”

Shading for housing

Download the guide 

The Good Homes Alliance (GHA) and the British Blind and Shutter Association (BBSA) have launched a new design guide on shading for housing, seeking to embed a new culture – among building makers of all stripes – in which shading is central to a building’s design and built-in from the start.

The work has been led by an experienced team at award-winning architect Pollard Thomas Edwards (PTE), including sustainability lead Tom Dollard, author of ‘Designed to Perform’, Passivhaus designer Joseba Perez, and sustainable design specialist Raffaella Corrieri.

The guide was launched at a popular in-person event on 9th November at PTE’s offices at Diespeker Wharf in London, with talks from the wider project team which includes renowned engineering firm Max FordhamRajat Gupta, Professor of Sustainable Architecture and Climate Change at Oxford Brookes University, and construction consultants, Martin Arnold.

Why is the guide needed? Future proofing and climate resilience

As global temperatures continue to rise, so does the risk of buildings overheating. A recent study1 shows that by the middle of the 2030s, 90% of the UK housing stock will suffer from overheating. Simply put, our built environment – designed for dampness, breeze, rain and mild heat – is in no fit state to shelter us from this changing climate.

Currently in the UK, buildings are not required to pass the overheating criteria using future weather files to comply with the Building Regulations. Modelling using predicted future weather data has shown that buildings designed with shading products built-in from the start are less likely to overheat in the future than those that aren’t.

This guide calls for a new design culture in the UK. A design culture in which the everyday specification of shading products on domestic buildings – or the designing for shading from the start – is second nature among developers, housebuilders, architects and consultants.

The public too, buyers and tenants alike, should be well-versed in the benefits that shading products bring, in terms of reduced running costs, improved comfort and general wellbeing. The guide provides a shading ‘cheat sheet’ focused on the practicalities of adapting to holistic shading design.

What is in the guide?

A product section provides detailed information to help users to select the right product for a building’s shading needs. Each product page features a brief description, a table detailing its functionality, an in-situ product photograph, a ‘performance web’ visualising a product’s strengths and weaknesses and, where relevant, an architect’s comment on a product’s added value.

The guide also provides a short history of shading design, explores UK-specific design challenges and wraps up with best practice advice.

The guidance is applicable to both new build and retrofit projects, and aimed at a range of stakeholders including architects, local authorities, planners, housing associations, developers, and policy makers.

Who has supported the guide?

Development of the guide has been supported by:

Ballymore – See case studies

Caribbean Blinds – See image gallery

Guthrie Douglas – See project gallery

Louvolite – See style blog

A steering group* of industry experts and stakeholders from across the sector has supported the development of the guide, with representatives from Architype, Greater Cambridge Shared Planning Service, CIBSE, ECD Architects, NDM Heath, OX Place, Sovereign, TOWN and Urban Light Surveyors.

Quotes

“Since 2014, when Good Homes Alliance published ‘Preventing Overheating’ an evidence-based report on overheating and mitigation, we have worked on guidance and tools to mitigate overheating in homes.  In 2019, we launched our tool and guidance to identify and mitigate overheating risks for new homes, followed by a version for retrofit and existing homes in 2022. This latest guidance expands on applicable strategies, seeking to influence decision making at an early stage, and provide the industry with the tools and knowledge to identify and integrate shading solutions as part of a holistic approach to resilience and aesthetics appropriate for our climate challenge.”

Lynne Sullivan OBE, Chair, Good Homes Alliance

“A guide like this, researched and prepared by a multi-disciplinary team from the built environment and the solar shading industry, is long overdue. The BBSA is proud to have been involved in developing such a practical and useful guide to help make our homes more energy efficient and comfortable, now and in the future.”

Andrew Chalk, Director of Operations, BBSA

“Our homes are overheating, and we simply can’t afford to address this with increasing mechanical ventilation or air conditioning. It is clear that shading must become a central component of design approaches to prevent increased overheating and unnecessary carbon emissions. I hope this guide goes some way to enable this necessary change in design culture, by increasing our knowledge and awareness of the range of shading types available, to help us design beautiful shading solutions that deliver improved outcomes for people and planet.”

Tom Dollard, Partner – Sustainability and Innovation, Pollard Thomas Edwards

“It is essential that the design of buildings prioritises future-proofing and protecting users from the effects of the climate emergency. As the earth’s climate warms and the thermal performance of buildings improves, overheating mitigation becomes more about keeping heat out of buildings, rather than in. Solar shading has a critical role to play in this. We hope this shading design guide will illustrate the opportunities for incorporating shading in buildings and help building owners, designers, and developers to choose the best option for their project.”

Kai Salman-Lord, Senior Building Performance Modeller, Max Fordham LLP

“Research studies have often raised the need for integrating shading in our homes for building long-term resilience against heat. For the first time, this report provides compressive evidence-based guidance on the performance of different shading products, to enable building design team and housing providers incorporate shading solutions for future-proofing new builds and retrofits.”

Professor Rajat Gupta, Professor of Sustainable Architecture and Climate Change, Oxford Brookes University

“The threat to life due to homes overheating in summer is rapidly overtaking the danger posed by lack of heating in winter. Solar shading can be the silver-bullet, regulating temperature whilst saving energy, and insulating properties in the winter too; but only if it is well-designed and not an afterthought. This guide is a great starting point for any specifier asking themselves how to achieve that.”

Andrew Kitching, Managing Director, Guthrie Douglas

“Climate change is no secret, and the issue of overheating will only become more apparent as time goes on. Whilst the solution to combat this problem already exists to an extent, solar shading products have an important part to play in helping our climate journey and need to be designed and incorporated from the outset.

Every measure needs to be taken to address the installation of solar shading during the design stage of any building in order to ensure its energy efficiency is at its highest, preventing the increasing number of homes from turning into unhabitable ‘greenhouses’ and ultimately cooling our planet.

This guide will go a long way in clearly setting out the ways in which the housebuilding industry can work together to minimise and mitigate overheating risk in new and existing homes. We’re proud to be helping raise awareness of this ever-growing and very real issue.”

Wednesday 8th March, 13:30-14:15, Buildings Stage – Minimising and mitigating overheating risk in homes

UK homes are increasingly at risk of overheating, which can lead to uncomfortable indoor environments for homeowners and residents. Overheating can be caused by poor housing design, uncontrolled solar gain, inadequate shading, and insufficient summer ventilation. Contextual factors such as external noise and security concerns can also restrict opportunities for natural ventilation. Hear from industry experts on the assessment tools, best practice design approaches and solutions available to minimise and mitigate overheating risk in homes.

Wednesday 8th March, 15:30-16:15, Buildings Stage – Using monitoring to understand net zero homes

By the middle of this century the world has to reduce emissions to as close to zero as possible. This pursuit to Net Zero requires the UK to virtually eliminate emissions from the built environment and with ~28m homes currently contributing 18% of all carbon emissions, the UK has a big challenge ahead.

With challenge comes opportunity. This seminar session, delivered by the Building Performance Network, will demonstrate how taking a systems, not piecemeal, approach to building performance evaluation will help to really understand net zero homes. Using data will truly enable you to set meaningful targets and implement robust strategies for energy efficiency in homes, both old and new.

Case Study

Penderi Retrofit Project

A flagship shared energy retrofit scheme in a Swansea development is enabling homes to generate, store, share, and manage energy generated from solar panels across the site, following the installation of ground-breaking new energy management technology.

The Penderi Energy Project is a flagship scheme being delivered in collaboration between energy tech company and GHA/BPN member Sero, affordable homes developer Pobl Living and contractor Everwarm. The project will see 650 social rented homes in a Swansea community generating as much as 60% of their total electricity requirements, lowering energy bills for residents by up to 30% and reducing carbon emissions by as much as 350 tones per year.

All homes across the development are being fitted with batteries and solar panels (where their roof is appropriate) that on their own provide almost 20% improvement on energy efficiency than standard building regulations.

In addition to green technologies, the homes are also being fitted with an intelligent heating management system, run by a hub called the Building Energy Engine (BEE). This allows the monitoring, measurement, and control of energy usage as well as the measurement of the internal environment of the home. Used in conjunction with the Sero Life App, residents are able to measure and manage their own energy usage, as well as forecast future energy requirements of the property based on past usage.

These state-of-the-art measurement technologies are essential components in the energy sharing scheme and will play a crucial role in future energy and cost savings.

Project manager at Sero, Anne-Marie Ratcliffe said:

“What is most innovative and unique about this project is the management of the energy being generated and the sharing scheme. The technology we have created enables everyone in the development to benefit, whether they have panels on their roofs or not. Every resident will see a reduction in their energy bills and usage.This is incredibly important given both the current climate crisis and the cost-of-living crisis.”

Pobl director of regeneration, Solitaire Pritchard added:

“The technology being used for this project allows us to not only be a responsible business when it comes to addressing climate change but also help to protect our customers from the volatile peaks and troughs that we are currently experiencing in the market.”

The energy generated from the solar panels is evenly distributed across all homes in the development and allows them to participate in a unique shared billing scheme. It also means that residents can use the energy stored at the most appropriate and most expensive times, rather than drawing energy from the grid. This energy efficiency usage allows residents to experience significant reductions on their energy bills. With one resident reporting halving the amount of money she puts in her meter each week.

The system is currently installed in 400 of the 650 homes across the community, and these are already reducing the amount of energy being drawn from the national grid. Any excess power produced by the solar panels and not stored in batteries, will be fed back into the network grid, benefitting from export tariffs when doing so.

The retrofit project, which is planned to be completed by July 2023, is helping to reduce the amount of carbon being produced by the community as a whole and by individuals within their homes, while also providing up to 60% of the community’s energy needs at any one time.

The blueprint for this retrofit project is already being used across a series of projects totaling 5000 homes in Wales and across several Registered Social landlords. This project is still in its infancy but following its success is likely to be duplicated and rolled out in more communities and developments in both Wales and the UK.

Lessons learned from the project will inform the wider spread of renewable energy technology in thousands of homes throughout the Swansea Bay City Region, as part of the £1.3bn City Deal, in the Homes as Power Stations project – subject to the approval of the UK and Welsh Governments. This would see energy efficiency technology retrofitted to 7000 homes with a further 3300 new build homes also benefitting as part of the project, which is led by Neath Port Talbot council.
