Technology and supply chain issues aren’t our biggest barrier to decarbonizing homes

Outdoor section of a heat pump

If you had enough money to commission a global architectural practice to design your home, you would also expect them to use sustainable design principles so that your home did not contribute to the number one crisis of our times…right? Apparently not according to anecdotal evidence, but who is to blame for this lack of demand, the client or the industry? And what does this say about our readiness to change our homes for the climate more generally? Where the focus was previously on getting political commitment and funding for decarbonizing the built environment, we need to focus now on helping the public make changes to their homes, and this is a lot harder than we think.

Many companies in residential property development, big and small, aren’t selling sustainable design as core to their product. I came across a marketing piece by a high-end design firm. They were pitching ‘resilient design’ – not regenerative or even sustainable design – but resilient. It was about giving wealthy clients a sense of security and control in a rapidly changing world where overheating, wildfires and power outages are increasingly common. An example from the pitch was that a home would have mechanical cooling most of the time, but natural ventilation would be built in, for use if the power went down. There’s nothing stopping the firm from designing a resilient AND sustainable, even regenerative, home. If budget is not a barrier, these luxury homes could easily have a positive impact for people and planet, but judging by the marketing content, sustainability must not be important to these clients.

I started thinking, who are these clients and how can they disregard their environmental and social responsibilities when they have the financial means to live up to both? But what if they’re just acting on the information that they have, in the world they live in? Common thinking about sustainable homes is that they are a niche and expensive product for lefties. But they don’t have to be expensive. Before the government-led Code for Sustainable Homes was scrapped in the UK in 2015, developers had already found ways to deliver high sustainability at an affordable cost. They also don’t have to be niche. Many cities and countries require high sustainability standards in their building codes. But what about the political element, is sustainable design still seen as a liberal solution, not just a good solution for the problems we all face?

This brings me to the odd social media debates currently raging about heat pumps and stovetops in the USA decarbonization agenda. You don’t have to dig deep to find conspiracy theories and a lot of rage about what people feel they are being ‘forced’ to do in their own homes. So what if people are just acting on the information that they have, in the world that they live in? Relatively rapidly our homes and appliances have become the site of a new kind of fortress building and cultural conflict. In cities and communities that are not in themselves resilient to the impacts of climate change, people with means will buy technologies to keep themselves comfortable. The home fortress in the 2020s is not one with a bomb shelter, but one with a power generator, mechanical cooling and storm shutters. People might not know that their air conditioning unit is making it harder for their neighbours to stay cool. They might feel that the carbon emissions created from their cooling system are an unfortunate but necessary cost to stay safe (in extreme heat) and comfortable (in moderate heat). So lack of information and better solutions are driving current household coping mechanisms, rather than active disregard for the negative impacts of certain technical solutions.    

We need to take people along on the journey to homes that are safe for occupants, fit for instability and climate friendly. We have to meet people where they are at not only in terms of money, but also motivation and knowledge. Last summer in the UK heatwave, I took part in some media outreach. On BBC Radio 5 Live, as the academic built environment ‘expert’ I was asked some basic questions about how design could help us stay cool in a heatwave. Reflecting on this now, I overestimated the general level of understanding. I think it’s not just me who has failed to listen and communicate in the right way. A lot of the available information is professionals talking to professionals, not the general public. If we expect people to make changes in their homes to deal with a changing climate, we need to understand the challenges and solutions that they’re currently working with. For example, we need to find out how different people currently cope with heatwaves and how this varies across properties and by age, gender and other factors. Then we can offer help on a scale from free advice on when to close windows all the way up to subsidies for a new heat pump.  

If the goals in the US Inflation Reduction Act and similar policies globally are going to be achieved, we need to learn important lessons about getting people to make changes to their homes (not only homeowners but also those who rent or live in public housing). Part of the reason why the UK Green Deal failed to work was a mismatch between the public’s knowledge and willingness to change their home and the government’s support package – specifically a shortfall in dependable suppliers and a lacklustre financing package. There is a huge need to invest in tailored information campaigns and skills development to widen the pool of trusted suppliers. Those of us working on climate change and the built environment need to be more understanding of the reasons that individuals resist changes in their home. It’s not just about publishing infographics, it’s about responding to the cultural, emotional and economic factors that shape the everyday experiences of living through a changing climate.

Connswater Community Greenway

New Connswater Greenway path, Belfast (October 2016) cc-by-sa/2.0 - © Albert Bridge - geograph.org.uk/p/5167207

Connswater Community Greenway (CCG) is an urban greenspace regeneration project in east Belfast transforming a blighted public space into a community asset. It consists of improvement works to a 9 km linear park connecting open spaces along the Connswater, Knock and Loop rivers. Alongside the recovery of neglected ecosystems, supporting residents’ health and wellbeing was a core objective of the regeneration project from the outset. The Greenway passes through 29 electoral wards, seven of which are within the top 25% most deprived wards in Northern Ireland. Community events and activities were organised throughout the project to create a sense of community and foster ownership of the greenspace, such as community clean-ups, volunteer gardening and walking groups.

The Greenway regeneration was a complex project with multiple partners and funding sources. The project was initiated from a 2005 Needs Analysis carried out by the East Belfast Partnership, and was later expanded to include significant flood alleviation measures after serious floods in 2007 and 2008.(1) The broad social purpose of the CCG is ambitious, as explained by a project evaluation:

‘In short, the Greenway exists to bring about dramatic and positive change to the physical environment and to people’s opportunities, health and lifestyles. People and communities which, for generations, have turned away from the dirty and neglected Connswater River system now have the opportunity to return and make the most of what has become a living landmark and a valuable, life-enhancing asset’ (2).

This project is featured as one of our healthy urban development case studies.

Top 10 Tips for Healthy New Communities

There’s a lot of guidance about designing healthy communities from public health and built environment professionals. For a change, I found it interesting to hear what Lord Richard Best called his ‘Top 10 Tips’ for designing healthy communities. Lord Best is ‘not a fan of major UK housebuilders’ because he feels their level of quality is not up to muster. So his example healthy development, Derwenthorpe, is led by the Joseph Rowntree Housing Trust, not a private developer.

Derwenthorpe on the Joseph Rowntree Housing Trust website

Lord Best has an informed position on designing and planning healthy communities based on his roles as Vice President of the Local Government Association and the Town & Country Planning Association, and co-chair of the All-Party Parliamentary Group on Housing and Care for Older People. He was also the CEO of the Joseph Rowntree Foundation (1988-2006).

Derwenthorpe is a new development of 489 ‘attractive, affordable, eco-friendly family homes in a digitally inclusive, mixed-tenure community’.1 It’s situated on the edge of an existing village, Osbaldwick, outside of York. Here’s what Lord Richard Best thinks makes this development healthy – couched as his ‘Top 10 Tips’:

Top 10 tips for healthy places (not in any order):

  1. Affordable housing – 40% are rented on secure tenancies
  2. Lifetime Homes Specification (fully accessible – good for all ages and conditions)
  3. Walkable for children – safe footpaths to school
  4. A ‘Sustrans’ accessible barrier-free track to the centre of York
  5. Residents get a free bus pass for a year or a loan to buy a bicycle
  6. Home zones (shared street space) where pedestrians have the right of way
  7. Substantial play spaces for children
  8. Sustainable Drainage Systems to avoid flooding (and water ingress into homes)
  9. Electric vehicle charging points on each home, one car parking spot per house and a car club
  10. Affordable heating and power – they have a Combined Heating and Power (CHP) system providing low cost energy for residents.

There are more details on the Joseph Rowntree website (below) with other features of this development that contribute to its sustainability and health credentials.

Auckland’s Wynyard Quarter renewal project

Given the long timespans of urban regeneration projects – spanning decades from initial plans to completion – I happened upon New Zealand’s largest renewal project at just the right time. Wynyard Quarter is well along its transformational journey from an industrial port into a very liveable and sustainable community.

In April 2018 it was already clear that Auckland’s planners have used fantastic public realm design and amenities to turn the port into a welcoming, walkable and fun neighbourhood. Having visited or worked on some of the world’s leading portside developments in Sweden, Hammarby, BO01 and Masthusen, I can see that this project will likely become a case study in sustainable design and development.

Kia Ora, Welcome to Wynyard Quarter sign

 

Walking from Auckland’s CBD you’re drawn west, past the ferry terminal and under the New Zealand’s Team America’s Cup Yacht at the Maritime Museum. You enter Wynyard Quarter by passing rows of luxury yachts and crossing a pedestrian drawbridge. As you approach, there are meanwhile uses, pocket parks and information boards drawing attention to the redevelopment. There will be 500 homes and 48,000 sq meters of commercial space in the central area of the quarter, much of which is starting to take shape now.

Visiting with my young family, we walked straight past the lovely waterside bars and restaurants to Silo Park. There is something here for all ages. A water feature, basketball net, and ‘under the sea’ themed playground were being enjoyed by children, teenagers and adults. Posters advertised outdoor concerts and an open-air cinema project against one of the silos. My favourite part was walking up the gantry, a bridge-like structure with multiple levels and partly covered in plants. It offered fantastic views of the emerging neighbourhood and the harbour bridge beyond.

The view from the gantry looking down on Hamer Street and the playground.

 

There are many planning frameworks setting out the ambitions and development requirements for Wynyard Quarter on the Panaku Development Auckland website. The project’s Sustainable Development Framework aims to move beyond zero net energy, water and waste impacts to a built environment that positively contributes energy and water and is ‘restorative’. Among other requirements, homes have a minimum target of 7 Homestar rating1 while commercial buildings will need to reach 5 Green Star rating2.

The city wants Wynyard Quarter to be a place where residents are proud of their contribution to a ‘more sustainable future’. This project has the most sophisticated monitoring system that I’ve ever seen for a masterplanning project to showcase its progress against sustainability goals, called Wynyard Quarter Smart.

Users of this online interactive tool can view information on a map of the neighbourhood or through navigating different theme areas, such as ‘Transport, Movement & Connectivity’. It’s fantastic to see that the project managers are reporting their progress throughout the renewal project.

This regeneration project is leading practice in many areas, incorporating smart systems and adopting ambitious goals for sustainability and health. Just reporting what I saw on my brief visit, here are some of the outstanding design and planning features that will support the developments’ goals for generations to come:

  • Infrastructure first: The housing development is just beginning but even early residents will be able to adopt healthy and sustainable behaviours such as walking or cycling because the street infrastructure is already in place to support this. There are also plenty of things to do in the area so that people will have reasons to interact and develop a sense of community.
  • Public realm design for all ages: People of all ages and abilities will find the parks and amenities around Silo Park to be fun and accessible. The gantry structure has a lift and stairs so wheelchair users or parents with buggies can see the outstanding views from the top deck.
  • Safe streets: The crossing points are clearly marked and level. The pavements are wide and allow plenty of space for pedestrians and cyclists.
  • Sustainable drainage: The sustainable drainage systems contribute to the landscape aesthetic and filters water.
  • Identity – marine and industrial heritage: This place has a very strong sense of identity that comes across through the design of the public realm – buoys floating in grass, the gantry, the ‘under the sea’ playground, the remnants of train tracks, and of course the silos.

Wynyard Quarter is a great place to visit, live or work. If you’re planning a similar project in your city, it would be well worth exploring their approach to sustainability and the incorporation of health and social wellbeing principles. It has already won an ‘Excellence on the Waterfront’ award in the Comprehensive Plans category in the USA.

Healthy place-making doesn’t have to cost extra

There is a common view amongst developers that designing and building for health and wellbeing objectives is more expensive than standard projects and that it doesn’t offer return on investment. I have recently written an article which summarises evidence from a range of organisations, including the Royal Institution of Chartered Surveyors and the Urban Land Institute, to counter these claims.

The built environment can provide access to physical activity at a range of scales, from transport and mobility infrastructure to provision of parks and even through building design. This is one of the most important features to consider given the cost of not getting this right. Public Health England reported that physical inactivity directly contributes to 1 in 6 deaths in the UK and costs £7.4 billion a year to business and wider society.(1) Through active design measures, a new masterplanned community of 5,700 homes in Texas has boosted physical activity of residents by 40-50 minutes a week.(2) BRE’s recent Design Protocol for Health + Mobility (in partnership with Arup, UCL and AREA Research) provides further information on integrating physical activity into masterplanning and transport infrastructure.(3)

The design of healthy homes and buildings has received significant attention from the development sector. Evidence from a Saint-Gobain commissioned survey demonstrated that 30% of the households surveyed would be willing to pay more for homes which do not compromise health.(4) By considering health impacts at the early stages of design, designers and developers can use integrated design solutions which do not cost extra and allow all homes to be safe and supportive of health and wellbeing. Healthy design should not just become a feature of high-value developments but should be delivered on all schemes. Developers using the Home Quality Mark and BREEAM will find that health and wellbeing is fully integrated into these standards and supports integrated design measures.(5)

Why measure urban sustainability and who should do it?

An international research network launched a report on their research of over 43 urban sustainability frameworks at a conference in London last Friday.(1) BRE’s sustainability standard for masterplans was included in the research and I was asked to present in a panel session about whether the quantity and variation of assessment frameworks was problematic or useful. The research showed that 34 out of the 43 frameworks were published between 2008 and 2013 leaving me to wonder why and how this focus on standards, benchmarking and assessment has grown so dramatically. Why are people measuring urban sustainability and who should be trusted with this task?

Standards serve multiple functions and depending on the nature of the standard, can have benefits for industry, government and citizens (or consumers if we’re talking about products or houses). The Top Dog standard for sustainable cities is considered to be ISO 37210:2014 Sustainable Development of Communities: Indicators for City Services and Quality of Life. A panel discussion in a Liveable Cities Singapore conference last October asked why this standard is used. Terry Hill, ISO President and former Chairman of Arup Group, said that it ‘is both “comprehensive” and “comparable”, enabling a method to compare cities as diverse as Mumbai and Manchester.’(2) Although comparison would only be possible if both cities had data for the same indicators (outside of the core indicators) and reported on these in a publicly accessible manner. Increasingly, I think cities will seek to publish these results in response to increased citizen demand for transparency from government. International comparisons are great for major cities that are looking to compete for talent and investment internationally. But that is not the only reason to measure urban sustainability.

Arguably, a more important reason to gather appropriate data and benchmark performance is for the city’s own use in checking whether its policies and services are meeting local needs. Sustainability indicators can be used by cities to inform and monitor policies and investment priorities. All of the following reasons are also relevant (taken from a scoping report on developing a UK Health Poverty Index (3) with some explanation from me in brackets):

  • ‘bidding for cash grants and special status
  • support and context for clinical governance [or governance of other services]
  • broad population health measurement [or measurement of other factors]
  • targeting services
  • resource allocation
  • examination of rural poverty [and urban]
  • monitoring and evaluation
  • performance management
  • visualisation of the extent and contrasts of deprivation in geographical areas using mapping and graphical analyses’ [or other factors]

When it comes to the scale of neighbourhoods, similar data and indicators are useful to understand and examine sustainability. BREEAM Communities (and its international competitors like LEED Neighbourhood Development) are focused on guiding the design of new development to be more sustainable. BREEAM Communities aims to improve the process of planning and designing a new community, including: involving the community and relevant stakeholders in design; considering sustainability holistically; and creating transparency about developer commitments on sustainability. It was odd to me that these frameworks were compared in the wider research with city sustainability indices like Siemens’ Green City Index which appear to be more of a marketing tool for the company’s services than a framework to help cities improve performance.

Many international consultancies and technology providers have introduced sustainability/smart city indices. I note that apart from IBM and Siemens, these are not listed in the research:

  • Sustainable Cities Index, ARCADIS
  • Green City Index, Siemens
  • Smart City Assessment Tool, IBM
  • City Resilience Framework, Arup (supported by Rockefeller 100 Resilient Cities)
  • Disaster Resilience Scorecard for cities, AECOM/IBM
  • New Resource Economy City Index, Accenture and Chinese Academy of Science (CAS)
  • Global Cities Index and Emerging Cities Outlook, ATKearney
  • Innovation Cities Index, 2thinknow

These indices or frameworks may fall on a spectrum of transparency and usability by city management. Judging by the press coverage of ARCADIS’s recently launched Sustainable Cities Index, these are powerful marketing and PR tools. And further inferring from the cost of investment in developing these indices, I imagine that they are also very useful for selling consulting services, infrastructure and technology.

As a conference panellist, I concluded that these frameworks have multiple purposes and are used by cities, planners, developers (etc.) for various reasons. Depending on the objective under question, multiplicity can be problematic or irrelevant. One delegate asked during a plenary session whether the research team still believes in urban sustainability frameworks. Following amusement from the audience and speakers, the response was generally supportive of the tools but encouraged international collaboration of independent organisations to look at reducing the number.

The Housing Standards Review will hinder the achievement of sustainable development

The long awaited Housing Standards Review Consultation was published today and we are none the wiser as to how government will achieve its aims without compromising the quality of new housing in the UK. The consultation showed:

Neighbourhoods taking developer contributions for sustainability

A ray of hope came forward on the topic of developers and sustainability in the PAS Neighbourhood Planning event yesterday in Bristol.  I was facilitating table discussions on the topic of how planners can support neighbourhood planning. I was keen to see what planners had to say about sustainability and neighbourhood plans. As it turns out, there are already examples of where communities have been vocal about their sustainability aspirations and they’ve been successful in getting developers to deliver them.

Neighbourhood planning and sustainability: mutually exclusive?

Popular opinion amongst planners and environmentalists is that neighbourhood planning and climate change don’t go together. But is that necessarily true and what does it mean for the rest of the principles behind localism and planning? In this post I look at choices and decision-making in the context of localism and sustainability. I think there is a way to nudge people into making the best decision for themselves and the planet.
