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

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.

Park 20|20

Park 20|20. Image: Delta Development 4

Park 20|20 is the first Cradle-to-Cradle ® (C2C) urban development project in the Netherlands, trailblazing design approaches that minimise resource consumption and support human health. The C2C approach is manifest in Park 20|20 through circular design, material health, and design for disassembly. The site includes an office tower, high density offices, hotel tower, athletic facilities, childcare facilities, greenhouses, and 9 hectares of public open space. The design is intended to create a closed-loop system where waste, energy and water are modelled after natural ecosystems.

As the first full-service C2C office park in the world, the development has pioneered business and legal models to support the transition from linear to circular economies. Known as a circular economy business model (CEBM), this approach seeks to ‘reduce resource use and waste within production, but also to extend product life cycles and employ strategies that allow the consumer to do more than buy, use and dispose.’(1) The project has also demonstrated the financial value of sustainable and healthy building design.

This project is featured as one of our healthy urban development case studies and this case study was written by Elizabeth Cooper and Helen Pineo.

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.

District heating can work in rural areas too

I had been under the impression that district heating is only suitable for urban areas. Today I learned that district heating can also be economically feasible in rural areas, particularly those areas off the main gas network.  This new knowledge is thanks to a Centre for Sustainable Energy event that I attended today. I went to understand more about how councillors and local planning authorities can support community-led energy projects.  Among other things, I ended up learning how to assess whether a particular village has enough local woodland to support a biomass district heating scheme.

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.

Monitoring on-site renewable requirements

The Merton rule is old hat and even ‘Merton plus’ is becoming yesterday’s solution.  Planning requirements that are intended to reduce the carbon emissions of a development need to begin with the energy hierarchy, prioritising decentralised energy before insisting on 10-25% reductions from on-site renewable energy installations.  If the policy does not allow for flexibility with the on-site renewable contribution it could reduce the overall CO2 savings.  Nevertheless, authorities still have Merton-type policies – and considering the time it takes to change planning policies, they may be with us for some time.

LB Westminster planners hosted an event on monitoring renewable energy planning policies in late July.  Two ex-Merton officers, Adrian Hewitt and Ed Cotterill, presented an automated energy monitoring system that they have developed.  Here’s how it works:  There’s a data logging box installed on-site that measures the productivity of renewable energy installations.  This information is automatically sent off to a network.  A planning officer or developer can log-in to the network and see how the renewable energy installation is doing.  Planners or monitoring officers could keep track of compliance with the carbon reduction policies for all developments that had on-site technologies.  As you might expect, this recently developed technology has exposed some underperforming energy installations.

It’s obvious if you think about it.  Calculations are done using estimates and a technology is approved by the planning service (this is not a clean-cut process).  A building is then fitted with PV panels or a wind turbine and the job is done.  But what if the PV panel wasn’t properly connected or the wind hardly blows in that area?

Carbon is invisible, money is tangible

The recently abolished Sustainable Development Commission held a launch event for their report on empowering communities to improve their neighbourhoods a few weeks ago.  I went along because I needed some convincing to support the Big Society concept and how it might work for sustainability.  I’m not at all convinced, but after some time to reflect over my summer holiday I think I’m finally able to put my thoughts into words.  Many planners and sustainability professionals will agree that community groups are more likely to form and raise their voice on issues they oppose, rather than organising themselves to build schools and local energy schemes.

Phillip Blond, Director of ResPublica, spoke at the SDC launch event about the ‘increasingly fragmented’ nature of our society and how people are not associating.  He spoke about how it’s problematic to get people to form groups on lots of separate issues like crime and health because it leads to disaggregated communities.  Not everybody in the audience agreed with this but I found it very thought provoking.  In terms of the environment, he said that climate change is the only topic on the environment agenda, but people just don’t get it.  Carbon is invisible: “have you ever seen any?” Continue reading “Carbon is invisible, money is tangible”
