Uncomfortable home truths: Why Britain urgently needs a low carbon heat strategy

Posted on by janet.crompton



A new report backed by MPs and launched by Minister for Climate Change Lord Duncan on 15 October 2019, calls for an urgent Green Heat Roadmap by 2020 to scale low carbon heating technologies and help Britain’s homeowners access the advice they need to take smarter greener choices on heating their homes.  The year-long study by UK think-tank Policy Connect warns that the UK will miss its 2050 net-zero climate target “unless radical changes in housing policy, energy policy and climate policy are prioritised”. Dr Colin Nolden was at the launch on behalf of the Cabot Institute for the Environment and blogs here on the most interesting highlights of the report and questions raised.

———————————-

Policy Connect had invited a range of industry, policy, academic and civil society representatives to the launch of their Uncomfortable Home Truths report. The keynote, no less than Lord Duncan of Springbank, Minister for Climate Change, and the high-level panel consisting of Maxine Frerk, Grid Edge Policy (Chair), Alan Brown MP, House of Commons (SNP), Dr Alan Whitehead MP, House of Commons (Labour), Dhara Vyas, Citizens Advice, Adam Turk, BAXI Heating (sponsor) and Mike Foster, EUA (Energy & Utilities Alliance), (sponsor), had been briefed to answer tough questions from the crowd given the UK’s poor track record in the area of heat and home decarbonisation.

The event started with an introduction by Jonathan Shaw, Chief Executive of Policy Connect, who introduced the panel and officially launched the report. Uncomfortable Home Truths is the third report of the Future Gas Series, the first two of which focused on low-carbon gas options. This last report of the series shifts the focus from particular technologies and vectors towards heating, households and consumers. Jonathan subsequently introduced the keynote speaker Lord Duncan of Springbank, Minister for Climate Change.

Lord Duncan supported the publication of this report as timely and relevant especially in relation to the heat policy roadmap that government intends to publish in 2020. He stressed the importance of a cultural shift which needs to take place to start addressing the issue of heat at household and consumer level. He was adamant that the government was aligning its policies and strategies with its zero-carbon target according to the Committee on Climate Change and guided by science and policy. In this context he bemoaned the drive by some country representatives to put into question the targets of the Paris Agreement on Climate Change which he had witnessed as the UK’s key representative at the run-up to COP25 in Chile. The 2020 roadmap will report on the decisions which will need to be taken in homes and in technology networks, ranging from heat pumps to hydrogen and low-carbon electricity to support their decarbonisation. It requires cross-party support while depending on more research and learning from successful examples in other European countries.

Although Lord Duncan suggested that ‘it’s easier to decarbonise a power plant than a terraced house’, he told the audience to take encouragement from the fuel shift from coal towards gas starting half a century ago. But in this context he once again stressed the cultural shift which needs to go hand-in-hand with government commitment and technological progression, using the example of TV-chefs shunning electric hobs as an indication of our cultural affinity for gas. As long as heating and cooking are framed around fossil fuels, there is little space in the cultural imagination to encourage a shift towards more sustainable energy sources.

Among the questions following the keynote, one quizzed Lord Duncan about the process and politics of outsourcing carbon emissions. Lord Duncan stressed his support of Border Carbon Adjustments compliant with EU and global carbon policy ‘in lock-step with our partners’ to ensure that carbon emissions are not simply exported, which appears to support the carbon club concept. Another question targeted the UK’s favourable regulatory environment that has been created around gas, which has resulted in the EU’s lowest gas prices, while electricity prices are highest in Europe, due, among other things, to Climate Change Levies, which do not apply to gas, increasing by 46% on 1 April 2019. Lord Duncan pointed towards the ongoing review of policies ahead of the publication of the 2020 heat roadmap which will hopefully take a more vector- and technology-neutral approach. A subsequent rebuttal by a Committee on Climate Change (CCC) representative stressed the CCCs recommendation to balance policy cost between gas and electricity as on average only 20,000 heat pumps are sold in the UK every year (compared to 7 times as many in Sweden) yet the Renewable Heat Incentive is about to be terminated without an adequate replacement to support the diffusion of low-carbon electric heating technologies.

Lord Duncan stressed the need to create a simple ‘road’ which does not fall with changes in policy and once again emphasized the need for a cross-party road to support the creation of a low-carbon heating pathway. A UKERC representative asked about the government approach to real-world data as opposed to modelling exercises and their support for collaborative research projects as both modelling and competitive approaches have failed, especially in relation to Carbon Capture and Storage. Lord Duncan responded that the UK is already collaborating with Denmark and Norway on CCS and that more money is being invested into scalable and replicable demonstrators.

Following an admission wrapped in metaphors that a change in government might be around the corner and that roadmaps need to outlast such changes, Lord Duncan departed to make way for Joanna Furtado, lead author of the Policy Connect report. She gave a very concise overview of the main findings and recommendations in the report:

  • The 80% 2050 carbon emission reduction target relative to 1990 already required over 20,000 households to switch to low-carbon heating every week between 2025 and 2050. The zero-carbon target requires even more rapid decarbonisation yet the most successful policy constellations to date have only succeeded in encouraging 2,000 households to switch to low-carbon heating every week.
  • This emphasizes the importance of households and citizens but many barriers to their engagement persist such as privacy issues, disruption associated with implementation, uncertainly, low priority, lack of awareness and confusion around best approaches, opportunities, regulations and support.
  • Despite the focus on households, large-scale rollout also requires the development of supply chains so at-scale demonstrations need to go hand-in-hand with protection and engagement of households by increasing the visibility of successful approaches. Community-led and local approaches have an important role to play but better monitoring is required to differentiate between more and less successful approaches.
  • Protection needs to be changed to facilitate the inclusion of innovative technologies which are rarely covered while installers need to be trained to build confidence in their installations.
  • Regional intermediaries, such as those in Scotland and Wales, need to be established to coordinate these efforts locally while at national level a central delivery body such as the one established for the 2020 Olympics in London needs to coordinate the actions of the regional intermediaries.
  • Ultimately, social aspects are critical to the delivery of low-carbon heat, ranging from the central delivery body through regional intermediaries down to households and citizens.

Chaired by Maxine Frerk of Grid Edge Policy, the panel discussion kicked off with Alan Brown who stressed the urgency of the heating decarbonisation issue as encapsulated by Greta Thunberg and Extinction Rebellion and the need to operationalize the climate emergency into actions. He called for innovation in the gas grid in line with cautions Health and Safety Regulation alterations. Costs also need to be socialised to ensure that the low-carbon transition does not increase fuel poverty. His final point stressed the need reorganize government to make climate change and decarbonisation a number 1 priority.

Dr Alan Whitehead, who has been involved with the APPCCG from the beginning, emphasized how discussions around heat decarbonisation have progressed significantly in recent years and especially since the publication of the first report of this series. He suggested that the newest report writes the government roadmap for them. In relation to the wider context of decarbonising heat, Alan Whitehead encouraged a mainstreaming of heating literacy similar to the growing awareness of plastic. He also stressed how far the UK is lagging behind compared to other countries and this will be reflected in upcoming policies and roadmaps. As his final point Alan Whitehead cautioned that the low-intrusion option of gas-boiler upgrades from biomethane to hydrogen ignores the fact that greater change is necessary for the achievement of the zero-carbon target although he conceded that customer acceptance of gas engineer intervention appears to be high.

Dhara Vyas presented Citizens Advice perspective by stressing the importance of the citizen-consumer focus. Their research has revealed a lack of understanding among landlords and tenants of the rules and regulations that govern heat. She suggested that engagement with the public from the outset is essential to protect consumers as people are not sufficiently engaged with heating and energy in general. Even for experts it is very difficult to navigate all aspects of energy due to the high transaction costs associated with engagement to enable a transition on the scale required by government targets.

Finally, representatives of the two sponsors BAXI and the Energy & Utility Alliance made a rallying call for the transition of the gas grid towards hydrogen. Adam Turk emphasized the need to legislate and innovate appropriately to ensure that the 84% of households that are connected to the gas grid can receive upgrades to their boilers to make them hydrogen ready. Similarly, Mike Foster suggested that such an upgrade now takes less than 1 hour and that the gas industry already engages around 2 million consumers a year. Both suggested that the gas industry is well placed to put consumers at the heart of action. They were supported by several members of the audience who pointed towards the 150,000 trained gas service engineers and the ongoing distribution infrastructure upgrades towards plastic piping which facilitate a transition towards hydrogen. Other members of the audience, on the other hand, placed more emphasis on energy efficiency and the question of trust.

Sponsorship of the Institution of Gas Engineers & Managers, EUC (Energy & Utility Alliance) and BAXI Heating was evident in the title Future Gas Series and support for hydrogen and ‘minimal homeowner disruption’ boiler conversion to support this vector shift among members of the audience was evident. Nevertheless, several panel members, members of the audience and, above all, Lord Duncan of Springbank, stressed the need to consider a wider range of options to achieve the zero-carbon target. Electrification and heat pumps in particular were the most prominent among these options. Energy efficiency and reductions in energy demand, as is usual at such events, barely received a mention. I guess it’s difficult to cut a ribbon when there’s less of something as opposed to something new and shiny?

Grey Britain: Misery, urbanism & neuroaesthetics

Posted on by janet.crompton

“We have created a Star Wars civilization, with Stone Age emotions. We thrash about and are a danger to ourselves and the rest of life.” – E.O. Wilson, The Social Conquest of the Earth (2012).

 

In a previous article I have discussed the use of simple patterns to interpret the complexity of nature and the human interface with it. Here, I will illustrate this concept on a larger canvas, discussing this interface, between nature and social systems, more thoroughly. This final article, in the series on inter-disciplinary work I have written for the University of Bristol Cabot Institute for the Environment, is partially motivated by my personal interest in the cycle of urbanism, the associated architecture and concepts. It is also motivated by a project I followed closely during a past flirtation with living and working in London and the comparable changes I see happening around me in Bristol, where I currently live and work.
Billboard #1 from London is Changing project (source: londonischanging.org).

‘London is Changing’ was an arts project undertaken by Dr. Rebecca Ross at Central St. Martins in 2015. It highlighted the effects of economic policy in the capital by displaying the stories of individuals relocating in, out and within the capital, out of choice and necessity, on billboards around the city. On one level, this project introduced me to the plight of individuals whose movements are determined by expropriation, economic policy or various other processes largely beyond their control. On another level, it gave me an insight into the emotional response this change in environment can invoke in those undertaking such change.

Indeed, as modern society has ridden the wave of an economy of concentrated wealth creation the transient notion of moving somewhere new for education or employment has become a perceived norm. Yet, there is a polarising undercurrent to this wave, in which generations of individuals face the prospect of never being able to afford to permanently root themselves to the environment, where the terms ‘gentrification’ and ‘displacement’ have come to define the nature of settlement and where our demand, and in some cases, expectation, of a ‘home’ is placing an unsustainable strain on ourselves, materials, space and the environment at large. Be it due to social, economic or environmental causes, these trends are effectively driving people further from their familiar habitat and immediate social connections, which leads to social destabilisation – a key contributing factor of societal vulnerability.

The inter-environmental patterns of displacement and resettlement are as intriguing as they are worrying. Similarly, a concept related to this physical displacement, the notion of intra-environmental displacement is one which can set the foundations of an unstable social system. This is to say, an emotional displacement characterised by a detachment created through rapid physical change of the surrounding environment, one that can enhance the disconnection between people and their environment and, in some cases; other people. Notionally linked to gentrification, urban renewal or regeneration is part of the cycle of urbanisation and whilst it does not immediately or physically displace a person from the environment, it’s effects are becoming more documented and this is to a largely negative fanfare.
Drawing on the personal experience of having worked and socialised with residents of the recently regenerated Heygate, Aylesbury, the (old) south Kilburn Estates in London and coupling this with my academic work and interest, I have given great consideration to the phenomena of intra-environmental connection and disconnection. Indeed, the initial results of my own research with flooding and social systems is conspecific with the kind of systematic social change discussed in this article, differing only in temporal scale, whereby enhanced social interaction has the potential to negate the detrimental effects of uninvited change, be it rapid onset as is the case with a flood inundation or prolonged onset via environmental redevelopment, to the structure of the social system. Observing the changes currently taking place in Bristol, at Temple Quarter and along the southern bank of the Avon, I feel urgency in the need to communicate the detrimental potential of poor foresight, as well as the positive potential of implementing new approaches, in urban development and renewal of any kind.

The Biophilic Hypothesis, P2P Urbanism & Neuroasthetics

Biophilia is a term that was first introduced by psychoanalyst Erich Fromm in 1973’s ‘The anatomy of human destructiveness’ to describe a “passionate love of life and all that is alive”. One only needs to pause for a moment to consider this term in relation to current global affairs to concur with the author in his estimation that it is distinctly lacking from the zeitgeist of our time.
Biologist and foremost proponent of sociobiology, E.O. Wilson later utilised the term to describe “the urge to affiliate with other forms of life”. Wilson has suggested that this urge, to affiliate and connect with one another, other species and the natural environment at large is a biological necessity in the continuation of our species. Furthermore, Wilson has also suggested that a true or complete biophilic environment would be one that provides an appropriate habitat and home whilst also naturally connecting the human to the environment via the promotion of natural social and environmental connections. The biophilic principle has acted as the inspiration and catalyst for a divergence in thinking related to modern urban theory.

The structure of life I have described in buildings is deeply and inextricably connected with the human person and with the innermost nature of human feeling

 – Christopher Alexander, Nature of Order (1963).
Nikos Salingaros and Christopher Alexander, leading design theorists, polymaths and ardent critics of modern architectural design, have suggested in their works that a historic shift in urban architectural design accompanying post-world war II urbanisation, based on a supposed ideal concept of order over function or form, has become a pseudo-standard leading to a widespread loss of environmental identity at the human scale within the built environment initially through sprawl and latterly grand-scale, monoculture.
This loss of identity occurs through a number of routes, aesthetically via design or use of distally sourced materials, unclear structural purpose via desired use of the structure superseding local need or location via dramatic replacement of a visually recognisable building of historic or social importance. Salingaros and Alexander have suggested that this loss of identity lends itself to a loss of societal orientation and has partially or fully led to the proliferation of all things from social polarisation to the increasing rates of mental ill health in urbanised areas.
Drawing influence from Wilson’s concept of concilience, Salingaros has proposed many alternative solutions for the reconciliation of urban development at the human scale, solutions which are based on rigour with a view to addressing future human needs and ambitions. One of the most ambitious and rigorous of these solutions is P2P Urbanism.
P2P Urbanism is a process of open-source urban intervention carried out cooperatively across a spectrum of people and agencies with vested interest in the evolution of their urban environment, not just architects and city planners. It is primarily based on the application of analogous techniques of file sharing and open-source software with design patterns generated by Christopher Alexander. The idea underpinning P2P being that it is a reflection of the human elements available for input and so, theoretically, will reflect the very needs and ambitions of those engaging with the process. Thus, with greater engagement, across a broad spectrum of human groups and agencies, P2P can potentially address the need for reconnection of the urban environment at a human scale whilst offering progressive alternatives to urban sprawl and monoculture through Alexander’s designs; a potentially true reflection of us in the environment within which we reside. With Bristol’s burgeoning IT-centric industry, the potential a concept like P2P has to illicit a desirable trend of urbanisation, one which fosters a reconnection between people and place, is great.
Jinu Kitchely states, in her 2015 article on Fractals in Architecture, that “architecture as an art form enjoys the privilege of spatiality in addressing human perception and sense.” A complete biophilic environment would be one which fully addresses human perception and sense, “architects who have responded to this instinctive need, by going beyond structural constraints and catered to the emotional needs of the user, have historically achieved much more than the creation of mere shelters.” An obvious source of inspiration for the biophilic environment is nature, with many architects and designers “probing vehemently into the nature of natural forms and organisms to identify and understand the great concepts of the master designer.”
A key concept of the biophilic principle, as applied to architectural design, is the incorporation of nature’s morphology iteratively in the urban re-shaping process. I have previously spoken about how complexity arises from fractal systems, the basic quality of fractal geometry being that it is iteratively-defined – it must be described in terms of steps involving the result of previous steps. Over infinity, fractal generation is recursive and so, in theory is infinitely complex. Benoit Mandelbrot stated in his seminal book ‘The Fractal Geometry of Nature’ that the physical manifestation of this theory, of objects substituting themselves for copies of themselves, can be seen all around us and is the basic process that underpins all living things. Christopher Alexander’s analogue for this is that of a bone’s form which, evenly distributes structural stress across its surface, emerges as a result of a biological program telling cells to add bone mass where stress is likely to be greatest and so is an example of physical and structural feedback shaping the object.
Analysis from Richard Taylor’s research suggests that eye patterns traced from observations of Jackson Pollock’s paintings (left) elicit a significant physiological response in the posterior of the human brain that reduces stress through pattern recognition (right) (source: blogs.uoregon.edu).
Professor of Physics, Psychology and Art at the University of Oregon, Richard Taylor has created an interdisciplinary team that investigates the physiological response of humans when they observe these fractal patterns. Termed fractal expressionism, using work produced by Pollock and Escher, Taylor’s team has found that the format in which people examine these patterns can elicit a positive physiological response, one which reduces stress as the fractal structure of the human visual cortex resonates with the fractal image identified. From the discovery of fire by early humans to the evolution of contemporary artistic concepts, neural and physiological sense and response to natural, iterative patterns of the world around us has been influential in directing the evolution of the human brain and its emotive response system. From this understanding, it seems logical to assume that the structures we build in the environment around us possess the potential to have an impact on this system too.

Connection & disconnection

Now, as this colloquy reaches a coda it feels important to illustrate some examples of successes and failures in respect of that which is written above. The images directly above, taken of the Heygate Estate in London once all residents had been removed from the large estate complex; some forcibly others under enforced willingness – as their lifelong homes were subject to a compulsory re-purchase at 40% of their actual value. The images depict discontent and anger, indeed more damning than the enormous displacement of a strong community under duress, is that the majority of flats and houses built on the land of the Heygate have been sold to overseas investors for a price vastly above what the old flats were purchased for. It is clear that this style of urbanisation is one which fosters a disconnection between people and place.
The iconic Trellick Tower, Westbourne Park, London. Considered an eyesore in its early days and symbol of failure for the utopian architectural ideals of the ‘streets in the sky’ movement of the 60’s. The brutalist structure is now credited as a glowing success of how distinct architectural style can connect a community (source: architectsjournal.co.uk).
Just one and a half miles away from the Heygate is Trellick tower. Ernö Goldfinger’s brutalist 70’s masterpiece, designed as a positive response to the ‘architecture of doom’ employed by the Nazi’s during WWII. The tower employed biophilic facets of utilitarian materials and purpose to create an iconic aesthetic that emphasised robust and reliable living spaces for residents with community as a centrepiece. In the years since its completion, the tower has had a fair share of criticism but has since emerged as an iconic element of the London skyline, an aesthetic centre-point of the city’s urban fabric and one which is now seen as a triumph of biophilic ideals. Much like Corbusier’s Chandigarh and Bofil’s La Murilla Roja, Trellick made the needs of the human scale a priority, with form and function evolving from there. Chandigarh is consistently seen as the standard of how biophilic ideals can be applied to planned cities, Corbusier’s design for the city was based on the human body, and Bofil’s La Murilla, a community housing project in Alicante, looked to connect the residents with the cliffs into which it was built and the sea below, whilst providing a stimulating and iconic aesthetic to foster the sense of a unique community.
Images of La Murilla Roja (top) and The Palace of Assembly, Chandigarh (bottom) (source: Wikipedia).
These iconic buildings and cities contain unique community characteristics, and this is because they incorporate a consideration for just that. As British cities expand to cope with demand and greenfield sites are increasingly developed to provide affordable housing, the concepts discussed above, and examples highlighted throughout, must be considered with a view to sustainable progress. Trellick tower, Chandigarh and the like provide an iconic representation of a time and a place in our relationship with the built and natural environments, they can provide inspiration for what is possible.
Concepts like Salingaros’ P2P urbanism offer an inclusive approach for the future development of cities, currently or due to be, undergoing great change; like Bristol. Ultimately, systematic social vulnerability is a complex convolvulus of interactions on a vast spectrum of scales, addressing it should be a priority and opening the avenues of investigation outlined above is one way to begin.
Sir Denys Lasdun, said of the architect’s job as being “Not to give a client not what he wants but what he never dreamed that he wanted; and when he gets it, he recognises it as something he wanted all the time.” By considering how to connect us with our urban environments more, through the conduit of nature and the biophilic, the author believes that the process of urbanisation can afford us with a sense of place far beyond our dreams and more importantly, one which we should have had all the time. Failing this, follow the advice of the billboard below and enjoy the gifts of nature before they are consumed by the belligerent grey beast of indifferent urbanisation.
