Open-City’s Green Sky Thinking Week was launched this morning (23 April) with a debate asking ‘How does London get to number 5?’
Hosted by Greater London Authority at City Hall's London Living Room the launch received a full house of 120 people, including key supporters, partners and guests from across the sectors of property development, planning, real estate, housing, architecture, engineering, innovation design and sustainability.
With an introduction by Mark Jenkinson, City Director London, Siemens,
the debate panel included:
The topic of the debate referred to the Siemens Green City Index from 2009, which assessed 120 cities worldwide to determine their sustainability credentials. London, although better than the average level, was ranked 11th in Europe, coming 10th in the buildings category, and 15th in governance.
Mark Jenkinson, Siemens’ City Director for London introduced the debate explaining the methodology behind the index, which was split into 8 categories, of which 4 he focused on in his presentation: energy, CO2, buildings, and environmental governance. His presentation here was apt, as he cited one of the main aims behind the index was to highlight best practice and enable debates such as this morning’s and indeed the Green Sky Thinking week programme in general. Furthermore, one of the key findings after looking at 120 cities was that encouraging community participation has been one of the key successes. Have your say on the index in our 3 minute poll.
The question of engagement continued to be at the heart of the discussion – unless people can see change and want change, they won’t buy into it, and crucially, won’t vote for it. This is critical in London’s case, as Matthew Pencharz, GLA’s Senior Advisor Environment & Energy was keen to emphasise. With 3 levels of government and 33 boroughs working below the Greater London Authority – itself a very new institution – London is a unique case politically, as each borough is naturally very protective of their own competency. However he was confident that despite this, more and more boroughs are forming partnerships across London, with the mayor’s support.
From this perspective, Niall Bolger, Chief Executive of LB Sutton, confirmed that there is a strong appetite locally to make changes, with many different initiatives and organizations bringing people together. He advocated keeping decision making as close as possible to residents that the borough serves, and most importantly making sure that the technical aspects of sustainable development are accessible to all.
With the discussion heavily focused on governance, the question turned to Isabel McAllister, Sustainability Director at Mace to answer for the commercial sector. Of course, she said, businesses do not run on 4-year cycles, so have much more power to drive performance. She celebrated the fact that London is extremely well positioned, and encouraged the audience to celebrate success rather than always looking at restraints. She described the huge movement in the business world towards green innovation, with commercial success as a result.
However as much as new sustainable initiatives and technology have been successful, London is by no means a new city, with centuries of infrastructure to build around and on top of. Therefore the question of refurbishment came up in relation to commercial clients: will it be widely adopted as a mode of economic driver or will they always prefer the knock-down-and-start-again approach? Nick Hillard, Sustainability Manager at BNP Paribas Real Estate, urged that refurbishment needs to be made as sexy as new build, in order that we see a resurgence. Although as Richard Shennan pointed out, it is impossible to certify the performance of an existing structure, so from a client-facing point of view, it is always going to be easier to start afresh.
So what happens in reality? Paul Ruyssevelt, Professor of Energy and Building Performance at UCL, was asked about the barriers to accumulation of good data on performance, in order to use feedback for continuous improvement. Clearly, he said, there is a big performance gap between our expectations and the measurements in reality. There is a definite lack of incentive for businesses to gather this data, not least because there is no obvious method of funding for feedback, and no regulations for operational performance.
Questions from the floor showed the audience’s engagement with the topic, but for some, a need for less discussion and more action. Dan Epstein, Director of Sustainability at Useful Simple Trust complained of the debate not being urgent enough, saying that ‘we are so far away from a really sustainable city’. Others were less pessimistic – Paul Lincoln of Landscape Institute questioned why green infrastructure was not part of the Siemens Index, as a reminder of London’s strength 'being the greenest city in the world' in comparison to other cities. Isabel McAllister agreed with Lincoln's statement that Green Infrastructure should have been considered in the Index but it was Nick Hillard who brought the discussion full circle to Matthew's original point that unless people understand the language used, behaviours will not change, and noted Green Infrastructure as a term needs to be rethought.
The debate was closed by Kelly Grainger of Interface, with the statement that when it comes to sustainability, individuals do not and cannot win the race alone. It is collaborative teams and integrated design solutions that will move London up the index. As a lasting piece and considering the debate topic, he asked why we aren’t setting goals higher than merely reaching number 5, but emphasized we can only get this far or further collectively. Green Sky Thinking Week will show the way!
