Idea one of 12 in with a chance to win £50 000
An idea to retrofit existing buildings in African cities with 3D printed porous insulation panels to improve liveability and reduce energy consumption for cooling and ventilation has been named African winner of the Cities for our Future competition run by RICS (the Royal Institution of Chartered Surveyors). It now goes on the global shortlist of 12 ideas with the overall global winner to be announced in November 2018.
With peak shade temperatures of over 40 degrees becoming more common in African cities, the need to artificially cool and ventilate buildings is consuming more energy and increasing stress on already-stretched infrastructures of energy generation and distribution.
The scheme, proposed by Heat Island Limited, a multidisciplinary design team from the UK, is a flexible retrofitting process in which the passive thermal regulation and overall resilience of existing buildings can be improved, while leaving existing homes and communities in place. A flexible and inhabitable ‘wrapper’ around the existing facade passively cools the structure using radiant cooling of the existing concrete frame during the night, and evaporative cooling of the interior during the day.
The system, named Evaporos, uses moveable 3D printed porous ceramic panels to enable the facade-wrapper to ‘close down’ during the heat of the day, and to open up fully at night. This diurnal cycle increases thermal comfort while reducing energy consumption and removing the need for mechanical cooling and ventilation.
The eight-man team, which came up with the idea, is one of 12 entrants on the final shortlist, which has been narrowed down from more than 1 200 entries. Heat Limited is now in with a chance of winning the competition’s £50 000 prize.
RICS is running the competition to encourage young people around the world to think about the challenges facing the world’s cities and to draw upon their imagination and innovative ideas to create real, practical solutions that global cities can implement.
Joseph Augustin, one of the team leads said: “As peak temperatures across Africa and the world continue to rise, there is a major need for cooling solutions which avoid creating additional energy load. Evaporos is a response to the specific problem of already-existing buildings, as well as an opportunity to enhance public space and social infrastructures in arid megacities. As a young multidisciplinary design team, we’re delighted to have the opportunity to work with a mentor to develop and further explore the potential of our idea.”
With three million people moving to cities every week, the rapid expansion of urban areas the world over is putting ever more strain on infrastructure and services. Many city dwellers live in slums or poor quality housing or have to contend with poor air quality and inadequate transport links.
The next step in the Cities for our Future competition run by RICS, in partnership with the United Kingdom National Commission for UNESCO and the Association of Commonwealth Universities, will see each of the 12 finalists given a RICS mentor to help them develop the idea in advance of the final judging in November.
The overall winner will be announced at a ceremony in November.
Joshua Askew of JLL, Head Judge of the regional judging panel for Africa said: “We were impressed by the quality and quantity of entries for Africa. Our continent has a rapidly growing urban population and is particularly vulnerable to the impacts of climate change. This idea stood out because of the simplicity of the solution it provides to the problem of cooling buildings without using more energy. We wish Heat Limited and all the finalists good luck and hope that we will get the opportunity to pilot their ideas in African cities.”

About Cities for our Future
Cities for our Future is a competition run by RICS, in partnership with the UK National Commission for UNESCO and the Association of Commonwealth Universities, in which young people around the world have been invited to offer inventive, but practical solutions to the most pressing challenges facing the world’s rapidly expanding cities.
Entrants were asked to submit ideas on three overarching issues facing cities around the world – urbanisation, climate change and resource scarcity.
The competition launched on Wednesday 17th January 2018 with a closing date for entries of 31 May 2018. The entrants were judged at a regional level by leading experts in surveying, engineering, city infrastructure and related fields. Judges included professionals from global property firms such as JLL and Cushman & Wakefield, academics from NYU and Massey University and government bodies including the government of Qatar and the Singapore Centre for Liveable cities.
Now in its first year, the competition received over 1 200 entries which have been narrowed down to a final 12. The shortlisted entries address problems in cities the world over, including Beijing, Amman, Caracas, Glasgow and Delhi. The overall winner will be announced in November 2018 and will receive a prize of £50 000.
