CBES Platform Grant - The Unintended Consequences of Decarbonising the Built Environment

Gaining a deeper understanding of the physical performance of built environment choices and their implications for energy use, health, conservation, productivity and climate change.

7 July 2017

The Complex Built Environment Systems group (CBES) is a dynamic team of academics working together to gain a deeper understanding of the physical performance of built environment choices and their implications for energy use, health, conservation, productivity and climate change.  CBES is primarily interested in developing solutions to the practical problems of designing, constructing, and managing appropriate environments within and around buildings.  

In 2006, CBES was awarded a prestigious five-year platform grant from EPSRC in recognition of its "world-leading" research into the complex built environment.

This platform grant was renewed for another five years in 2011 in order to allow CBES to focus on the unintended consequences of de-carbonising the built environment.

The grant was renewed for another five years for a second time in 2017, with CBES now focusing on transforming the scientific understanding of the systemic nature of a sustainable built environment.

Recent examples of engagement in 2016 include:

We are currently involved in a series of on-going projects which involves over 50 successful collaborations with other research teams / institutions. In April we were visited by a large team from Tsinghua University for a 2-day workshop regarding the new EPSRC funded ‘TOP’ (‘The ‘Total Performance’ of Low Carbon Buildings in China and the UK) project. We have undertaken the initial round of interviews with stakeholders for the system dynamics work and also arranged for access to suitable buildings for the monitoring work which has now begun. The HEW report has been published.  This involved very significant engagement with approximately 50 stakeholders and hence this work is a major knowledge exchange success for CBES. A large stakeholder workshop was held at the end of June We launched the new UCL IEDE Master’s Degree in ‘Health, Wellbeing and Sustainable Buildings’ at VISION - a event aimed at architects, specifiers and their clients. Members of CBES contributed to the Committee on Climate Change UK Climate Change Risk Assessment 2017 Evidence Report, providing vital evidence to assist with government policy on climate change adaptation and mitigation for the built environment The UK Centre for Moisture in Buildings (UKCMB) held its launch conference at UCL The aim of the UKCMB is the development of a moisture-safe built environment in the UK. The centre is the brain child of CBES member Neil May. The UKCMB team has been awarded Innovate UK funding for a 2 year KTP project co-funded by the Property Care Association (PCA). The EPSRC funded ‘MERLIN 2 ‘project (led by Peter Raynham) to undertake work to reduce the energy consumed by road lighting, whilst maintaining the visual benefits, continues. This project is aimed at understanding the needs of pedestrians at night Flood House, launched in April, was a collaborative project between UCL IEDE CBES Staff and  The Bartlett School of Architecture This mobile prototype structure travelled along Thames Estuary for four weeks as part of the Radical Essex project We now have a series of ‘so-what?’ reports published on the ARCC network where we disseminate CBES research in an easily to read format for a wider audience. CBES continues to contribute to the Scientific Board of ‘Healthy Polis’ – the International Consortium for Urban Environmental Health & Sustainability.
