Graduating with an MA in Creative Writing in 2021, David Shiers was formerly Reader in Sustainable Property and is now an Affiliate of the School of the Built Environment at Oxford Brookes University. He was co-author (with BRE) of the Green Guide to Specification - an environmental profiling system for construction materials and part of the BREEAM and the Code for Sustainable Homes programmes; helping designers and specifiers to reduce the environmental impacts of their buildings. Globally, there are more than 558,200 BREEAM certified developments and almost 2,260,300 buildings registered for assessment. Green Guide has been the recommended materials specification standard for the UK Government, many Local Authorities and private sector organisations such as the Westfield retail group and was used in the building of the London 2012 Olympics. David was a judge on the Construction News panel for the national UK Building Quality Awards between 2010-2013. His research paper, Socially Responsible Property Investment (SRPI), written with Miles Keeping, Dan Rapson and Claire Roberts, was cited as a key text in United Nations Environment Programme (UNEP) Finance Initiative report Building Responsible Property Portfolios.
