Meet the team

Tim Lunel
Project Manager for Cosy Homes Oxfordshire
Tim is an experienced project manager. He was Chief Executive of The National Energy Foundation 2005-2012, and is Chair of the Microgeneration Certification Scheme – so he was been working in the home energy sphere for much of his career, during which time the technologies to improve the fabric of buildings and low carbon technologies have improved significantly, and the UK has made progress in decarbonising the grid.
Tim is Treasurer of Hook Norton Community Land Trust and has led the project to get planning permission for 12 new-build PassivHaus homes. He is Company Secretary of Hook Norton Low Carbon Limited – a low carbon community group which was awarded the status of Energy Neutral Village in 2014 in the ACE Awards (Academy of Champions for Energy), one of Europe’s most high-profile events that recognises achievements in renewable and sustainable community energy.

Russell Smith
Founder of RetrofitWorks and Parity Projects, and Cosy Homes Oxfordshire project partner
Russell is a chartered civil engineer with years of experience of retrofit, and is the founder of both Parity Projects (leading exponents of retrofit expertise for larger scale approaches) and RetrofitWorks.
He has run a number of large scale retrofit programmes – most recently the £4.5m Warmer Homes programme on behalf of the Mayor of London, and is involved in a 250 heat pump roll-out for OVO energy. As MD of Parity Projects he has worked with the Greater Manchester Combined Authority to build a model of their 1.5m homes, and a national retrofit model to support plans for a National Retrofit Programme for the Construction Leadership Council.
Widely recognised as an industry expert, Russell is a regular speaker at conferences and contributor for industry publications. Take a look at the RetrofitWorks LinkedIn posts for links to his latest interviews, articles and podcasts.
