A one day symposium on zero/low carbon sustainable homes took place at The University of Nottingham on the 24th October, 2012. The event offered professionals within the construction industry a unique opportunity to gain added and significant insight into the innovations, policies and legislation which are driving the construction of zero/low carbon energy efficient homes both here in the UK and elsewhere in Europe. It explored solutions to sustainability issues “beyond” the zero carbon agenda. BZCH followed on from the successful ‘Towards Zero Carbon Housing’ symposium the University hosted in 2007. This event is part of the Europe Wide Ten Act10n project which is supported by the European Commission Intelligent Energy Europe.
