Beyond Zero Carbon Housing - Alan Shingler


Published on

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.

  17. 17. Solar gain and shading• At Level 6 there is a mandatory heat lossparameter• As a result the ratio of glazing to wall in theLighthouse is 18% as opposed to 25-30% intraditional houses.• This drove our decision to locate the livingspace on to the first floor enabling us tomaximise daylight and volume, with a top-litdouble height living space.
  18. 18. Selective thermal massPhase changing material in the ceilingsabsorbs the room heat by changing from solidto liquid within microscopic capsulesembedded in the board. This process isreversed when the room is cooled with thenight air, working with the passive system ofthe wind catcher.

  21. 21. The energy cost of running the Kingspan BREhouse would be about £31 per year for thewood pellets, assuming wood pellets cost 1.8p/ kWh. The electricity is free, from the sun! Ahouse of the same size and shape but built to2006 Building Regulations standards wouldcost about £500 a year in energy bills.
