beyond zero carbon housing - alan shingler
DESCRIPTION
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.TRANSCRIPT

Positive aspects : Contemporary look, open plan ground
floor, good daylight provision, high ceilings, uniqueness of
lantern.
Negative aspects: lack of storage space, entrance sequence,
heating provision and controls, use of MVHR system
The Code for Sustainable Homes How it worksThe Code for Sustainable Homes
Its ambition is clear; guiding the design and
construction of sustainable homes to set
world class standards that reduce the impact
our homes have on the UK’s carbon

• At Level 6 there is a mandatory heat loss
parameter
• As a result the ratio of glazing to wall in the
Lighthouse is 18% as opposed to 25-30% in
traditional houses.traditional houses.
• This drove our decision to locate the living
space on to the first floor enabling us to
maximise daylight and volume, with a top-lit
double height living space.
Selective thermal mass
Phase changing material in the ceilings
absorbs the room heat by changing from solid
to liquid within microscopic capsules
embedded in the board. This process is
reversed when the room is cooled with the
night air, working with the passive system of
the wind catcher.
BRE Innovation Park 2007
Innovation – Raising the profile of Sustainable Design
The energy cost of running the Kingspan BRE
house would be about £31 per year for the house would be about £31 per year for the
wood pellets, assuming wood pellets cost 1.8
p/ kWh. The electricity is free, from the sun! A
house of the same size and shape but built to
2006 Building Regulations standards would
cost about £500 a year in energy bills.
