beyond zero carbon housing - mario cucinella
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

ventilation provides an increased
comfort level for building
occupants and during night it cools
the thermal mass in order to
prevent over-heating of the
structure.
The design of all transparent surfaces
was based on daylighting simulations
to study the dimension and position
of:

1)windows
2)transparent panels
3)skylights
in order to reach a balance between
daylighting, shading effects in
summer, solar gains in winter.
