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.

3. creative empathy
creativity and social
rensponsibility in architecture

4. responsibility

8. From 2006 onwards MCA
buildings and office
activity have saved about
8225 ton CO2-eq
This data is referred only to the actual constructed buildings analyzed in this survey

9. …but architecture goes
beyond the technical
performance of
buildings

10. Each building has the potential to redesign, not
only the internal spaces, but also the surrounding
natural, cultural and socio-economic systems.
Building can recreate the intimate relationship (the
“creative empathy”) linking places, their
inhabitants and the right use of technologies, thus
enabling the achievement of enriching and enabling
environments for life and work.

11. creative empathy
the distinctive features
Low tech / high performance buildings
empathy with the environment
Beauty and vernacular innovation
empathy with culture and history
Buildings as catalysts for social change
empathy with society

12. Low tech / high performance buildings

Green School for Gaza
0 CO2, -60% water demand, 0 oil

25. 19 classrooms 1330 pupils

26. innovative vernacular architecture
ancient techniques + new technologies
One of the traditional houses in Palestine was made from
stone or excavated in rock, but the majority of them were of
sun-dried brick covered with tree branches.

In summer the project enables to
reduce the operative temperature
up to 4 degrees for the ground
floor classrooms each one
occupied by 35 children.
During the day the natural
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.

35. visual comfort
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.

36. a better learning space
