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.

  3. 3. creative empathy creativity and social rensponsibility in architecture
  4. 4. responsibility
  5. 5. From 2006 onwards MCAbuildings and officeactivity have saved about8225 ton CO2-eqThis data is referred only to the actual constructed buildings analyzed in this survey
  6. 6. …but architecture goesbeyond the technicalperformance ofbuildings
  7. 7. Each building has the potential to redesign, notonly the internal spaces, but also the surroundingnatural, cultural and socio-economic systems.Building can recreate the intimate relationship (the“creative empathy”) linking places, theirinhabitants and the right use of technologies, thusenabling the achievement of enriching and enablingenvironments for life and work.
  8. 8. creative empathy the distinctive featuresLow tech / high performance buildings empathy with the environment Beauty and vernacular innovation empathy with culture and historyBuildings as catalysts for social change empathy with society

  14. 14. beauty and vernacular innovation Green School for Gaza 0 CO2, -60% water demand, 0 oil
  15. 15. 19 classrooms 1330 pupils
  16. 16. innovative vernacular architecture ancient techniques + new technologies One of the traditional houses in Palestine was made fromstone or excavated in rock, but the majority of them were of sun-dried brick covered with tree branches.
  17. 17. excavations for foundations, pillarswater tanks and heat storages the school structure
  18. 18. Overhanging roof: steel beams on earth bricks wallVaulted slabs:compressed earth block floormade of jack arches Concrete slab as foundation Pillars: concrete-earth blocks precasted on site
  19. 19. comfort comes from the design
  20. 20. ventilated roof daylight natural ventilation mashrabiya inner thermal garden massshading panels
  21. 21. …and the use of simple techniques
  22. 22. winter 272 sqm of photovoltaic cells 6 rainwater columns100 sqm of thermalsolar panels 2 water treatment lands air pipes located beneath the slab
  23. 23. summer potted trees to shade the roof20 solar chimneysto improve airextraction overhanging roof thermal mass geothermal ventilation
  24. 24. thermal comfort - 4°C Outside T. 34° C Inside T. 30° C 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.
  25. 25. 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.
