Sustainability










Curatorial Idea:

Each pavilion concentrates on one topic of green building. The topic is content but also architectural programme.

The topics to be addressed are :

- geothermical energy

- solar energy

- drainage and xxx of water

- air xxx

- building envelopes

- life cycle of materials






Sustainability measures





1. Minimising heat-loss through the building skin by:
Using compact building form

2. Minimising heat-loss through the building skin by:
high levels of thermal insulation

3. Minimising heat-loss trough ventilation by:
tighly sealing the building

4. Minimising heat-loss trough ventilation by:
extracting heat energy from exhaust air

5. Minimising heat-loss trough ventilation by:
pre-heating supply air in the Winter
through the geothermal heat exchange system

6. Optimising thermal protection in the Summer by:
pre-cooling fresh air in subterranean air passages
of geothermal heat exchanger

7. Optimising thermal protection in the Summer by:
exterior solar protection in the tripied- glazed windows

8. Optimising thermal protection in the Summer by:
efficient interior mounted shading of the glaze roof

9. Optimising thermal protection in the Summer by:
cooling at night with fresh air to exploit the thermal
mass of the building´s primary structure

10. Maximising the passive use of solar Energy with:
flexible solar protection for the offices which allows
low winter sun into the rooms

11. Maximising the passive use of solar Energy with:
active use of solar energy with thermal solar collection/
photovoltaic collectors

12. Tempering the building climate, using the atrium:
in offices facing onto the atrium:
natural air ventialtion by opening the windows
as well as exhaust air through `overflow` elements
into the atrium by natural convection

13. Tempering the building climate, using the atrium:
in offices located on the exterior facade:
exhaust air through òverflow`elements into the atrium
by natural convection

14. Optimisation of the use of daylight through:
a relatively narrow building with (11.8m)

15. Optimisation of the use of daylight through:
an optimised proportion of window glazing: ca. 35%
of exterior and ca. 60 % of the interior facades

16. Optimisation of the use of daylight through:
the use of surfaces to direct and reflect daylight

17. Further ecological measures:
district heating from landfill methane

18. Further ecological measures:
use of recycled material and ecological, biodegradabie
and reusable building materials

19. Further ecological measures:
planted roofs
