Building concept and some technical aspects and questions

The concept for the units for the office and lecturing spaces is based on the idea of creating a unity between the structure of the building (three sides sand-bag-walls) and the more open front and the roofing structure. In this way, the trusses that support the actual roof (corrugated iron sheeting) rest on the walls and the cantilevered part is additionally supported by a gum-pole structure. Thus we can generate cross-ventilation within the units by having windows at the lower side and ventilation windows at the higher end of each unit, permitting the hot air to escape at the top, the trusses with a hight of min. 35-40 cm carry the ceiling (insulated and panelled) on the inside of the spaces and above, the roof battens rest on the upper part of the trusses to carry the corrugated. This enables the sun to heat the metal roof that propels the air and pulls it under the roof and above the ceiling with a natural cooling effect.

The realisation as mentioned above wants to be very simple but effective to passive heating and cooling for winter and summer. The cantilever of the roof needs to be set to enable this according to the inclination of the sun in summer (87°) and winter (42°).

open questions at this point:

can the eco-beam trusses be used to achieve this cantilever?

how far can you go without additional support (we are envisaging 1,50 - 1,80 m) on the lower side and mabe up to 3,5 m on the higher side to generate the ever pleasant shade on the court yard side of the buildings.

The other aspect to investigate is the aspect of availability of materials:

sand we know that we can find;
foundations, with rocks (bricks?) and cement, we can create a good base;
the floor needs to protect from humidity so what ever we use as finish, a damp course will be necessary;
gum-poles will be necessary to a big extent to support the roofing;
material for the front like shutter board (will try DOKA again);
sheeting material, could be metal, but alternatives are welcome;
windows, sliding doors and glasing as well as ventilation slits will have to be bought;

looking forward in having a little discussion on this soon!!

    No problem with using the Vinn Ecobeam for the roof to achieve the Cantilever - We can use structural beams (Slightly thicker wood and aluzinc lattice)The gum pole will provide more than enough support.
    How about Sandbag foundations and floor bases?

    good point, will have to look at that in detail, is there anything on the foundations in your presentation?? and floor, well a cement surface with a waxed coating in various colours, or cow-dung, the original authentic technique, lets talk!!
