[week 14] alternatives and conclusions

Every system design has some alternatives that I will show below. There can be made conclusions about the system, pavilion design and Cradle to Cradle.

system design 1: technical

alternatives

1 The roof cladding can be coated steel, aluminium, copper, zinc, or bitumen.

2 Insulation can be EPS, glass wool, or stone wool.

3 substructure can be steel or aluminium

4 structure can be steel or aluminium

5 interior cladding can be stone wool, perforated steel, bio-rock or gypsum board

choice

1 aluminium for its resistance to release toxic metals in the rain water.

2 glass wool for its low mass and environmental aspects

3 steel for its lower costs and environmental aspects

4 steel for its lower costs and environmental aspects

5 gypsum board for its costs

further research

The following topics can still be further elaborated:

• coatings that do not pollute underlying metals
  

  system design 2: steel-wood
  

alternatives

1 The roof cladding can be wood tiles, coated steel, aluminium, copper, zinc, or bitumen.

2 Insulation can be flax wool, sheep wool, cork, EPS, glass wool, or stone wool (cellulose contains borax).

3 substructure can be fibre board, steel or aluminium

4 structure can be steel or aluminium

5 interior cladding can be wood, stone wool, perforated steel, bio-rock or gypsum board

choice

1 wood tiles for its low environmental aspects

2 flax wool for its low costs and environmental aspects

3 fibre board for its low costs and environmental aspects

4 steel

5 gypsum board for its costs

further research

The following topics can still be further elaborated:

• connection of wood shingles without steel nails
  

• • system design 3: straw board – glue
    

alternatives

1 The roof cladding can be wood tiles.

2 Insulation can be flax wool, sheep wool, cork, straw, or bio-EPS.

3 webs can be straw board or wood

4 flanges can be straw board or wood

5 interior cladding can be wood or gypsum board

choice

1 Wood tiles for its low environmental aspects.

2 Straw for its local availability and applying the heat resistance.

3 Straw board for the thickness and absence of glues.

4 Straw board for integration of functions and better flow of insulation.

5 Wood for its good environmental aspects.

further research

The following topics can still be further elaborated:

• market and feasibility investigation
  
• FJI joists with natural glues
  
• FJI joists with cold wood connections
  
• moisture and long term effects
  

  system design 4: wood joints
  

alternatives

1 The roof cladding can be wood tiles or EPDM

2 Insulation can be flax wool, sheep wool, cork, or bio-EPS.

3 structure can be wood

choice

1 EPDM for its low environmental aspects

2 flax wool for its low costs and environmental aspects

3 wood

further research

The following topics can still be further elaborated:

• wood squire splice joints system design
  

  system design 5: solid wood
  

alternatives

1 The roof cladding can be wood tiles or EPDM

2 Insulation can be flax wool, sheep wool, cork, or bio-EPS.

3 structure can be wood

choice

1 EPDM membrane for its low environmental aspects

2 flax wool for its low costs and environmental aspects

3 wood

further research

The following topics can still be further elaborated:

• overlapping short solid wood parts for Q-concept floors
  

pavilion design

The system design 4 with only wood and other natural materials does fit the criteria very well. Making the wood joints in an industrial way is also innovative.

further research

The following topics can still be further elaborated:

• climate, water distribution and building services
  
• finishing's with waste material
  
• construction of the attached glass house
  

  Cradle to Cradle materializing
  

  why
  

Savings during the exploitation of a building can be easily defended during the design phase. More difficult are savings at the end of the life span because of higher component or scrap value. But with rising prices of raw materials and awareness of the environment some attention for the Cradle to Cradle ideas worth it. Improvement of human health conditions is of importance for the user of the building. With only a small decrease of absenteeism is a large cost saving possible.

evaluation

Using materials like before the first industrial revolution will mean a more effective use of the materials. This is not always possible today. And today's designs require forms that cannot be made from only natural materials. The only way out to materialize this design is to use technical materials like recyclable watertight foil.

Does this mean that this experiment has failed because 100% Cradle to Cradle is not achieved? In my opinion not because it shows that innovation can reach the destination at the end. This may be done in little steps but is must happen if we want to give our children the same opportunities that we have.

SWOT

strengths

• willingness of parties
  
• better performance than practice as usual
  

weaknesses

• not objective without quantitative comparison
  
• commercial background of certification
  

opportunities

• future benefit
  
• simplification of details with less cost
  

threats

• building regulations
  
• extra costs
