Lecture B
Environmental and Natural
Building Materials
Why do we use natural materials?
• Low energy content
Energy content of some materials
Aluminum 70,000 kW.hr / ton
Plastic 25,000 Steel 15,000 Cement 2,000 Clay brick (burned) 500-2000
Cement brick 700-2200 Stone (cut) 150 Stone (rough) 100 Mud brick 30 Wood 30-100
Why do we use natural materials?continued
• safe and hygienic:– Asbestos corregateg sheets vs. wood shingls or
fiber glass
• Renewable or practically non depletable– Wood , steel and Plastic
• Recyclable or Nature Absorbable– Mud brick, wood roofs, vs cement bricks and concrete roofs.

Why do we use natural materials? (continued)
• Durable and efficient: – marble and Granite vs ceramic or mosaic tiles
• Sensual comfort: – Warmth (air content and thermal capacity)
• Emotional comfort:– a link with nature, past memories…
• Aeasthetic values :– Diversity, rhythm, .. – Sustainable value, not not lost as fast as fashion
materials.• does not threat ecosystem nor threatened
species
How deep is it natural?
• Massive wood Furniture• Veneered, laminated (plywood),
composed (Counter)• Painted wood• steel or plastic furniture• Textiles
– Cotton, wool, silk vs. Nylon and senthetic

Ethics of Nature and natural Materials
• How many creatures did you kill to get this material?
• Is it accepted to kill an Animal?– Yes, for food! and get any by-products.– No, for fun! Better Shoot with a camera– Yes, if Nature will not suffer because of
killing the Animal– No, if biodeversity is threatened, or any
negative Environmental Impact is expected.– No if the role of the Animal in the
ecosystem is much larger than the benefit of the material
Ethics of Nature and natural Materialscontiued
• It is fine to use caw leather, but not mink or fox fur
• It is fine to use sea shells (specially thrown at the shore) as inlayes in decoration, but not ethical to use Ivory
Assignments:
• design a report cover from Natural Materials:– Wood, leather, rough Natural textiles, papyrus, bound
sticks …..The Cover should express the respect of nature both in Material and design
• write a brief essay about the value and benefit of natural materials in Architecture.support your essay with illustrated examples
