This document provides information for architects on selecting materials for buildings, including intrinsic and extrinsic material properties to consider, methods for evaluating a material's composition, manufacturing process, environmental impacts, and precedents of use. It outlines metrics like embodied energy and water, density, strength, durability, and cost, and lists resources for researching materials. The document proposes a collaborative online materials database hosted with schools to share intrinsic property data and a school-specific database with extrinsic properties, physical samples, and research.

7. material explorations

12. material research

13. how do we select materials for a building?

14. how do we select materials for a building? visual characteristics + cost

15. INTRINSIC PROPERTIES (remain constant ) properties that are inherent to the material and can be measured mechanical + electrical + physical + chemical + thermal properties: strength toughness conductivity density reactivity EXTRINSIC PROPERTIES ( vary depending on project, location) properties that are dependant on context (time and place) of processing and application optical properties acoustical cost (initial cost + life cycle cost) durability cultural value

16. composition of material the chemical and mineral content from the chart

18. VOC volatile organic compounds as a percentage or parts per million (ppm) from the Material Safety Data Sheet or call manufacturer or product representative

19. origin of raw materials where (in the world) are the raw ingredients mined or removed from the earth? locate on a map. how far away is that from the building site? you will need a specific material or product to trace its exact path

20. manufacturing process how the raw material gets made into a finished product how much energy is used? how much water is used? does the process pollute air or water? does it harm the employees working at the manufacturing facility?

21. energy used in manufacturing cradle to gate expressed as MJ per kg or BTU per ton convert to BTU per sq. ft. of specified thickness for cladding materials

22. Titanium 430 MJ/kg Polycarbonate 86 MJ/kg Float glass 15.9 MJ/kg Cypress 2 MJ/kg

24. energy used in transportation gate to site = transportation method x transportation distance RAIL: 344 BTU per ton-mile BOAT: 417 BTU per ton-mile TRUCK: 4,300 BTU per ton-mile PLANE: 31,600 BTU per ton-mile (2003 energy intensities )

25. embodied energy = cradle to gate + gate to site

26. embodied water amount of water required in manufacturing process (including extraction of raw materials) L per kg convert to gallons per sq. ft. of specified thickness

27. weight pounds per cubic foot pounds per sq. ft. of specified thickness

28. density weight per unit of volume pounds per cubic foot

29. R value insulation property of a material (the higher the number the greater the insulative qualities) U value: how well a material conducts heat

30. compressive strength ability of material to resist loads/force pounds per square inch (psi) metals are more elastic under loading ceramics fail suddenly and unpredictably

31. tensile strength nominal stress at which the material, loaded in tension, separates pounds per square inch (psi)

32. sound transmission rating how well a partition attenuates airborne sound the decibel sound reduction the partition offers (dB) STC rating

33. UL Flame Spread rating relative rate at which a flame will be spread in a material Class A: 0- 25 Class B: 26-75 Class C: 76-200 Class D: 201+

34. recycled content %

35. ability to be recycled readily possible not possible or can material be reclaimed?

36. electrical/magnetic conductivity: ability to conduct electrical current resistivity: ability to resist electrical current magnetic properties

37. coolness/warmth thermal diffusivity: ability of a material to transfer heat in a nonsteady state condition square metres per second thermal conductivity: ability of a material to transfer heat in a steady state condition
