Material Information for Architects
- 1. VRA Toronto 2009 Material Information for Architects Donna Kacmar University of Houston [email_address]
- 3. process innovation + product innovation
- 6. http://www.materia.nl/ + www.transstudio.com/ www. greenbuildingpages .com/press/Benchmarking/GBP2007CreditUpdate. htm www. healthybuilding .net/news/061109pharos.html www. healthybuilding .net/news/060629labelgame.html www. pharosproject .net/ www. localgreenmaterials .org www.core77.com www.idsa.org www.matweb.com www.ides.com www.materialconnexion.com
- 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

Instn Civil Engrs: Energy , 161 (2): 87-98 http://www.atypon-link.com/TELF/doi/abs/10.1680/ener.2008.161.2.87 https://wiki.bath.ac.uk/display/ICE/Home+Page
- 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+
- 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
- 38. history of material from discovery to now
- 39. precedents in use in buildings or products
- 40. life expectancy (durability) in years
- 41. cost per sq. ft. of specified thickness for material cost only for material + labor? for place it will be installed
- 42. standard sizes maximum sizes
