Слайд 2

Описание слайда:

Outline Overview of green buildings Principles of green building materials Examples: roofing and floor coverings Conclusion

Слайд 3

Описание слайда:

Green Buildings Holistic approach Sources and impacts of materials Mechanical system efficiency Site / building relationship Innovation

Слайд 4

Описание слайда:

Principles of Green Building Save energy Recycle buildings Create community Reduce material use Protect and enhance the site Select low-impact materials

Слайд 5

Описание слайда:

Building Materials Materials form a large part of the overall environmental burden of buildings Raw material extraction Waste and pollution associated with manufacturing Material installation Public health risks Disposal

Слайд 6

Описание слайда:

Material Life Cycle Assessment Resource extraction Manufacturing and transportation Installation Operation and maintenance Salvage, recycling and disposal

Слайд 7

Описание слайда:

Principles of Green Materials Choose products: made from environmentally attractive materials that are green because of what isn’t there that reduce environmental impacts during construction, renovation or demolition that reduce environmental impacts of building operation that contribute to a safe, healthy indoor environment

Слайд 8

Описание слайда:

Products made from environmentally attractive materials Use: salvaged products products with post-consumer/industrial recycled content certified wood products rapidly renewable products products made from agricultural waste material

Слайд 9

Описание слайда:

Products that are green because of what isn’t there Use: products that reduce material use alternatives to ozone-depleting substances, PVC and polycarbonate alternatives to conventional preservative-treated wood alternatives to other components considered hazardous

Слайд 10

Описание слайда:

Products that reduce environmental impacts associated with construction Use: products that reduce the impacts of new construction products that reduce the impacts of renovation products that reduce the impact of demolition

Слайд 11

Описание слайда:

Products that reduce environmental impacts of building operation Use: building components that reduce heating and cooling loads energy & water conserving components renewable energy and fuel cell equipment products that prevent pollution or reduce waste

Слайд 12

Описание слайда:

Products that contribute to a safe, healthy indoor environment Use: products that don’t release significant pollutants into the building products that block the introduction, development or spread of indoor contaminants products that remove indoor pollutants products that warn occupants of health hazards in the building

Focus Building Materials Roofing Asphalt / fiberglass composition Aluminum / steel Metal Floor Coverings Wood Natural linoleum Carpeting / carpet pads

Слайд 14

Описание слайда:

Principles Discussed Durability Recycled-content

Слайд 15

Описание слайда:

Roofing Criteria Durability 25-year minimum warranty Color Use light colored roofs Increases durability Decreases reliance upon mechanical cooling

Слайд 16

Описание слайда:

Roofing: Options for Shingles Asphalt / Fiberglass Composition Very durable 40-year warranty Some recycled content

Слайд 17

Описание слайда:

Roofing: Options for Shingles Metal Durable 100% recycled content Recyclable High embodied energy costs

Слайд 18

Описание слайда:

Comparison of Materials

Слайд 19

Описание слайда:

Floor Coverings Criteria Durability Resource efficiency Indoor air quality Offgassing concerns

Слайд 20

Описание слайда:

Floor Coverings Wood Reclaimed wood flooring Sustainably harvested wood flooring Bamboo flooring Natural Linoleum Durable Abrasion resistant

Слайд 21

Описание слайда:

Floor Coverings Carpeting Must be replaced frequently Large contributor to landfill waste Traps dust, mold, bacteria Carpet pads Durable with recycled content Use of recycled materials Offgassing concerns

Слайд 22

Описание слайда:

Floor Coverings Options Recycled-content carpeting Carpet tiles Carpet leasing Rapidly renewable fibers Use mats or small carpets

Слайд 23

Описание слайда:

Comparison of Materials

Слайд 24

Описание слайда:

General Recommendations Specify at least four major construction materials with post-consumer recycled content Less energy expenditure and pollution Use natural materials to the extent possible as they have low levels of toxicity compared to synthetic materials
