OBJECTIVES –Learn about Green Materials: Life Cycle Analysis (LCA) Green Certifications Green Specifications Project Manuals ○ CSI Divisions 1-16 LEED Rating System Green Building Products
What are Green Materials? What is Greenwashing?
What Makes It Green? 1. Where did the material come from? 2. What are the byproducts of the process used to manufacture or produce it? 3. How is the material transported from the factory to the job site, and how will it be installed?
4. How will the material bemaintained and/or operated?5. How healthy are the materials to bearound?6. What will happen to these materialsif and when they are discarded oroutdated? (Can they be recycled orreused?)
What is Green Point Rated? -California grown & community based - Builder, government & non-profit stakeholders - Direct consumer outreach
What is Green Point Rated? Ratings reflect practices ABOVE code in CA Rated in 5 categories with specified minimums At least 50 points overall

Materials & Resources (MR)Credits: 13 Possible Points
Prerequisite 1:Storage and Collection of Recyclables
Credit 1.1: Building Reuse Maintain 75% of Existing Walls, Floors & Roof Based on area Credit 1.2: Building Reuse Maintain 95% of Existing Walls, Floors & Roof Based on area
Credit 1.3: Building Reuse Maintain 50% of Interior Non-Structural Components
Credit 2.1: ConstructionWaste Management Divert 50% from Disposal Based on weight
Credit 2.2: ConstructionWaste Management Divert 75% from Disposal
Credit 3.1: Materials Reuse Use salvaged, refurbished or reused materials such that the sum constitutes 5%, of the total value of materials on the project.Credit 3.2: 10% of total value of materials
Recycled content….. Post-consumer : material generated by end users of a product, which can no longer be used for its intended purpose. Pre-consumer : material diverted from the waste stream during the manufacturing process.
Credit 5.1: Regional Materials Use building materials and products that have been extracted, harvested or recovered, as well as manufactured, within 500 miles of the project site for a minimum of 10% (based on cost) of the total materials value. Credit 5.2: Regional Materials Minimum of 20% (based on cost) of the total materials value.
Credit 7: Certified Wood Use a minimum of 50% of wood-based materials and products, which are FSC certified. These include: structural framing and general dimensional framing, flooring, sub-flooring, wood doors and finishes.
Ecological Functions of aNatural Forest Provides shelter and protection, and maintains stability of air, soil and water. Preserves the perfectly adapted genetic material of plants and animals. Buffers cyclones and tsunamis Absorbs carbon dioxide If large enough, will offer sanctuary to indigenous mammals, birds and reptiles in the event of fire or drought, cyclones or tsunamis, especially if it is linked to wildlife corridors.
What is FSC ? INDEPENDENT – Not-for-profit organization JUST – Balance in decision making between economic, ecological and societal interests. APPLICABLE WORLDWIDE- Criteria implemented in tropical and temperate forests. CREDIBLE – Chain of Custody (CoC) is monitored from forest to end product.Only system that specifies objective, verifiable forest management and closely monitors if these have been achieved.
Cradle to Grave –LCA considers environmentalimpacts related to: Extraction or harvesting of raw materials Refining and manufacturing processes Transportation of those products Eventual disposal or reuse
Look at the whole buildingfrom a life-cycle perspective Addressing the impacts of building operation, including energy use, water use, and maintenance impacts should be a high priority.
Summary of Product Standards for GreenSpec Products made from environmentally attractive materials
Products that are green because of what isn’t there Products that reduce environmental impacts during construction, renovation, or demolition Products that reduce environmental impacts of building operation Products that contribute to a safe, healthy indoor environment:

Advantages of Fly Ash in Concrete Fly Ash is a pozzolan. Fly Ash improves concrete workability and lowers water demand. Fly Ash has a lower heat of hydration. Fly Ash generally reduces the permeability and adsorption of concrete. Fly Ash is economical.
