Guidelines for Greening Your Concrete Specifications
Suggestions for adding green building related requirements to your concrete specifications are noted referencing the appropriate articles and paragraphs within the MASTERSPEC®
section as a guideline.
For information about AIA's MASTERSPEC contact ARCOM at (800) 424-5080 or visit www.arcomnet.com. Manufacturer and product listings are provided as a starting point. Users are encouraged to research products before specifying. GreenSpec, available at buildinggreen.com, provides a current listing of green building products.
SECTION 07460 -FIBER CEMENT SIDING
PART 1 – GENERAL
1.1 – SUMMARY
B. Related Sections:
1. For LEED Projects – add Division 1 Section ‘LEED Requirements Summary’ for recommendations and requirements for recycled content, regional materials, FSC certified wood, and LEED submittal requirements for all concrete materials.
D. Submittals for Environmental Performance:
1. Provide data indicating the percentage of post-industrial pozzolan cement substitution as a percentage of the full product composite by weight for fiber cement siding.
2. Provide data indicating the source and content for fiber in the product – whether is has been recycled from a post-industrial process or post-consumer use or whether it contains wood from FSC sources.
3. Provide product data stating the location where all products were manufactured and where the raw materials were harvested, extracted or recovered.
4. Provide certification that fiber cement board waste were disposed of properly and construction waste was recycled.
PART 2 – PRODUCTS
A. Fiber-Cement Siding
Consider fiber-cement products which use a high percentage of post-consumer or post-industrial waste wood fiber. Using recycled wood fiber reduces amount of wood waste entering landfills and reduces the environmental impact of extracting new material from forests.
Look for manufacturers which may use a percentage of cement substitution such as fly ash to limit the environmental impact of cement production. Consider fiber-cement products which are made regionally from local resources to limit the energy and environmental impact of the transportation of materials.
Consider sealants, paints, and primers for fiber cement siding that contain low amounts of volatile organic compounds (VOC) to reduce exposure to workers and limit the toxins that contribute to smog.
PART 3 – EXECUTION
Consider methods of minimizing effects of on-site cutting of material which generates silica dust and can be harmful if inhaled. Protect workers and use cutting methods that minimize production of dust and consider vacuum extraction of dust. Design siding to work with manufacturer standard panel and length sizes to limit dust and waste.
