Technical Bulletin Insulation: Helping to Achieve LEED CANADAñNC Certification Building Materials Technical Services February, 2007 Green and Sustainable Building Programsósing the LEED Rating Tool: U Green and sustainable building programs can impact the design and choice of materials used in a building. The Canadian Green Building Council (CaGBC) promotes green and sustainable buildings through its green programs and rating toolsóLeadership In Energy and Environmental Design (LEED). LEED CANADA-NC is the only tool presently offered by the CaGBC. It applies to New Construction buildings and is based on LEED 2.1 with Canadian modifications and replaces LEED BC. Within LEED, there are 5 major categories where various points can be attained for aspects of the building project (see Figure 1). And, within each category are individual point credits with some categories and/or individual point credits having prerequisite requirements that must be met before points can be taken for the specific category or individual credit. LEED Misconceptionsó LEED does not "certify" products and LEED does not require product "certification" information as product or material submittal verification. It is not necessary to accumulate points in every item under each category in order to amass sufficient total points to meet one of the ranking levels of LEED certification. Individual products have little effect on a category's points (i.e., Materials & Resources) because total points are weighted by the cost of all products used. Table 1 on page 2 lists individual LEED Canada credits for which Owens Corning insulation products may help contribute to achieving the points. Point Distribution By LEED Canada Category Indoor Environmental Sustainable Figure 1 Sites Quality 20% 21% Water Efficiency Materials & Resources 7 % Energy & 20% Atmosphere 24% Technical Bulletin: Insulation Helping To Achieve LEED Canada Certification Table 1 Owens Corning Insulation Contribution to the LEED Canada requirements Note: No single material can obtain points for LEED Certification credits because each category depends on the combined materials and their relation scaled to the total cost in dollars of all materials. LEED Canada Credit Category LEED Canada Requirement Insulation Contribution Additional Comments EA (Energy & Atmosphere) Credit 1: Optimize Energy Performance 1-10 points dependent on % reduction energy use based on MNECB-1997 or ASHRAE 90.1-1999. Insulation contributes significantly to the reduction of a building's energy demand. Global contribution depends on the design RSI value. Project team responsible for the energy analysis concerning the global energy efficiency of the building (ex. LEED standard form letter). MR (Materials & Resources) Credits 4.1 & 4.2 for recycled materials content 1 point 7.5% or 2 points 15% (post-consumer % + 1/2 post-industrial % aggregate weight average recycled contents) for insulation and all other construction materials. Glass batts (Candiac & Edmonton 60+%p-c,0%p-i; Toronto 50+%p-c,10%p-i) Glass bds (Newark 26+%p-i,9%p-c) Foam (15+%p-i,0%p-c). Recycled content certifications by Scientific Certification Systems for foam (>15%) and for glass fibre (>35%). (Abbreviations: p-c = post-consumer; p-i = post-industrial or pre-consumer). MR (Materials and Resources) Credit 5.1 & 5.2 for locally or regionally manufactured materials 1-2 points for products with 80% of mass being manufactured and installed regionally within 800 km radius of project by truck or within 2400 km by rail car for total representing 10% or 20% of all materials. Products from 3 Canadian glass plants and 1 Canadian foam plant may contribute to category points if installed locally. Verify with local sales representative to determine the product's origin. ID (Innovation & Design Process) Credit 1 1-4 points dependent on effectiveness of innovation being applied. The acoustical performance of glass fibre insulation is effective in reducing noise transfer through building assemblies. Credit applicable only when glass fibre insulation is used in acoustical applications.
