Our Consultants can fully participate in the early stages of your design of your LEED seeking projects by helping you to proactively prepare the necessary supporting documentation of how our products and processes meet the referenced standards applicable to the following LEED® credit points:
1. Sustainable Sites:
Credit 7.2 Heat Island Effects: Roofs: 1 point
Includes one (1) point for roof surfaces with Solar Reflective Index (SRI) of 78 for low slope roofs (< 2:12) and 29 for steep slope roofs (> 2:12) for a minimum of 75% of the roof surface. Vicwest has prepared the necessary documentation on the SRI of our various paint colours for this credit.
2. Water Efficiency: up to 5 points
All of the credits within this category can be achieved with on-site water harvesting. The LEED® reference manual states:
Specify and install a roof-water or groundwater collection system. Use metal, clay, or concrete-based roofing materials and take advantage of gravity water flows whenever possible. Roofs made of asphalt or roofs with lead-containing materials contaminate collected rainwater and render it undesirable for reuse.
Please note that this captured water from our metal roofing products can only be used for non-potable purposes.
3. Energy and Atmosphere:
Prerequisite 2, Minimum Energy Performance
Credit 1, Optimize energy Performance:
The amount of points available in this credit category, combined with the prerequisite for optimum energy performance, stresses the importance that LEED® imposes on energy efficiency. Generally, the first consideration for upgrading any potential building’s energy efficiency starts with the building envelope.
A significant contribution to this credit category is available through the use of our insulated metal panels for the building envelope with R-values of 7.7 per inch of thickness with no thermal bridging and low air infiltration rates.
Buildings built to the LEED® Standard must reduce energy consumption as established by the MNECB by 25% or reduce energy costs by 18% as established by ASHRAE 90.1
Additionally, the foam core insulation of Vicwest’s insulated metal panels is CFC and HCFC free an extra eco-friendly feature, however not a LEED requirement. The blowing agent that we are currently using in the production of our Insulated Metal Panels is Pentane. Pentane has zero ozone depleting potential and the least global warning potential of any blowing agent currently on the market.
4. Materials & Resources:
Credits 2.1, 2.2 Construction Waste Management: up to 2 points
Given that our steel products are fully recyclable, it is conceivable that ALL our waste material will be recovered from the construction site and recycled.
Credits 4.1, 4.2 Recycled content: up to 2 points
Our steel products contain 23% post-consumer recycled content and 7.6% pre-consumer recycled content.
Credits 5.1, 5.2 Regional Materials: up to 2 points
Because we ship our finished products to our customers by truck, this determines the limiting distance for both the extraction of the raw material and the point of manufacture to 800km from the job site for these credits. While in many cases our manufacturing facilities will be within this limiting distance, unfortunately, our steel suppliers’ mine sites for virgin ore fall outside this required range for our customers to collect these credits.
Credit 8 Durable Building: 1 point
The intent of this credit is to minimize material use and construction waste over a building’s life resulting from premature failure of the building and its constituent components and assemblies that conform to the principles outlined in CSA S478-95(R2001) Guideline on Durability in Buildings.
By virtue of our extensive experience in terms of engineering, detailing, rain-screen principles and best practices for installation, Vicwest can assist a consultant team from the initial stages of design to ensure that the project’s metal building envelope will meet its expected service life.
Our paint finishes have film integrity life expectancies of 40 years. On site recoating of weathered finishes is a viable option to extend the finish, therefore avoiding the need for replacement of full panels. However, should replacement be the only alternative, the screw-down fastening of our products lend themselves to disassembly.
5. Indoor Environmental Quality:
Credit 4.1 Low-Emitting Materials: adhesives and sealants 1 point
All adhesives and sealants must comply with standards of the South Coast Air Quality Management District, Rule #1168. For Architectural Sealants, the maximum limit is 250 grams/liter. Your Vicwest representative can ensure that the sealants that constitute a component part of our metal building product assemblies comply with this requirement.
Credit 4.2 Low-Emitting Materials: paints and coatings 1point
This Indoor Environmental Quality credit applies primarily to products and installation processes that may adversely affect indoor air quality within the weatherproofing layer of the building envelope. As a building envelope manufacturer, our products will more than likely be used outside the weatherproofing layer of the building envelope. While projects should strive to limit the use of VOC-emitting materials on the building exterior or the project site, their use is not addressed under this Credit.
However, if our steel profile products (for example our L800 liner panels or our Insulated Metal Wall Panels) will be the interior finish of the building you will need to account for the following:
The paint finish: Valspar states that its WeatherX paint finish does contain solvents but because the paint is applied and fully cured in the manufacturing environment, all VOC’s from the paint are captured at the factory thereby eliminating any off-gassing of the paint from our painted metal products at the job site.
The sealant: our L800 Liner Panel and Insulated Metal Panel products use a factory applied bead of sealant to the liner side of the panel and these installations will also require field applied sealant to the structure and as a marriage bead to our factory caulked liner. The sealant that we use for these applications is compliant with South Coast Air Quality Management District (SCAQMD) Rule #1168
6. Innovation in Design:
Credit 1.1 to 1.4 Innovation in Design up to 4 points
The intent of these credits is to provide design teams and projects the opportunity to be awarded points for exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative green building strategies not specifically addressed under the current LEED rating system. Your Vicwest representative can work with you to develop your innovative or exceptional ideas regarding our products
