S MR 4 Recycled Content Do not contribute The from PRELCO INC.. consists of a glazing on which has been deposited, a geometric pattern or any images in opaque or translucent ceramic. Use materials with recycled content such that the sum of post-consumer recycled content plus 1/2 of the pre-consumer content constitutes at least 10% (1 point) or 20% (2 points) based on cost of the total value of the materials in the project. This product does not contribute to Credit MR 4 because it does not contain pre-consumer and post-consumer recycled content. MATÉRIALS AND RESOURCES (MR) The recycled content value of a material assembly is determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value. MR 5 Regionals Materials Do not contribute It's important to specify that some glass industries report that their products are up to 20% recycled content, but it is usually come from internal residues. It this a healthy waste management, not a preconsumer recycled content, as defined by the Federal Trade Commission. Use building materials or products that have been extracted, harvested, recovered and processed within 800 km (500 miles) (2,400 km if shipped by rail or water) of the final manufacturing site. Demonstrate that the final manufacturing site is within 800 km (500 miles) (2,400 km if shipped by rail or water) of the project site for these products. If only a fraction of a product or material is extracted, harvested, recovered, processed and manufactured locally, then only that percentage (by weight) must contribute to the regional value. The minimum percentage of regional materials for each point threshold is 20% (1 point) or 30% (2 points). The from PRELCO INC. cannot contribute to this credit since of its components are extracted, collected, treated and recovered more than 800 km or 2,400 km radius (depending on the transportation mean used). The percentage calculation was performed by considering the requirements of Credit MR 5 and the maximum distance radius (which depends on the means of transportation used). The origin of the main components and the mean of transportation used must be validated for every project. The final manufacturing site for the from PRELCO INC. is located in Quebec, Rivière-du-Loup (G5R 2M9). PRELCO INC. has all required documents regarding LEED and provide information for a specific project. PAGE 4
S Low-Emitting Materials: Paints and Coatings IEQ 4.2 Non applicable Paint and coating used on the interior of the building (i.e., inside of the weatherproofing system and applied on site) must comply with the following criteria as applicable to the project scope: Anti-corrosive an anti-rust paints applied to interior ferrous metal substrates must not exceed the VOC content limit of 250 g/l established in Green Seal Standard GC-03, Anti-Corrosive Paints, Second Edition, January 7, 1997. INDOOR ENVIRONMENTALQUALITY (IEQ) Clear wood finishes, floor coatings, stains, primers, sealers, and shellacs applied to interior elements must not exceed the VOC content limit established in South Coast Air Quality Management District (SCAQMD) Rule 1113, Architectural Coatings, rules in effect on January 1,2004. Daylight and Views: Daylight 1 point To provide for the building occupants a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building. Through 1 of the 4 options achieve daylighting in at least 75% of the regularly occupied spaces. Points 75% 1 95% exemplary performance 1 additional point with Credit ID 1 path 2 The Credit IEQ 4.2 only applies to paints and coatings used on-site and on the interior of the building (inside the vapor barrier). The paints and coatings used in the manufacturing of PRINTED GLASS PREL-DESIGN from PRELCO INC. are factory-applied and thus don t have to meet the requirements for this credit. Special attention should be paid to any on-site application of paints or finish products for touch ups. The products used must also meet this credit s requirements. Indirect Regularly occupied spaces IEQ 8.1 Option 1. Simulation Option 2. Prescriptive Option 3. Measurement The Credit IEQ 8.1 is related to the value of visible light transmittance (VLT) and window-to-floor area ratio (WFR). The building design and the selection of glazing remain crucial elements for achieving this credit. Maximize the contribution of daylight in a building can reduce the use of electric lighting while promoting the well-being of occupants. Several strategies can be envisaged to optimize the distribution of natural light entering through the perimeter glazing. Thus, the addition of glass doors, interior windows, pieces of furniture or railings tempered promotes the circulation of natural light without compromising the safety of users. In addition, the use of patterned glass also helps counter the glare caused by sunlight while preserving the privacy of the occupants. PRELCO INC. is able to advise you at the time of selection of glazing as well as providing all the necessary documentation for this credit as part of a LEED project. Option 4. Combination PAGE 5
S INDOOR ENVIRONMENTAL QUALITY (IEQ) IEQ 8.2 Daylight and Views: Views 1 point Indirect Achieve direct line of sight to the outdoor environment via vision glazing between 0.76 metres and 2.3 metres (30 inches and 90 inches) above the finished floor for building occupants in 90% of all regularly occupied areas. Determine the area with direct line of sight by totalling the regularly occupied floor area that meets the following criteria: In plan view, the area is within sight lines drawn from perimeter vision glazing. In section view, a direct sight line can be drawn from the area to perimeter vision glazing. Several strategies can be considered to maximize the direct line of sight to the environment of a building. According to the conception and design of printing, the use of interior windows, glass doors, pieces of furniture and railings preserve sight lines offered by the perimeter glazing. The glasses can be printed in whole or in part patterns or opaque or translucent images according to the desired level of transparency. PRELCO INC. is able to advise you at the time of conception as well as providing all the necessary documentation for this credit as part of a LEED project.
