Inquiry

This CIR is being submitted to assess whether this proposed ID credit may qualify for a point assuming that all proposed standards are met and all documentation is made. ID Credit Title: Low-Emitting Exterior Materials: Paints and Coatings Narrative Statement of Credit Intent: Reduce the quantity of air contaminants that are odorous, irritating, and/or harmful to the comfort and well-being of installers. Increase the demand for Low VOC materials for exterior applications. Narrative Statement Describing Credit Requirements: Paints and coating used on the exterior of the building shall comply with following standards: Architectural paints, stains and coatings. Do not exceed VOC limits set by Green Seal Standard GS-11 - Flats - 50 g/L - Non-Flats / Primers - 150g/L Anti-corrosive paints, stains, and coatings. Do not exceed VOC limits set by Green Seal Standard GS-03. - 250 g/L Clear wood finishes, floor coatings, stains, and shellacs. Do not exceed VOC limits set by the South Coast Air Quality Management District (SMAQMD) Rule 1113 - Clear wood finishes: varnish 350 g/L; lacquer 550 g/L - Floor Coatings: 100 g/L - Sealers: waterproofing sealers 250 g/L; sanding sealers 275 g/L; all other sealers 200 g/L - Shellacs: clear 730 g/L; pigmented 550 g/L - Stains: 250 g/L Narrative Describing Project\'s Approach to the Credit: Require all exterior paint applications to meet the same standards as for interior paint applications. Exterior paint applications will include but are not limited to exterior hollow metal doors, soffits, fascias, metal roof touch-up, metal cap flashings, metal lintels, and vent grating. The coating for our metal roof will be a factory applied finish.

Ruling

The strategy proposed for earning an Innovation in Design credit for Low-Emitting Exterior Materials: Paints and Coatings has merit. In order to achieve this credit, the approach must be comprehensive in nature and include VOC limits for concrete sealants and caulks, exterior paints, wood stains and sealers, and metal stains and sealers. Please refer to the LEED NCv2.2 IDc1.1 CIR ruling dated 10/23/2006 as well as LEED EB: Operations & Management SSc2 for further guidance on how to approach this credit in a comprehensive manner. The first item in the Materials Selection section of the LEED ID Credit Catalogue (Page 19) offers general guidance for VOC content in material selection when applying for an ID credit.
