How many green building listservs are you on?
I’m on only one. And I hope to keep it that way. Talk about volume of email! These people are VERY active, AND extremely savvy about green building. So I won’t cancel my subscription. No way. No how. I just set up an automatic rule in my MS Outlook to put the email in it s own folder. That way, I can glance in the folder at my leisure.
I was going through the folder today and I came across one person’s questions about vinyl siding. What caught my curiosity even further was another person’s share about a movie called “Blue Vinyl” which seems to have something to do with a woman’s battle with a cancer caused by exposure to synthetic chemicals. She is curious about the consequences of putting vinyl on the side of one’s house or in one’s house. (By the way, I’m not endorsing this. I’m just relating how I finally managed to get some good blogging material. It was a bit circuitous in this case.)
So, she’s curious. Now I’m curious. What does LEED say about vinyl if anything? I searched through the new LEED 2009 NC specs and found just one reference to vinyl and that is in EQ credit 4.3: Low-Emitting Materials: Flooring Systems (1 point). Basically LEED is now giving a point for flooring products compliant with the FloorScore standard. Vinyl is listed as one of the products covered by the FloorScore standard.
I read the LEED text. I reread the LEED text. I STILL don’t understand something. Let me show you what I mean:
(All text in GREEN and underlined is newly added text.)
Requirements
All flooring must comply with the following as applicable to the project scope. All carpet installed in the building interior shall meet the testing and product requirements of the Carpet and Rug Institute’s Green Label Plus program.
All carpet cushion installed in the building interior shall meet the requirements of the Carpet and Rug Institute Green Label program. (ADDED) This credit is only available to projects where carpet is installed.
All carpet adhesive shall meet the requirements of EQ Credit 4.1: VOC limit of 50 g/L.
AND
All of the hard surface flooring must be certified as compliant with the FloorScore standard (current as of the date of this Rating System, or more stringent version) by an independent third party. Flooring products covered by FloorScore include vinyl, linoleum, laminate flooring, wood flooring, ceramic flooring, rubber flooring, wall base, and associated sundries.
An alternative compliance path using FloorScore is acceptable for credit achievement according to the following stipulations. 100% of the non-carpet finished flooring must be FloorScore certified, and it must comprise, at minimum, at least 25% of the finished floor area. Potential examples of unfinished flooring include floors in mechanical rooms, electrical rooms, and elevator service rooms
AND
Concrete, wood, bamboo, and cork floor finishes such as sealer, stain and finish must meet the requirements of South Coast Air Quality Management District (SCAQMD) Rule 1113, Architectural Coatings, rules in effect on January 1, 2004. VOC limits are listed below.
• 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
AND
Tile setting adhesives and grout must meet South Coast Air Quality Management District (SCAQMD) Rule #1168. VOC limits are listed below and correspond to an effective date of July 1, 2005 and rule amendment date of January 7, 2005.
• Ceramic tile adhesive: 65 g/L
• Grout and mortar: 250 g/L
OR
All flooring products will meet the testing and product requirements of the California Department of Health Services Standard Practice for The Testing Of Volatile Organic Emissions From Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda.
In an effort to be thorough in understanding these revisions, I went to this page of the USGBC’s website. Here they have links to the NC documents during the Balloting process. On the right, under “LEED 2009Member Ballot Open: View the Current Drafts”, there is a link to “New Construction”. If you click on this link, a folder opens and there will be 2 Excel files inside which show the comments taken about all of the credits. You have to go the EQ tab and scroll down to find comments about EQc4.3.
I didn’t seem to find what I want there.
Here’s my unanswered question:
Does the above text mean that if certain types of finished flooring (i.e. vinyl, linoleum, laminate flooring, wood flooring, ceramic flooring, rubber flooring, wall base, and associated sundries) account for over 25% of the floor space, then 100% of that finished flooring must be FloorScore certified? Otherwise, if the finished flooring is less than 25% of the floor space, don’t worry about the VOCs because the relative off-gassing amount is negligible?
Any insight or experience with this?
When I was reading the comments submitted to the USGBC about the new wording for this credit, I did come across a couple people vehemently stating that this credit needed to be worth 2 points. I had to laugh. I wonder if these comments came from the manufacturers of vinyl or linoleum flooring. Hmm… Suspicious.
