Standard reference for Canadian projects

We also have a project in Ontario and would be interested in any response you get on this.  Please post any feedback you get from review.  thanks.

We also had this doubt. When you receive the response, please post it.Thanks.

We had the same question and  others.  If it helps I will post the GBCI response here--note #2:

Thank you for contacting GBCI regarding glass to use for SSpc 55 Bird collision deterrence <https://www.usgbc.org/credits/new-construction-core-and-shell-schools-new-construction-retail-new-construction-healthca-44?return=/credits/New%20Construction/v4>.

1. Testing that is recognized is noted in the guidance, Bird Collision Deterrence: Summary of Threat Factors <https://www.usgbc.org/resources/bird-collision-deterrence-summary-threat-factors>. If a manufacturer claims a different result for a similar non-tested product, I would ask them to demonstrate that.

2. There are no municipal standards that can be used for this credit.

3. The listed frit patterns are those with a 20 and 40% coverage. The ones you are asking about would appear to be a much lower percentage, therefore a higher threat factor.

I hope this information helps you get started. If you have additional questions or concerns, you may respond directly back to this email.  For future inquiries, please contact us at <www.gbci.org/contact>.

ORIGINAL INQUIRY:
Our team is pursuing this Pilot Credit for our project. The online credit language for LEED v4 and v4.1 provides helpful guidance, including a Threat Value spreadsheet listing of glazing characteristics and their tested or inferred threat values. They are also looking at Ornilux by Arnold Glass, which is a UV coating with a "Mikado" pattern as a possibility, but with much higher cost. Recommended design phase analysis includes identifying the manufacturer's "Reflected Light Out" rating for the glazing product, contrast/visibility of the pattern, and site conditions that may contribute to reflections.

The team architect has noticed that one manufacturer's product meeting the description of a frit pattern on the spreadsheet had a TRV of about half that listed on the spreadsheet. I suggested they look at the reflectance and surface layer for the frit to see if the TRV varied, since they also impact the threat value.

We have a design presentation for this project in one week and were looking for additional guidance for finding suitable products to present to the Owner for this building which has a substantial amount of glazing in certain areas. 
For example, certain municipalities have established standards SF, NY & Toronto as acceptable protection systems for buildings. If a product meets these standards, will it be an acceptable alternative?
Specifically, the team wanted to find out if either of these were acceptable (I suggested without knowing the glass surface layer and reflection of the project, it may be impossible to know, but want to confirm--also I believe that the dot size would not provide sufficient pattern, based on the spreadsheet information):
(a) White 1/8"dia. Dots (acid etched or fritted) in a 2" x 2" pattern
(b) White 1/8"dia. Dots (acid etched or fritted) in a 2" x 4" pattern

Please provide responses to these:
1. Besides Reflected Light Out, are there other available product certifications, standards or testing that can be met to identify TRV for products, especially when they are not listed on the spreadsheet?
2. Are there any municipal standards that are acceptable?
3. Can you comment on (a) and (b) above?

We are also reaching out to ABC. 

It would be a whole lot easier if they'd align with the ABCs recommended Prescriptive Codes. https://abcbirds.org/glass-collisions/existing-ordinances.  There is too much ambiguity in the credit at this point.
