[Bldg-sim] 90.1-2007 Exterior Lighting Allowance calculation

[Duggin, Cory]

I agree with Nick, and I have done this many times.  If there is separate canopy lighting from the entry door lighting, you can claim both.

My view is that claim both allowances are technically not allowed, even in the case indicated by Nick. However, it is difficult for the reviewer to check for this in most cases (such as if there are both doors with and without canopies, it may not raise a flag that both allowances for doors and canopies are included).

________________________________



Not to be contrarian, but I think there are cases where you can reasonably claim both allowances.

If you have a large illuminated/illuminating canopy connecting to a building entrance, such as with a with many hotel drive-up lobbies, and that canopy's lighting is illuminating (directly or indirectly) a substantial ground area separate from the main entry landing, then it would be appropriate to claim both allowances.  I would not claim canopy credit for smaller canopies at entrances which only pool light on the vertical entryway and/or the landing area.

This falls squarely into the logic and guidance that allowances may only be claimed for illuminated surfaces - you cannot claim façade lighting when it does not exist in the proposed design, for example.

If there is a hard rule disallowing this practice, I would submit I have yet to run into it with any reviews.

Regards,

~Nick

Hi Christopher,

You are only allowed to include the allowance of one or the other surface type (i.e. entrance or canopy/overhangs). You can pick the one that is the most beneficial, but you can't include both.

Table 9.4.5 includes allowance for Building Entrances and exits (W/linear feet) and Canopies and Overhangs (W/ft2).  If a door has a canopy do you include the allowance for both the W/linear feet and the W/ft2 of canopy?

Thanks for any insights!
