We are working on a multifamily building with naturally ventilated interior kitchens located next to the living/dining rooms that have operable windows. The kitchens meet 62.1-2007 section 5.1.1, having unobstructed openings to the living/dining rooms exceeding 8% of kitchen area and 25 SF. However, IEQp1 form v5.0 doesn't have a table where these rooms can be entered. There is a table for naturally ventilated rooms within 25 feet of operable windows, but not for the interior rooms that are ventilated through adjoining rooms. How can these areas be represented in the LEED form? Thanks.

Are the kitchens themselves also within the 25'?

Joseph, the kitchens themselves aren't within 25 feet of the windows. From the wording in Section 5.1.1, it doesn't seem it's required that the interior rooms need to be within 25 feet, but do you think that is a requirement?

Erika, I have always considered the language to mean that all spaces must be within the 25'. I have seen LEED review comments that agree with this interpretation.

Erika, I am in agreement with Andrew. The way I see it is that it wouldn't totally make sense if an "adjoining room" outside 25' could comply, but spaces beyond 25' within the same room wouldn't comply because they were beyond 25'. I too have seen reviews where this was interpreted like this.

Joseph, Andrew, thank you for your responses. I do have some interior rooms that are within 25' from the window, how would those be entered in the LEED form? I am thinking of entering both the interior room and it's adjoining room with the window as one large room in Table IEQp1-A5 and provide a narrative explaining that they are two separate rooms. Do you think I can submit something better?

I think that would be fine as long as you have the narrative. Remember that you are sure to get a comment along the lines of "The 25' dimension may not be impeded by walls." I always upload a plan showing a dimensioned line from the openable area to the furthest occupied corner.
