NC-2009 IEQc5:Indoor Chemical and Pollutant Source Control

And/Or Inside the Building

Dear all, My first question is that which part exactly from the Reference guide states that the entryway system should be placed inside the building? My second question is that should it be (10 ft long and inside the building?) or (10 feet long or inside the building?) as I may understand from the CIR 10098 phrase: "An exception to the 10 ft length and/or indoor location is acceptable ..."

Omar – The “inside the building” entryway requirement is in the EQc5 Chapter of the LEED-2009 BD+C Reference Guide. In that chapter, look in Section 4 Implementation (page 513 of the first edition). After the first paragraph is the heading “Entryway Systems.” In the third paragraph below that heading, the second sentence reads, “Entryway systems must extend 10 feet from the building entrance INTO THE BUILDING INTERIOR.” Therefore, the entryway system must extend at least 10 feet (3 meters) INTO the building. LEED Interpretation #10098 seems to be saying that, if your entry system is at the exterior &/or less than 10 feet long, you will need to write a darned good justification explaining how your alternative approach is every bit as good as (and better than) the prescribed 10-foot indoor system. If you choose to pursue an alternative approach, it might be wise to submit a formal inquiry describing your proposal prior to implementation to confirm that it is acceptable.
