IEQc3.5 - EBO+M

Hi Alyson - Thanks for bringing up these several points. I've tried to address them each separately, in hopes of not missing anything... Statement: Another issue with existing buildings is with previously existing permanently installed walk-off surfaces. This strategy (permanently installed) cannot be earned without manufacturer's documentation demonstrating that the material is designed to effectively capture fine particles. However, it is not requested anywhere on LO; you just have to know to upload it. Be warned--even if you install this new, you must submit a cut sheet of the product. Response: This credit requires entryway systems that are capable of capturing dirt and other particulates as users enter the building. Depending on the project’s climate, some mats may not provide capture dirt and particulates year round, due to reaching a saturation point with heavy rains or snow. Page 454 of the 2009 LEED EOBOM Reference Guide provides criteria for appropriate mats in the second, third, and forth paragraph of Section 4. Implementation. While there is no prohibition on using existing systems - and manufacturer’s documentation is not a required submittal - if a project team submits documentation that appears to show a mat that does not meet these criteria (i.e. a photo that appears to show a standard carpet mat for project in a very wet climate), the Reviewer may request additional information demonstrating that the entryway systems are capable of meeting the credit requirements of capturing dirt and particulates. Statement: Also, this facility alteration DOES NOT meet the EBO+M definition of a 'facility alteration' (per introduction of reference guide) and you cannot claim the purchase or new material or recycle of old material in the materials credits. This is disappointing because one building recently went through the effort to install new walk-off carpet but it did not contribute to MRc3, MRc9, nor IEQc3.5 (because the reviewer asked for cut sheet in final review). Clearly a disappointment to project team. Response: A minimum quantity of facility alteration or addition is required in order to attempt MRc3 and MRc9, to ensure that achieving these credits has a meaningful environmental benefit. Once that minimum is met though, any and all materials used for facility alterations - including the installation of walk-off grates - can be included in these credits. Statement: Really there is no standard for 'carpet performance' and removable mats are never questioned. It seems that a regular cleaning schedule is more important than the type of carpet, but that information is not requested either. Response: Please see above and note that the Credit Submittal Form does request a narrative on the cleaning strategies used by the building. I hope that helps - Megan R/S
