CS 2009 IEQc4.3: Low-Emitting Materials—Flooring Systems

  • What’s simple isn’t necessarily easy

    IEQc4.3The simplest way to meet this credit is to make sure that all your flooring and floor coverings meet the standard designated in the credit requirements. That’s not necessarily easy, because not that many hard-surface flooring products are FloorScore-certified or the equivalent.

    It’s easier to achieve this credit if all your regularly occupied spacesRegularly occupied spaces are areas where one or more individuals normally spend time (more than one hour per person per day on average) seated or standing as they work, study, or perform other focused...

What to include?

Hi
I'm confused about which floors and carpets should be included for this credit. The developer of the project is renting out all spaces to tenants (hotel and offices). This rating system is not suppose to include tenant outfits right? So how do I decide when all spaces are for tenants? For the office spaces I can imagine that I should include the flooring, since they are the same for all offices (exept for some where the floors is left undone). But for the hotel part I'm not sure. Does anybody have any suggestions? Many thanks

Mathilda, on this kind of question I always check C&S Appendix 4 in the LEED Reference Guide.

For IEQc4, it indicates that you need not include tenant space in your CS submission, but that you may do so for EP.

Hi Mathilda,

I agree with Tristan. I would just include the floors and carpets that are included within the developer's scope of work. As Tristan noted, there is an opportunity for Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. if you require the tenants to comply with the EQc4 suite of credits through a binding lease agreement.

Good luck.
Lauren

non-finished flooring for C&S

the project is an office building development, the project proponent would like to leave the feasiblity of installing carpet to the tenants thus the floor will be concrete finish with raised floor when it's handed over to the tenants. Is that eligible to obtain point under this credit? If not, how would it need to do in order to get the point? Is it feasible to bind the use of low VOC carpets in the lease condition?

If there are carpets in other parts of the building, such as the hallways or lobby, you can use those areas to meet the Green Label Plus carpet requirements. If the floors are concrete that have been sealed, that coating would need to meet the South Coast 1113 and would help meet the credit. Those strategies would make this credit very feasible.

I agree with David. As long as the flooring that you do have control over, before the tenants arrive, is meeting the requirements then you'll be in good shape to meet the credit. The LEED-CSv2.0 system used to allow you to get an Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. ID point by requiring your tenants to comply with all EQc4 points. I no longer see this listed as an option under LEED 2009.

Natalie, in the PI forms for a LEED CS project you determine, which areas of the building the owner has control of or not. So you might have control of the flooring in the lobby, elevators, hallways but not in the tenant space. Just make sure you check mark this accordingly. We actually applied for that credit on one of our project. The owner only determined the public part of the building. So you just have to proof compliance with the public part. No need for a lease agreement, only if you really have no areas, which the owner would determine.

Susann, which PI form is the one you are talking about? Where does one have to determine which areas are in control of the original building owner?

Thanks!

PIF 5 Building system control
This lists the systems and also finishes and who has control of what in which area of the building (i.e. main lobby, secondary lobby, build-out, HVAC, Electric, ...). You can select owner, tenant or lease agreement as responsible for determining each.
