I am wondering what the appropriate approach is for a residential multi family project for this credit. Since the LEED EB system is set up for Commercial Buildings and assumes that there are hard surface floors that significant amounts of people are entering upon, we feel that a residential project shouldn't be required to have the same level of entryway systems(10' at every entrance). Our project has about 25 different entrances when you include those through private garages, structured parking, and the many entrances to the individual apartment units in the building (there is about 1 entrance per 6 units in the main buildings, excluding the garage entrances, and the project has about 78 total units). All floor surfaces have carpet on them and have 2'10" grills installed at the entryways. The carpets are cleaned daily by the cleaning staff. I believe the LEED for Homes Rating System requires only 4' entryway systems. Can you provide some advice as to the following:
1) In a residential setting, is carpet and a 2'10" grill acceptable to achieve this credit instead of 10' mats or grills? If not, what is the minimum entryway system we need at each entry?
2) Do we need entryway systems at every one of the 25 or so entrances? If not, how do we determine which entrances do need to have LEED qualifying entryway systems?
Any advice on the correct approach for our project to take would be greatly appreciated.
