<DIV>Here is our perspective on the subject. </DIV>
<DIV> </DIV>
<DIV>Before there was LEED for Homes, you could use LEED NC for multi-unit residential projects - and according to the LEED Guidelines for Lodging one should use 90.2 for residential buildings that were 3 stories or less. But that was then and this is now. So we agree if it is only residential with 3 stories or less than one must use LEED for Homes.</DIV>
<DIV> </DIV>
<DIV>We still use LEED NC for mixed-use buildings of 4 stories or more that include some floors of residential. In this case, we follow 90.1 but follow the 90.1 "residential" aspects of the standard to characterize those floors of the building. </DIV>
<DIV> </DIV>
<DIV>The gray area for us these days is if it is mixed use of 3 stories or less. </DIV>

We<BR>were told by a LEED NC course instructor that the buildings cannot be<BR>certified under LEED NC v2.2. His reasoning is that since ASHRAE 90.1 is<BR>not applicable, the buildings cannot meet EA prerequisite 2. <BR><BR>Also, the LEED NC v2.2 manual states: <BR><BR>"All commercial buildings, as defined by standard building codes, are<BR>eligible for certification as a LEED for New Construction building.<BR>Commercial occupancies include (but are not limited to) offices, retail<BR>and service establishments, institutional buildings (libraries, schools,<BR>museums, churches, etc.), hotels and residential buildings of four or<BR>more habitable stories." <BR><BR>Most standard building codes define 3 story dorms as residential<BR>buildings.<BR><BR>The owners of our buildings have decided to register the projects in<BR>order to get an official credit interpretation ruling from the USGBC. We<BR>hope to have an official answer within the next few weeks. <BR><BR>Regards,<BR><BR>Keith Leadbetter, PE, LEED(r) AP <BR>Pathfinder Engineers, LLP <BR>3300 Monroe Avenue, Suite 306<BR>Rochester, NY 14618<BR>TEL (585)218-0730 x110<BR>FAX (585)218-0737 <BR>kleadbetter@pathfinderengineers.com<BR><BR>-----Original Message-----<BR>From: bldg-sim-bounces@lists.onebuilding.org<BR>[mailto:bldg-sim-bounces@lists.onebuilding.org] On Behalf Of Larry<BR>Degelman<BR>Sent: Friday, January 25, 2008 3:11 PM<BR>To: 'Demba Ndiaye'; bldg-sim@lists.onebuilding.org<BR>Subject: Re: [Bldg-sim] Which LEED with which ASHRAE ?<BR><BR>Standard 90.1 defines "low-rise residential" as " .... multi-family<BR>structures of three stories or fewer above grade...", so 90.1 will not<BR>apply.
