We have a project that is a mix-used 23,000 SF bldg. The lower story is commercial (8,000 SF) and 2-stories of residential (15,000 SF). The project will follow LEED NC 2009 and will achieve this credit with Energy Modeling
1-How do you model the residential portion, if ASHRAE 90.1-2007 is not applicable to low-rise residential buildings? Appendix G, in the Scope indicates that the provisions are not applicable to multi-family of 3 stories or less.
2-Should we use as a base building the following:
For the commercial portion, use package rooftop units
For the residential portion, use PTAC units?
3-I guess, my other question is, are we allowed to register for LEED NC? due to LEED NC is not applicable for residential bldgs of less than 4 stories? but because the project is a mix-use we could use LEED NC? any advise is appreciated, thanks,
