We are developing a contraction village that will house contractors for the adjacent new development. The construction village will have accommodation units and support facilities (e.g. recreational buildings, retails, etc.) Regarding LEED ND: GIBp2, for buildings used only of contractor accommodation, does it still needs to comply with LEED BD+C Homes prerequisite: Minimum energy performance or it falls under LEED BD+C New Construction?

If the residential buildings are single family homes, they would need to qualify for the energy pre-requisite of BD+C Homes version 4. If the residential buildings are low-rise, multi-family buildings 3 stories or fewer, they would need to qualify for the energy pre-requisite of BD+C Homes Multifamily Low-Rise version 4.
If the residential buildings are 4 stories or higher, they would have to comply with the energy pre-requisite for either BD+C Homes-Multifamily Midrise v4 or with BD+C New Construction v4.
The non-residential buildings (retail, recreation, etc) would need to comply with BD+C New Construction v4.

Hi David,
Thank you for your response.
What is the definition of 'Single family homes'? The accommodation units will house construction workers. One dwelling unit will have max of two construction workers. Also, all of the accommodation units are provided by the developer.
Does this still falls under the definition of 'Single Family Homes'?
Thanks,

For LEED, the definition is based on the building form and it's mechanical, electrical, and plumbing systems, not by who lives there. In this context, "single family homes" usually means a detached, stand-alone house. For LEED Homes, I've heard the "single family homes" definition can also be applied to row houses or town houses where each house is physically separated from the attached neighboring houses by a solid wall, or "party wall" and each home has it's own independent HVAC and water heating equipment.
If the dwelling units are physically attached to each other, and share some part of the heating, cooling, ventilation, or hot water system, and are one, two, or three stories then it's considered Multifamily Low-rise.
But in the end, whether the dwelling units are considered single family homes or multi-family low-rise may not matter, as both building types would follow the same energy pre-requisite -- Energy Star for Homes version 3, using a HERS Index rating. There's just one "LEED Homes" rating system for single family homes and low-rise multifamily buildings, Sorry if I made it sound like those were two different rating systems.
