Hi all,

We are looking to certify a new childcare building on a higher-ed campus that will be sharing HVAC systems with an existing childcare building. There will also be an unconditioned, new corridor connecting the two buildings. The existing building will likely not pursue certifications, if its considered a separate building. There is some reno occurring in the existing building, too - but we're talking new door opening, windows, flooring, lighting, casework... The HVAC system will primarily be new, serving both buildings. How do we navigate "reasonable LEED boundaries"? Should these be combined into one "building"? Should the new building boundary stop at the door of the existing building or ignore the corridor? Will this cause energy credit troubles?
