CS-2009 EAp2:Minimum Energy Performance

Undefined Outdoor Spaces and Exterior Lightning

Greetings Everyone I'm working on a office project with outdoor spaces within the LEED Boundary. The project's construction phase is almost finished. Originally this was going to be the only building in the project, but during construction, the owner bought the adjacent land and decided to build a second building which is still on early design phase. Originally a design for the outdoor spaces was made by the architects, but the owner idea is that both building will be part of a same development and will share some of their outdoor spaces. Therefore, the design and construction of some of these spaces have been halted and will resume when the second building's construction begins. This includes the design for the exterior lightning of this space. Since the space I'm speaking about are inside my project's LEED project boundary, but their design will not be defined until some time in the future I don't know how to account for it in this and other credits. Should I exclude this space from the boundary? Should I assume an exterior illumination design that complies with ASHRAE's LPD requirements but doesn't achieve further savings? Should I assume the original design? This situation also affects other credits, and I don't know how to approach it. Any ideas? Thanks in advance for your help.

The boundary issue needs to be resolved for the entire submission before you can determine the appropriate way to deal with it. Two guiding principles to consider - always model the proposed as it was constructed and the baseline in many instances varies depending on the proposed. Ultimately you will need to either exclude it (if possible) or model it as it was finally constructed.

Marcus, thank you very much for your answer, it's been really helpful. Most probably what will do is exclude that area from the LEED boundary for this project, and include it in the LEED boundary for the second building of the development. By the time the second building is finished, construction in the undefined area will also be over.
