Question-and-Answer Resource for the Building Energy Modeling Community

Is the project pursuing LEED v4? For LEED 2009, ASHRAE 90.1-2007 applies - no System 9. For ASHRAE 90.1-2010, System 9 only applies to heated only storage facilities, not for an office building. If the building is heated only, you still have to model a cooling system based on the 90.1-2010 System type. 90.1-2007 stipulates the same requirement - cooling is to be modeled even if there is no cooling in the proposed design.
