I understand the typical methods for achieving this credit, i.e., underfloor air, etc. And I have documented this on other project (under NC v2.2). But I have a project where the approach may differ from the standard approaches. I have a floor plan with both private offices and an open office plan with cubicles. I do know that for the open office plan with cubicles, we must consider each cubicle as an individual workstation and over the entire scope of the project, the cubicle workstations and private offices must average out to provide control for 50% of these individuals. My particular project is using an overhead VAV system with zone reheat. It does not make sense from economic standpoint and due to space constraints to provide a VAV box for every two individuals in the open office space. However, my project will be using a web-based tool which will allow the building occupants to go online, access the temperature in their space, and make adjustments to fit their comfort level. However, in general, each VAV box serves approximately 4-6 workstations. So the web-based tool would make adjustments to that zone which serves 4-6 people. But since all occupants have access to this tool and the ability to control the zone in which they occupy, would this qualify as controllability for 50% of the occupants? If not, why? And if not, would it qualify under an ID credit? Thanks.
