    I am glad to see that 125volt power options as they relate to the building space and modular furniture have been addressed under occupancy driven energy controls. With almost every device drawing power in a continuous state the energy vampire problem is long overdue to be addressed. Section 8.4.2 does have potential large implictions on design for both the building architect and modular furniture manufacuters. What time line has been given for adoption of the principle and when is the compliance deadline. I thank you for all you help with this.

      In NYC, ASHRAE 90.1 is accepted as an alternate reference standard; NYC Energy Conservation Code compliance for new work is currently required.
