Our CI project won't be occupied until 2015 and the IT and AV equipment schedules aren't yet detailed, just an outline of the power demands for the M&E design is available. We know that the equipment will be specified as Energy Star but at the moment we don't know the exact specification or how much of the equipment will be new - is it acceptable to make a best guess of the equipment at this stage for the design submittal and then update this design stage credit again at the end of construction ?
