One of our project "Business Centre" is going for CI 2009 ratings system. The project owner is leasing a space in a building and doing the interior layout i.e. lighting , furniture and HVAC. The space will be further leased out to small enterprise or group of 6-7 people. So the majority of equipment that is computers are not in the owner's scope. Do he need to put some mandatory requirements in the sales agreement to meet the prereq and EAc4.0 requirement(50%, 70%-90%of equipment to be energy star) or only the equipment that is in his scope such as projector, kitchen appliance etc need to be considered for this calculation.
