color:#1F497D'>Are you sure about your interpretation of the non-tradable surfaces.
If I understand correctly what you are saying is that even though my proposed
design uses less lighting power compared to the baseline for the non-tradable
surfaces I cannot get an benefit from those savings.<o:p></o:p></span></p>

should be less than the overall allowance +5% additional unrestricted
allowance. <o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Each category of tradable does not have to comply prescriptively
and can be higher than base allowance in some cases and have increased savings
in another. For example my overall lighting energy use can be higher for say
parking area compared to the base allowance as long as I compensate that additional
power by increased savings in another category say plaza area.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>On the contrary one has to meet the prescriptive requirements for
each category of non tradable surfaces and cannot exceed the allowance.
Increased building façade lighting cannot be compensated by reduced gatehouse
inspection station lighting.<o:p></o:p></span></p>

I have been modeling Ashrae allowance for non tradable area based on area being
