Dear Marcus
We conducted an energy simulation analysis and included Facade lighting as one of the energy saving features. One of the LEED Review comment is that because Facade lighting maximum LPD is under 'non -tradable', it must be modelled same for 'Proposed' and "baseline'
Can you confirm this and What is the rational behind this.
Does this mean that however efficient the facade lighting is, and even if it goes beyong baseline, it cannot get any points
Hope for your clarification and appreciate it

That is how LEED projects are reviewed. Only the tradable exterior lighting can be used to claim savings.
It has to do with the fact that exterior lighting is a mandatory provision and the nontradable surfaces cannot be traded to meet the mandatory provision.
So yes better than code facade lighting does not contribute to the savings for LEED projects.
Not sure I agree in principle but that is how it is being applied.
