Schools-2009 EAp2:Minimum Energy Performance

Task Lighting

Dear all, I received the following review comment for my school project: "Tables EAp2.4 and EAp2.5 report consumptions for process lighting for both cases, but it is unclear what lighting has been included in this category and what exception(s) to Section 9.2.2.3 apply. Please provide descriptions of the lighting included in this category and which exception has been used, or revise the models as required. Keep in mind that Section 9.6.2 no longer includes an additional allowance for task lighting when using the Space by Space Method and that task lighting is not considered a process load." 1) Does anyone know of examples on what type of lighting may be included in process loads? 2) Does this mean that I need not worry about task lighting for all LEED projects? Many thanks,

All of the Exceptions to 90.1 Section 9.2.2.3 are considered interior process lighting. No, task lighting must be modeled if it is in your project. It is not usually considered process lighting and should be included in the overall lighting for the Proposed model.
