NC-2009 EAp2:Minimum Energy Performance

Exterior Building Lighting Power

Hello, I have a question regarding the Exterior Building Lighting Power. For the project I am working there are a copuple of exterior areas that do not fall in any of the categories of Table 9.4.5 of Ashrae: 1. The perimeter of the project boundary, which has several lighting fixtures. 2. Two sport courts that use several lamps for use at night. Under which category should I include this areas in order to calculate the baseline exterior power allowance? Many thanks in advance, Santiago

Any area that does not fall into a category I would treat as process lighting and model identically. The sport lighting is exempted by 9.4.5-e but must still be included in the models.Perhaps the boundary lighting would be considered a special feature area under the building grounds?

Thank you Marcus, The boundary lighting could be treated as a special feature, but since that category uses the area to calculate the allowed power, it is a bit tricky how to calculate it, which width should I use? For me it seems more reasonable to just measure the whole perimeter length, but then cannot use the special feature area. Would it be acceptable to use the same levels for both models then?

if it does not fit a category I would model it identically in both.
