FAQs about EAp2 :

Our project has a large process load—75%. Despite our efforts to make an efficient HVAC design, the cost savings are minimal. What can we do to earn this prerequisite and be eligible for LEED certification? Is there any flexibility in how we model the p

NC-2009 EAp2:Minimum Energy Performance

light density in wellness center

What space type shall be considered for a wellness center (e.g. for a sauna or for Turkish baths) according to Table 9.6.1 in order to determine the lighting power density for the baseline model? Best Regards

Obviously there is no space type that fits. The illumination levels in those spaces are usually pretty low. One way to approach it would be to find the recommended illumination levels for this space type, then find a similar space type with the same illumination levels that is in 9.6.1 and use that LPD.

If the LPD is very low for this space, and if this wellness center is part of a larger facility that otherwise has matching space types, then you might consider the lighting to be a process load for the wellness space and model both proposed and baseline identically. For a facility where this was a small part of the overall total it may not affect the results to a large degree.
