[Bldg-sim] Swimming pool lighting with 90.1

[Nicholas Caton]

Hi Julien,



For either case, and even if the pools are interior to the building, I
would consider citing “Lighting for swimming pools and water features” is
under the exempted list for exterior lighting power calculations under
90.1-2010, and more broadly “athletic playing areas” under 90.1-2007.



Evoking that exception, you could

A)     have the baseline match the proposed (for a PRM model),

B)      omit that lighting power entirely (for demonstrating prescriptive
compliance), or else

C)      the stage is then set for you to differentiate from the baseline by
demonstrating how your design saves energy relative to “standard” pool
lighting by way of separate/exceptional calculations.



If you want to wrap into your interior LPD regardless,

1.       Gymnasium/Sports Arena/Exercise Center seem to be the likely
candidates for BAM.

2.       Class I through Class IV comes from IESNA Handbook/RP-6, and is
used to differentiate illuminance recommendations based upon the degree of
competition (ranging from professional/national at Class I down to
amateur/recreational at class IV).  I’d suggest having your lighting
designer determine which set of illumination recommendations best matches
the photometric calculations for pool surface/deck surface illumination.

Hello,



I have two concrete cases where I’m embarrassed regarding lighting in a
swimming pool with 90.1.



*Case 1 : A swimming pool building (the building  is a swimming pool)*

In the lighting section of 90.1, the Building Area Method (9.5) has no
building area type corresponding specifically to a swimming pool. My guess
would be to choose the “Gymnasium” because as a swimming pool, there is
high ceiling and locker room.



Using the Building Area Method, is the “Gymnasium” a correct assumption for
a swimming pool building ?



*Case 2 : A swimming pool in a residential building*

  Assuming that the “multifamily”’s LPD doesn’t allow me to  comply to the
Building Area Method, and I decide to choose the space by space method. My
guess would be to choose a building-specific space type in the list “Sport
Arena”, but I’m block by these unanswered question
<http://energy-models.com/forum/energy-modeling-software/trace-700/leed-and-ashrae-901/lighting-power-density-space-space-meth>
: what is the meaning of the class ? :

·         Court sport arena – class 4

·         Court sport arena – class 2

·         Court sport arena – class 1



Using the Space by Space Method, what would be the best building-specific
space type for the area dedicated to the pool ?





Thanks,



Julien
