Hello, I have a technical question about the credit Daylight for a Museum (with art galleries, offices, restaurant).
The project team claims that we shall never have more than 150LUX (daylight+artificial light) in the art galleries for conservation purpose.
However the credit Daylight requires a minimum of 300LUX of daylight in order for a space to be compliant.
What are the exemptions for art galleries since it is not specified in the Reference Guide?
Can we exclude these spaces from the calculation or sets lower limits ?

Hi Marilou, I was just looking at my v3 occupied space matrix (If you look in the EQ overview here, it doesn't list Museum yet, maybe another thing to ask GBCI about directly). Museum galleries are listed as regularly occupied for the Daylighting credit and require the space to be counted. What the EQ overview does specify is that the length of time of a regulary occupied space is "sufficient to affect the person's well-being, and she would have an expectation of ...control over the environment." That leads me to believe maybe a gallery could be omitted, but without checking with GBCI, I'm not 100% sure. I would recommend contacting GBCI or attempting a CIR. Before that, perhaps suggest to the project team that maybe the light levels can be higher, but just more diffuse? Hope that helps.
