Dear All,
We are looking for a clarification regarding the EQ credit "Interior Lighting" – of LEED V4.1, about option “GLARE CONTROL”.
Do we have the possibility of combining the two requirements between our different spaces for LEED V4.1? that means is it possible to have some of the luminaires which have a Candela /m² between 45 and 90° from NADIR less than 7000 Candela /m² and the other part of the luminaires of the project has a UGR<19?
Because in our project, some luminaires have Candela/m² <7000 and some others is characterized by UGR <19 but its Candela/m² >7000.
We will appreciate your feedback.
Best regards,
Umesh Atre

Hi Sara - This is an interesting question. My first instinct would be yes, a project should be able to use either of the 2 options, so long as they are not being used in the same space. This would a good question for your LEED Coach though, and I would be curious to know what the correct answer is if you wouldn't mind letting us know if you do figure this out. Thanks
