FAQs about EQc6 :

For Option 1, we would like occupants to be able to control lighting in their area from smartphones, tablets, or computers; we plan to eliminate physical switches altogether. Would this meet the intent of Option 1?

Can I use recessed fixtures and still meet Strategy D?

What lighting controls are required for a conference room with a presentation screen?

Is Option 1 achievable for open office spaces?

Where do I find the CRI of a lamp?

Do task lights need to meet all the lighting quality requirements?

How limiting are the reflectance values in the finish requirements?

Daylight is an important strategy in my project. How do I meet this credit as well as the daylighting credit?

Do operable shades count as lighting controls?

Does having multi-circuit lighting count as providing multiple lighting levels?

How do I calculate an illuminance ratio?

A recessed LED troffer type fixture may have an indirect light component by way of internal reflectors that reflect upward-directed light within the fixture back down onto the space below. Would internal indirect lighting components within the fixture qualify the fixture as a non-direct-only type? As designers, how do we ensure that a supplier’s products (the fixtures) meet the requirements of the credit? Does the supplier need to have an approval from the GBCI for their products in order for them to be used under this credit, option, and strategy?

Hi Geoffrey, yes, I think that these fixtures would be classified as a non-direct-only type. Regarding ensuring that the supplier's products meet the requirements of the credit: there is not a formal definition and approach outlined by the GBCI. Usually the supplier can tell you this information or the manufacturer. Again the GBCI has not provided a formal definition of what is needed here so it's the best judgement and documentation from the designer or manufacturer that would suffice. The supplier does not need to have an approval from the GBCI for their products in order for them to be used for this credit.
