Are there any alternative requirements for Lighting Comfort criteria for Class 2 buildings in Green Star Buildings?
The simple answer is yes. Class 2 buildings targeting the ‘Lighting Comfort’ and ‘Glare from Light Sources’ criteria in Green Star Buildings can use the below criteria to meet credit compliance:
- Have a Minimum Colour Rendering Index (CRI) 85
- Be consistent for the colour selected, demonstrated through a Standard Deviation Colour Matching (SDCM) of 3 or lower.
- All luminaries must not produce unwanted glare and achieve a Unified Glare Rating (UGR) of less than 19 for living, dining, kitchen, bedrooms & bathrooms. For all other areas a UGR of less than 22 is acceptable. Information can be found on the manufacturers datasheets or by requesting it.
- All luminaire control gear must meet the requirements in IEEE 1789-2015 as either being ‘Low Risk” or “No Observable Effect”
All other spaces (classified by NCC) present in the building meet the requirements as per the Green Star Buildings v1 submission guidelines.
