Hi Marcus,

Please advise me regarding ASHRAE 90.2007 mandatory provision item 9.4.4 which is written as follows:

"All exterior building grounds luminaires that operate at greater than 100 W shall contain lamps having a minimum efficacy of 60 Im/W..."

My question is, "greater than 100 W" is individual lighting or in total? so if my landscape lighting has 30 watt each, and have 10 numbers operate in one circuit control, so in total is 300 W. Do we need to comply the light efficacy 60 lm/watt?

Your answer will be highly appreciated!

Best regards,

A luminaire is an individual light fixture.
