The Illuminating Engineering Society of North America has recently added Position Statements to their listed of documents they publish. The intent of the position statement is to issue relevant industry information quickly, until further documentation is ready.
The first position statement (PS-01-09), titled Integrated Building Design, reflects the societies’ support of this design approach.
The second (PS-02-09), titled Use of Spectral Weighting Functions for Compliance with IES Recommendations, clarifies IES’ position regarding scotopic/photopic weighting of illuminance recommendations.
I am impressed by the Society’s desire to better react to the needs of their membership.
