NC-2009 EAp2: Minimum Energy Performance
My turn - a question for those of you who have the SI version of 90.1. Is the lighting power density identical in both versions? For example, stairs in Table 9.6.1 in the IP version are 0.6 W/sf. Is the SI version 6.45 W/m2? Or is it rounded to 6.0 W/m2?

We did not round it up, and used the same number in SI version. We did round it up in previous project, and were asked to changed by reviewer.

Just to be clear - so the SI version in Table 9.6.1 lists 6.0 W/m2 for stairs?

Thats correct marcus. They remove the decimal place entirely. It lists stairs at 6W/m2.
