Good afternoon all, I have a question about LEED certification. We produce high quality water basied paints in Kazakhstan. Our products are certificated by Kazakh Certification Center.

If open plan office is linked with entrance, guest circulation areas and corridors from another zone (which totally takes about 2'000 m2), how we can calculate and predict Reverberation Time?

Hi, I have project where is several open plan offices with different volumes. LEED Acoustic Performance requires T60 below 0.8 sec.
