Hi, we are working on a

Per LEED ND v2009 (see pg 471 of Reference Guide), the term "Planned Occupancy" states, "The minimum planned occupancy for multiresidential buildings is 1 person for a studio unit, 1.5 persons for a one-bedroom unit, and 1.25 persons per bedroom for a two-bedroom or larger unit." As for calculating visitors, we found this note someone posted for PIf3 on LEED User: "There's no hard-and-fast rule for estimating visitors. You could survey some building management companies, or you could just make an assumption such as 1 per 10 units."

On the other hand, LEED-NC v2009 Ref Guide p53 (SSc4.2) and p170 (WEp1) direct that one should assume 2 people for a 1-bedroom, 3 for a 2-bedroom, 4 for a 3-bedroom unit, etc. They don;t meantion studios, so maybe 1 occupant could be used there, to referring LEED-ND.
