cooling a building efficiently

[City_boy12]

Can you cool a sustainable building without using natural ventilation? Is natural ventilation the MOST efficient way of cooling a building?

I might recommend that you check a professional forum - one that I know (disclosure: I work for the company that owns the forum) is HVAC-Talk: http://www.hvac-talk.com/vbb/

They have lots and lots of sub-categories where you can get more specific info.
