For any of you still struggling with passive vs. active space conditioning, here's a helpful flow chart that will assist your decision making process. It comes from a UK publication called " Natural Ventilation in Non-Domestic Buildings".
Incidentally, 30 - 40 W/m2 translates to 2.8 - 3.7 w/sf. Typical internal loads in an office building are 1.5 -2.5 w/sf before any envelope gains are included, so your building has to be pretty efficient to have any chance of making it work.
I will have "office hours" next Wednesday afternoon (9/5) from 2PM to 6PM EDT. If you wish to meet with me via phone, send me an email with your preferred 30 minute block.

What is comfort cooling?
In the UK, designers distinguish between "full air conditioning" which includes tight control of temperature and humidity (think museums), and comfort cooling, which allows greater variation in temperature, and limited humidity control.
