Fully Variable Frequency System Modeling

Hi,

Could anyone kindly help me to make some sense about how to model fully variable frequency air-conditioning system? In this system, most of the components on the water side are fully variable, including chiller, pump and cooling tower. These components work together to make the system operate under "optimized" condition. This is gonna be a LEED project...The envelope is poor, full glass curtain. Lighting system does not have better energy performance compared with the Baseline either. Some "advanced techniques" must be figured out on HVAC side...

Any comments are appreciated.

Thanks Bill. The actual overall window-facade ratio is as high as 66%. The owner targeted a 500lx artificial lighting level in office area without considering natural lighting. I already advised considering daylighting especially since most of the rooms start working at 9am and close at 5pm. Since this office building (over 50,000 sqm) will be open for rent, owner is still hesitate with daylighting sensor installation, because companies which rent the building may not like such sensors...
