[Bldg-sim] chiller cost

I am looking for the cost of a scroll chiller.
Does anyone has some indication, either on a 
per ton basis, or comparatively to other chiller's type?

  Wade,
   
  Look at the method using daylight factors.  Your physical model has to create results for several sun angles and an overcast sky - please refer to the DOE-2 manual for more details.

    I see from the thread that this question may have gone unanswered in the past.  I'll give it a try anyway.

    I know that PowerDOE is not explicitly capable of modeling light shelves for daylight dimming measures.  However, has anyone had any success manipulating a model to get reasonable approximations?  I have results from a physical model that I can use to calibrate my methods, but I'm not sure where to start.

    Many thanks in advance for your help.
