[BLDG-SIM] T-24 question in eQuest for California project

[Renee Azerbegi]

Greetings,
 
For those who have used the Title 24 analysis in eQuest for California projects, I know it hasn't been officially approved yet but by the time our building will be fully designed I am hoping that it will be. Anyone know the latest on this approval process?
 
Also, during early design stages, we typically run a Base Case (code complaint model), a Design Case (proposed design), and EEMs (energy efficiency measures) on top of the Design Case to determine savings individually from each EEM.
 
When we run the Title 24 analysis, a T24 Standard model  is created  which is great so we don't have to input all the data ourselves. However it also creates a T24  Proposed Design model. Obviously the T24 Standard model is our new Base Case.  However, the T24 Proposed model is sometimes quite different than our  original Design Case.   Does anyone know why the simulation changes our Design Case to make the energy usage different?
 
Also, we had trouble with the daylighting simulations in  adding daylighitng to the Proposed T24 design  case. I'm assuming it is correct to model the EEMs on top of the T24 Proposed Design? But how do we get around the daylight modeling part?
 
This building is  going for LEED complaince. The new LEED version if you haven't heard, for those that work on LEED projects in California, isn't giving any additional credit for T24-2005 compared to ASHRAE 90.1-2004.
 
Thanks for any help! This is the first time we are using this T24 compliance analysis tool.
