Room Geometry Adjustment - Clarifications

[GoogleCodeExporter]

What 90.1 PRM Section(s) are relevant to this issue?

3.4.3 Interior Lighting - Room Geometry Adjustment

Explanation of issue:

A) Is application of the Room Geometry Adjustment Automatic, or does the user 
need to explicitly indicate that it is to be used.

B) Eligibility for the room geometry adjustment to lighting power is calculated 
as a function of luminaire mounting height and workplane height.  Are either or 
both of these values user editable, defaulted as a function of some other 
property, or prescribed?

Luke,
for the NACM- is the tailored lighting illumination height a user input? The 
ACM document specifies it to be so but I cannot find it on the UI

Hi Supria,
I'm on the road today and tomorrow, so I'll keep it short...

In order to use a user input (instead of the ceiling height, which is the
default), you need to utilize the interior lighting system input
methodology.  The input for luminaire height, as well as other detailed
inputs ( PAFs, allowances, etc) are at the interior lighting system screen.

A) the application of room geometry adjustment isn't automatic. A user would 
need to specify if a space qualifies for it.
B) Work plane height and mounting height need to be user inputs (shown if a 
user states that a space qualifies for RCR adjustment)

Couple of questions-
1. Luminaire types at present are very restricted- how would a user specify 
LED/HID etc. luminaire types?
Are there any plans for adding additional types for lighting?
2. User input for RCR eligibility, work plane height and mounting height should 
also be added for LPD input for spaces.

Question 1:
The current list of luminaire types (v3) is:

  LinearFluorescent
  CFL
  Incandescent
  LED
  MetalHalide
  MercuryVapor
  HighPressureSodium

Are there additional lighting types that you would prefer to add (these are 
fairly easy to add).

Question 2:

We should probably review the approach for providing lighting inputs before 
identifying a final solution...

Based on discussion with Luke, we'll go ahead and add capability for room 
geometry adjustment (check box to ask a user is the space is eligible as well 
as user input for mounting height and work plane height) and all additional 
controls in the ILS screen. 
For a user specifying lighting input through LPD input, these additional 
credits wouldn't be available.

The capability to specify input for additional lighting allowance as well as 
room geometry adjustment will be added to the LPD input in Phase II

For all mandatory controls, we'll follow the Title-24 approach where it is 
assumed that the lighting schedules reflect the presence of all mandatory 
controls.
