[Bldg-sim] Query on Grow lights green house area.

[Javed Iqbal]

Hi Ashish,


   - You can't claim savings as per 9.5 or 9.6 as prescribed under section
   9.2.2.3 (f).
   - However, you could try using Exceptional Calculation Method.  In past,
   we were able to claim savings on industrial process compressor by
   submitting additional supporting documentation. Since ASHRAE 90.1 *doesn't
   regulate* such process loads, In that case Baseline has to
   be  developed carefully.  A narrative should describe all Baseline and
   Proposed case assumptions included for this measure as well as the
   calculation methodology used to determine the projected savings. The
   Baseline case description should verify that the efficiency measure is not
   standard practice for a similar newly constructed facility by providing a
   recently published document (*published within five years of the project
   registration date*), referencing a utility program that incentivizes the
   equipment installed, or by documenting systems used to perform the same
   function in other newly constructed facilities (*three* facilities built
   within the past five years of the project registration date). Savings
   associated with the proposed case measure should also be justified with
   published or monitored data. The possibility of acceptance is proportional
   to the robustness of the supporting documents and should be evaluated
   case-by-case which is also subjected to how far you convince the reviewer.
   - The above method was valid approach in v3 and most likely would be
   acceptable in V4 as well, I believe. However, it's worth submitting project
   specific CIR to get further clarity on this.

Hope this helps!
