[Equest-users] Space by Space LPD requirements for 90.1 modeling

Dear Javid,

 

You are right to question this review comment. Interior lighting is tradable
when using energy simulations not the prescriptive 90.1 requirements. I
suggest you send an inquiry to the review team requesting confirmation of
the requirement and further explanation. You should explain your
understanding of the Appendix G requirements and briefly explain how the
lighting is modeled in the baseline and proposed case. Clarifying the issue
before you make any changes to the model and resubmit could save a lot of
headache (and time). Good luck!

Subject: [Equest-users] Space by Space LPD requirements for 90.1 modeling

 

Dear All,

 

Recently i have received a comment from design team peer reviewer on
applicability of space by space lighting power density for 90.1 appendix G
compliance modeling for manufacturing facility and given as follows:

 

"Space by Space" method can only be used if the actual proposed design meets
the space by space requirements for each included space type.

 

I found similar discussion happened on 23/5/12- Building Area Method 90.1
(great insight from Nick) but didn't noticed any such requirements like
mentioned above. I am clueless on this and can't even verify if this is a
valid comment.

 

I would appreciate if someone could guide me on this.

 

Thanks in advance,
