[Equest-users] How to do LPD calculations in eQUEST

[Sharad Kumar via Equest-users]

Hi Rathna,

Could you please tell me the findings from the following equations.
The thing without doing it in eQUEST 3.65 is that
LOCAL("LIGHTING-KW")*1000/LOCAL("AREA")
may result in some other things as i know.

Actually i am unable to get the findings.
The things that i am able to interpret is that you will have the LPD (
watts per square feet) from this as per you.

Could you please tell me how without inputting kW one can get the
results anyhow. This seems to me to be me miscalculation and
mis-interpretation as per me as if you will input kW as power then there is
left no means to calculate the LPD as watts per square feet as this is not
within the limitations of eQUEST anyhow.


Thanks,

Hi Sharad,



Alternatively, once you enter the lighting power KW, you can just use the
user expression : LOCAL("LIGHTING-KW")*1000/LOCAL("AREA"), the LPD will get
updated by itself.

You can also use a BDL expression to do the same thing automatically and
eliminate a step. For example:



10*(#L("AREA"))



Where “10” is the wattage of the installed lights in the space and
“#L(“AREA”)” grabs the area of the space in which the lighting load is
being applied.



I hope this helps.



Sincerely,

incerely,

[Note about the above e-mail]:


Thanks Griffin, but the above message can help only when the lighting load
is 10 watts for one fixture but my post has been in general like  any
lighting power calculations can be done by my way.

Your way is to help with one lighting load but as per my e-mail the
lighting fixtures and their number can help to do the calculations.

Also one thing is missing that the window dialogue (as shown in
my snap-shots) has both lighting load as watts per square feet and kW which
can be input as one at one time.
