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

[Rathna Shree via Equest-users]

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.

 Dear equest users,
Today morning after doing the LPD calculation in excel i discovered something that is LPD calculation in eQUEST 3.65 which can be new for few or many people.
This can be implemented when one know the Lighting power of the fixture and number of fixtures.
There is a very innocent way to do it that is we can multiply the number of fixtures and lighting power in calculator and then input the lighting load in kW in the internal load where there is space for lighting power.
Then we can come up with the lighting power density in the corner space of the same window.
After this one can remove the lighting loads in kW and put in watts per square feet that is the lighting power density.
I will have the snapshot of the same dialogue.





We can come up with the above snapshot that the 0.012 kW results in 0.044 watts per square feet of LPD which can be treated as LPD calculation by me. The actual area in the model calculates it.

Thanks,Sharad.Kumar|Engineer.Green Horizon Consulting LLP.Gurgaon.India.
