Re: [EnergyPlus_Support] Different results from meter vs HTML- witch is correct?



Brent & Niraj, 

Thank you much- I ran this same model with annual building performance summery rather then Source Energy End Use Summery and found that you are correct I was mistakenly comparing source vs site energy, and the heating curve being close for site and source was due to the natural gas energy source. 

Again thanks for your response-

It varies by fuel type.  The default for electricity is 3.16, but the heating here is by natural gas which has a source multiplier of 1.084.

Brent,

 

Doesn't Source Energy and Site Energy differ from each other by a factor of about 3.1? If so, Jeremiah's heating energy seems fairly close together? Source and Site Energy, however, does seem to explain the trend in cooling and fan energy.

I think you are compare source energy to site energy.

Tell me it is not so- the meter file disagrees with the HTML file- and if this is so than who is correct- meter or HTML..? I have noticed this before- but now really need to get to the bottom of this- Possibly Linda or another will point out some very obvious thing I missed- 

I run the attached file- and get the attached results- then divide 1,000,000,000 J to get one GJ- then compare the results- way different . The same goes for kWh, but the J to GJ conversion is most simple-

 

Any insight as to why e+ would do such a thing would be very welcomed-
