<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The image below (i.e. PSC report) shows the annual chiller load to be 2080.8 MBtu, or 173,400 ton-hrs (i.e. converted). The annual electricity usage is 145,469
kWh.<o:p></o:p></span></p>

<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Thank you for your sharing. I am doing a district chilled water project at present, your information is very useful.</span><br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I made the Baseline model with chillers and cooling towers as indicated in Apppendix G. The proposed model is modeled with one air-cooled chiller with average efficiency+piping loss.</span><br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">One thing I am not clear is what's the chiller curve like in your model? Because it is hard to set curves as a constant value. For example, a chiller's EIR curve should be a quadratic curve, how
do you make it into a constant value?</span><o:p></o:p></p>

<span style="font-family:"Times New Roman","serif"">Those are good questions.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">Answer to 1st question = yes</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">Answer to second is the following:</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">To be practical about this and simplify the modeling, we create a constant efficiency air cooled chiller to simulate the default DESv2.0 plant.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">The EIR is entered equal to 0.839 kw/ton, which equates to 4.4 COP + 5% losses.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">This represents the energy usage of the plant chillers, plant pumps, and cooling tower.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">We further create and apply performance curves that keep the EIR the same versus load and temperatures. In other words, Avg EIR = Max EIR = Min EIR = the EIR we enter into eQuest.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">It's easier to do this with an air cooled chiller because then you don't have to worry about a cooling tower and tower water pump in the model.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">This approach is simple and it works. I've used it on several LEED projects involving district chilled water systems.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">We probably give up some savings with this approach, but it's a lot of work to correctly model the actual performance of an actual CHW system in accordance with DESv2.0. If this isn't in our modeling scope
of work, we use the stipulated efficiency route.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">Hope this helps.</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">P.S. The stipulated efficiency approach does not work out well when modeling heating water and steam systems because the default efficiency numbers for those systems are pretty bad. That's not the case with
chilled water, at least if you are comparing to a Baseline based on air cooled equipment. If the building was big enough to require chilled water as a baseline, this approach will not work that well, and you would have to pivot to a new approach. Comparing
the stipulated efficiency against a App G Baseline water cooled chiller plant would probably result in little to no savings in the cooling equipment category.<br>
</span><br>
<span style="font-family:"Times New Roman","serif"">Thanks!</span><br>
<br>

<p class="MsoNormal" style="margin-left:.5in"><span style="font-family:"Times New Roman","serif"">Do you interpret the USGBC guidance for baseline district energy systems to be 4.4 COP + 5% losses averaged over the year? Meaning that the chiller in your model
should be modeled with a better EIR so that the average annual COP calculated using the PS-C report is 4.4?
</span><br>
<br>
<span style="font-family:"Times New Roman","serif"">Their use of the term "average efficiency" seems a bit vague.</span><br>

to be a quirk regarding a little shifting due to DST, but that’s a very small thing in the grand scheme of things. I want to say we tested it and the annual average value coming out of eQuest was ~ 99.3% of the average input value.

<p style="margin-left:1.0in"><span style="font-size:10.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Also, I don’t know if you are modeling the other buildings because a GBCI reviewer said you had to do that (assuming this is a LEED project) in order
to ensure that correct part load ratios on the chillers operating profile are appropriately accounted for. I got that sort of comment on a recent project and my response was something to the effect of … I could do that, but since we aren’t getting paid by
the owner to model buildings outside of the project scope just to make the chiller modeling more accurate, instead I will just use the default efficiency allowed by the DESv2.0 guidelines for water cooled chiller plants

<p style="margin-left:1.0in"><span style="font-size:10.0pt;font-family:"Calibri","sans-serif";color:#1F497D">That saved a lot of time with that change because if you do that, you don’t have to model any other buildings served by the system. If you are comparing
against air cooled equipment for the Baseline, you still get a decent amount of savings. I probably left some savings on the table because the plant had high efficiency VFD water cooled chillers, and VFDs on the pumps and cooling tower. I’m positive that
the annual efficiency was much better than 0.839 kW/ton, but (the way I look at this) we have to balance the level of effort on energy modeling versus the fees we are getting for the modeling.</span><o:p></o:p></p>

<p style="margin-left:1.0in"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">I am modelling a central cooling plant that serves many buildings on an college campus. For some buildings I am building the geometry and inputting internal gains.
For other buildings I have annual 8760 cooling load profiles. If I want to add these annual cooling load profiles to the CHW loop as process loads, would I have to make 365 day schedules (and 52 weeks)? If so I will write some sort of text generator out of
an excel file and paste in the .inp, but before I do want to see if there was any other way.</span><o:p></o:p></p>
