color:#1F497D'>To add to the discussion on a stepped back and more general
level – the phrase “baseline model” doesn’t mean
anything specifically by itself. The decision of whether you’re
supposed to use 90.1 to your define your baseline (or some other baseline standard
criteria, or the existing building, and/or your own sole judgement) is
determined by the nature of the project and why you’re performing energy modeling
in the first place.<o:p></o:p></span></p>

color:#1F497D'>Pre-made baselines, in the context of 90.1, do not exist as they’re
unique to every proposed design. If you’re looking for a
predetermined baseline performance based on energy consumption, you might
consider using a tool like Energy Star or similar resources that offer “average”
EUI figures for various building types/sizes/locations.<o:p></o:p></span></p>

<div>
<p class=MsoNormal>There are a couple of ways to do what you are asking. <o:p></o:p></p>
</div>
<ul type=disc>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'>Start by creating your proposed building design
with all of the ECM features and proposed HVAC systems<o:p></o:p></li>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'>For most of your ECM's that are straight forward
you can use parametric runs under the TOOLS menu in DDedit mode to
'back-out' the proposed performance down to the baseline performance
values. Basic things would include changing insulation values,
changing glass u-values, overhangs, LPD values, equipment efficiencies,
etc. The results of your complied parametric runs will represent
your baseline building performance results.<o:p></o:p></li>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'>OR (I use this method when my proposed HVAC
systems are different from the required baseline HVAC systems.)
After you have created your proposed model and have it calibrated to debug
it and reduce your throttling hours out of range to acceptable levels then
do a "Save As" of your proposed file to create an identical file
that you will adjust to represent your baseline performance values.
Using this method allows you to re-input the baseline HVAC systems in the
main eQuest systems & plant screens rather than trying to change your
systems via the parametric runs tool. I then go back and reinput all
of the other design characteristics to match my baseline values that I am
using.<o:p></o:p></li>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'>Now I have two separate files for the baseline
& proposed cases, but I am assured the initial inputs of the building
(area, shape, window placement, etc.) are identical for both building
models. The only variances are the ones I have made to represent
thermal performance values.<o:p></o:p></li>
<li class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;
mso-list:l0 level1 lfo1'>By reducing the performance values in your
basline model you will see the annual energy consumption increase above
the proposed model results provided that your simulation is working
correctly.<o:p></o:p></li>

<p class=MsoNormal>Hi all,<br>
<br>
1) I need to make my proposed model use energy less than
300kWh/m2/yr, and <br>
2) I have to indicate how much energy the proposed model can save compared to a
baseline model.<br>
<br>
I am not sure how to build a baseline model.<br>
To create a baseline model, do I have to follow all the materials on
ASHRAE 90.1 and change all the setting on eQUEST SD wizard while keeping energy
consumption of 300kWh?<br>
Or is there a baseline already made?<br>
<br>
Does anyone know how to do the above while satisfying 1) and 2)?<br>
<br>
Thank you for help.<o:p></o:p></p>
