<div>There are a couple of ways to do what you are asking. </div>
<ul>
<li>Start by creating your proposed building design with all of the ECM features and proposed HVAC systems</li>
<li>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.</li>
<li>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.</li>
<li>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.</li>
<li>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.</li></ul>

<div>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.<br>
