<div><font face="Calibri">For building energy simulation programs validation protocols are like professional registration exams, you can only do a limited number of previously addressed/"solved" specific problems to "prove" competency to qualify to practice
(and then subsequently step off the "academic" platform and into the larger world -- and do your best). Having said that, we are striving to take validation as far as we can.</font></div>
<div><font face="Calibri"></font> </div>
<div><font face="Calibri">I recommend the following as a starting point for studying validation methodology; and you can search on the authors at the "NREL publications data base" for more recent material.

<p class="MsoNormal">Hi,<br>
<br>
This requires input from masters of energy modelling, so plz give suggestions!<br>
<br>
I have modelled a test chamber with radiant floor cooling system + OA ventilation using EnergyPlus. The model has been prepared as per the specification of a published paper of a renowned Journal. The experimental data of the test chamber as given in the paper
has been matched with my energyplus results. So, here are my queries:<br>
<br>
1. Will this be considered as validation of the methodology used in the software and now I can make changes in not only the HVAC system but also in the building envelope as well. My concern is that, by changing the building envelope and HVAC system do the results
of my model be considered as validated or not. Can anyone share the model result validation protocol.
<br>
<br>
2. If I put DOAS in the same model with same envelope details and compare it with other cooling systems for a particular climate does the model results be considered as validated or not. In other words, can I make changes in the HVAC system keeping envelope,
schedules and other loads similar to the original data and consider my model results to be validated or not.<br>
<br>
In many cases what I have seen is that the models are validated using experimental data but what if there is no experimental setup available, then will this approach of using a published data from previous experiment to validate your own modelling approach
and then making desired parametric changes to find results suffice or not?</p>
