<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. </FONT></DIV>

<DIV><BR></DIV>
<DIV class=WordSection1>
<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?<o:p></o:p></P>
