<p class=MsoNormal><span lang=EN-GB style='font-size:11.0pt;color:#1F497D'>Just
to expand on Haider’s message, parametric analysis is applied to a base
building design to see the effect of changing (usually one or 2) design
parameters on a particular performance variable. The results are plotted as a
curve or a series of curves to illustrate the variation graphically. For
example, you might be interested to know the effect on building carbon
emissions of varying the amount of glazing in the building and you might want
to know this for 3 different types of glazing. The graph below was generated by
DesignBuilder using the EnergyPlus simulation engine by selecting the parameters
to vary. Because glazing provides both benefits (heat in winter and light) and
penalties (cooling load), parametric analysis can give useful insights into the
relationship between the design parameters and a chosen performance parameter
(annual carbon emissions in this case). In the example graph below there is a
minimum carbon emissions at just below 80% glazing and this might help guide an
architect at early stages of the design process towards a basic optimised
configuration.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-GB>Since you are posting to this group I am
going to give an example related to buildings. Let me start with modeling. You
can mathematically model the physic of heat transfer in a building. This
is <span class=apple-style-span>generally referred to as modeling.
The advantage of this is that you can simulate the heat transfer in the
building without actually have to build it or build a scale model. The inputs
of the building model such as window solar heat gain coefficient etc. can be varied within
some constraints to determine the disadvantage/advantage of that on the
building energy consumption thereby optimizing the building to consume the
least amount of energy. The varying of window solar heat coefficient in the
above example would be referred to as parametric analysis. This is a simplistic
yet time consuming methodology of optimizing the building energy efficiency
feature.</span><o:p></o:p></span></p>
