<br>
<br><font size="2" face="sans-serif">I have observed 3% difference in the
energy consumption for a given location while specifying two different
years (2010 and 2011). How does eQUEST (or any energy simulation s/w) internally
extrapolates the weather data based on the specified year?</font>
<br>
<br><font size="2" face="sans-serif">I feel 3% difference in energy is very
significant. Any guidelines on selection of TMY (typical meteorological
year) ?</font>
