<DIV dir=ltr align=left><SPAN class=180112215-16032010><FONT color=#0000ff
size=2 face=Arial>Depending on the type of building it is very difficult to
get an accurate match between the predicted and actual energy usage.
There are a range of reasons why this can be the case.</FONT></SPAN></DIV>
<UL dir=ltr>
<LI>
<DIV align=left><SPAN class=180112215-16032010><FONT color=#0000ff size=2
face=Arial>Weather. How does the weather file used relate to the weather from
the measured period? If it was hotter or colder, this will have implications
for the comparison between the two figures.</FONT></SPAN></DIV></LI>
<LI>
<DIV align=left><SPAN class=180112215-16032010><FONT color=#0000ff size=2
face=Arial>Usage. All building simulation tools assume a set period of
occupancy and resultant heat gain - unless you know the occupancy and
equipment usage patterns for each hour of the year, there will be differences
between the two figures. Are there any data centres (and resultant high power
consumption) that have been implemented in the building but aren't on
drawings?</FONT></SPAN></DIV></LI>
<LI>
<DIV align=left><SPAN class=180112215-16032010><FONT color=#0000ff size=2
face=Arial>Operation. Perhaps the biggest cause of potential discrepancy. Is
the actual building being operated in exactly the same way as input to the
software? Commissioning and operation are perhaps the most important things to
get right if buildings are going to produce the kind of energy savings that us
engineers are predicting.</FONT></SPAN></DIV></LI>
<LI>
<DIV align=left><SPAN class=180112215-16032010><FONT color=#0000ff size=2
face=Arial>Sub metering. Has the building been submetered in any way to allow
you to identify where the discrepancies lie? From the graph it looks like
there is additional consumption during warmer months that isn't being picked
up to the same extent by the simulation. </FONT></SPAN></DIV></LI></UL>
