<span style="FONT-SIZE: 10pt; FONT-FAMILY: "Times New Roman","serif"">The objective of this research is to develop a new method to determine the shortest time period for energy use monitoring involving hourly (or sub-hourly) data that will yield reliable and
accurate long term energy use estimates within acceptable uncertainty limits. By evaluating the uncertainty in the measured data as the monitoring period progresses, the new method will allow users to evaluate the energy performance and calculate energy savings
in commercial and institutional buildings, in a cost-effective short-term monitoring period instead of the current year-long monitoring stipulated in most M&V protocols. The new approach would resolve the problem of needing long-term monitored data, which
is often very costly to obtain and/or historically unavailable. In addition, this measurement/extrapolation approach should be designed as simply as possible to meet the uncertainty targets in energy savings stipulated in M&V protocols such as ASHRAE Guideline

<div>Dear all,<br>
<br>
I have monthly gas data for a soccer stadium and I'm trying to develop it toward daily (or even hourly) data so this can be used in subsequent assessments.<br>
<br>
My own efforts on previous assessments have extended to relatively crude application of multipliers (possibly based on a simulation study) and an overall divisor. This is very limited, especially in this case.<br>
<br>
In an ideal world, it would be helpful to develop the daily consumption weighted with the following factors:<br>
<ul>
<li>Parasitic losses - these can be estimated from when the facility is largely closed during the off season
</li><li>Historic game fixtures - readily available from the web </li><li>Weather, including about 1MW of underpitch heating </li></ul>
<p>I'm surrendered to the possibility that this is well beyond me! But, can anybody suggest excel functions or other software tools they may have used, or even what math for me to look up on Google?
<br>
</p>
<p>Many thanks <br>
</p>
<p>Chris<br>
