Clean �ur.reo ��ur sl,lle:� <br />In addition to the contractual M&V plan for this ECM of verifying boiler efficiency, Ameresco analyzed data <br />from the building automation system to confirm that the hot water reset schedule is operating as expected. <br />The anticipated hot water reset schedule was for 100-degree hot water when the outside air temperature is <br />65 degrees and 140-degree hot water when the outside air temperature is 30 degrees. The chart below shows <br />that the reset schedule is operating correctly, with approximately 100-degree hot water being supplied when <br />the outside air temperate is 65 degrees and approximately 130-degree hot water being supplied when the <br />outside air temperature is 30 degrees. Since the hot water supply temperature is 10 degrees less than <br />anticipated when the outside air temperature is 30 degrees, additional savings are likely being realized from <br />the hot water reset schedule. <br />135 <br />Government Center Hot Water Reset <br />
