It appears that these factors are meant to be multiplied by the total energy cost from each type of use. I see that at least in LEED Canada NC 1.0/1.1, the calculations for EQ p2 require 25% improvement in energy consumption (not cost) over MNECB. Presumably this requires use of the ESAF in that calculation. However, LEED also requires that calculations for energy savings are based on energy cost. When calculating energy costs, do you have to use the ESAF as well as the different utility rates? Or do you use the actual consumption (without using the ESAF) to figure the cost?<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>2.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>The code appears to require use of baseline systems that completely mirror the proposed systems – boiler for boiler, chiller for chiller, multi-zone for multi-zone. How have others found ways to show significant energy savings given this constraint? The newer versions of ASHRAE allow comparison of a proposed ground-source heat pump system, for example, against a boiler heating baseline system, or a VAV system against a packaged system, depending on various factors. But the MNECB and ASHRAE 90.1-1999 don’t allow this. I am struggling to see how it would be possible to get more than 20-30% savings given these rules. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-family:"Times New Roman","serif";color:#696EB4'>Anne Marie Moellenberndt </span></b><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'>PE LEED AP</span><b><span style='font-family:"Times New Roman","serif";color:#696EB4'><o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'>Senior Mechanical Engineer <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:12.0pt;font-family:"Times New Roman","serif";color:#595959'>Arup</span></b><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'>403 Columbia Street Suite 220 Seattle WA 98104 <o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'>t</span></b><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'> +1 206 749 9674 <b>d</b> +1 206 493 2244 <o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'>f</span></b><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'> +1 206 749 0665 <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif";color:#595959'><a href="http://www.arup.com/"><span style='color:blue'>www.arup.com</span></a><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div><font face="monospace">____________________________________________________________<br>
