involved using custom efficiency curves (which I am not). The issue is - I’m getting negative cooling energy, particularly during the shoulder economizer months. I either need help identifying this novel energy source so I can patent it and become filthy rich,
or figure out how I broke DOE2…</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif""><o:p></o:p></span></p>
