I don't think arbitrarily adding process energy to your building is what LEED is looking for. Is this what your reviewer specifically asked you to do?</div><div><br></div><div>Cheers,</div><div>Dan</div><div><br><div apple-content-edited="true">

Our HVAC system is a geothermal water-to-air heat pump system with an electric back up boiler. There will be no gas usage. For this scenario, system type 4 was used for the baseline case. Since a majority of the winter will be spent below the heat pump operating temperature, in heating mode, electric resistance is the main source of heating. This being said, my baseline system has a very large annual heating consumption.<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: 'Optima LT'; "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: 'Optima LT'; ">Now to my dilemma. With the large heating consumption in the baseline design, the process load was below the 25% threshold. I was advised to increase the plug load until I was able to surpass the 25%. After multiple iterations, I came to a value of 3.7 W/sqft for the office spaces (the building is primarily offices). Obviously this is much greater than anticipated for offices spaces.<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: 'Optima LT'; "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="font-family: 'Optima LT'; ">Initially the process load was 30% with my<span class="Apple-converted-space"> </span><u>proposed design</u>, but after the modifications the process load was roughly 50% of my total energy consumption.
