Hi All,<br><br>I'm completing a model of a building that is heated by a central campus steam plant for LEED NC 2.2 EA P1 and C1. I've followed the guidelines in "Required Treatment of District Thermal Energy in LEED NC 2.2 and LEED for Schools" dated May 28, 2008.<br>
<br>I'm doing pretty well, but I'm a bit confused by the following paragraph (page 8 under the heading: Energy Model Implementation – Energy rates)<br><br>Step 2 (Aggregate Building / DES scenario) – in this modeling scenario the DES-supplied energy is not<br>
modeled as cost-neutral purchased energy, and thus purchased DES rates (chilled water, steam, hot<br>water) are ignored. Fuel and electricity rates are assigned using the local utility rate schedules as they<br>would normally apply to the building and using the normal ASHRAE and LEED modeling rules. For<br>
the Baseline Building the rates are applied to the code-compliant heating or cooling plant as instructed<br>in Appendix G, and for the Proposed Building the rates are applied to the virtual plant according to the<br>actual energy sources used in the upstream DES (electricity, gas, oil, etc.).<br>
<br>They are a bit unclear...<br><br>If the central plant burns #6 oil, do you use the local rate for #6 oil for the proposed system and the local rate for home heating oil for the baseline?<br><br>OR<br><br>do you use the local rate for home heating oil for both?<br>
<br>Has anyone submitted one of these projects yet?<br><br>Thanks for your help.<br><br>--<br>Karen<br>
