So the LEED interpretations say that both baseline and proposed should use the same fuel with the same rate structure, whether it is oil, gas, coal or biomass. However, depending on the type and source of the biomass fuel, it may be considered "renewable" for LEED. If it qualifies as a renewable energy source, the energy cost becomes zero in the proposed case, and significant savings might be realized under EAc1. </div><div><br></div><div>Check the LEED reference guide for the types of biomass that qualify as renewable. Generally speaking it has to be agricultural waste, and must be locally sourced. </div><div><br></div><div><div>--</div><div><br></div><div>Chris Schaffner, PE</div><div>LEED Fellow</div><div>Founder and Principal</div><div><br></div><div>The Green Engineer, LLP</div><div>Sustainable Design Consulting</div><div>50 Beharrell Street</div><div>Concord, MA 01742</div><div>T: 978.369.8978</div><div>M:978.844.1464</div><div>chris@greenengineer.com</div><div>www.greenengineer.com</div><div><br></div><div>The Green Engineer, LLP is a Certified B Corporation</div></div><div><br></div><div><br></div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Verdana; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> Javier Duran <<a href="mailto:javier@b-green.cl">javier@b-green.cl</a>><br><span style="font-weight:bold">Date: </span> Wed, 12 Oct 2011 18:44:57 -0300<br><span style="font-weight:bold">To: </span> Nick Caton <<a href="mailto:ncaton@smithboucher.com">ncaton@smithboucher.com</a>><br><span style="font-weight:bold">Cc: </span> <<a href="mailto:bldg-sim@lists.onebuilding.org">bldg-sim@lists.onebuilding.org</a>><br><span style="font-weight:bold">Subject: </span> Re: [Bldg-sim] LEED Baseline system definition<br></div><div><br></div>Hi everyone<div><br></div><div>During last week greenbuild at toronto i met a reviewer i and ask her what kind of baseline system should i have when using biomass as heating fuel in the proposed system. </div><div>She give me a different 'view': i should consider using biomass in both buildings, so i could only take advantage of the energy efficiency of the bioler (furnace) in the proposed, then i should consider the most used system's efficiency in the zone.</div><div>what do you think?, still confusing for me!</div><div><br></div><div><br></div><div>-- <br>Javier Durán Palma<div>Gerente General B-green SA</div></div><div><br></div><div><br></div><div><br></div><div><br><br><div class="gmail_quote">

Perhaps circumstances specific to the region of Chile you’re working in mean an equivalent electric heating source would be infeasible?
