<p class="MsoNormal"><span style="COLOR: #1f497d; FONT-SIZE: 11pt">For the tenant spaces with a lease agreement for the lighting power densities, I would use assumptions for space breakdowns, and then apply the lease agreement lighting power density reductions. I also suggest listing these assumptions in the modeling report (or narrative). To get an assumption of an office area breakdown, one way could be to build a quick eQUEST model of the office floor space, selecting “building type” as office in the wizard, then going into the detailed wizard to find the default space area breakdowns (80% office space, 5% washroom, 5% kitchen, etc). I am not sure what the eQUEST default area breakdowns are based on, but that info may be available somewhere in the eQUEST documentation. <u></u><u></u></span></p>

<p class="MsoNormal"><span style="FONT-SIZE: 10pt">Hi,<u></u><u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE: 10pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE: 10pt">I’m preparing a model for an office building for LEED Canada CS 2009. Modelling is with EE4 following NRCan rules with an MNECB reference building. Base building includes rooftop units, baseboard perimeter heat, core area with washrooms, electrical rooms, stairwells, elevators, etc. One floor of the building has a ceiling in place with VAV boxes, diffusers and lights laid out for an open office plan (as laid out in the lease). The other two floors of the building have VAV boxes installed as base building but the tenants will be responsible for installing lights or diffusers in tenant fit-ups. Walls will probably be added and VAV boxes may need to change at that point in time.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE: 10pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE: 10pt">I had the owner put requirements in the lease for lighting power density and lighting controls (Core Performance Guide) so I’ll be claiming credit for those. The problem I have is that there are no floor layouts indicating open office areas, private offices, conference rooms, staff rooms, etc. so I’m not sure what to use for reference building lighting power density and plug loads in the leased tenant areas. My first thought for lighting was to use the building area method for the reference building then use a mix of actual installed lighting and Core Performance Guide lighting densities in the proposed assuming all open office plans for the tenant fit-up areas. Any comments would be appreciated. <u></u><u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE: 10pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE: 10pt">As a side note, I don’t see any requirement in Canada for 25% of energy being process like there is in the US.<u></u><u></u></span></p>
