[Bldg-sim] LEED Canada CS - What to use for Plug Load Density

[韩星]

Hi Aaron,


Is it LEED project? If so, in my opinion, if the process energy accounts for no less than 25% of the total energy consumption, it will be OK.
I used 13W/m2 and 15W/m2 before, both OK to acquire the certificate, and I even do not need to explain how the 13 or 15 W/m2 comes.
The elevator energy is included in the process load, so you do not need to separate it out.

Hi,

 

It is unclear to me how to model plug and process loads for Core and Shell Projects in Canada.  There seems to be a conflict between Appendix 2 and the Table on Page 292 of the Reference Guide.  Has anyone else run into this before we send in a CIR?

 

The Appendix wants you to use Table 1 plug load densities (i.e. 1.5W/sq ft for office buildings) for the tenant spaces while Page 292 says to use values from the standards (i.e. 0.75W/sq ft for office buildings) or provide documentation for modelled loads. 

 

It’s almost like they want you to use the higher value for tenant spaces to account for unknown plug and process loads in CS projects (server rooms and resultant A/C, etc.).  If so, I’m not sure if we should still model elevators, escalators in the common areas or if they are supposed to be accounted for Table 1.

 

Any thoughts are appreciated!


Aaron
