Revision history [back]

Sam, the NECB mandates the proposed model requirements for compliance analysis. As you are discovering, these requirements override the proposed design "baseline" model inputs in a number of areas. A few examples:

• The modeled shading coefficient is multiplies by 0.8 to account for incidental shading (dirt, etc.)
• infiltration is set to a constant value of 0.25L/s/m2 of gross wall and roof area.
• dwelling unit lighting power density is set at 5 W/m2.
• part load performance curves are set to those defined by the NECB.

There are other changes made to the proposed baseline that I am not recalling at the moment.
