[Bldg-sim] [Equest-users] Modelling comparison to the new OBC SB-10

[Chris Jones]

OBC SB-10 offers three paths for compliance (see Division 3, 1.1.2.1.(1):

(a) - MNECB performance path - show more than 25% 
savings over the MNECB, no changes to the EE4 
generated model required.  Note, there are no 
modifications to the MNECB required.

(b) - exceed ASHRAE 90.1-2010 by 5%.  This is the 
performance path, following 90.1-2010, Section 11 
with the modifications specified in Chapter 2 of SB-10.

(c) - meet the ASHRAE 90.1-2010 prescriptive path 
(with SB-10 Chapter 2 modifications).

If following the ASHRAE path make sure the 
project meets the mandatory requirements.  For 
example, Section 9.4, Lighting controls - all 
kinds of occupancy sensors required where the 
would not be if following the MNECB path.

If you are following the MNECB path, make it 
quick.  The Ministry is working to get software 
for following the ASHRAE envelope trade off 
method.   As well, canQuest is due out any day 
now and once it has been beta tested and 
approved, the MNECB and EE4 will be dropped from the OBC.
