[Bldg-sim] RMESE Meeting January 22

I have a lot of experience with incentive 
programs and modelling to energy codes or 
standards that do not include any inclusion of 
economics - ie. how to define utility rates how 
to avoid fuel switching between proposed and 
Baseline cases when the Baselines systems can 
look significantly different than the proposed 
case systems.  Not particularly by choice but more by age.

The Canadian Federal government instituted 
incentives for showing energy savings over first 
the ASHRAE 90.1-1989 Baseline.  The C2000 program 
defined how the energy savings were turned into 
cost savings incentives  - I can remember any 
modifications to 90.1 but the way energy 
efficiency measures were implemented and modelled 
or post simulation adjusted.

This effort somehow morphed in the Green Building 
Challenge of which the energy model was a very 
small component of the overall rating.  Again, I 
don't recall any specific modifications to the 
90.1 Baseline case but how the proposed was 
modelled and how savings were calculated was defined for that program.

Then the MNECB came out with a whole building 
performance path.  This was very loosely defined 
and the first step was to define the modelling 
software requirements, then how the Proposed and 
Reference cases were to be modelled.  The first 
incentive programs were based on fairly strict 
requirements and a "help" system was published to 
assist users with the model requirements without 
defining any keywords, explicit software 
etc.  DOE2.1d/e was available at the time - no 
interface at all.  Text editor and debug.

The review process was quite 
interesting.  Somehow I had ended up modelling 
the first LEED Gold project awarded by the USGBC 
in Canada.  This qualified me to review MNECB 
incentive models - Proposed and Reference case 
soft ware supplement and the help system.

My main point is that incentives typically 
regionally based.  The state, or other authority 
has to base the incentive program on local, 
typical "baseline" construction and 
economics.  Appendix G doesn't necessarily have 
to be revised to take into account these regional 
requirements.  I think it would be very difficult 
do modify A global standard to include some 
accounting of regional requirements for developing local incentive programs.
