Hello everyone, 

It has come to my attention that there are documents related to Hot2000 energy modelling that I can not seem to locate. I'm hoping this forum topic will help. 

1. There is a bulletin out there pertaining to a workaround where Hot2000 can accurately model GHG. Specifically as it relates to the BC Step Code. (Something about pressing ctrl J when calculating?)

2. I've been looking for this document for some time: 

Guidelines for Using HOT2000 v.11 to Demonstrate Compliance with Subsection 9.36.5 of the 2015 National Building Code

Any help here would be appreciated! 

Many thanks, 

Colin Garratt

To get accurate GHG data from the file, you can also open the .h2k with notepad, you can then search for ghg and it will show the ERS and the update values. 

EnerGuide Rating System Workaround and Conversion Guide for HOT2000 v.11.11 Version 1  section 1.1.29

Hi Colin, 

If you use the method that I described above, you have access to all fields for the file including the reference house ghg numbers. Open the file with a notepad or word program to get the data (right click on the file in your folder and select 'open with') and you can use the search function to find what you are looking for. Feel free to connect with me if you need more help. Good luck!

Hi all, 

Thanks for the great info! This is very useful to have. I'll look into this. 

FYI: I've been looking at this since a client (gulp) told me about the keyboard shortcut.

There are source emissions factors provided by Energy Star Portfolio Manager. This would provide an accurate GHG value as well. Searchable online:

https://portfoliomanager.energystar.gov/pdf/reference/Emissions.pdf

Interestingly electrical GHG (g/kwh) for : Alberta = 690 and BC = 13 and Ontario = 30. So in terms of heat pump retrofits, not all regions will contribute to a reduction of GHG equally.

For EAs in the lower mainland:

The District of West Van has a memo where they use an emissions conversion factor for the GHG.

There is a separate calculator for the City of Vancouver where unregulated loads are accounted for (different from Step Code). 

So I'll follow suit here and follow the advice given here. Always good to have EAs on the same page. 

Thanks again for the help!

All the best,

Colin 

Thanks Mark and all, 

Follow up Q: If the BC Step Code is following the CoV GHG calcs, then will it similarly require accounting for non-typical loads? 

All the best, 

Colin
