T24 templates in Ladybug Tool

asked 4 years ago

I am thinking the best way to integrate 2019 California Title 24 templates (ENV, LPD, etc) into Ladybug Tool for early design stage. Is there a way that I can export all templates from somewhere and import them in Honeybee_Energy? Something like ASHRAE templates in honeybee_Energy?

I don't know of a way to import directly, but most of the space function assumptions in CBECC-Com are documented in ACM Appendix 5.4A (Space Use Data) and 5.4B (Schedules). Materials and envelope constructions are in 5.5, and performance curves are in 5.7. These appendices can all be downloaded in spreadsheet format here.

Those are useful information and I appreciate the 2019 schedule updates. Thanks Eric!

I'm not sure how important T24-2016 vs 2019 templates are to the OP.. What Eric linked to is the 2016 App5.4 docs.. It took us a while to find these for 2019 as they moved them into the software source code files. Here's where they are for me in Windows:

C:\Users\gcoll\Documents\CBECC-Com 2019.1.2 Data\Documents\RulesetSource\T24N\Rules\Tables

For space data: App5-4A_SpaceBySpace-T24N_2019.csv

I'm not sure where schedules are for 2019 but I'm sure you could use the 2016 schedules pretty safely for your purpose if you can't find them. Envelope constructions are in a few files there, but you might also check this previous post.

Good luck! Let us know if you build something cool.

Yes I linked the 2016 Appendices because I believe they are the latest set published online and the latest set published in XLS format. Also, I believe only 5.4A/B have changed since 2016; 5.5, and 5.7 have not changed since 2016.

I don't believe these are published anywhere, but here are the 2019 App 5.4B Schedules.

I can only imagine how hard to dig those files out of CBECC... Thanks Greg. We will se how it goes to implement t24 template into ladybug tool workflow.
