The Power of Parallel Compliance

Right now, you're basically flying blind. You pick a compliance path on day one, before you really know if it'll work, and cross your fingers. And when it doesn't work? You've just burned weeks. Your timeline's shot. Your budget's hurting. And you get to explain to the client why you need to start over. Sound familiar?

Here's what we built. You model your building once, and we automatically run both Section 11 and Appendix G at the same time. Not one after the other. Not as some manual backup plan. Actually simultaneously. So instead of: Pick one → Build model → Hope it works → Restart when it doesn't. You get: Build model → See both paths instantly → Pick the winner

Driven by EnergyPlus

No magic. No complexity. Just smart automation powered by the EnergyPlus.
‍
EnergyPlus is the gold standard for building energy simulation—used by engineers and architects worldwide, validated by decades of research, and trusted by code officials everywhere.
‍
We've built our parallel compliance workflows on top of this proven foundation. When you run both Section 11 and Appendix G simultaneously, you're getting the same rigorous, accurate simulations you'd get if you ran them separately. Just faster and smarter.
‍
How It Actually Works

✅ You build your model (same as always, no new learning curve)
‍
✅ We generate both baselines automatically (Section 11 Budget Building and Appendix G Baseline, following all the rules)
‍
✅ EnergyPlus runs both simulations together (parallel processing, not sequential)
‍
✅ You get one dashboard showing both paths (clear, comparable results)
‍
✅  Need to adjust for local codes? Override.

Launching on the 12th of January

We're putting the finishing touches on something we think is going to change how you approach ASHRAE 90.1 compliance.What's Coming On January 12th, Better Building launches full support for ASHRAE 90.1-2019 Section 11 and Appendix G parallel compliance workflows. This isn't a beta. This isn't a preview. This is production-ready, tested, and ready to use on your next project. What You'll Get on Day One:

✅ Full Section 11 Performance Cost Index (PCI) method
✅ Complete Appendix G Performance Rating Method (PRM)
✅ Simultaneous parallel processing
✅ Automated baseline generation for both paths
✅ Real-time compliance feedback
✅ Flexible overrides for jurisdictional requirements
✅ Comprehensive documentation for both methods
