Use the model while the design can still change.
Energy modeling is most valuable before the project is locked. We test envelope assemblies, glazing, shading, ventilation, peak loads, and mechanical assumptions early enough to guide the design instead of documenting it after the fact.
Design analysis, certification, code, and incentives all need different answers.
Options before commitments
Compare assemblies, window packages, shading, airtightness targets, and HVAC options against annual demand and peak load.
PHPP and WUFI-Passive
Carry design assumptions into a certifiable model and keep the documentation trail aligned with PHI or Phius expectations.
Code and incentive pathways
For commercial or mixed-use projects, baseline/proposed models and incentive coordination may require a separate Appendix G workflow.
A model should produce decisions, not just compliance.
Useful output includes annual heating and cooling demand, peak loads, envelope performance by assembly, thermal-bridge impact, ventilation assumptions, mechanical sizing implications, and the next design moves needed to hit the target.
