ASHRAE 90.1 Performance Modelling

ASHRAE 90.1 Compliance Modeling for LEED, NYC Energy Code & Commercial Buildings

Performance-based ASHRAE 90.1 energy modeling that proves code compliance, secures LEED energy points, and satisfies AHJ plan reviews for commercial and institutional buildings across the U.S., Canada, and international markets. Using EnergyPlus and DesignBuilder, we build accurate baseline and proposed models that quantify energy cost savings and support your sustainability goals.

We deliver performance-based ASHRAE 90.1 energy modeling that demonstrates energy code compliance for commercial and institutional buildings across the United States, Canada, and international markets. Our models are developed using the ASHRAE 90.1 Appendix G Performance Rating Method, supporting building permits, authority-having-jurisdiction (AHJ) reviews, LEED certification, and utility incentive programs.

By developing accurate baseline and proposed building models, we quantify percentage energy cost savings and ensure alignment with jurisdiction-specific code adoption, including the NYC Energy Conservation Code (NYCECC). Our approach emphasizes transparency, technical accuracy, and reviewer-ready documentation that passes review the first time.
