This introductory course provides a practical overview of energy modeling and performance-based compliance under the 2025 New York State Energy Code. Participants will learn the basic concepts behind energy simulation, how modeling software and calculation engines are used, and where performance-based options fit within the overall compliance landscape. The course introduces the principal whole-building performance paths, including C407, ASHRAE 90.1 Section 12, and Appendix G, as well as the component- and system-level approaches in Appendix C, Appendix L, and C409 TSPR. It also addresses why a project may choose a performance-based approach, the role of mandatory requirements and performance backstops, documentation and software requirements, and the use of modeling for selected energy credits. Designed for participants with limited experience in performance-based compliance, the course emphasizes the purpose, structure, and practical application of each approach rather than detailed modeling procedures. It provides the foundation needed for more advanced 100- and 200-level training on specific performance methods and modeling requirements.

This training provides an overview of the ASHRAE Standard 90.1-2022 Energy Cost Budget Method as adopted by the 2025 New York State Energy Conservation Construction Code. The course explains the proposed and budget modeling framework and focuses on the requirements most likely to affect compliance results, including building envelope, HVAC, lighting, service water heating, renewable energy, and other regulated loads.

Key topics include thermal block development, budget HVAC system selection and sizing, ventilation and fan power, equipment efficiency, economizers, thermal bridging, lighting controls, purchased heating and cooling, energy credits, and the envelope backstop. The training also addresses application of the ECB Method to core and shell projects, tenant fit-outs, additions, and alterations, including how permit scope affects what may participate in the energy trade-off.

This training provides an overview of the ASHRAE Standard 90.1-2022 Performance Rating Method in Appendix G as adopted by the 2025 New York State Energy Conservation Construction Code. The course explains the proposed and baseline modeling framework, including use of the stable Appendix G baseline, and focuses on the requirements most likely to affect compliance results, including building envelope, HVAC, lighting, service water heating, and renewable energy. The course also explains the distinction between regulated and unregulated loads.

Key topics include thermal block development, baseline HVAC system selection and sizing, ventilation and fan power, equipment efficiency, thermal bridging, fenestration, infiltration and shading, lighting power and controls, service water heating, purchased heating and cooling, and requirements for plug, process, and other equipment loads. The training also covers the compliance calculations and allowed metrics for demonstrating compliance, including the New York State site-energy metric, and explains how prescriptive renewable energy requirements are incorporated into the performance calculation. The training also addresses application of Appendix G requirements to different project scopes where applicable.

This 2-hour training is designed for building officials, beyond-code program administrators, and others responsible for reviewing energy modeling submittals for performance-based compliance under the New York State Energy Code. It is also relevant to energy modelers seeking to strengthen internal quality control and better understand how performance-based submittals are reviewed.

The course introduces a practical, prioritized approach to reviewing performance-based projects. The primary focus is on the ASHRAE 90.1-2022 Section 12 and Appendix G compliance paths and how the Compliance Form, Performance-Based Compliance Review Manual, and New York State Companion Tool can be used together to support an efficient and consistent review process. The course also briefly addresses the NYSECC Section C407 Simulated Building Performance path, including required and recommended submittal documentation and a practical approach to reviewing C407 projects where equivalent standardized review tools are not available.

This 3-hour training will target building officials and beyond-code program staff tasked with the approval of performance-based submittals, as well as energy modelers for performing internal quality control to reduce the number of review iterations. It will focus on the plan review stage of the submittal review process, building on the material covered in 102 training. The training will develop skills to identify the impactful building systems and components to help prioritize the review effort and perform the essential review steps such as confirming that building systems and components shown in the Compliance Form reflect design documents; validating that the configuration of the baseline (budget) design model is established correctly based on the applicable rules of ASHRAE 90.1 Section 12 or Appendix G; establishing that, based on the simulation reports, the baseline (budget) and proposed designs were modeled as described in the Compliance Form; and that the compliance outcome was established correctly based on the energy modeling results.

This training explains how energy modeling can be integrated into the building design process to support design decisions and performance-based compliance with the 2025 New York State Energy Conservation Construction Code. The course uses the framework of ANSI/ASHRAE/IBPSA Standard 209-2024, Building Performance Simulation Process, to illustrate how energy modeling evolves from early conceptual design through construction documents and how modeling can inform decisions while design options are still flexible.

Key topics include establishing project performance goals, benchmarking, load reduction, HVAC system selection, design refinement, system integration and optimization, and evaluation of design alternatives. Examples illustrate how energy modeling can inform decisions related to the building envelope, ventilation, HVAC systems, lighting and internal loads, service water heating, and controls, including interactions among these systems and their effects on building performance and compliance.

The training also highlights 2025 New York State Energy Code provisions that can affect performance-based compliance outcomes, including envelope trade-off limitations, renewable energy requirements, ventilation and energy recovery requirements, electric-resistance heating limitations, thermal bridging, and the effect of energy source and the selected compliance metric. The course concludes with high-performance design case studies for multifamily, hotel, office, and school buildings, along with quizzes and examples that reinforce practical application of the design-process concepts.
