Nebraska’s New Residential Energy Code Requirements and Best Practices

2 Oct 2024

Building Envelope Code Requirements General Requirements Section C402.1 Building thermal envelope to comply with the following: • Specific insulation requirements of Section C402.2 • Thermal requirements of either: • R-value-based method of Section C402.1.3 • U-, C-, and F-factor-based method of Section C402.1.4 OR • Component performance alternative of Section C402.1.5 • Fenestration in building. [...] Dept of Energy requirements Additional Efficiency Package Options Section C406 • Buildings shall comply with one or more of the following: • More efficient HVAC performance • Reduced lighting power • Enhanced lighting controls • On-site renewable energy • Dedicated outdoor air system • High efficiency water heating • Enhanced envelope performance • Reduced air infiltration Additional Efficiency Pa. [...] Dept of Energy Occupant Sensor Controls Sections C405.2.1, C405.2.1.1 • Occupancy sensors are required in many spaces, including: • Classrooms • Conference/multipurpose rooms • Lounges/breakrooms • Enclosed offices • Open plan office areas • Restrooms • Storage rooms • Warehouse storage areas • Occupancy sensor function (other than for warehouses): • Automatically turn lights off within 20 minutes. [...] • Many more stakeholders than IECC Development • Glide slope to Net Zero by 2030 • Expanded Appendices • Carbon Impact/Credits 2024 National Energy Standard (Cont.) • More focus on Electrification • Tables for Envelope and Fenestrations (402/403)updated • More reliance of high performance • More focus on testing/verification • More intent to move appendices items forward in 2027 & 2030 versions 20. [...] 90.4 -Small Computer rooms still under 90.1 Key Takeaways • 2024 Energy Standard has new requirements for: • Electrification • EV Charging • Solar • Grid Interaction • Carbon • Using & Understanding Guides and formulas is critical • Good Design!!! • Proper envelope construction is key • Right-sizing HVAC is required • Documenting construction and certification 77 Resources • DOE 2018 IECC Presenta.
