DOE Resources and Funding to Support Resilience Work

DOE Webinar: How Building Codes Facilitate Resilient Communities
September 21, 2023

Total System Performance Ratio (TSPR) is a metric for evaluating overall system efficiency instead of individual component efficiency, a solution that could also eventually facilitate the transition to a 100% performance-based code structure. TSPR is a ratio that compares the annual heating and cooling load of a building to the annual energy consumed by the building's HVAC system. This technical documentation provides background on the TSPR and support for the mechanical performance factors that are developed each 90.1 edition cycle to be used in the calculation. The current factors are developed for the 2022 edition of 90.1 in combination with addendum AG.

This document presents a methodology for assessing baseline energy efficiency in new single-family residential buildings and quantifying related savings potential.

Beginning in 2014, the U.S. Department Energy (DOE) funded a series of multi-year residential energy code field studies to explore energy savings opportunities from enhanced code compliance. This report presents the final results across the three phases to assess whether the education and training activities successfully improved code compliance to achieve significant changes in energy use.

The purpose of this report is to document findings and final results from the Texas field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Pennsylvania field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the North Carolina field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Maryland field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Kentucky field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Georgia field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

The purpose of this report is to document findings and final results from the Alabama field study, including a summary of key trends observed in the field, their impact on energy efficiency, and whether the selected education and training activities resulted in a measurable change in statewide energy use.

2022 NECC Presentation

This study investigates the technical feasibility of achieving zero energy (ZE) new residential and commercial buildings with national model energy codes. The approach and analysis are intended to provide guidance, inform goal setting, and direct future code development.

Summary of the full technical brief which provides requirements for electric readiness that could be incorporated into model residential energy codes. It provides background on the basis and benefits of the provisions, and model code language that can be plugged into the IECC or adapted into other energy codes.

Summary of the full technical brief which provides requirements for demand-responsive thermostats and water heaters that could be incorporated into model residential energy codes. It provides background on the benefits of these devices, impacts on the cost of construction, and model code language that can be plugged into the IECC or adapted into other energy codes.
