The International Energy Conservation Code (IECC) prototype building models (prototype models) were developed by Pacific Northwest National Laboratory (PNNL), in support of DOE's Building Energy Codes Program (BECP), to simulate energy savings associated with changes in energy codes and standards. For residential buildings, PNNL utilized two base prototypes to simulate both Single-family detached house, and Multi-family low-rise apartment building types. Energy models for the recent versions of the IECC are available for each climate.

Summary of the findings of the 2003 Residential New Construction Baseline Study conducted by Itron, Inc. under Pacific Gas & Electric (PG&E) management.1 KEMA-Xenergy conducted the on-site surveys. The RNC baseline study investigates energy efficiency in newly constructed single family homes throughout California. The study’s primary purpose is to provide information to residential new construction (RNC) program managers across the state, thereby allowing them to assess and address the effect of recent energy code changes on these programs.

This document contains checklists of items to photograph while onsite to help answer questions that may arise regarding the accuracy of entries in the data collection form. Questions may be raised during quality assurance reviews by the project team and PNNL. For each piece of data entered, it is a best practice to have photo-documentation to facilitate future validation of that value. Photographs are also extremely useful for subsequent training programs, field guides, and educational documents.

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.

This document is an update to the Department of Energy’s (DOE) cost-effectiveness methodology originally published in August 2015. Changes include correction of a typographical error in lifecycle costing equations and building prototype enhancements; updating the weighting factors for foundation types and system types based on permit data from the U.S. Census and current housing starts data from the U.S. Census and Residential Energy Consumption Survey (RECS), updated representative climate locations for both national and state level aggregations, adding a section on data for measure lifetimes, and the addition of the determination strategy for compiling first costs of measures and economic parameters.

In early 2017, the Nebraska Energy Office expressed interest in evaluating the construction of new single-family homes in Nebraska using the US Department of Energy’s (DOE) low-rise residential evaluation methodology.1 As part of that methodology, Pacific Northwest National Laboratory (PNNL) was directed by DOE to analyze the data collected in Nebraska. This memorandum provides and discusses the results of PNNL’s analysis.

The objective of this report is to assess the compliance of newly-constructed single-family homes with the Vermont Residential Building Energy Standards (RBES). This analysis is part of a broader study of the single-family residential new construction market in Vermont.

Final report of the U.S. DOE Multifamily Residential Energy Efficiency Field Study to validate the impact of building energy codes in low-rise multifamily buildings and identify opportunities for increased energy that can be addressed through workforce education & training programs. Results include both characteristics summaries (by state) and an analysis of the opportunities associated with increased code compliance on building energy use in the different climate zones. As well, the process of collecting and processing building data so that these estimates can be prepared is described in detail, with the intent that others could employ this process in future studies. This report also includes a market research component that describes interviews with key actors in the multifamily sector (building designers, developers, and builders) that focuses on various aspects of the code, including specific code details relevant to code education and training, and overall energy performance.

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