Residential basement insulation levels should be selected in accordance with the International Energy Conservation Code, or the local energy code. Be sure to insulate both the masonry and stud walls of daylight basements.

Pacific Northwest National Laboratory analyzed the relationship between the Residential Energy Services Network (RESNET) Home Energy Rating System (HERS) Index and the traditional simulation-based Performance Path used in the International Energy Conservation Code (IECC). The analysis evaluates, for a single-family residence with various characteristics, the ranges of HERS Index values that would imply compliance with the 2012 IECC Performance Path. Several building characteristics considered likely to result in quantifiable differences in the outcomes of the two approaches, or otherwise believed to be of interest to code developers and policy makers, are considered in the analysis.
This document lays out the U.S. Department of Energy’s (DOE’s) methodology for evaluating the cost-effectiveness of energy code and standard proposals and editions. The evaluation is applied to new provisions or editions of ANSI/ASHRAE/IES Standard 90.1 and the International Energy Conservation Code. The methodology follows standard life-cycle cost (LCC) economic analysis procedures. Cost-effectiveness evaluation requires three steps: 1) evaluating the energy and energy cost savings of code changes, 2) evaluating the incremental and replacement costs related to the changes, and 3) determining the cost-effectiveness of energy code changes based on those costs and savings over time.

The Building Codes Division, part of the Department of Consumer and Business Services, enforces the building code to protect the public and prevent unsafe construction work. Oregon has one statewide building code providing a uniform, consistent and predictable process for Oregon’s construction industry, the public, and state and local government.
Oregon’s building code is applicable in all cities and counties and is enforced locally across the state. The Division provides code enforcement in areas of the state where the local jurisdiction does not.
This document contains sample survey questions designed for use by states wishing to conduct a survey of their building jurisdictions as one method of better understanding energy code compliance rates in their state.
