General Information
Quick Description
The Non-Residential Energy Code allows a person applying for a permit to use one of three different methods to demonstrate compliance with code requirements. A local building jurisdiction will require that Non-Residential Code Compliance Forms are submitted with a building permit application. The Non-Residential Code Compliance Forms can be downloaded through this Web site or are available through local building jurisdictions.
Prescriptive Compliance Path
The Prescriptive Compliance Path is the most commonly used method to demonstrate compliance with code. The prescriptive path is simple and easy to follow for almost all building construction types. It is recommended that all buildings attempt to use the Prescriptive Compliance Path to demonstrate compliance. The Non-Residential Code Compliance Forms have copy-ready forms and instructions necessary for following the Prescriptive Compliance Path.
Simplified Trade-Off Approach
The Simplified Trade-Off Approach (STA) allows the applicant to trade-off building envelope components. It may be necessary to use STA if a building exceeds prescriptive window-to-exterior wall area allowance or if reduced insulation levels are desired for any of the building envelope components. STA requires the use of CodeComp software package, which does an annual heating and cooling load calculation of a building and compares this to an equivalent building that complies with Prescriptive Compliance Path.
- Whole Building Approach
The Whole Building Approach (WBA) is the most difficult and least used path to demonstrate compliance with energy code. The WBA allows trade-off between all code-regulated elements that affect energy use (envelope, lighting, HVAC). It requires use of USDOE 2.1E building simulation program and strict adherence to minimum specifications as specified in Methodology for Compliance using the Whole Building Approach.
1996 Code Updates
Background
In 1994, the Energy Committee of the Oregon Structural Code Advisory Board began review and development of non-residential energy code standards. The code was modified through a public process, primarily through the Energy Committee. Code requirements were based on prescriptive requirements rather than performance requirements. As a result, the code is now simpler and easier for code jurisdictions and permit applicants to demonstrate compliance.
- General Changes
The updated energy code requirements were released in 1996 along with support documents and software developed by this office in support of code. The Oregon Structural Specialty Code underwent major formatting changes in 1996 that aligned with changes to the Uniform Building Code. The energy code requirements can be found in Chapter 13 of the Oregon's amended code. Forms and support documents were also updated at that time. For the most current versions of software and manuals consult the Publications & Software section of this Web site.
