Heads up: There are no amended sections in this chapter.
The 2019 Oregon Zero Energy Ready Commercial Code, Part I, commercial energy provisions, consists of the following:

  • Chapter 1 of the Oregon Structural Specialty Code (OSSC), including specific modifications as shown below.
  • ANSI/ASHRAE/IES Standard 90.1 — 2016, including specific modifications as shown below
These provisions are Chapter 13 of the Oregon Structural Specialty Code (OSSC) for commercial energy compliance and shall be referred to herein as "this code." The OSSC is referred to herein as the "Building Code." Sections E102 through E104 are specific to this code and additional to the requirements of Chapter 1 of the Building Code.
This code applies to buildings designed and constructed under the Building Code.

Exception: R-2, R-3, and R-4 occupancies, three stories and fewer above finished grade, shall comply with the multi-family energy provisions in Part II of this code
This code shall regulate the design and construction of buildings for the effective use of energy. This code is intended to provide flexibility to permit the use of innovative approaches and techniques to achieve the effective use of energy. This code is not intended to abridge safety, health or environmental requirements contained in other applicable codes or ordinances.
This code is administered and enforced under the provisions and authority granted in Chapter 1 of the Building Code with the energy efficiency specific Sections E101 through E104 of this code.
ANSI/ASHRAE/IES Standard 90.1-2016 shall serve as the construction provisions for this code. ANSI/ASHRAE/IES Standard 90.1-2016 shall be referred to herein as "Standard 90.1." The administrative and enforcement provisions of Standard 90.1, including submittal, inspection and verification, and recording and reporting are superseded by this code, unless specifically noted in these provisions.
Energy efficiency construction shall comply with Section 4.2.1 of Standard 90.1. Normative and informative appendices of Standard 90.1 are only applicable to compliance paths within Standard 90.1.
The following provisions are in addition to the requirements of Section 102 of the Building Code.
Except as specified in Sections E103.2.1 through E103.2.2.3, this code shall not be used to require the removal, alteration or abandonment of, nor prevent the continued use and maintenance of, an existing building or building system lawfully in existence at the time of adoption of this code.
Where unconditioned space or semiheated space in a building is converted to a conditioned space, such conditioned space shall be brought into compliance with the applicable requirements of Standard 90.1 that would apply to the building envelope, heating, ventilating, air-conditioning, service water heating, power lighting, and other systems and equipment of the space as if the building was new.
Additions, alterations, renovations or repairs to an existing building, building system or portion thereof shall conform to the provisions of this code as they relate to energy provisions for new construction without requiring the unaltered portion(s) of the existing building or building system to comply. Additions, alterations, renovations or repairs shall not create an unsafe or hazardous condition or overload existing building systems. An addition shall be deemed to comply with this code if the addition alone complies or if the existing building and addition comply with this code as a single building.
Additions to existing buildings shall comply with Section of Standard 90.1.
Alterations to existing buildings shall comply with Section of Standard 90.1.
The exception to Section of Standard 90.1 shall apply to historic buildings.
The following provisions are in addition to the requirements of Section 107 of the Building Code.
Construction documents shall be of sufficient clarity to indicate the location, nature and extent of the work proposed, and show in sufficient detail pertinent data and features of the building, systems and equipment as herein governed. Details shall include but are not limited to, as applicable, insulation materials and their R-values; fenestration U-factors and SHGCs; system design criteria; mechanical and service water heating system and equipment types, sizes and efficiencies; economizer description; equipment and system controls; fan motor horsepower (hp) and controls; duct sealing, duct and pipe insulation and location; daylight areas on floor plans; lighting fixture schedule with wattage and control narrative; air sealing details; and COMcheck compliance report or equivalent State of Oregon Building Codes Division form. Plans and specifications shall include requirements for submittal information required by Sections 5.7, 6.7, 7.7, 8.7, and 9.7 of Standard 90.1. The building official shall not require or expect physical copies of record drawings, manuals, test reports, or energy reporting.

Exception: The building official is authorized to waive the requirements for construction documents, COMcheck reports, or other supporting data if the code official determines these are not necessary to confirm compliance with this code.
Construction documents for new buildings shall include the Oregon Zero Energy Ready Compliance Form, including a ZERO Code Calculator report (See ZERO-Code.org/energy-calculator/).
Note: For reference only. Not adopted by the State of Oregon, Building Codes Division, as part of the state building code. The Oregon Department of Energy administers the 1.5% for Green Energy Technology program for public buildings. New construction and major renovation projects for public buildings are required to evaluate and install Green Energy Technology and report to the Oregon Department of Energy in accordance with Oregon Revised Statute (ORS) Chapter 279C, Section 279C.527- 528 and Oregon Administrative Rule (OAR) Chapter 330, Division 135. See Oregon.gov/energy
The following provisions are in addition to the requirements of Section 110 of the Building Code.
Inspections shall be made to determine compliance with Chapter 13 and shall include, but not be limited to, inspections for: envelope air sealing, envelope insulation R-values and U-factors, fenestration U-factor, duct system insulation R-value, and HVAC and water-heating equipment efficiency. Inspection and verification sections included in Standard 90.1 are not enforceable under this code, unless specifically included in this section.
The terms, abbreviations, and acronyms defined in Chapter 3 of Standard 90.1 shall apply to this code where it is not defined in Section 201.2 of the Building Code or in Section E201.2 of this code.

purchased energy rates: costs for units of energy or power purchased at the building site. These costs may include energy costs as well as costs for power demand as determined by the adopting authority. Energy unit costs posted by the adopting authority shall be used in energy cost budget calculations.

rating authority: the organization or agency that adopts or sanctions use of Normative Appendix G when quantifying performance that exceeds requirements of this standard.

Transverse joints are connections of two-duct sections oriented perpendicular to airflow.

semiheated space: an enclosed space within a building that is heated by a heating system whose output capacity is greater than or equal to 3.4 Btu/h•ft2 of floor area but is not a conditioned space.
