Part 1 — Scope and Application

101.1 Title

AMENDMENT
This section has been amended at the state or city level.
This code shall be known as the Oregon Energy Efficiency Specialty Code, and may be cited as such. It is referred to herein as "this code."

101.2 Scope

AMENDMENT
This section has been amended at the state or city level.
This code applies to residential and commercial buildings designed and constructed under the Building 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.
Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall govern.
Except as specified in this chapter, 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.

AMENDMENT
This section has been amended at the state or city level.
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 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.

Exception: The following need not comply provided the energy use of the building is not increased:
  1. Storm windows installed over existing fenestration.
  2. When 25 percent or less of the glazing in any one wall is being replaced, it may be replaced with glazing that has a U-factor and SHGC equal to or better than the existing glazing.
  3. Glass only replacements in an existing sash and frame.
  4. Existing ceiling, wall or floor cavities exposed during construction provided that these cavities are filled with insulation.
  5. Construction where the existing roof, wall or floor cavity is not exposed.
  6. Reroofing for roofs where neither the sheathing nor the insulation is exposed. Roofs without insulation in the cavity and where the sheathing or insulation is exposed during reroofing shall be insulated either above or below the sheathing.
  7. Replacement of existing doors that separate conditioned space from the exterior shall not require the installation of a vestibule or revolving door, provided, however, that an existing vestibule that separates a conditioned space from the exterior shall not be removed.
  8. Alterations that replace less than 10 percent of the luminaires or 10 fixtures in a space, provided that such alterations do not increase the installed interior lighting power.
  9. Alterations that replace only the bulb and ballast within up to 50 percent of the existing luminaires in a space provided that the alteration does not increase the installed interior lighting power. Alterations do not include routine maintenance and repair.
