WILKESON ENERGY CODE
Sections:
19.06.010 Adoption of Northwest Energy Code.
19.06.020 Requirements for conversion of buildings to electrical space heating or conditioning.
19.06.030 Application of Washington State Energy Code.
19.06.010 Adoption of Northwest Energy Code.
The Northwest Energy Code, 1987 Edition, as promulgated by the Bonneville Power Administration, is hereby adopted, made part of this chapter and incorporated by reference. This code shall apply to all new residential construction using electrical space heating and all new nonresidential construction using electrical space conditioning and electrical lighting; provided, that the ventilation requirements contained in Section 305 of the 1986 Washington Energy Code (Second Edition), as set forth in WMC 19.06.030, shall apply to buildings. [UDC Ord. dated 7/21/1998].
19.06.020 Requirements for conversion of buildings to electrical space heating or conditioning.
The conversion standard equivalent code amendments to the Model Energy Code, December 24, 1986 Edition, promulgated by the Bonneville Power Administration and compiled with the Northwest Energy Code, 1987 Edition, as presently existing or as subsequently amended, are hereby adopted and incorporated by reference as a part of this chapter. These conversion standards shall apply to any buildings constructed pursuant to a building permit issued on or after the effective date of this chapter, which at the time of initial construction were not required to comply with the standards of the Northwest Energy Code as set out in WMC 19.06.030, when such buildings are subsequently converted to provide electrical space heating or conditioning. [UDC Ord. dated 7/21/1998].
19.06.030 Application of Washington State Energy Code.
The 1986 Washington State Energy Code (Second Edition) is hereby adopted and incorporated by reference except those provisions relating to new residential and nonresidential construction utilizing electrical heating, except that new residential buildings, which are space heated with all other forms of space heating not covered by the Northwest Energy Code, shall be designed to achieve energy use efficiency equivalent to energy use achieved in typical buildings constructed with:
A. Ceilings insulated to a level of R-30 (R value includes insulation only);
B. Walls insulated to a level of R-19 (R value includes insulation only), or constructed with two (2) by four (4) members, R-13 insulation batts, R-3.2 sheathing, and other normal assembly components;
C. Below grade walls, insulated on the interior side, to a level of R-19 (R value includes insulation only), or if insulated on the exterior side, to a level of R-10;
D. Floors over unheated space insulated to a level of R-19 (R value includes insulation only);
E. Slab on grade floors insulated to a level of R-10 at the perimeter;
F. Heat pumps with a minimum heating season performance factor (HSPF) of 6.8 or with all other energy sources with a minimum annual fuel utilization efficiency (AFUE) of seventy-eight (78) percent;
G. Double glazed windows with values not more than U-0.65 when tested according to the procedures of the American Architectural Manufacturers Association (AAMA) standard #D 1503.1-88; and
H. A maximum glazing area of twenty-one (21) percent of the floor area or, for purposes of determining equivalent thermal performance, a maximum glazing area of fifteen (15) percent of the floor area. [UDC Ord. dated 7/21/1998].
19.06.040 Severability.
If any provision of the Northwest Energy Code as amended by this chapter, or any provision of the State Energy Code, or its application to any person or circumstance, is held invalid, the remainder of the Northwest Energy Code or the Washington State Energy Code as adopted by this chapter or their application of the provision to other persons or circumstances is not affected. [UDC Ord. dated 7/21/1998].
