subch. I of ch. SPS 322 Subchapter I — Scope and Application
SPS 322.01 SPS 322.01 Scope.
SPS 322.01(1)(1) This chapter applies to all one- and 2-family dwellings covered by this code that use any amount of non-renewable energy for heat generation.
SPS 322.01 Note Note: Non-renewable energy sources used for heat distribution only will not require compliance with this chapter.
SPS 322.01 Note Note: Although the actual source of heat delivered by a heat pump is renewable, a dwelling using a heat pump is not exempt from the requirements of this chapter due to the required input of electricity to run the pump and compressor.
SPS 322.01(2) (2) The equipment efficiency standards in this chapter apply to all one- and 2-family dwellings covered by this code that use the respective equipment.
SPS 322.01(3)(a)(a) The vapor retarder requirements under s. SPS 322.38 and the moisture control and ventilation requirements under s. SPS 322.39 apply to any dwelling with insulation installed, whether or not the insulation is required under this code.
SPS 322.01(3)(b) (b) The vapor retarder requirements under s. SPS 322.38 do not apply to an unheated space, such as an attached, unheated garage.
SPS 322.01 History History: CR 08-043: cr. Register March 2009 No. 639, eff. 4-1-09; correction in (3) made under s. 13.92 (4) (b) 7., Stats., Register December 2011 No. 672; CR 15-041: renum. (3) to (3) (a), cr. (3) (b) Register December 2015 No. 720, eff. 1-1-16.
SPS 322.02 SPS 322.02 Application.
SPS 322.02(1)(1) This chapter is not intended to conflict with any safety or health requirements. Where a conflict occurs, the safety and health requirements shall govern.
SPS 322.02(2) (2) This chapter allows the designer the option of using various methods to demonstrate compliance with thermal performance requirements. The designer shall identify on the plan submittal form what method or subchapter is being used, and indicate the design criteria and how it is being applied. Unless specifically exempted, all requirements of this chapter apply regardless of the method used.
SPS 322.02 History History: CR 08-043: cr. Register March 2009 No. 639, eff. 4-1-09.
subch. II of ch. SPS 322 Subchapter II — Definitions
SPS 322.10 SPS 322.10 Definitions.
SPS 322.10(1)(1) “ Air-impermeable" means having an air permeance less than or equal to 0.02 L/s-m2 at a pressure differential of 75 pascals when tested according to ASTM E 2178 or ASTM E 283.
SPS 322.10(2) (2) “Conditioned floor area" means the sum of areas of all floors in conditioned space in the structure, including basements, cellars, and intermediate floored levels measured from the exterior faces of exterior walls or from the center line of interior walls, excluding covered walkways, open roofed-over areas, porches, exterior terraces or steps, chimneys, roof overhangs and similar features.
SPS 322.10(3) (3) “Conditioned space" means space within the dwelling thermal envelope which is provided with heated air or surfaces to provide a heated space capable of maintaining the temperature of the space to at least 50°F at design conditions.
