PSC 136.06
PSC 136.06 Conservation standards for conversion of an existing residential structure to an electric spaceheating system. PSC 136.06(1)(1)
The provisions of this section shall apply only to those investor-owned utilities set forth below:
PSC 136.06(2)
(2) Nothing in s.
PSC 136.06 shall preclude special and individual consideration being given to exceptional or unusual situations. The rule may be modified or waived by the public service commission in particular cases whenever it is shown to be impracticable for special reasons. Upon due investigation of the facts and circumstances involved and after hearing if required, the commission may order requirements as to individual utilities or service which shall be lesser, greater, other, or different from those provided in the rules of this section.
PSC 136.06(3)
(3) Before electric spaceheating service may be furnished to an existing residential structure converting to an electric spaceheating system, each utility listed in sub.
(1) shall perform an energy audit and require that the following conservation standards be met:
PSC 136.06(3)(a)
(a) Ceiling or attic. If the structure has ceiling or attic insulating material with insulation value less than R-19, the customer shall install insulation to a level of R-38. If inadequate space exists between ceiling and roof to install insulation to the level of R-38, then the customer shall install as much insulation as space permits.
PSC 136.06 Note
Note: If the structure's ceiling or attic is insulated to a value of not less than R-11 and the customer chooses to add batt insulation, the additional insulation need only have a value of R-19.
PSC 136.06(3)(b)
(b) Sill box. Sill box area insulation shall be installed to a level of R-19, unless physically impractical.
PSC 136.06(3)(c)
(c) Floor. In accessible areas, floor insulation over vented crawl spaces or unheated basements shall be installed to a level of R-19. In heated crawl spaces, insulation with an R factor of 5 shall be installed on the walls.
PSC 136.06(3)(d)
(d) Unheated areas. In unheated areas, insulation shall be installed on all heating ducts, cold air returns, and hot water pipes.
PSC 136.06(3)(f)
(f) Outside doors. Each door exposed to the outside atmosphere shall have a storm door or equivalent insulated door.
PSC 136.06(3)(g)
(g) Weatherstripping and caulking. Weatherstripping shall be installed on all movable doors and windows exposed to an unheated space. Caulking shall be installed whenever two different materials or parts of a structure meet, such as areas around chimney openings, around windows and doors, and similar areas.
PSC 136.06(3)(h)
(h) Side walls. Where no insulation exists in accessible outside walls, side wall insulation of R-11 shall be installed.
PSC 136.06(3)(i)
(i) Ventilation. A free ventilating area of not less than 1/300 of the horizontal area shall be installed above ceiling or attic insulation.
PSC 136.06 Note
Note: One-half of venting near the eaves and the other half near the top of the roof is recommended. Where no vapor barrier is present, a free ventilating area of not less than 1/150 of the horizontal area is recommended.
PSC 136.06(3)(j)
(j)
Substituted standards. For existing residential structures unable to meet the conversion standards required by this section, other methods of energy conservation may be substituted if the energy savings are equivalent. Substitutions shall be based on heat loss calculations performed by the utility.
