3.2.1.1 Roof Radiative Properties
The user shall enter three-year aged roof reflectance and emittance for roofs that have been certified by the Cool Roof Rating Council. The software shall report the product identification number(s) of any roofing products used on the building, so that aged reflectance and emittance can be verified by the code official.
3.2.2.1 Regulated Interior Lighting Power
Complete lighting plans and space plans are required for the tailored method. Prescriptive compliance forms for the tailored method shall be developed and the plans examiner shall verify them.
Whenever any of the special allowance exceptions (footnotes in Standards Table 140.6-C) are claimed, the compliance software shall indicate on the compliance forms that verification is required.
3.2.2.2 Indoor Lighting Power (see Section 5.4.4)
Compliance software shall print all applicable lighting forms and report the lighting energy use and the lighting level (watts/ft2) for the entire project. Compliance software shall report “no lighting installed” for nonresidential spaces with no installed lighting. Compliance software shall report “default residential lighting” for housing units of high-rise residential buildings and hotel/motel guest rooms.
If the modeled lighting power density (LPD) is different than the actual LPD calculated from the fixture schedule for the building, the compliance software shall model the larger of the two values for sizing the mechanical systems and for the compliance run. Compliance software shall report the larger value on PRF-01. Lighting levels schedules shall be adjusted by any lighting control credit watts, if input by the user.
Lighting power is not modeled in unconditioned spaces that are modeled, but lighting in those spaces is required to meet the prescriptive requirements for regulated unconditioned spaces, such as commercial and industrial storage spaces and parking garages. When these types of spaces are entered, the compliance software must report in the Special Features section that these spaces must comply with the prescriptive requirements for such spaces.
3.2.2.3 Design Illumination Setpoint
Spaces that have low design illuminance levels, below the ranges specified in Appendix 5.4A, shall provide documentation showing the design illuminance to be used as the daylight illumination setpoint.
3.2.3.1 Equipment Sizing
When any proposed equipment size for secondary equipment or central plant equipment does not match the equipment size listed on construction documents, an exceptional condition shall be reported on compliance forms.
3.2.3.2 Process and Filtration Pressure Drop Allowance
Any nonzero value entered for supply fan process and filtration pressure drop are flagged as an exceptional condition in the compliance documentation. An allowance of up to 1” w.g. is provided in the static pressure for process and filtration requirements (such as clean rooms). Any amount may be claimed for the proposed building, but the standard design (baseline) is adjusted by a maximum of 1” w.g.
3.2.3.3 Natural Ventilation Specified
Anytime natural ventilation is specified by the user for the proposed design, either for residential or nonresidential spaces, the software shall report an exceptional condition that the conditions in Section 120.1(b) of the energy standards must be met:
120.1(b)1A. Naturally ventilated spaces shall be permanently open to and within 20 feet of operable wall or roof openings to the outdoors, the openable area of which is not less than 5 percent of the conditioned floor area of the naturally ventilated space. Where openings are covered with louvers or otherwise obstructed, openable area shall be based on the free unobstructed area through the opening.
EXCEPTION to Section 120.1(b)1A: Naturally ventilated spaces in high-rise residential dwelling units and hotel/motel guest rooms shall be open to and within 25 feet of operable wall or roof openings to the outdoors.
120.1(b)1B. The means to open required operable openings shall be readily accessible to building occupants whenever the space is occupied.
