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 these shall be verified by the plans examiner.
Whenever any of the special allowance exceptions (footnotes in Standards Table 140.6-C) are claimed, the compliance software shall make an entry on the compliance forms to indicate that verification is required.
With the tailored lighting method, the software shall make an entry in the special features section on the California compliance forms that the tailored lighting method has been used to determine the lighting power for this space and that all necessary prescriptive tailored lighting forms and worksheets documenting the lighting and its justification shall be provided as part of the compliance documentation and be approved independently.
3.2.2.2 Indoor Lighting Power (see 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 residential 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, 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 PERF-1. 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 Complete Building Method
The Complete Building method triggers special reporting requirements. The compliance software shall report the following on the compliance form:
“The Complete Building method requires that at least 90% of the building contain conditioned space, and that at least 90% of the building conform to the building type classification. This condition must be verified by the building official.”
3.2.2.4 Design Illumination Setpoint
Spaces that have low design illuminance levels, below the ranges specified in Appendix 5.4A, shall provide documentation that show the design illuminance to be used as the daylight illumination setpoint.
If the lighted façade area exceeds exterior wall area or if door linear footage exceeds 25% of building perimeter, the software shall produce a warning.
.
3.2.4.1 Equipment Sizing
When the 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.
3.2.4.2 Equipment Performance Curves
An exceptional condition must be noted if the user enters performance data for DX equipment greater than 135,000 Btu/h.
For equipment with a capacity less than or equal to 135,000 Btu/h, but larger than 65,000 Btu/h, the user may not enter data on the temperature dependent equipment performance. However, the compliance software vendor may work with manufacturers to collect such data and build this data into the compliance software. The user may either select equipment for which the compliance software vendor has collected or use the defaults.
3.2.4.3 Process and Filtration Pressure Drop Allowance
Any non-zero value entered for supply fan process and filtration pressure drop shall be 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.
3.2.4.4 Natural Ventilation Specified
Any time 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 exception in section of the 120.1 of the Standards must be met:
1. Natural ventilation.
A. 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..
B. The means to open required operable openings shall be readily accessible to building occupants whenever the space is occupied.
