See the definitions of “Basement” and “Grade plane.” A story is measured as the vertical distance from top to top of two successive tiers of beams or finished floor surfaces and, for the topmost story, from the top of the floor finish to the top of the ceiling joists or, where there is not a ceiling, to the top of the roof rafters.

STORY ABOVE GRADE PLANE. Any story having its finished floor surface entirely above grade plane, or in which the finished surface of the floor next above is:

1.  More than 6 feet (1829 mm) above grade plane; or

2.  More than 12 feet (3658 mm) above the finished ground level at any point.

THERMAL BRIDGE: Thermal bridges are elements that interrupt areas of uniform thermal resistance in the building envelope.

Clear field thermal bridge: an area-based thermal transmittance associated with elements of a building envelope assembly which repeat at regular intervals. Examples of clear field thermal bridges include metal or wood studs, brick ties and cladding attachments such as z-girts.

Linear thermal bridge: a length-based thermal transmittance associated with horizontal, vertical, or diagonal elements within the building envelope and with length measured along the exterior surface of the building envelope. Examples of linear thermal bridges include balconies or floor assemblies which penetrate walls in the building envelope, fenestration perimeter interfaces, parapets, and shelf angles. Linear thermal transmittance is heat flow divided by length and by the temperature difference between the interior and exterior sides of the assembly, represented by a Ψ-value (Psi-Value) in units Btu/hr • ft • °F (W/mK).

Point thermal bridge: an element-based thermal transmittance associated with a discrete element that penetrates the building envelope. Examples of point thermal bridges include a beam penetrating a wall, a column penetrating a roof or floor, and an anchor or connection used to attach an element to the building and not otherwise addressed as a clear field thermal bridge or linear thermal bridge. Point thermal transmittance is heat flow divided by the temperature difference between the interior and exterior sides of the assembly, represented by a Χ-value (Chi-Value) in units Btu/hr • °F (W/K).

1.                     For multifamily, hotel/motel and dormitory building area types, the margin by which the proposed envelope performance factor exceeds the base envelope performance factor shall not be greater than 15%. For compliance with this requirement, the base envelope performance factor shall be calculated using metal framing operable windows. In buildings with window area accounting for 40% or more of the gross wall area, the SHGC of the vertical fenestration on east and west oriented façade may be reduced by the following multiplier to account for the permanent site shading from existing buildings or infrastructure.

M _West = 0.18 + 0.33/WWR

M _East = 0.35 + 0.26/WWR

 

Where:

M _West                      =                      SHGC multiplier for the West façade

M _East                     =                      SHGC multiplier for the East façade

WWR                      =                     the ratio of the proposed vertical fenestration area to the gross wall area in consistent units.

The multiplier may be applied to the rated SHGC of the vertical fenestration which has at least 50% of the area located directly opposite of the shading surfaces and no higher from the street level than the difference between the shading surface height and the shading surface distance from the façade. Orientation must be determined following Section 5.5.4.5, Fenestration Orientation.

2. For all other building area types, the margin by which the proposed envelope performance factor exceeds the base envelope performance factor shall be not greater than 7%. For compliance with this requirement, the base envelope performance factor shall be calculated using metal framing fixed windows.

3. For mixed-use buildings the margin shall be calculated as the gross wall area-weighted average of 1 and 2 above.

b.                     the design energy cost, as calculated in Section 11.5, does not exceed the energy cost budget as calculated by the simulation program described in Section 11.4;

c.                     the energy efficiency level of components specified in the building design meet or exceed the efficiency levels used to calculate the design energy cost; and

d.                     In new buildings 25,000 square feet and greater, the building envelope shall comply with either:

1. Section 5.5, “Prescriptive Building Envelope Option,” or

2. An envelope performance factor shall be calculated in accordance with Appendix C of this standard, and buildings shall comply with one of the following:

i.                      For multifamily, hotel/motel and dormitory building area types, the margin by which the proposed envelope performance factor exceeds the base envelope performance factor shall not be greater than 15%. For compliance with this requirement, the base envelope performance factor shall be calculated using metal framing operable windows. In buildings with window area accounting for 40% or more of the gross wall area, the SHGC of the vertical fenestration on east and west oriented façade may be reduced by the following multiplier to account for the permanent site shading from existing buildings or infrastructure.

                                                               M_West= 0.l8 + 0.33/WWR

                                                               M_East= 0.35 + 0.26/WWR

                                                               Where:

                                                                                    M_West= SHGC multiplier for the West façade

                                                                                    M_East= SHGC multiplier for the East façade

WWR = the ratio of proposed vertical fenestration area to the gross wall area in consistent units

The multiplier may be applied to the rated SHGC of the vertical fenestration which has at least 50% of the area located directly opposite of the shading surfaces and no higher from the street level than the difference between the shading surface height and the shading surface distance from the façade. Orientation must be determined following Section 5.5.4.5, Fenestration Orientation.

ii.                      For all other building area types, the margin by which the proposed envelope performance factor exceeds the base envelope performance factor shall be not greater than 7%. For compliance with this requirement, the base envelope performance factor shall be calculated using metal framing fixed windows.

iii.                      For mixed-use buildings, the margin shall be calculated as the gross wall area-weighted average of items (i) and (ii) above.

When the simulation program does not model a design, material, or device, the authority having jurisdiction may approve an exceptional calculation method to be used to demonstrate compliance with Section 11.

Section 11.5.2 HVAC Systems

Section 11.5.2 - Revise Item c in Section 11.5.2 to read as follows:

c.                     Supply Fan Energy in Certain Package Equipment

Where efficiency ratings include supply fan energy, the efficiency rating shall be adjusted to remove the supply fan energy. For Budget System Types 3, 4, 6, 9, and 11, calculate the minimum COP_nfcooling and COP_nfheating using the equation for the applicable performance rating as indicated in Tables 6.8.1-1 through 6.8.1-4. Where multiple HVAC zones are combined into a single thermal block in accordance with Table 11.5.1, the efficiencies for the budget System Types 6, 8, and 10 taken from Tables 6.8.1-1 through 6.8.1-4, shall be based on 9,000 Btu/hr equipment capacity for residential spaces; otherwise, it shall be based on the capacity of the thermal block divided by the number of HVAC zones. Budget System Types 3, 6, 9 and 11 efficiencies taken from Table 6.8.1-1 through 6.8.1-4 shall be based on the cooling equipment capacity of a single floor when grouping identical floors in accordance with Table 11.5.1. Where a full- and part-load efficiency rating is provided in Tables 6.8.1-1 through 6.8.1-4, the full-load equation below shall be used:

 

COP_nfcooling = 7.84E-8 × EER × Q + 0.338 × EER

COP_nfcooling = -0.0076 × SEER² + 0.3796 × SEER

COP_nfheating = 1.48E-7 × COP₄₇ × Q + 1.062 × COP₄₇

(applies to heat pump heating efficiency only)

COP_nfheating = -0.0296 × HSPF² + 0.7134 × HSPF

where COP_nfcooling and COP_nfheating are the packaged HVAC equipment cooling and heating energy efficiency, respectively, to be used in the budget building design, which excludes supply fan power, and Q is the AHRI-rated cooling capacity in Btu/h. If Q is greater than 760,000 Btu/hr, use 760,000 Btu/h in the calculation.

c. In new buildings 25,000 square feet and greater, the building envelope shall comply with either:

1. Section 5.5, “Prescriptive Building Envelope Option,” or

2. An envelope performance factor shall be calculated in accordance with Appendix C of this standard, and buildings shall comply with one of the following:

i.                      For multifamily, hotel/motel and dormitory building area types, the margin by which the proposed envelope performance factor exceeds the base envelope performance factor shall not be greater than 15%. For compliance with this requirement, the base envelope performance factor shall be calculated using metal framing operable windows. In buildings with window area accounting for 40% or more of the gross wall area, the SHGC of the vertical fenestration on east and west oriented façade may be reduced by the following multiplier to account for the permanent site shading from existing buildings or infrastructure.

                                                               M_West = 0.l8 + 0.33/WWR

                                                               M_{Eas t}= 0.35 + 0.26/WWR

                                                               Where:

                                                                                    M_West = SHGC multiplier for the West façade

                                                                                    M_East = SHGC multiplier for the East façade

WWR = the ratio of proposed vertical fenestration area to the gross wall area in consistent units

The multiplier may be applied to the rated SHGC of the vertical fenestration which has at least 50% of the area located directly opposite of the shading surfaces and no higher from the street level than the difference between the shading surface height and the shading surface distance from the façade. Orientation must be determined following Section 5.5.4.5, Fenestration Orientation.

ii.                      For all other building area types, the margin by which the proposed envelope performance factor exceeds the base envelope performance factor shall be not greater than 7%. For compliance with this requirement, the base envelope performance factor shall be calculated using metal framing fixed windows.

iii.                      For mixed-use buildings, the margin shall be calculated as the gross wall area-weighted average of i) and ii) above.

a.                     Separate model of each of these assemblies within the energy simulation model.

b.  Separate calculation of the U-factor for each of these assemblies. The U-factors of these assemblies are then averaged with larger adjacent surfaces using an area- weighted average method. This average U-factor is modeled within the energy simulation model.

Any other building envelope assembly that covers less than 5% of the total area of that assembly type (e.g., exterior walls) need not be separately described, provided that its U-factor is similar to an assembly being modeled. If not separately described, the area of a building  envelope assembly shall be added to the area of an assembly of that same type with the same orientation and thermal properties.

When the total area of penetrations from through-the-wall mechanical equipment or equipment listed in Table 6.8.1-4 exceeds 1% of the opaque above-grade wall area, the mechanical equipment penetration area shall be calculated as a separate wall assembly with a default U-factor of 0.5.
