Area 4 * 1.3 W/ft2)
|
Where:
|
Retail Area 1 = The floor area for all products not listed in
Retail Area 2, 3 or 4.
|
Retail Area 2 = The floor area used for the sale of vehicles,
sporting goods, and small electronics.
|
Retail Area 3 = The floor area used for the sale of furniture,
clothing, cosmetics, and artwork.
|
Retail Area 4 = The floor area used for the sale of jewelry,
crystal, and china.
|
Exception: Other merchandise categories
are permitted to be included in Retail Areas 2 through 4, provided
that justification documenting the need for additional lighting power
based on visual inspection, contrast, or other critical display is
approved by the Code Enforcement Officer.
|
Step 1: Calculate Renewable Energy Production
|
The Renewable Energy Production (REP) is the projected annual
energy production of the renewable energy system, expressed in kilowatt-hours
per year (kWh/yr). For thermal systems, the conversion 1 kWh = 3.412
kBtu shall be used.
|
Step 2: Calculate the Number of Points Earned The
number of points earned for a renewable energy system is based on
the directly heated floor area of the building it serves. Points shall
be earned based on a weighted average related to residential and commercial
floor area, as described in Equation 144-4-2. For purposes of this
144-C402.4.1, residential space shall include dwelling units and common
areas that serve only dwelling units.
|
Equation 144-4-2: Minimum Renewable
Energy Production needed to earn each point =
|
(1.2 kWh/ft2 x RA) +
(2.4 kWh/ft2 x CA)
|
CA = Directly heated floor area of Commercial space
(ft2)
|
RA = Directly heated floor area of Residential space
(ft2)
|
Note: For buildings that have no residential space,
set RA equal to zero.
|
Example Calculation - For Informational Purposes Only
|
Assumptions: Mixed-use building with 2,000 ft2 of residential directly heated floor area and 5,000 ft2 of commercial directly heated floor area. A 25 kW
solar array is being used.
|
Step 1: Using the PVWatts Calculator, it is projected that the
25 kW solar array will produce 30,000 kWh/year.
|
Renewable Energy Production is 30,000 kWh/year.
|
Step 2: Using Equation 144-4-2:
|
Minimum REP needed for each point = (1.2 kWh/ft2 x RA) + (2.4 kWh/ft2 x
CA)
|
Minimum REP needed for each point = (1.2 kWh/ft2 x 2,000 ft2) + (2.4 kWh/ft2 x 5,000 ft2)
|
Minimum REP needed for each point = 2,400 kWh + 12,000 kWh
|
Minimum REP needed for each point = 14,400 kWh
|
Using the assumptions for this building and renewable energy
system, two points may be earned.

For 1 to 24 Dwelling Units:
EV Spaces required for each point SR = 0.081 x DU
|
For all building sizes use the equation:
EV Spaces required for each point SC = 0.151 x CA
| ||||
For 25 or more Dwelling Units:
SR = [(0.13 x DU) + 1] ÷ 1.853
| |||||
Complete calculations for Residential and Commercial space separately,
add results, then round up to the nearest whole number. SR + SC =
ST (Total EV Parking Spaces required). To calculate how to earn two
points, refer to Table C402.5.3.1(2) or Table R502.5.3.1(2) Sample
Calculation for required number of EV Parking Spaces.
|
Table 144-C402.5.3.1 (2)
Sample Calculation for Required Number of EV Parking Spaces
|
---|
Sample Calculation
44,300 sq ft mixed-use building. 26 Dwelling Units (DU) and
6,000 sq ft Commercial Area (CA).
|
To earn one point
SR = [(0.13 x 26) + 1] ÷ 1.853
SR = (3.38 + 1) ÷ 1.853
SR = 4.38 ÷ 1.853 = 2.364
2.364 EV spaces are required for Residential portion
|
SC = 0.151 x 6
SC = 0.906
0.906 EV spaces are required for Commercial portion
|
ST = SR + SC rounded up
ST = 2.364 + 0.906 = 3.27, round up
4 EV spaces are required for the building to earn one
point.
|
To earn two points
SR = 2.364 x 2 = 4.728
SC = 0.906 x 2 = 1.812
ST = SR + SC rounded up
ST = 4.728 + 1.812 = 6.54, round up
7 EV spaces are required for the building to earn two
points.
|
The 50% threshold relates to the total combined surface area
of all listed building elements. Any individual elements, or portions
thereof, may be replaced, as long as the total surface area of all
the unaltered elements is at least 50% of the starting (pre-construction)
total surface area of the elements.

Example Calculation - For Informational Purposes Only
|
Duplex, building contains 3,100 square feet of directly heated
floor area, two dwelling units (3 bedrooms each)
|
From Table 144-R502.3.1.1
Maximum home size allowed to receive 1 point for 3-BR units:
1,870 square feet
Total Building Size Allowance = (2 x 1,870 square feet) = 3,740
square feet
Building size of 3,100 square feet does not exceed size
allowance, so 1 point can be earned.
|
From Table 144-R502.3.1.1
Maximum home size allowed to receive two points for 3-BR units:
1,540 square feet
Total Building Size Allowance = (2 x 1,540 square feet) = 3,080
square feet
Building size of 3,100 square feet exceeds size allowance,
so two points cannot be earned.
|
Equation 144-5-2:
|
Total Unit Size Allowance =
|
[(Number of studio units in the building) x (Dwelling unit size
allowance for studio units listed in Table 144-R502.3.1.2)] +
|
[(# of 1-BR units in the building) x (Dwelling unit size allowance

Step 1: Calculate Renewable Energy Production
|
The Renewable Energy Production (REP) is the projected annual
energy production of the renewable energy system, expressed in kilowatt-hours
per year (kWh/yr). For thermal systems, the conversion 1 kWh = 3.412
kBtu shall be used.
|
Step 2: Calculate the Number of Points Earned
|
The number of points earned for a renewable energy system is
based on the directly heated floor area of the building it serves.
Points shall be earned based on a weighted average related to residential
and commercial floor area, as described in Equation 144-5-2. For purposes
of this 144-R502.4.1, residential space shall include dwelling units
and common areas that serve only dwelling units.
|
Equation 144-5-2: Minimum Renewable
Energy Production needed to earn each point = (1.2 kWh/ft2 x RA) + (2.4 kWh/ft2 x
CA)
|
CA = Directly heated floor area of Commercial space
(ft2)
|
RA = Directly heated floor area of Residential space
(ft2)
|
Note: For buildings that have no commercial space,
set CA equal to zero.
|
Example Calculation - For Informational Purposes Only
|
Assumptions: Mixed-use building with 2,000 ft2 of residential directly heated floor area and 5,000 ft2 of commercial directly heated floor area. A 25 kW
solar array is being used.
|
|
Step 1: Using the PVWatts Calculator, it is projected that the
25 kW solar array will produce 30,000 kWh/year.
|
Renewable Energy Production is 30,000 kWh/year
|
|
Step 2: Using Equation 144-5-2:
|
Minimum REP needed for each point = (1.2 kWh/ft2 x RA) + (2.4 kWh/ft2 x
CA)
|
Minimum REP needed for each point = (1.2 kWh/ft2 x 2,000 ft2) + (2.4 kWh/ft2 x 5,000 ft2)
|
Minimum REP needed for each point = 2,400 kWh + 12,000 kWh
|
Minimum REP needed for each point = 14,400 kWh
|
Using the assumptions for this building and renewable energy
system, two points may be earned.

For 1 to 24 Dwelling Units:
EV Spaces required for each point SR = 0.081 x DU
|
For all building sizes use the equation:
EV Spaces required for each point SC = 0.151 x CA
| ||||
For 25 or more Dwelling Units:
SR = [(0.13 x DU) + 1] ÷ 1.853
| |||||
Complete calculations for Residential and Commercial space separately,
add results, then round up to the nearest whole number. SR + SC =
ST (Total EV Parking Spaces required). To calculate how to earn two
points, refer to Table C402.5.3.1(2) or Table R502.5.3.1(2) Sample
Calculation for required number of EV Parking Spaces.
|
Table 144-R502.5.3.1(2)
Sample Calculation for Required Number of EV Parking Spaces
|
---|
Sample Calculation
44,300 sq ft mixed-use building. 26 Dwelling Units (DU) and
6,000 sq ft Commercial Area (CA).
|
To earn one point
SR = [(0.13 x 26) + 1] ÷ 1.853
SR = (3.38 + 1) ÷ 1.853
SR = 4.38 ÷ 1.853 = 2.364
2.364 EV spaces are required for Residential portion
|
SC = 0.151 x 6
SC = 0.906
0.906 EV spaces are required for Commercial portion
|
ST = SR + SC rounded up
ST = 2.364 + 0.906 = 3.27, round up
4 EV spaces are required for the building to earn one
point.
|
To earn two points
SR = 2.364 x 2 = 4.728
SC = 0.906 x 2 = 1.812
ST = SR + SC rounded up
ST = 4.728 + 1.812 = 6.54, round up
7 EV spaces are required for the building to earn two
points.
|
The 50% threshold relates to the total combined surface area
of all listed building elements. Any individual elements, or portions
thereof, may be replaced, as long as the total surface area of all
the unaltered elements is at least 50% of the starting (pre-construction)
total surface area of the elements.
