TOWN OF ITHACA
LOCAL LAW NO. 1 OF THE YEAR 2023
A LOCAL LAW AMENDING CHAPTER 144 TO THE TOWN OF ITHACA CODE,
TITLED “ENERGY CODE SUPPLEMENT”
Be it enacted by the Town Board of the Town of Ithaca as follows:
Section 1. Chapter 144 (Energy Code Supplement) of the Town of Ithaca Code is
amended as follows:
A. Section 144-302 (General definitions) is amended by replacing the “FLOOR AREA”
and “MAJOR RENOVATIONS” definitions with the following definitions, and by adding a
definition for “HEATING PLANT,” all reading as follows:
“FLOOR AREA – The total floor surface of all levels as measured from the inside
perimeter of the exterior or separation walls, exclusive of vent shafts, courts, and un-conditioned
spaces.”
“HEATING PLANT – One or more appliances that serve as the primary source of
heating for the building or space, whether located in the building or not.”
“MAJOR RENOVATION – Any construction or renovation to an existing structure,
building, separated occupancy, tenant space, or unit under consideration, other than a repair or
addition, that meets these two requirements:
A. The WORK AREA exceeds seventy-five percent of the FLOOR AREA, and
B. The proposed work involves two or more of the following:
1. Replacement or new installation of fifty percent or more of the rated capacity of
the HEATING PLANT that serves the FLOOR AREA. Changes to air
distribution, exhaust, or air conditioning systems are not considered renovations
to the HEATING PLANT.
2. Construction that involves disassembly or uncovering of greater than fifty percent
of the area of the above-grade portion(s) of the BUILDING THERMAL
ENVELOPE that serves the FLOOR AREA.
3. Changes to lighting, including but not limited to new installation, replacement,
relocation, or removal, of lamps, lighting, or other illumination fixtures
throughout fifty percent or more of the FLOOR AREA. FLOOR AREA that is not
currently lit, and is not proposed to be lit, shall not count toward the fifty percent
calculation.”
B. Section 144-C402.5.1 (OP1 Development density) and the two introductory sentences
in Section 144-C402.5.2 (OP2 Walkability) are deleted and replaced with the following:
“144-C402.5.1 OP1 Development density
One point may be earned according to the requirements below.
Adopted 2023-01-09 1
Restrictions: A maximum of three points total may be earned using up to two (maximum) of
the following: OP1 Development Density, OP2 Walkability, and OP3 Electric Vehicle Parking
Spaces.
144-C402.5.1.1
One point shall be earned if (DU + CA) > (7 x Acreage), where:
DU = the number of all Residential dwelling units and/or sleeping units on the entire parcel
occupied by the building
CA = the FLOOR AREA of all Commercial space, measured in units of 1,000 square feet, on
the entire parcel occupied by the building
Acreage = the land area, measured in acres, of the entire parcel occupied by the building.
144-C402.5.1.2
DU shall include all dwelling units and/or sleeping units on the parcel occupied by the building,
including those in existing buildings. CA shall include all Commercial space on the parcel
occupied by the building, including that in existing buildings. CA shall not include common
areas serving only dwelling units or other Residential space. Acreage shall include all land area
on the parcel occupied by the building.
Example Calculation - for informational purposes only
Mixed Use Development
Residential units: 12 apartments DU = 12
Commercial space: 10,000 sq ft CA = 10
Parcel acreage: 1.5 acres Acreage = 1.5
DU + CA = 12 + 10 = 22
7 x Acreage = 7 x 1.5 = 10.5
22 > 10.5
1 point may be earned.
144-C402.5.2 OP2 Walkability
One point may be earned according to the requirements below.
Restrictions: A maximum of three points total may be earned using up to two (maximum) of
the following: OP1 Development Density, OP2 Walkability, and OP3 Electric Vehicle Parking
Spaces.”
C. The two introductory sentences in Section 144-C402.5.3 (OP3 Electric vehicle parking
spaces) are deleted and replaced with the following:
“144-C402.5.3 OP3 Electric vehicle parking spaces
Up to two points may be earned for installing ELECTRIC VEHICLE PARKING SPACE(s)
and related infrastructure that meet the requirements of this subsection.
Restrictions: A maximum of three points total may be earned using up to two (maximum) of
the following: OP1 Development Density, OP2 Walkability, and OP3 Electric Vehicle
Parking Spaces.”
D. Table 144-C402.5.3.1 (1) (Required Number of Electric Vehicle Parking Spaces) and
Table 144-C402.5.3.1 (2) (Sample Calculation for required number of EV Parking Spaces) are
