As used in this article, the following terms shall have the
meanings indicated:
ADDITION
An extension or increase in heated floor area, number of
stories or height of a building or structure.
BUILDING
Any structure utilized or intended for supporting or sheltering
any occupancy.
CONSTRUCTION
Work subject to the provisions of City Code Chapter
146, Building Code Enforcement.
DIRECTOR or DIRECTOR OF PLANNING
Shall refer to the Director of Planning and Development,
or where not noted, but in the Director's discretion, may also include
the Director's designee.
DIRECTLY HEATED SPACE
An area or room that is enclosed within the building thermal
envelope and is directly heated using fossil fuel, electricity, or
biomass as the energy source. Spaces are indirectly heated (and not
directly heated) where they connect through openings with heated spaces,
where they are separated from heated spaces by uninsulated walls,
floors or ceilings, or where they contain uninsulated ducts, piping
or other sources of heating using fossil fuel, electricity, or biomass.
FINAL APPROVED IECS PLAN
A project's final plan for compliance with the Ithaca Energy
Code Supplement, as approved by the Director of Planning or designee.
FLOOR AREA
The total square footage of all levels as measured from the
inside finished surface of the walls, but excluding outside courts,
unconditioned garages, and uninhabitable crawl spaces and attics.
FOSSIL FUELS
An energy source formed in the Earth's crust from decayed
organic material. The common fossil fuels are petroleum, coal, and
natural gas. For purposes of this IECS, fossil fuels shall also include
common extracts, derivatives, and products of fossil fuels, including
but not limited to propane, kerosene, and gasoline.
HEATED FLOOR AREA
The horizontal projection of the floors associated with the
heated space.
ITHACA ENERGY CODE SUPPLEMENT
The regulations governing implementation of this article
setting forth the point requirements and criteria and compliance paths.
Also referred to as the IECS or supplement.
MAJOR RENOVATION
Construction or renovation to an existing structure other
than a repair or addition, where the work area exceeds 75% of the
floor area, and two or more of the following occur:
A.
Replacement or new installation of a heating plant or system
(e.g., boiler, furnace, or other major system). Changes to ventilation
and air conditioning systems are not considered renovations of the
heating system.
B.
Construction that involves disassembly of greater than 50% of
the area of the above-grade portion(s) of the building thermal envelope.
C.
Changes to, including but not limited to new installation, replacement,
relocation, or removal of, lamps, lighting, or other illumination
fixtures in greater than 50% of the building floor area. Space within
a building that is not currently lit, and is not proposed to be lit,
shall not count toward the 50% calculation.
PROJECT
Any land use activity or construction which requires a building
permit from the Building Division and will result in changes to the
physical condition, appearance or type of use, or intensity of use,
of property.
RENEWABLE ENERGY CREDIT
A tradable instrument that represents the environmental attributes
of one megawatt-hour of renewable electricity generation and is transacted
separately from the electricity generated by the renewable energy
source. Also known as REC, renewable energy certificate, energy attribute
and energy attribute certificate.
RENEWABLE ENERGY SYSTEMS
Includes any energy systems producing electricity from solar,
wind, or hydroelectric, or thermal energy from solar, geothermal,
or hydrothermal resources, but shall not include systems producing
thermal energy absorbed from or rejected to outdoor air/ground/water
and used in conjunction with heat pumps.
THERMAL ENVELOPE
The insulated exterior walls (above and below grade), floors,
ceilings, roofs, and any other building element assemblies that enclose
heated space or provide a boundary between heated space and unheated
space.
WORK AREA
That portion or portions of a building consisting of all
reconfigured spaces as indicated on the construction documents. Work
area excludes other portions of the building where incidental work
entailed by the intended work must be performed and portions of the
building where work not initially intended by the owner is specifically
required by the provisions of state existing building code.
The Director of Planning or designee is hereby authorized to
make minor amendments and non-substantive revisions to the Ithaca
Energy Code Supplement as deemed necessary from time to time, which
may include clarifications concerning point values or additional point
classifications of individual energy criteria. Substantive changes
to point values or the classifications or amendments to the phases,
as described above, shall require Common Council approval.
If any section, paragraph or provision of this article shall
be determined to be invalid, such invalidity shall apply only to the
section, paragraph or provision adjudged invalid, and the rest of
this article shall remain valid and effective.
