All section numbers in this code shall be deemed to be preceded by the designation "ECC." Administration and enforcement of this code shall be in accordance with Title 28 of the Administrative Code. 101.1.1 Titles. The publication entitled 2020 Energy Conservation Construction Code of New York State shall be known as the "ECCCNYS." The 2016 edition of the Energy Standard for Buildings Except Low-Rise Residential Buildings shall be known as "ASHRAE 90.1-2016." All references in this code to ASHRAE 90.1-2016 shall be deemed to be references to ASHRAE 90.1-2016 (AS AMENDED). The New York State Energy Conservation Construction Code, as contained in Part 1240 of Title 19 of the New York Codes, Rules and Regulations, along with the New York City amendments to such New York State Energy Conservation Construction Code shall be known collectively as the "New York City Energy Conservation Code." 101.2 Scope. This code applies to commercial buildings and residential buildings, as defined in Chapter C2 and Chapter R2 of this code, and the buildings' sites, associated systems and equipment. 101.2.1 References. Where reference is made within this code to the Building Code of New York State, Existing Building Code of New York State, Fire Code of New York State, Fuel Gas Code of New York State, Mechanical Code of New York State, Plumbing Code of New York State, Property Maintenance Code of New York State or Residential Code of New York State, the reference shall be deemed to be to the analogous provision of the New York City Construction Codes (Title 28 of the Administrative Code), the 1968 Building Code (Chapter 1 of Title 27 of the Administrative Code), the New York City Fire Code (Title 29 of the Administrative Code) or the New York City Electrical Code (Chapter 3 of Title 27 of the Administrative Code). 101.2.2 Occupancy classifications.

This code shall regulate the design and construction of buildings for the use and conservation of energy over the life of each building. This code is intended to provide flexibility to permit the use of innovative approaches and techniques to achieve this objective. This code is not intended to abridge safety, health or environmental requirements contained in other applicable codes or ordinances. To the fullest extent feasible, use of modern technical methods, devices and improvements that tend to minimize consumption of energy without abridging reasonable requirements for the safety, health and security of the occupants or users of buildings shall be permitted. As far as may be practicable, the improvement of energy conservation construction practices, methods, equipment, materials and techniques shall be encouraged. Nothing in this section or in any other provision of this code shall be construed to permit the commissioner to approve an application to waive, vary, modify or otherwise alter any provision of this code if such alteration would make such provision less restrictive than a standard or requirement of the New York State Energy Conservation Construction Code, unless the applicant has obtained approval for such alteration pursuant to Section 11-106 of the New York State Energy Law. 101.4 Applicability. The provisions of this code shall apply to the construction of buildings. Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall govern. 101.4.1 Mixed occupancy. Where a building includes both commercial and residential occupancies, each occupancy shall be separately considered and shall meet the applicable provisions of Chapters C2, C3, C4 and C5 for commercial, and Chapters R2, R3, R4, and R5 for residential. 101.5 Compliance.

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 ?-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 ?-value (Chi-Value) in units Btu/hr � �F (W/K).

F = (above-grade thermal boundary wall area)/(above-grade thermal boundary wall area + common wall area) or 0.56, whichever is greater, and where: Thermal boundary wall is any wall that separates conditioned space from unconditioned space or ambient conditions. Above-grade thermal boundary wall is any thermal boundary wall component not in contact with soil. Below-grade boundary wall is any thermal boundary wall in soil contact. Common wall area is the area of walls shared with an adjoining dwelling unit. L and CFA are in the same units.

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 fa�ade 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 fa�ade M East = SHGC multiplier for the East fa�ade 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 fa�ade. Orientation must be determined following Section 5.5.4.5, Fenestration Orientation. 2.
