The 2020 New York State Energy Conservation Code (NYSECC) is based on the 2018 International Energy Conservation Code (IECC) and ASHRAE 90.1-2016 - as modified by the State of New York. The 2020 NYCECC further amends the 2020 NYSECCC to address the unique and dense construction environment of New York City and to align with the New York State Energy Research and Development Authority’s NYStretch Energy Code-2020 as per Section 28-1001.3.3 of the Administrative Code. According to section C406.7 of the New York City Energy Conservation Code, different buildings are classified as follows:
Group R-1: Boarding houses, hotels, or motels.
Group I-2: Hospitals, psychiatric hospitals, and nursing homes.
Group A-2: Restaurants and banquet halls or buildings containing food preparation areas.
Group F: Laundries.
Group R-2: Buildings with residential occupancies.
Group A-3: Health clubs and spas.

1. Wall U-values
2. Roof U-values
3. Window U-values and SHGC
4. Skylights U-value and SHGC
5. Lighting Power Density
Cove.tool Assumptions (all engineering inputs can be easily edited by the user):
Referring to the PNNL prototype models, the wood framed walls with the attic roof are assumed for a small office building and steel framed walls with insulation entirely above deck are assumed for all other commercial building types in cove.tool.
The fixed framing windows are assumed for all building types.
Window SHGC value is picked assuming the Projection Factor(PF) is less than 0.2.
