The NYC Energy Code likewise sets prerequisites for materials, frameworks and hardware, which must all be legitimately recognized and marked with the goal that consistence can be evaluated. Section R4 sets up the vitality productivity necessities for private structures, giving three ways to deal with consistence.
Choice #1-Complying with Sections R401 through R404
This is the regular code-based approach, and every one of the areas sets up necessities for various building components:
Area R401 manages general necessities. Structures must have a lasting testament with key vitality effectiveness measurements, for example, R-values, U-values and sunlight based warmth pick up coefficients (SHGC), and additionally the sort and proficiency of warming and cooling hardware.
Segment R402 centers on the building envelope, setting up necessities and criteria for protection, fenestration and air spillage.
Segment R403 centers around building frameworks. This incorporates control gadgets, boilers, warm pumps, channels, ventilation and funneling, among others.
Segment R404 covers the necessities for power and lighting.
Note that a few necessities are named as Mandatory and others are Prescriptive. Notwithstanding, to agree to the vitality code through this approach, all prerequisites must be met in any case.
Choice #2 – Section R405 Plus Only Mandatory Requirements for R401 through R404
Area R405 enables the working to conform to vitality effectiveness prerequisites through a mimicked vitality execution examination. On the off chance that this approach is tailed, it is just important to meet the prerequisites marked as Mandatory in segments R401 through R404.
Choice #3 – Energy Rating Index (ERI) as Detailed in Section R406
Similarly as with the second alternative, with this one it is important to meet every single Mandatory necessity in Sections R401 through R404. At that point, code consistence is accomplished through an Energy Rating Index (ERI) investigation.
Part R5 puts forward the necessities for ventures did in existing structures, and is likewise separated by segments:
Area R501 – General
Area R502 – Additions
Area R503 – Alterations
Area R504 – Repairs
Area R505 – Change of Occupancy or Use
Now and again, necessities from Chapter R4 may likewise apply. In any case, when this is the situation, it is specified unequivocally in the comparing area. Memorable structures are absolved from every one of the necessities in this section of the NYC Energy Code.
NYC Energy Code Requirements for Commercial Buildings
The general conditions for outline and reproduction are the same utilized for private structures: New York City is in Climate Zone 4A, the greatest plan temperature for warming burden is 72°F, and the base outline temperature for cooling load is 75°F. The code additionally sets up naming prerequisites for all materials, frameworks and gear utilized, which are important to evaluate consistence.
Part C4 centers around business vitality effectiveness, and gives three contrasting options to consistence, however they vary from those utilized as a part of the private division. The part additionally builds up the dispatching prerequisites in its last segment C408.
Choice #1 – ASHRAE Compliance
On the off chance that a working in New York City meets the prerequisites of ASHRAE 90.1-2013, it naturally consents to the NYC Energy Code. The total name of ASHRAE 90.1-2013 is Energy Standard for Buildings Except Low-Rise Residential Buildings.
Alternative #2 – Prescriptive Compliance Path
With this approach, the building must completely agree to areas C402 through C405. Segment C406 likewise applies for business spaces, and Section C406.1.1 for inhabitant spaces.
Segment C402 – Building envelope prerequisites, covering angles, for example, protection, sun powered warmth pick up, fenestration and air spillage.
Segment C403 – Building mechanical frameworks, for example, warming, cooling and ventilation hardware, and their separate controls.
Segment C404 – Service water warming
Segment C405 – Electrical power and lighting frameworks, covering angles, for example, lighting controls, inhabitance sensors, transformers, engines, and general vitality utilization necessities.
Segment C406 – Additional vitality proficiency choices. This area sets up a rundown of additional vitality productivity prerequisites, and business structures must agree to no less than one of them. These additional prerequisites center on territories like HVAC, lighting and sustainable power source.
