Balance Code Compliance With Comfort
NYC energy code requires continuous insulation, efficient HVAC, and LED lighting—but comfort comes from thoughtful detailing. Start with R-10–R-15 insulation at walls (rigid or spray foam) and R-10 under floors if feasible. Air-seal all penetrations before framing, then verify with a blower-door test if available. Choose variable-speed heat pumps or mini-splits with smart thermostats for even temperature control.
Lighting & Controls Under Code
All fixtures must be high-efficacy (LED) with dimming controls. Combine occupancy sensors in secondary zones (storage, bath) with manual overrides in living areas. Layer warm (2700K) and neutral (3500K) color temps for balance and visual depth—code allows both within efficiency limits.
Mechanical Efficiency & IAQ
Use ERVs with ECM motors for balanced ventilation that recovers energy from exhaust air. Insulate all ducts within conditioned space to R-6 or better, and seal joints to SMACNA standards. A ducted dehumidifier tied to the ERV ensures 45–50% RH for comfort and material stability.
Windows, Doors & Envelope
Upgrade basement egress windows to U ≤ 0.35 / SHGC ≤ 0.40 double glazing. Use insulated metal doors or thermally broken frames. Flash transitions to the foundation with compatible waterproof tapes for airtight integrity. A warm basement is a dry one—moisture and temperature comfort go hand-in-hand.
