Empire State Realty Trust's (ESRT) goal is to achieve net-zero carbon emissions across its 10.1 million square foot portfolio by 2035 (more on ESRT's Sustainability program here).  Learn more about how ESRT evaluated the technical and economic potential to achieve carbon neutrality at five of their buildings, including the Empire State Building.

Reflections
  • Central systems may present more opportunities for optimization based on automation and controls sequences.

  • High performance standards: Consistent rollout of high-performance standards is crucial:
    • Key internal and external service providers (fit out designers, controls vendors, maintenance contractors, lease negotiators) require technical oversight to ensure all their work supports energy and carbon efficiency goals.
  • Tenant designs: Small deviations of tenant designs from energy code and tenant design guidelines can build up to significant impediments to achieving carbon savings.
  • Small decisions add up to big impact: Consider long-term ROI and operational consequences of first-cost decisions on all projects.
