One World Trade Center already stands for resilience, renewal and the future of Lower Manhattan. As New York raises the bar for building emissions, the tower can make the next chapter visible: renewable electricity generated directly from one of the city’s defining glass façades.
Local Law 97 is pushing New York’s large-building sector toward much lower emissions, with stricter limits from 2030. One WTC can lead by example: make distributed renewable generation visible on the building that already represents New York’s capacity to reinvent itself.
Qualified roof and façade surfaces are screened against the same energy and commercial assumptions used throughout this case study.
Grid-equivalent CO₂ is modelled using the local grid factor. Actual market-based emissions impact depends on the building’s electricity procurement and renewable-energy contracts.
See how electricity generation and equivalent energy cost change through the year as solar resource, orientation and shading shift.
The southwest, south, southeast, west and east façades all make meaningful contributions. The result is a genuine envelope resource whose output migrates around the tower through the day.
The model spreads generation across the tower’s faceted south, east and west-facing envelope. That diversity suits an iconic building where no single flat façade defines the architecture.
Solar Studio reveals the energy potential hidden across an entire building envelope — not just the roof. It combines advanced 3D solar simulation with the commercial metrics asset owners need to make a decision.
We recreate the building and its urban surroundings so the analysis reflects the real geometry of the façade, roof and neighbouring skyline.
Advanced ray-tracing follows sunlight through every hour of the day and every season of the year, revealing how solar access changes across the envelope.
Nearby towers, setbacks and the building itself are captured in a detailed shading profile, separating consistently productive surfaces from those that spend too much time in shadow.
We translate the solar opportunity into generation, energy savings, carbon reduction and payback — turning a complex façade into a clear investment picture.
See where the building can generate, when that energy arrives, and which surfaces create the strongest commercial value.
These inputs define the One World Trade Center case study and can be changed for a building-specific assessment.
Indicative feasibility assessment. Results support early-stage decision making and should be followed by site, structural, electrical and façade-engineering review before project development.
We can turn this model into a site-specific pilot scope — target surfaces, expected generation, integration pathway and indicative economics.
