Already
Renewable-powered district.
100% of electricity supplied across Azabudai Hills comes from renewable sources. The district achieved LEED ND Platinum; Mori JP Tower achieved LEED BD+C Platinum in 2025 and WELL Core Platinum in 2024.

Azabudai Hills already set the renewable-powered standard. The next standard is renewable-generating architecture.
Azabudai Hills already operates on 100% renewable electricity, while Mori JP Tower holds LEED BD+C Platinum and WELL Core Platinum. Sydsol can make the next chapter visible in the architecture itself: a landmark tower that not only uses renewable electricity, but generates it through its envelope.
Read the building
From a renewable-powered district to a renewable-generating district.
Azabudai Hills already combines renewable electricity, district energy, water reuse, wellness and top-tier certification. Mori is also increasing the share of renewable power it generates itself. Sydsol brings that ambition onto the tower: the architecture becomes part of the district’s energy infrastructure.

Project LCOE
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.
Energy & economics
Monthly electricity & LCOE
See how electricity generation and equivalent energy cost change through the year as solar resource, orientation and shading shift.
Monthly electricity & LCOE
Generation through the day
The southern envelope is the generation zone.
The corrected Solar Studio model concentrates output on the sun-facing sides: southwest contributes about 40% of annual generation, southeast about 24%, and the roof about 15%. The case is strongest when the highest-value surfaces are treated as a targeted architectural layer.

Where the electricity comes from
Southwest and southeast are the dominant modelled surfaces. The opportunity is concentrated enough to support a selective intervention rather than covering the tower indiscriminately.

Next standard
Renewable-generating district.
Instead of another procurement claim, the tower itself becomes part of the energy system — a visible, on-site generation layer on one of Japan’s most advanced urban developments.
Mori’s own direction
More in-house renewable generation.
Mori Building says it has begun developing its own solar generation facilities and intends to increase the share of in-house renewable power supplied to its properties.
Urban philosophy
“Create Cities, Nurture Cities.”
The strongest fit is city-making: the envelope becomes infrastructure inside a district already designed around integrated energy, wellness and resilience.
Solar Studio result
The southern envelope is the generation zone.
The corrected model places about 40% of annual generation on the southwest façade and another 24% on the southeast. This is a selective south-facing opportunity, not blanket coverage.

The Solar Studio advantage
We model the building.
We model the building.
Then we follow the sun.
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.
Advanced 3D building model
We recreate the building and its urban surroundings so the analysis reflects the real geometry of the façade, roof and neighbouring skyline.
Sunlight, tracked all year
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.
A true shading profile
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.
From solar potential to business case
We translate the solar opportunity into generation, energy savings, carbon reduction and payback — turning a complex façade into a clear investment picture.
Beyond rooftop solar
See where the building can generate, when that energy arrives, and which surfaces create the strongest commercial value.

Indicative feasibility assessment. Results support early-stage decision making and should be followed by site, structural, electrical and façade-engineering review before project development.
