Already
On-site solar is already part of the building.
GuocoLand’s 2025 sustainability reporting says solar panels at Guoco Tower generate electricity for common-area lighting, alongside recent chiller and AHU optimisation.

Guoco Tower.
The roof proved the case. The façade is the next available surface.
Guoco Tower already uses rooftop solar to power common-area lighting and has continued to optimise its chillers and air-handling systems. The proposition is simple: they already believe in on-site generation. Sydsol gives them somewhere new to put it.
Read the building
You already use rooftop solar. Now unlock the vertical surface.
GuocoLand already operates solar PV at the tower and continues to invest in energy efficiency. Sydsol gives that proven on-site generation strategy room to grow: once the roof is finite, the façade becomes the next controllable solar surface.

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
North and west are the expansion surfaces.
The north façade is the largest modelled contributor, west is second, and the roof remains important. West-facing output also carries generation later in the day, extending the existing roof-solar profile.

Where the electricity comes from
The model is a true extension of the existing roof strategy: roof generation remains meaningful, while north and west façades unlock substantially more area.

Scale what already works
The roof was step one. The façade is the scale-up.
GuocoLand already operates solar PV at the tower and continues to invest in energy efficiency. Sydsol gives that proven on-site generation strategy room to grow: once the roof is finite, the façade becomes the next controllable solar surface.

Next standard
Use the vertical envelope to scale the same strategy.
Façade solar turns limited roof area into a larger building-scale resource without requiring a new site or remote project.
Proof of adoption
The organisation already operates PV here.
That removes a major behavioural hurdle: the technology category is understood and accepted.
Efficiency first
Recent HVAC optimisation reduces demand.
Generation then becomes the complementary supply-side layer rather than a substitute for efficiency.
Solar Studio result
North and west are the expansion surfaces.
North is the largest modelled contributor, west is second and the roof remains material. The model shows where the next increment of on-site solar could come from.

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.

Assumptions & inputsOpen to review the model settings
Indicative feasibility assessment. Results support early-stage decision making and should be followed by site, structural, electrical and façade-engineering review before project development.
