Australia 108.
A supertall home has very little roof per resident. The façade is the shared energy asset.

Australia 108 brings 1,105 homes into one vertical community. Instead of asking hundreds of residents to share a comparatively tiny roof, Sydsol turns the much larger common façade into a shared clean-energy asset.

Read the building

Solar for homes without rooftops.

Detached homes can put solar on a roof controlled by one owner. In a supertall residential building, hundreds of households share a comparatively tiny roof. Sydsol changes the surface available to the community: from one roof to an entire vertical envelope.

What the building envelope could deliver

Qualified roof and façade surfaces are screened against the same energy and commercial assumptions used throughout this case study.

— Annual generation
— Annual energy value
— Modelled payback
— Grid-equivalent CO₂
— Installed solar area
— 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

Two façade bands do most of the work.

Northeast and northwest surfaces dominate the modelled annual output, while the roof is a much smaller contributor. For a supertall apartment building, the important resource is not the roof above 1,105 homes — it is the vertical common property wrapped around them.

Height creates the surface area the roof cannot.

Where the electricity comes from

Northeast and northwest façades are the main modelled generation surfaces. The distribution reinforces the residential proposition: unlock shared vertical area rather than treating rooftop space as the only renewable-energy option.

Vertical community

The next solar suburb could be vertical.

Detached homes can put solar on a roof controlled by one owner. In a supertall residential building, hundreds of households share a comparatively tiny roof. Sydsol changes the surface available to the community: from one roof to an entire vertical envelope.

Already

The building concentrates 1,105 homes into one 319-metre structure.

Australia 108 is one of Melbourne’s defining residential towers, with common amenities, lifts, pools and shared services that create persistent building-level electricity demand.

Next standard

Make common property productive.

Victoria’s 2026 parliamentary inquiry explicitly identified façade solar as one of the options that can expand renewable access for apartment residents. A productive envelope gives the owners corporation a larger shared generation surface than the roof alone.

Shared infrastructure

Give residents a shared solar asset.

Common-area generation can support shared loads and create a renewable-energy asset owned collectively — a practical way for apartment living to participate in Australia’s solar transition.

Visible amenity

Sustainability becomes part of the address.

Australia 108 already sells height, views and landmark identity. A productive façade can make energy performance part of that same premium-building proposition.

Solar Studio result

Two façade bands do most of the work.

Northeast and northwest surfaces provide roughly three quarters of the modelled annual generation; the roof is secondary. The geometry itself explains why a high-rise needs a vertical strategy.

The Solar Studio advantage

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.

01

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.

02

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.

03

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.

04

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.
