Saint Andrew's is the oldest cathedral in Australia. It was founded in 1817 when Francis Greenway led the design of a building known as the Metropolitan Church. This neo-Gothic cathedral was completed in 1868 and consecrated on St. Andrew's Day of the same year. During the canopy renovation in the cathedral's chapter house, a photovoltaic skylight was installed, proving that tradition and modernity can merge in perfect harmony while maintaining a high aesthetic level.

The BIPV modules were installed on the courtyard between the cathedral and the adjacent chapter house building. The photovoltaic material used, semi-transparent amorphous silicon, creates a uniform surface where the technology is not perceived.

The BIPV system produces about 3300 kWh of electricity per year. The electricity is mainly used for the air cooling system.

The BIPV system is made up of glass modules with a thin inner film of amorphous silicon inside with a low degree of transparency. The modules were custom-made to adapt perfectly to the Chapter House Canopy structure. The 70 m2 photovoltaic skylight helps shade the entire courtyard below by filtering solar radiation.

The system installed is estimated to prevent the release of 65 tonnes of CO2 into the atmosphere over 35 years, equivalent to using 57 barrels of oil per square metre. The return of investment time was calculated at less than ten years.
