How our intelligent design helps keep consumption down

Energy Efficiency

By working in partnership with industry leading contractors who have their own strong and ambitious social values.

By maximising renewable energy sourcing and seeking innovate ways to improve energy use.

By using the latest BIM and smart technology to drive waste reduction and energy efficiencies, from construction through to day-to-day operations.

By installing electric and cycle charging stations to encourage longer distance carbon free travel.

We aim to save nearly 2 million litres of water every year by using recycled shower and basin water to flush our toilets.

We aim to achieve a 33% reduction in water consumption per annum by installing specialist ‘low flow’ taps, which reduce water volume throughout the building.

Heat pumps connect to our cooling towers to use heat rejected from the building to generate hot water and heating.

By designing the building’s façades in such a way as to reduce solar gain and reduce the energy required to cool internal air.

By using highly efficient fan coil units throughout the building to minimise the demand on power.

By installing LED sensor lighting throughout the building and in turn reducing energy use.

Reduced reliance on fossil fuels with 60% of heating and hot water demand being provided by electric heat pumps.

We aim to avoid localised flooding through the use of sustainable drainage of rainwater through collection in tanks.
