Tackling climate change
We refurbished and remodelled the existing 1930s structure to increase the energy efficiency of the building.
Improved insulation was installed, as well as new double glazed windows designed with UV shading, to help maintain the internal temperature of the building, as well as reduce glare. The windows are controlled through a traffic light system, which informs users when to open or close them to maintain the correct indoor temperature.
The building is linked to the nearby hydroelectric power station which can generate approximately 1.3millon kWh of electricity per year - this is the equivalent to supplying enough green electricity for over 300 average households. Any surplus power will be sold into the national grid. The hydroelectric power station has been designed to have no detrimental effects to the wildlife within the river. A fish pass has been incorporated to increase the number of fish species, eventually improving the aquatic biodiversity.
As well as the hydroelectric power, solar photovoltaic (PV) panels are used to supply the building with renewable energy.
The temperature regulation of the building is controlled by a new river water cooling scheme. Cold river water passes through pipes into the basement plant room which provides cooling via a heat exchanger. Water is returned to the River Derwent, a maximum of three degrees Celsius warmer.
At night, an adiabatic cooling system operates by spraying fine mist into the building. As the mist evaporates, it consumes heat energy, both cooling and rehydrating the air. This cooler air improves efficiency and cost by reducing the need for additional cooling.
