SPECIFIC is working with the Active Building Centre to retrofit a building on Swansea University‘s Bay Campus with integrated renewable energy technologies and a smart energy control system.
The two-storey modular building, known as ‘Y Twyni,’ is used for teaching and is home to the Students’ Union. It will be fitted with 135kWp of solar photovoltaics, a large scale electrical energy storage system, and EV charging capabilities. A control system will manage the energy generated by the solar panels and distribute it between the energy storage system, car chargers, and the adjacent School of Management building. A solar PV carport with space for five vehicles will also form part of the energy system.
These integrated renewable technologies will help Y Twyni to save money and carbon emissions, enable investigation of control and use strategies for battery storage, and help the university reach its net zero carbon target by 2040. The energy generated by the solar panels can be stored in the batteries and released when needed. Depending on the cost and carbon intensiveness of grid power at different times of the day, the control system will decide when to draw energy from the grid and when to use the renewable energy generated by the building.
Y Twyni will be our most comprehensive retrofit to date, with greater solar generation and battery storage capacity than any previous projects. Its extensive sub-circuit metering will allow monitoring of the energy performance of the building itself and its integration within the campus system.
The project is funded by the Active Building Centre, with SPECIFIC supporting the design process and advising on energy systems and controls. It is scheduled for completion by the end of July this year.
