Transforming a historic campus with smart energy solutions
The University of Wales Trinity Saint David
The University of Wales Trinity Saint David (UWTSD) in Lampeter boasts a historic campus that blends tradition with modern sustainability efforts, making it an ideal setting for innovative energy solutions.
In collaboration with UWTSD, Voltalis implemented its energy-saving technology across 100+ student accommodation rooms, on their Lampeter campus, the home of the oldest degree awarding institution in Wales, seamlessly integrating with existing electric radiators. This approach supports UWTSD’s sustainability goals whilst aligning with Welsh Government carbon reduction targets, without the need for costly infrastructure changes.
“We’ve installed Voltalis in over 100 rooms, and we’re set to see the benefits over the new term: with energy bills going down, decarbonisation goals progressing and the integration working seamlessly with our other sustainability efforts and wider energy mix reduction. We love mixing new tech like Voltalis with more traditional energy
efficiency initiatives like solar panel installation or even using local sheep wool for insulation in our roofs.”
“If you can do it on a campus like this, you can do it anywhere.”
“The University has buildings that are 200 years old, with much more modern buildings added in the past decade. The challenge is always how to decarbonise both effectively - especially with the Welsh Government’s ambitious and pioneering carbon reduction targets. Voltalis has been brilliant and we’re proud to be an early installer within the United Kingdom. The benefit of this technology is that it clips onto our existing electric radiators
– there’s no need to replace existing systems, just wire in and go.”
“What we like about Voltalis is that it effectively makes old traditional radiators smart without replacing the radiator system. People think installing smart tech is long, complicated and expensive. But this isn’t the case with Voltalis. If you can do it on a campus like this, you can do it anywhere.”
