Just six months after installation, public sector buildings using Voltalis are already seeing clear, measurable results. From reduced electricity bills to lower carbon emissions, the data shows that smart energy management and demand response can deliver fast and effective outcomes, and real energy savings – without disruption or changes to daily behaviour.
At the University of Wales Trinity Saint David, the results speak for themselves.
13% energy savings in less than six months
Since Voltalis was installed in more than 100 student accommodation rooms, the university has recorded a 13% reduction in electricity use. These energy savings began immediately, with no changes required to how rooms were heated or managed.
Since the end of November 2024, the system supported the electricity grid over 5,000 times and, more importantly, there were no complaints from end users. Voltalis operated silently in the background, maintaining comfort while actively reducing both electricity consumption and emissions.
“Since installing the Voltalis solution, we’ve achieved a 13% reduction in electricity use across our student accommodation – all without any changes in comfort or behaviour. That’s rare, especially in a heritage university with complex infrastructure. What’s even more impressive is that despite the system running consistently, there were no complaints from users. Everything worked quietly and seamlessly in the background.”
— Daniel Priddy, Head of Sustainability
Smart tech that works in heritage settings
The university’s buildings include protected and heritage sites – often difficult to retrofit with modern energy systems. Voltalis offered a smart, non-invasive solution that worked directly with existing electric radiators. No major works, no rewiring, no downtime.
This case proves that even the most traditional or complex buildings can embrace smart energy technology quickly and effectively and reap the benefits from day one.
What this means for the wider public sector
Across the UK, there are more than 140,000 public sector buildings, including hospitals, schools, and offices. Many rely on older electric heating systems that are expensive to run and difficult to upgrade.
Voltalis provides a scalable, low-risk way to reduce, emissions, and cost while increasing energy savings. Key advantages include:
- No capital cost – Installation and operation are completely free
- Minimal disruption – Existing heating systems stay in place
- Instant results – Savings begin as soon as the system goes live
- Aligned with government targets – Supports both local and national decarbonisation strategies
Smarter decarbonisation for public infrastructure
Voltalis uses demand response technology to reduce electricity consumption at peak times. These brief, automatic adjustments help ease pressure on the grid, reduce the need for fossil fuel generation, and cut carbon emissions at the source – all while preserving comfort and performance.
Voltalis is now live with 1.5 million smart thermostats in over 250,000 homes and public buildings, providing meaningful savings at scale and helping to build a more resilient and sustainable energy system across Europe.
