BT hopes to cut energy costs by 10% with new boiler technology
BT has rolled out a new 'intelligent boiler optimisation' across 246 sites on its estate, after a trial run at three locations netted energy savings between 8% and 13%.
The telecoms company paid £1.2m for 'M2G load optimisation control' technology, which prevents boiler dry cycling by differentiating between a genuine demand for heat from the building and a call for heat as a result of standing losses from the boiler.
All boilers will lose heat from their casing and the flue -known as standing losses. Boilers will often fire just to recover these standing losses even if there is no genuine heating demand from the building. This is known as "boiler dry cycling".
BT director of energy and carbon Richard Tarboton said: "BT continues to drive down its energy consumption and carbon emissions. Our varied estate presents us with a challenge requiring innovative solutions that can be deployed with minimum disruption."
The M2G solution, provided by Sabien Technology, reportedly delivers full payback within 2 years and can also cut carbons emissions by between 10% and 25%.
"The BT project is a great example of how M2G plays an important role alongside traditional building controls," said Sabien CEO Alan O'Brien. "We are delighted with this project, not just because of the level of savings achieved by M2G, but our capabilities of delivering a project across such a large estate."
Using information to help cut emissions and costs has been a recent focal point for BT, as back in July, chief sustainability officer Niall Dunne said the firm would be actively exploring how big data could help them.
