Energy efficiency
15 flights worth of carbon to save
Four thousand commercial and public sector buildings could save up to £10 million collectively by being more efficient according to EDF Energy Solutions sector manager of energy solutions Steve Beer
these systems – and those responsible for them – are therefore on the front line of any efficiency drive. The focus on energy efficiency is increasingly motivated not only by the desire to save money on energy bills, but also to reduce carbon emissions in an effort to transition towards a low carbon economy.

At EDF Energy we are working with thousands of our customers to help them identify the
opportunities they have to improve their energy
cknolweging heating and ventilation systems as among the biggest energy consumers in most commercial buildings, Mr Beer says
efficiency.We recently analysed energy consumption at over 4,000 commercial and public sector sites – including offices, schools and hospitals – to identify the significant impact that simple changes make. We found that these organisations could
collectively save over £10 million a year through retr ofitting Enhanced Ventilation Controls, using more efficient air conditioning systems, and through optimising their heating and ventilation schedule. These changes to HVAC systems could see each building reduce their carbon footprint by 29 tonnes each year on average, equivalent to the carbon impact of 15 flights from London to Sydney.
What we have consistently found is that there remains a large opportunity for greater efficiency in HVAC: over 60% of the organisations we analysed could make significant savings through optimising their schedule.
This might involve looking again at real time energy consumption data to understand when and where heating and ventilation are being used, and where this can be reduced or shifted. Many
professionals working in this space may feel that the low-hanging fruit is already gone, but our research suggests there are still many opportunities to make a big difference through simple changes.
