HSBC is investing £16m in a bid to halve carbon emissions from heating and cooling in its 800 UK branches.

This could equate to operational cost savings of £2.2m a year, based upon branches revamped in 2007.

Working with Mitsubishi Electric, HSBC has identified three areas which can improve the environmental performance of its heating and cooling systems: replacement of equipment, heat recovery and advanced control systems.

Any equipment over five years old will be replaced with modern systems which can adapt their power consumption to meet loads.

In addition, Mitsubishi Electric’s Lossnay heat recovery equipment captures energy from heat being expelled out of a building and transfers it to incoming air.

Finally, Mitsubishi’s web-based G50 controller allows HSBC to monitor the air conditioning unit at every branch so that overall energy consumption, and peaks in consumption, can be analysed.

When Mitsubishi Electric upgraded the heating and cooling equipment at HSBC’s Fleet Street branch, these were the results:

  • Running costs fell from £41.08 per day to £19.38 a day, a saving of £21.65 a day.
  • CO2 production fell from 187.31kg a day to 88.59kg a day, a 52.71% saving.
