Offices

Office energy bills are largely made up of heating, ventilation and cooling, lighting and office equipment. If you’re looking to cut your office energy bills, here are a number of solutions to consider.

Below we have calculated the top five actions that will enable an office to cut its energy bills and reduce carbon emissions by up to 30%.

What offices can do to reduce carbon emissions by up to 30%

  • Install solar panels
  • Replace lighting with LEDs and maximise natural light
  • Prioritise energy efficiency when replacing monitors, appliances and IT equipment
  • Install electric vehicle charge points
  • Adopt and embed energy reduction targets and behaviours.

Examples

Refurbishment of office building cuts energy bills by £60k

Premier House is a multi-tenanted 3,800 square metre office in Twickenham refurbished by the Low Carbon Workplace, a property development partnership between sustainability experts the Carbon Trust, asset manager Columbia Threadneedle and developer Stanhope. Before its refurbishment the building had inefficient heating, cooling and ventilation systems, single-glazed windows, a leaky façade and an E-rated Energy Performance Certificate.

Premier House has now been totally refurbished to radically improve its energy efficiency. Measures included: enhancing insulation to walls and ceilings; improving air tightness; installing a new ventilation system that recovered 85% of energy from extracted air; window replacement; fitting low energy lights; and the use of daylight controls and occupancy detection on lights. The refurbishment reduced energy consumption in the building by 64%, cut energy bills by £60,000 a year and delivered a return on investment of 18%. Find out more.

LED lighting to save over 100 tonnes of CO2

Electricity North West has a range of lighting systems that vary in age and efficiency at its eight non-operational sites with lighting accounting for between 20-50% of the overall energy use at each site.

We have therefore chosen to install LED lighting at all of these sites to reduce energy consumption and costs. Investment costs will be reduced by economies of scale. It is anticipated that the investment of £360,000 will be paid back in just over five years and will save 107.62 tonnes CO2e every year. Find out more.
