BMSi, part of British Gas Business, is responsible for energy management and buildings management systems at Terminal 4, as well as other projects at Terminals 1, 2 and 3, Stansted, and a number of other locations. Increase in air traffic placed additional pressures on Terminal 4's infrastructure and existing technologies meant there was room for improvement in energy usage.

In 2004, BMSi put together a proposal outlining ways of saving energy, resulting in a series of highly successful projects. Predictions of £103,000 savings a year were eclipsed with actual savings of £136,000 per year. CO2 savings also came in at 33% above forecast, and HV readings showed a monthly improvement of 37%. Impressively, the project had been achieved at a relatively low cost, requiring no major financial investment. As a result, the team has been awarded the responsibility for Terminal 5 as well.
