CLIENT ENERGY MANAGEMENT BRITISH LAND
2008/09 baseline, saving 47.4 million kWh, 24,500 tonnes of carbon and £3.3m on occupiers’ energy bills.
Land share British Land can only be successful in its energy-reduction initiatives by working in partnership with its building occupiers. The developer uses green building groups, with occupiers and building management teams, to provide a forum to agree energy-saving initiatives and monitor progress, with roles and responsibilities formalised through Green Memoranda of Understanding. British Land provides office occupiers
with building environmental statements every six months. It believes that this is unique in the sector in providing detailed, year-on-year building management and occupier performance comparisons. It offers to fund energy reviews where occupiers are committed to energy reductions. These reviews will highlight initiatives occupiers can implement to drive energy reductions. There have also been improvements to
the reporting and transparency of energy invoicing. In July 2011, all multi-let office occupiers received an energy statement for each whole building, detailing the basis for allocation of costs to each occupier and identifying total costs of energy by occupier. ‘The information provided through our
new monitoring system and optimisation process is also providing the basis for much better collaboration with occupiers and building management teams. At our green building group meetings, we are able to focus much more on results than we ever could in the past,’ adds Snoxall.
All change on the Euston Road and Broadgate
At 338 Euston Road at London’s Regent’s Place, British Land achieved £35,000 of energy savings this year, with 17% lower base-build energy use than last year and 2% less energy use by occupiers in their areas. This follows a recent refurbishment of the building and upgrades to equipment, including: nNew water heaters, so that the main boiler system can be switched off during the summer
nMore energy efficient air handling units nUpgrades to the building management system to enable more sophisticated programming for heating and cooling
nImprovements to the lighting system, with more energy-efficient lamps and motion sensors.

British Land expects to achieve further energy reductions going forward, following the implementation of the Edge optimisation process.
The green building group at 10 Exchange Square at London’s Broadgate has been particularly successful this year, with £82,000 of energy savings cutting carbon emissions by around 500 tonnes.
Occupiers achieved a 17% reduction in their areas and British Land cut base-build energy use by 17%. Initiatives included carrying out overnight lighting surveys, installing motion sensors, and deactivating override buttons on air handling units, with occupiers’ facilities managers now arranging when plant needs to be run out-of-hours.
What next? Subject to the energy monitoring system achieving its projected reductions in base- building energy in the these buildings, British Land plans to roll it out across more of its office buildings and shopping centres in the UK and Europe, with occupier agreement. ‘We believe that, within three years,
further energy reductions will require capital investment, and behavioural change by occupiers,’ says Snoxall. ‘We are therefore undertaking detailed base- building energy and water reviews to highlight energy-saving opportunities via capital investment. We will continue our efforts to lead on energy efficiency to cut costs for our occupiers, at the same time as reducing carbon emissions.’ It seems that British Land has the Edge. CJ
