The Department for Transport has introduced a number of measures across its organisations to improve energy efficiency and reduce energy costs. These include:-
- An overarching Operations Sustainability Strategy which enables the identification, management and delivery of energy efficiency measures;
- The development and implementation of the Carbon Trust endorsed organisation specific Carbon Management Plans by the Central Department and the Driver and Vehicle Standards Agency (former Driving Standards Agency estate);
- Rationalisation of offices to maximise the efficient and effective use of office space;
- Relocation of staff to more appropriate sites where functions have diminished or changed;
- Partial closing of buildings during low occupancy periods (i.e. Christmas, New Year);
- Optimising Building Management Systems to minimise the use of heating and cooling;
- Installation of boiler optimisation controls to improve boiler efficiency;
- Installation of voltage optimisation equipment at large administrative buildings to reduce electricity consumption;
- Lighting improvement programmes (including the installation of LED lights where appropriate and Passive Infrared (PIR) controls);
- Optimisation of IT servers;
- Improvements to building insulation;
- Updating desktop IT with more efficient models;
- Rationalisation of peripheral IT equipment such as printers and faxes with the introduction of Multi-Functional Devices (MFDs);
- Installation of renewable energy sources such as wind turbines, air source heat pumps and photovoltaic cells where appropriate and cost effective;
- Motorway lighting switch off scheme between Midnight and 5AM in pre-assessed areas of the motorway network.
The Department for Transport is committed to achieving all its sustainability targets and lowering energy costs through improving energy efficiency is seen as a key element in attaining that goal.
