For more information on the building’s energy performance, see the DEC for this building.
Recommendations
| Recommendation | Potential impact on carbon emissions |
|---|---|
| Consider how building fabric air tightness could be improved, for example sealing, draught stripping and closing off unused ventilation openings, chimneys. | Medium |
| Consider fitting 24 hour/7 day time controls onto electric HWS cylinders. | Low |
| Review the air conditioning energy performance report and seek to implement any outstanding recommendations for action. | Medium |
| Recommendation | Potential impact on carbon emissions |
|---|---|
| Consider engaging experts to review the condition of the building fabric and propose measures to improve energy performance. This might include building pressure tests for air tightness and thermography tests for insulation continuity. | High |
| Recommendation | Potential impact on carbon emissions |
|---|---|
| Consider a small scale Tri-Generation system as an alternative to conventional separate boiler and chiller systems. | High |
| Recommendation | Potential impact on carbon emissions |
|---|---|
| Consider introducing a formal energy policy that demonstrates management commitment to reducing fuel consumption. This should include gaining building users’ commitment to save energy, allocating responsibility, setting and monitoring targets to ensure that they are met. | High |
| Engage expert to review the overall heating strategy and consider an investment programme to switching to alternative solutions that would be more energy efficient. | High |
| Consider upgrading the current BEMS incorporating enhanced metering and monitoring systems that provide early warning of operational inefficiencies. Dynamic monitoring turns live data into a series of prioritised actions and summarises financial savings that could be achieved. | High |
| Ensure the boiler controls & timers for the boilers are monitored, working correctly and have the optimum settings. Check that the correct SET points have been applied. | Medium |
| Engage experts to review the building lighting strategies and propose alterations and/or upgrades to the luminaries and their control systems and an implementation plan. Current recommendation is to upgrade all remaining lighting that have not already been upgraded to LEDs (with PIRs where appropriate). This is especially important for the GU10s, CFL, 2Ds, T8s and T12 still present in the building. The T5s can be upgraded to LEDs as and when they start to fail. | High |
| Ensure that all radiators have TRVs installed and have their usage monitored to make certain that the correct settings are applied. If possible, after the system has been balanced, try to prevent the valves from being adjusted. | Medium |
| As appropriate, ensure that all computers and screens have power save settings enabled during the daytime and are switched off over night and not left on stand-by. All televisions should be switched off when not in use rather than being left on stand-by. This could be achieved by incorporating automated equipment. Switches to sockets with "on" lights should be turned off if there is nothing plugged in and being used. | Medium |
| Ensure that employees are made aware of bad practices that can lead to excessive energy wastage. For example, having the heating or air conditioning on while the windows are left open. | Medium |
| Engage experts to survey the air conditioning systems and propose suitable alternatives that would improve the effectiveness and efficiency. | Medium |
