Energy and Carbon Footprint Reducing Technology

> Variable Speed Drives
A variable speed drive can reduce energy consumption by as much as 60%. For a 90 kW motor in continuous duty, this can mean over £9,000 per year. This is because the variable speed drive reduces the amount of energy drawn by the motor.

Even a small reduction in speed can give significant savings. For instance, a centrifugal pump or fan running at 80% speed consumes only half of the energy compared to one running at full speed.

> High Efficiency Lighting and Control
Considerable savings can be made by upgrading existing lighting schemes to High Efficiency luminiares and/or installation of automatic control.

> Metering
Part L applies to new and existing buildings other than dwellings. The requirements are intended to provide a breakdown of energy consumption by different end-use categories - lighting, heating, ventilation, pumps and fans etc. - so that building owners and occupiers can reduce their energy use by 5-10% or more. To achieve this it is suggested that at least 90% of the annual energy consumption should be accounted for.

The Regulations call for separate metering for final distribution boards greater than 50kW. So the regulations effectively call for metering at most final distribution boards and even where this is not required, it would be good practice. Furthermore, if a board supplies lighting and small power, these loads should be metered separately.

The Regulations also call for separate metering of motor control centres feeding pumps and fan loads greater than 10kW. Meanwhile individual metering is required for boiler installations greater than 50kW, chiller installations greater than 20kW and electric humidifiers greater than 10kW.
