Building Regulations Part L2
To enable building owners or occupiers to measure their actual energy consumption, the Building Regulation Part L2 Section 3.3 - 3.6 details the requirements for metering of a building's energy consumption. It is stated that a "reasonable provision would be to enable at least 90% of the estimated annual energy consumption of each fuel to be accounted for". For electricity, this "reasonable provision" would include installing energy meters:

      incoming to every building and each separate tenanted area above 500m2

Additional meters would thereafter be required such that the following can be directly measured or reliably estimated:

      on any process load that is to be discounted from the building's energy
        consumption when comparing measured consumption against published
        benchmarks
      on plant items consuming input powers equal or greater to those shown in the         table below:

Plant item Rated input power (kW)
Boiler installations comprising one or more boilers or CHP plant feeding a common distribution circuit 50
Chiller installations comprising one or more chiller units feeding a common distribution circuit 20
Electric humidifiers 10
Motor control centres providing power to fans and pumps 10
Final electrical distribution boards 50

We can provide energy meters for panel or DIN-rail mounting. For supplies up to 120 amps, direct connect meters are available to considerably reduce installation costs by removing the necessity for external current transformers, voltage protection devices and additional cabling.

In addition we can also supply, install and commission software based energy monitoring systems capable of reading data from new meters and existing pulse output energy meters. These energy monitoring systems can present information for secure viewing by multiple users requiring only standard web browser software.
