Metering & Sub Metering

Direct Efficiency have extensive experience assisting businesses with a variety of metering and sub metering projects. Sub metering systems can be complex and depending on the size and complexity of the business premises, a site visit may be required.

Our consultants can assist you with a complete range of metering services which involves project managing the installation of: 

Sub meters can be installed throughout commercial buildings to monitor the energy consumption of particular areas. The meters enable the collection of invaluable half-hourly data. Many of our current clients have sub meters installed to monitor energy consumption for the following supplies:

· Building HVAC (Heating Ventilation and Cooling) including Air Handing Units (AHU's) and Chillers.

· Plant room consumption

· Main Equipment Room (MER) supplies

· Tenanted floors

· Tenant retail units

· Lighting and power

By sub metering commercial and business premises it is possible to closely and accurately monitor energy consumption to identify the areas of highest consumption. 

he data from sub meters can be collected and, using a Monitoring and Targeting software package, it is possible to analyse the data to build an in-depth picture of a building’s energy use. The information from the sub metering system can be used to identify key energy drivers and highlight energy wastage.

Sub Meters for Multi-let Commercial Buildings

Sub meter systems can be installed to accurately monitor individual tenant's electrical consumption, whether they occupy an independent site, a retail unit, an entire floor of a building or even part of a floor within a commercial building. 

Tenant meters can be installed in multi-let offices and multi-occupancy buildings to help landlords to accurately reclaim utility costs from tenants. If the data from these meters is being used to bill the tenants, then Measuring Instruments Directive (MID) approved meters must be used.

Smart Meters and Automated Meter Reading (AMR)

Automated Meter Reads means no more manual reads. AMR can be installed for electric, water and gas to enable half-hourly data to be collected. 

A smart meter is an advanced utility meter ideal for smaller sites under the 100kW threshold for half-hourly meters.   A building that has over 100kW electrical load is always fitted with a half hourly capability tariff utility meter.

Temporary Portable Metering

Portable meters are very useful when you need to assess where and when your electricity is consumed, or to confirm that your existing meters are accurate. 

Portable meters can also be very useful should you wish to monitor energy consumption on a temporary basis in a specific area. Portable meters can be used to quantify the effect of implementing energy saving initiatives. The portable meters we use are non-intrusive and usually do not require supplies to be interrupted to allow installation and later removal.
