ENERGY MANAGEMENT
to be integrated into the building automation system.
The first step in any metering strategy is to consider all energy that is imported or exported: main incoming supplies and renewables. The second step is to identify all sub-main circuits requiring meters: ie for end users, tenants and various activity areas. The third step is to provide metering that enables consumption loads to be identified in all key categories, such as: heating, hot water; lighting; small power; ventilation, pumps etc.
Specifiers also need to be aware of the EU Measuring Instruments Directive (MID) for any meter to be used in conjunction with the re-sale of electricity. This legislation became effective on 30th October 2006, with a 10-year transition period, and replaces Ofgem’s Schedule 7 of the Electricity Act 1989. Any new meter to be used directly for billing must be MID-approved after October 2016.
STAR CITY ENTERTAINMENT
COMPLEX An example where Carlo Gavazzi has brought all of this technology together would be Birmingham’s Star City mega leisure and entertainment complex. A network of MID-certified energy meters and a Dupline® bus- based lighting control system helps tenants save energy as well as costs.
With around 36,400m² of leisure space and 2400 secure parking spaces, Star City is one of the largest leisure complexes in the UK, comprising one of Europe’s biggest cinemas, the largest indoor adventure golf complex in England, a 22-lane bowling alley, all-weather 5-a-side football centre, open- plan gym, Laser Station and family climbing centre. It attracts 3.5 million visitors per year.
It is a multi-tenant site on a grand scale, so it’s vital that each tenant is billed accurately for their energy usage. The current network of EM21 energy meters provides three-phase energy metering across the site.

According to the Building Research Establishment (BRE), controls are the easiest and most cost- effective solution for saving energy in buildings. Clients and building occupiers, however, have failed to exploit advanced control solutions, says the BRE, because many of the innovative technologies they employ are perceived to be overly technical and complex to operate. This, when coupled with a lack of information on the subject, has resulted in a poor
uptake of control technologies and a subsequent failure to significantly reduce the carbon footprint of buildings and to provide a better environment for occupants.
Simple two-wire bus solutions such as Carlo Gavazzi’s Dupline® system offer a cost-effective means of improving the poor take-up identified by the BRE, tackling energy reduction and improving occupant comfort.
