developments in lamp technology to ensure that our systems continue to be compatible,’ says Churchill.


Portsmouth City Council has chosen to invest in a lighting control system from Ex-Or for its head quarters, which has reduced its lighting bill by an estimated £39,000 a year. This has been achieved by the automatic elimination of the unnecessary use of its office lighting. The energy saving being made has also enabled Portsmouth City Council to cut its carbon footprint and make a serious contribution to its Carbon Reduction Commitment obligations.


The council has cut its annual energy consumption for lighting in the offices and corridors before the Ex-Or installation from 1,259,398 KWh to 655,211 KWh. This represents annual cost savings of approx £39,151 and annual CO2 savings of 326 tonnes. Within the 31,679 m2 glass-fronted civic offices on Guildhall Square, built in the 1970s, more than 1,500 staff are at work across its seven floors. Before the Ex-Or installation, the lights were on for much longer than the core 9am to 5pm working day.


Portsmouth City Council electrical services manager Jamie Cake said lighting controls were needed that would ensure light was delivered only where and when it was required. After a competitive tender, the council chose Ex-Or, part of Honeywell, to supply Gold Series LightSpot detectors for installation throughout the open plan office areas. LightSpot Standard Series detectors were also supplied to control the lighting in corridors and lift lobbies. These discrete, flush-fitting units control the lighting by both presence detection and photocell control. The microwave Gold LightSpot detector provides 360O movement detection capability. When occupants are detected, LightSpot ensures the lights remain on until such time as the monitored area is vacated. It then automatically switches the lights off. Integral photocells monitor levels of natural light, ensuring the lights only


come on when natural light levels are low.


Focus SB’s Home Automated Lighting System (HAL) has impressed an electrical contractor so much, that he installed it in his own home. Lee Bullen, managing director of LJB Contracts, Rickmansworth, has been sourcing his lighting control plates and electrical accessories from Adrian Storr at AT&T, Brentford, for about 10 years. He was shown the HAL system and was instantly impressed: ‘I was very keen to know more when I first saw it, so much so I have since installed 11 control plates in my house.’


The system Bullen installed mainly comprises HAL 4-600 packs with a mix of Horizon control plates that are all finished in satin stainless steel. He continues: ‘My house is 95 per cent complete and I could not be happier with the HAL system. Now when my teenage daughter goes out or to bed, she can press one button and lights in the whole house turn off – it’s going to save me a fortune!’ Focus SB’s Home Automated Lighting System (HAL) was introduced at the beginning of 2009 in response to demand for an easy to use, simple to install and fully integrated lighting control

device. ‘HAL’s modular design enables it to be expanded from a simple switching and dimming operation, to a control system that can operate all lighting circuits within a building,’ explains Roger Kemp, managing director of Focus SB. ‘The system can also be operated and programmed using the infrared handset, allowing four or more scene buttons to set lighting ‘moods’.’ Kemp says automated lighting control systems continue to be a fashionable addition to many residential and commercial properties. ‘They provide a far more stylish and easier to operate alternative to rotary dimmer switches and offer potential energy savings that traditional products may not. Optional infra-red remote controls also give an enhanced ease of use and convenience.’
