NEW LIGHTING SOLUTION is the crowning glory at ‘royal’ school
A new lighting control solution from automation specialists B.E.G is delivering energy efficiency to the Royal Hospital School in Suffolk
E
stablished by a Royal Charter in 1715, the Royal Hospital School was formed
as a means to educate the sons of seafarers. Moving into the 21st Century, German manufacturer, B.E.G has provided the school with potential energy savings of up to 80% via the installation of lighting occupancy sensors. The school is the largest boarding school in East Anglia, with around 700 pupils between the ages of 11 and 18. With this in mind the school’s board of directors was keen to find a solution that would reduce its energy consumption and carbon emissions. After an extensive lighting site survey
by B.E.G., the Royal Hospital School has replaced its conventional switches with more than 50 of the company’s Luxomat two channel occupancy sensors. Installing the Luxomat means the occupancy detector switches on light, heating and ventilation only when required. The sensor is a motion detector designed specifically for ceiling mounting and its optical system has a coverage angle of 360°. It is high resolution and is well suited for a school environment where most of the activity in a classroom, for example, occurs when pupils are sitting down.
SENSING ARTIFICIAL LIGHT In addition to movement, the presence detector also senses daylight and artificial light and controls the overall
brightness. If this is higher than the required luminous intensity, the artificial lighting is turned off again even though movement is present. It is then switched on if not enough daylight is available. The artificial light can also be re-
adjusted to the amount that is needed to meet the pre-determined brightness level. The Royal Hospital School will also save money on maintenance costs as the Luxomat is remote controllable. B.E.G. supplied the Royal Hospital School with the sensors via Ipswich- based MDE Electrical Supplies - one of the German company’s stockist partners in the UK. The Luxomat was installed in the school’s classrooms, changing rooms, corridors and several other
New CLH high power driver
Harvard Engineering, manufacturer of lighting solutions, has launched the first in a range of high power drivers specifically designed for ease of use in street lighting applications. The CLH Single Channel driver offers up to 200W of power with simple resistive programmable drive current. The product can be programmed across a number of different current ranges, which means customers can standardise on a single compact driver, reducing inventory and associated carrying costs. High efficiency was also a focus in the design. The driver design was completed to be compliant with all
90%+ efficiency industry standards. It’s flexible 120-277V universal input offers 91% efficiency at 120V and 93% at 277V, with 6kV surge protection. WiMAC compatibility comes as standard, making the CLH a well suited driver to be used alongside Harvard’s LeafNut wireless monitoring and control system for street lighting. Although designed for the street lighting market, the driver is also well suited for all applications requiring a
high power driver. An IP66 rated version is also available, providing protection in wet environments. Harvard Engineering

circulation areas The school expects to see a return on
its investment within just one year. The occupancy sensors will be further rolled-out to other areas of the school including the pupils’ dormitories during the summer.
REGAL HISTORY Located in the village of Holbrook near Ipswich on the banks of the River Stour in the Suffolk countryside, the Royal Hospital School has strong naval traditions and connections with the British Royal Family. The then future King George VI laid the foundation stone at Holbrook when he was the Duke of

York in 1928 and HRH Prince Andrew has been a regular visitor to the school since 1992. Paul Jones, B.E.G. UK director,
commented, “B.E.G. is delighted to have met the lighting control requirements of such a prestigious school as the Royal Hospital School that is steeped in history with a long association with both the Royal Navy and the British Royal Family. “The school stands to make significant
savings in energy consumption thanks to the installation of the Luxomat in key circulation areas of the school. The occupancy sensors will enable the Royal Hospital School to become a more energy efficient school, while allowing it to reduce its carbon footprint at the same time.”
