Heating & lighting efficiencies for London’s BSix Sixth Form College
project initiative to overhaul its lighting and boiler systems. Bob Herring, Premises Manager of BSix
L
College, explains that the desire to “reduce expenditure on energy and maintenance” was a primary driver of the upgrade. “We realised that with the latest boiler control and LED lighting systems we could achieve a dramatic reduction in our energy costs, as well as further minimising our carbon footprint and improving the environmental ambience of the college,” he says. The viability of such a large-scale
project was given a critical boost by the securing of energy efficient funding, via the Salix scheme, for at least part of the proposed upgrade. This was one of the areas in which lighting technology specialist Energys Group was able to provide assistance, having been appointed to the project after Herring received a recommendation regarding Energys’ similarly extensive programme of work at the nearby Hackney Community College. “We wanted to achieve a greener, more
carbon-efficient college, and thanks to the collaboration with Energys that has been possible – and all in a mere three weeks of work that was carried out in a way that had very minimal impact on the day-to-day activities of the school,” says

OCATED in the East London borough of Hackney, the BSix Sixth Form College recently undertook a multi-
Mr Herring. The lighting component of the project
was particularly extensive and involved the latest LED solutions from the Energys range. Down-lighters, hi-bay lights, tubes, flood lights, wall lights, emergency lights and more, were installed as part of an overhaul that included the upgrading of both lamps and fittings to the latest LED technology. In total, nearly 1,000 lights were modernised during a project that spanned classrooms, communal areas, corridors, staircases, the gym, the library, the car park and other primary spaces. The total value of the new lighting was
£83,830, but thanks to substantial projected annual cost savings of £19,731 the return on investment is expected to be achieved in just over four years. Rounding out the positive impact on the college and its activities, the headline statistics also included projected annual energy and CO2 savings of, respectively, 164425 kWh and 80.57 tonnes per year. “Movement sensors have also been
implemented in some areas of the school, further increasing our ability to use lighting only when and where it is required,” notes Mr Herring, adding that the overall end-result of the upgrade has been to “achieve much more consistent lighting across the campus”. The college has also called on Energys
for its boiler technology. Four of the company’s Dynamic Burner Management Unit (DBMU) Boiler Optimisers have been installed in the college’s plant rooms in a move that will improve the efficiency of the boilers without affecting the temperature of the building. Annual energy and cost savings of £3,258
and 155885 kWh, respectively, have been forecast, while the return period on the total investment of £6,960 is expected to be just 2.14 years. Significantly boosting the college’s ongoing carbon reduction initiatives, the CO2 saving resulting from the boiler optimisation exercise will be around 28.66 tonnes per year. The final primary component of the
project was the application of ‘valve- wrap’ insulation to internal heating pipes in multiple plant rooms. Another measure designed to minimise
heat-loss from the heating infrastructure, the valve-wrap project cost £8,400 and has a projected return on investment of just under five years. Annual cost and energy savings are expected to be in the region of £1,685 and 80622 kWh, while the college stands to reduce its carbon footprint by 14.84 tonnes per year as a result of this aspect of the project.
