LIGHTING & LIGHTING CONTROLS FEATURE


MODULAR BUILDINGS AND LIGHTING CONTROLS ARE A CLASS ACT


As class sizes reach an all-time high and budgets keep shrinking, Martyn Frear, business development manager at CP Electronics, explains why modular buildings and lighting controls can ease the squeeze on schools and education


T


here were 66,000 more children in the nation's schools in June 2018,


compared to the same point in the year prior. The increase is undoubtedly influencing learning. A BBC Yorkshire investigation quoted 13 year old Silas Ennis saying that, “It's difficult to learn because there's so many people around you, so you're not focusing as much on the lesson.” The Department for Education last year


revealed statistics that the average secondary school class size is 21.2 pupils, up from 20.8 in 2017. The vast majority of classes are between one and 30 students, but there is also data that shows 11.5 per cent of students were in classes of 31-35, and 0.6 per cent were in classes with 36 students or more. Funds are clearly the issue. While


additional funding might not magically appear any time soon, there is the prospect that money, more classrooms and learning facilities can be made through a growing source: modular buildings and modular lighting controls.


GOING MODULAR Modular construction is not new. But, it has recently taken off, as more and more clients turn to it for quicker construction and real benefits in time and cost savings. Rather than having materials and


hundreds of staff on a construction site, sections of buildings are constructed off site in factories instead and then delivered for assembly and installation. This then mitigates traditional construction issues, such as delays in materials and poor weather, factors that ultimately produce higher costs. The real beauty though is that modular


construction is not just about the floors, walls and ceilings. Every part of a modular building needs to come together seamlessly in as quick a timeframe as possible; this includes the lighting controls. To this end, plug and play modular


lighting controls have been developed specifically for this purpose. These controls include the Vitesse Modular standard and dimming versions, which can adapt and grow from two-way to 16-way by simply


adding extender modules. The Vitesse Plus 7 can also be easily configured to take into account the complexity of classroom control requirements, with onboard programmes that feature 90 different configurations from a single standard LCM.


A DIFFERENT CLASS Designing lighting and lighting controls for educational buildings, particularly schools, is a different animal altogether when compared with sectors like healthcare and commercial. It is imperative that


contractors follow the guidance from The Chartered Institution of Building Services Engineers (CIBSE) and Education and Skills Funding Agency (ESFA). The latest guidance produced by ESFA


is outlined in its Output Specification 2017 document, which replaced the previous Facilities Output Specification. For electrical engineers particularly, Technical Annex 2E: Daylight and Electric Lighting is the guidance that should be adhered to. With schools, the functionality


requirements demanded for new projects, funded by ESFA, are varied and many. However, the common requirement is that lighting controls must now be automatic to all spaces in order to facilitate control of the visual environment and energy savings. Control devices are to be simple and intuitive too. Additionally, schools should make the


most use of natural daylight as much as possible, to increase energy savings. There are other considerations too,


dependent on the space in question. Balancing this performance criteria may seem tricky. However, modular lighting controls are designed to accommodate these demands. The Vitesse Modular can handle the


general area requirements and be specified in four-pole or six-pole connections for auto-on/off switching or dimming, and its plug and play design

In schools, the functionality requirements demanded for new projects are varied and many


ensures a quick, hassle-free installation. Meanwhile, the Vitesse Plus 7 with pre-


designed control schemes can accommodate more complex classroom requirements of graduated dimming in rows adjacent to windows and interactive whiteboard control.


A SINGLE SOURCE One of the biggest challenges of the construction market is that the supply chain is traditionally long and fragmented. With many suppliers, this can cause delays as information is sought and clarified, thus pushing up costs. To avoid unnecessary complexities, it is


always good practice to work with a single manufacturer where possible. This then ensures that systems can work together as intended - the manufacturer can advise on the best practice with its solutions, and installation and commissioning stages are pain free. Modular buildings can typically save


up to 30-50 per cent construction time over traditional bricks and mortar. As it continues in its popularity, it’s well worth engineers investing time in understanding how modular lighting controls work in tandem with this construction method.
