‘The right’ classroom lighting boosts learning by 20%
The correct type of lighting can significantly improve children’s learning, especially if it is natural light, research shows. Full spectrum lighting, including sunlight and artificial lighting that replicated natural light, is known to improve behaviour, reduce anxiety and boost health. In turn, these improvements translate to a marked improvement in learning. According to a study by the California Energy Commission, classrooms that receive a high level of daylight offer students a 20% better learning rate in maths and 26% in reading, compared with classrooms that received little natural light. Bruce Cantrill, Head of Marketing and Business Development for power and lighting specialists CMD, said: “The days of ‘one size fits all’ fluorescent lighting in schools are rapidly becoming a thing of the past. Innovations in dynamic lighting technology now mean that natural daylight can easily be replicated to create a much more positive learning environment for both pupils and staff.” Dynamic lighting — lighting that can be adjusted remotely to suit particular lessons and activities — can further support and enhance classroom learning, suggests a recent study published in the journal Optics Express. In contrast, poor lighting reduces how effectively the brain can collect information. Research by Dr. Ellen Mannel Grangaard of the University of Nevada suggests that overhead cool white fluorescent lighting can be detrimental to learning for a number of reasons, including aggravating hyperactivity and promoting off-task behaviour such as fidgeting, daydreaming and talking in lessons. The glare — or veiling reflection — created when fluorescent lighting reflects off paper and white boards also physically hinders student’s ability to read properly and can result in disengagement with the lesson. Mr Cantrill adds: “Another great benefit of dynamic lighting in schools is that teachers are able to remotely optimise their environment by controlling the brightness and lighting temperature in their classroom on a light-by-light basis. This can be adjusted throughout the day to suit both the nature of the lesson and the amount of natural daylight available.” www.cmd-ltd.com/products/audacy-wireless-lighting-controls-by-cmd/
LED lighting for schools – a bursar’s guide
According to the Carbon Trust, getting lighting right is essential for both energy efficiency and the bank balance of a school, and as importantly for the wellbeing of its occupants. In the third of this special series of lighting in education guides, Energys will explore how LED upgrades can create multiple financial opportunities. It can also improve site health and safety, maintenance, and deliver infrastructure gains for bursars. Many bursars know the basics; energy efficient LEDs save on bills and the environment. But, the right level and the best quality of light is crucial to alertness, accuracy and the overall enjoyment of those working and learning in schools too. And, LED retrofit technologies can minimise work on school estates, and hike up other gains on the ledger too. Energy and cost savings Overall, The Carbon Trust says UK schools could reduce energy costs by around £44 million per year which would prevent 625,000 tonnes of CO2 from entering the atmosphere. Lighting, says the Trust, represents 20% of school’s energy costs, and 8% of their energy use. ‘Currently LED upgrades use at least 80% less electricity than an equivalent tungsten halogen source,’ it continues. So, the energy and cost-saving potential for bursars and their schools is clear. Further, ‘A properly engineered LED light has a comparatively long life, typically in the order of 50,000 hours. This can reduce maintenance costs significantly depending on the light source they are replacing,’ the Trust reveals. The Trust says making the business case for such low energy lighting is quite straightforward in terms of electricity saved vs investment required. Calculating the potential savings is based on identifying: a) The current lighting load (Watts or kiloWatts). b) The hours of use per annum. c) The new LED lighting load. d) The unit rate you pay for each kWh of electricity. “It is important to establish this cost-benefit analysis in schools nationwide,” says Kevin Cox, Managing Director, Energys. “When that analysis is done, the financial pathway to energy efficient, cost-saving installation is clear.” Health and safety (H&S) In schools, H&S is key. Today’s bursar’s aren’t just financiers, they are operations managers too. LED retrofit technologies are advantageous from this viewpoint. For a start, LED bulbs are more durable than traditional bulbs, and they have fewer fragile parts. Also, they are mercury free, compared with other bulbs which, if shattered during routine maintenance, require special care and removal, to say nothing of risk to operatives. Further, LED bulbs generate very little heat, so they can’t burn staff or children, and they make for a more comfortable teaching environment. Together, it all adds up to lowered H&S risk, and lower H&S costs. “We are right up to the minute on H&S,” says Cox. “We will install to the highest H&S standards and beyond, adding to the overall, lifetime H&S benefits LED offers to school bursars.” Funding options and capital expenditure For many bursars, even when the cash and environmental rationale stacks up, financing is still a key challenge. “It is wise to consider financing arrangements to suit your needs and more importantly, ensure you are saving money from the outset,” says Cox. “There are many schemes out there, and it’s crucial to research this intelligently and pick the right one. “Energys, in partnership with Utility Rentals and Smart Eco Energy, offers a financing scheme tailored to the needs of schools and colleges.” Such an approach is likely winto favour with boards of governors, tasked with myriad, competing demands for financing. And, you can also use your LED financing plan as evidence of the school’s cash-savvy, energy-intelligent approach in marketing materials and branding. Furthermore, LED lighting can even be included in schools’ lessons plans on sustainability, increasingly a key part of the curriculum. In so doing, another dual benefit arises, with further financial gains and teaching benefits. The shift to LED lighting Energys has a number of case studies on LED upgrades for schools and colleges available. These will help you learn more, and consider the best way to embed sustainable, futurist and beneficial lights in your environment.
