Energy Efficiency

A1 Lighting Magazine take a look at some of the products available that ‘tick all the right boxes’ for energy efficiency.


Its everywhere we look - ‘energy efficiency’ is imprinted on our minds. With emphasis on Part L1 building regulations, energy efficiency and cost savings, installers look for products that help meet these requirements. Click Scolmore’s latest development combines a 5.5W LED Reflector lamp from the Energetic low energy range, with the GU318 fire rated downlighter from its award-winning FlameGuard system. This solution is low energy, Part L compliant and offers built-in protection against fire and noise pollution. Each fitting is fire rated to 30, 60 and 90 minutes, and fully airflow and acoustically tested. Harvard Engineering have installed their


new premises with their own solutions; products that save energy, keep electricity bills to a minimum, and reduce CO2 emissions. DALI LED drivers from Harvard’s CoolLED range are installed throughout. Harvard’s DALI drivers deliver efficient, high performance dimming control for high-brightness LEDs. The LED drivers provide dimming capabilities across a range of output currents, maximising efficiency, using intelligent digital programming to alter lighting levels at set times in all areas of the


22


premises. Motion activated, the drivers also turn the lights off if a room is empty, meaning no energy is wasted. The California Academy of Sciences in


San Francisco have adopted an impressive lighting scheme designed by Arup’s lighting designers, using Sill Lighting’s range of 003 metal halide projectors. The high power projectors, installed above the glass ‘bolla’ housing the Rainforest exhibit, provide lighting that supplements daylight entering through skylights of the outer living roof. Positioned in the space between the concrete roof and the 90-foot diameter glass dome, they illuminate through the glass onto the rainforest canopy, with its spiraling path leading visitors through the rainforest experience. Arup specified 140 one and two kilowatt


003 series high power projectors from Sill, designed for the Osram HQI-TS lamp. The


light source has a high Photosynthetic Active Radiation (PAR) efficiency, making them closest to daylight. The high wattage fixtures are installed outside the glass dome surrounding the Living Forest, keeping the temperature of the tree canopies below 100°F, providing a comfortable environment for butterflies in the exhibit. The fixtures have been arranged in clusters at the crossover of the roof beam with the power supply arranged over two circuits. Arup


completed extensive research and testing, ensuring the best optic


control, minimising spill light and glare,


whilst maximising visibility and comfort. The scheme aims


to reduce energy consumption, using a fixed light dosage of 240 klux/hr, delivered over an extended illumination period at a lower target light level. This innovative approach lowered lighting capital costs and
