Using daylight – it’s only natural
Preliminary findings on the potential for natural daylight to illuminate commercial buildings have been released from the BRANZ Building Energy End-use Study (BEES), and it’s not all sunshine.
Flickering lamps - from beeswax to gas
The need for improved lighting led to many interesting inventions, from safety matches to chandeliers. Fortunately we no longer have to kill a muttonbird or a whale to have oil for our lamps!
Electric lamps
Electric lamps promised much that the flickering flame could not. They were to be cooler, brighter, steadier and more pleasant to the eye without releasing toxic, noxious or dirty by-products. However, they did not start that way.
Aiding the visually impaired
Whether at home or out in public, visually impaired people have specific accessibility requirements that are different to those with physical disabilities. Thoughtful design and new technology can help.
Green schools are smart schools
The evidence is in. Children work better and are healthier when their schools have good lighting, clean air and are neither too hot nor too cold.
Downlights, wet areas and insulation
The choice of downlight fittings cannot be left to the owner, particularly in wet areas or those that form part of the thermal envelope. The type of downlight must be specified when a building consent is applied for.
Tucking up downlights
Manufacturers, suppliers, designers, electricians and insulation installers should all know how to maintain the thermal envelope around downlights. Do you?
Good for business
An international report finds that healthy workplaces may result in higher productivity. Some of its results mirror work done by BEES on indoor air comfort and the use of natural light.
Feeling sick from LED lighting?
Early fluorescent lights gave some people nasty headaches. Recent research on the adverse effects from artificial lighting found that not all leds produce quality light – flicker from some causes similar issues.
