Philips has been chosen as the LED lighting supplier for the Zero Energy House project.

National Renewable Energy Labs (NREL) in the United States defines a zero energy building as “a residential or commercial building with greatly reduced energy needs through efficiency gains such that the balance of energy needs can be supplied with renewable technologies”.

The Zero Energy House, owned by Auckland couple Jo Woods and Shay Brazier, is being built in Pt Chevalier, Auckland, using careful design and solar power. Zero Energy means that, over the course of a year, the house will generate as much energy as Shay and Jo will use.

At times they will generate more energy than they need, and will use a grid connection to sell this surplus energy back to their electricity company.

Jo and Shay chose Philips lighting products for the house because the extensive range of Philips Light Emitting Diodes (LEDs) met all of their lighting design requirements.

The lighting for the house has been designed so that each area is lit according to its specific needs, which means that the right amount of light is delivered to make each area work as it should.

The targeted lighting design strategy also meant that the number of energy efficient lights and the power of these lights was carefully considered, reducing the cost of installing the lights in the house and the ongoing cost to operate them.

The lighting is a mix of Philips LED bulbs, SmartBright LED downlights, and Ledino LED fittings. All of the light bulbs in the house are from the Philips Master LED range, which come in a variety of types to suit different fittings, and provide long lifetimes of around 25,000 and 40,000 hours.

The 18 SmartBright LED downlights in the house last up to 15 years, and use integrated LEDs in an all-in-one design which eliminates the need for bulb replacement. Three stylish Ledino wall lights have also been installed with an expected lifetime of 20 years.

The LED bulbs used throughout the house consume around 80% less energy than incandescent bulbs, and can last up to five times longer than compact fluorescent bulbs.
