Daylight Harvesting: Maximizing energy efficiency

Daylight Harvesting: Maximizing energy efficiency

Daylight harvesting is the use of a control system, such as DALI control, to reduce the use of artificial lighting in building interiors when natural daylight is available. Studies have shown that, by using daylight harvesting technologies, owners can obtain average annual energy savings of 24 percent. Daylight harvesting should form part of an overall lighting control initiative, along with high efficiency lighting ballasts and luminaires, and pre-programmed lighting schedules.

Sub-metering: tracking performance indicators

Sub-metering: tracking performance indicators

Sub-metering is the installation of metering devices to measure energy consumption at specific points within a building. It is an effective way to understand energy consumption, recognise power quality issues, identify waste within a facility, and measure and track key performance indicators, such as watts per square metre, occupancy, total tenant load, common area costs and carbon footprint.

Balancing lux & watts

Lux vs. Watts

With the gradual phasing out of 50-watt halogen and incandescent lights over the next few years, business and commercial facility managers have begun to face the dilemma of finding a suitable replacement for the tried and tested 50-Watt halogen that falls in line with the Building Code of Australia’s new regulations of only 5-watts per square metre.

Low voltage halogen lamps will be banned from next year in Europe

Low voltage halogen lamps phase-out

Low-voltage halogen lamps are to begin to be banned from next year under draft legislation drawn up by the European Commission.

12V MR16 lamps are the workhorses of retail, commercial and, increasingly, residential lighting and millions are sold every year in the EU.

But under Ecodesign legislation, ‘poor performing’ versions are to be phased out from next year.

Better-performing versions, such as those with infra-red coatings, can remain until 2016.

New solid state LED lighting technologies - A case study in RMIT, Melbourne, Australia

New solid state LED lighting technologies

The Royal Melbourne Institute of Technology strives to continuously reduce its energy usage and is starting a number of immediate and long-term initiatives to cut energy consumption. As part of its efforts, RMIT University recently upgraded to energy-efficient LED lighting in Building 28’s Research Lounge, significantly its energy consumption and improving light quality.
