Design, Applications & System Issues
Awards in European Design Competition (IAEEL 1-2/00)
Rethinking Light Levels (IAEEL 1/98) The recommended illuminance level is but one of many parameters that the lighting designer has to take into account when designing a lighting installation.
A Delightful Opportunity (IAEEL 1/98) Guest author Jane Palmer write about the savings that can be done in domestic lighting by installing energy-efficient compact fluorscent lamps.
Models and Meters Make the Difference (IAEEL 2/97) Detailed modeling and metering revealed how far off previous estimates of UK residential energy use had been.
Holistic Lighting Design for Tasks and Buildings (IAEEL 2/97)Guest authors David Loe and Paul Davidson sum up their holistic view on energy and cost-consious lighting design.
Occupancy Sensors for the Home (IAEEL 2/97) Occupancy sensors - or presence detectors - offer good options for minimizing energy use in residential lighting applications.
Guiding Light Efficient at Times (IAEEL 1/97) Hollow light guides remain an interesting niche application for distributing light from artificial light sources.
T5 Lamps Boost Fluorescent Lighting Efficiency (IAEEL 1/97) New T5 fluorescent lamps in combination with super-reflective aluminium could increase the efficacy of luminaires for fluorescent lamps by more than 30%.
The Efficiency of a Recent HLG Installation (IAEEL 1/97) A recent installation can be found in the post office terminal in Sundsvall, Sweden
A Brief History of Light Guides (IAEEL 1/97)
Halogen Uplights And Hot Ceilings (IAEEL 4/96) Halogen uplights, or torchieres, have rapidly become one of the most popular residential luminaires in the world. Not only has their energy use erased all of the savings achieved by compact fluorescent lamps in many countries, but their high operating temperatures have also caused dozens of fires in the US alone.
Flexible metal-halide uplighter for offices (IAEEL 4/96) Metal-halide lamps represent an area where recent developments have increased their potential for efficient office applications.
Give People Control Of Lighting Controls (IAEEL 3/96) Automatic lighting controls - with suitable manual overrides - offer major opportunities for improving performance, occupant satisfaction, and energy efficiency.
Advanced Lighting Controls Testbed in San Francisco (IAEEL 3/96)
They Turn Off the Lights (IAEEL 3/96) Wisely applied, occupancy sensors can achieve large savings by making sure that lights are turned off in unoccupied rooms.
Large-Scale Procurement of Occupancy Sensors (IAEEL 3/96) In Sweden, Nutek is coordinating some of Sweden's major commercial building owners in a technology procurement process involving 20.000 occupancy sensors.
Will Sensors Pay? (IAEEL 3/96)
Effects on Lamp Life (IAEEL 3/96)
Successful Retrofit (IAEEL 2/96) Successful retrofit of existing traditional lanterns in central London.
Students Delight in Daylight (IAEEL 2/96) Educators in North Carolina are learning a valuable lesson on the benefits of daylight in their schools.
Windows As Luminaires (IAEEL 3-4/95) Recent advances in technology have helped to make the window an ally in efforts to save lighting energy. Properly managed, the new window technologies can help minimize unwanted solar gains in summer as well as heat losses in winter, without squandering valuable daylight.
Words for Windows (IAEEL 3-4/95)
Lighting Design Software: Not Yet Good Enough (IAEEL 1/95) None of the PC-based lighting design software programs available today meet all the needs of demanding users, but the future looks promising.
Dedicated CFL Fixtures Bring Savings Home (IAEEL 1/95) Even though screw-based compact fluorescent lamps represent a large residential savings potential, much of these savings have not been realized. Dedicated pin-based CFL fixtures for the home are one answer to the challenge.
Dutch fixture-action (IAEEL 1/95) With the world's highest penetration rate for integral CFLs, the Netherlands is moving on to promote residential dedicated CFL fixtures.
HVAC Savings? (Lighitng--HVAC Interactions) (IAEEL 4/94) Do lighting retrofits also help save heating, ventilation, and cooling (HVAC) energy? This is a much-debated issue, and the answeris a complex one.
Daylight Savings: Not an Easy Catch (IAEEL 4/94) Guest author David B Floyd writes about lessons learned from the field commissioning of a daylight-dimming fluorescent lighting system.
A Systems Approach To Remote Light Sources (IAEEL 4/94) However promising the new, efficient light sources, such as the sulfur lamp, may be, they will be of little use if not coupled with systems that can distribute the light efficiently over large areas.
A Neglected Opportunity (IAEEL 2/94) The map is not the territory. Actual and predicted lighting energy savings can differ significantly. One solution is commissioning-to check that the systems are installed and operated as intended.
Loggers Give the Answer (IAEEL 2/94) Lighting loggers answer questions about when and how often individual luminaires are used. And since they don't require hard-wire installation, they provide these data at a low cost.
