Chapter 3. A Review of Energy Saving Potential and Strategies for Electric Lighting in Future Low Energy Office Buildings

Dubois, Marie-Claude LU (2013) In Energy: Modern energy storage, conversion, and transmission in the 21st century
Abstract
This chapter presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review outlines that an energy intensity of around 10 kWh/m2yr is a realistic target for electric lighting in future low energy office buildings, based on theoretical calculations, measurements in full-scale rooms and simulations with validated lighting programs. This target would yield a significant reduction in energy intensity of at least 50% compared to the actual average electricity use for lighting in offices. Strategies for reducing energy use for electric lighting are also discussed, which include: improvements... (More)
This chapter presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review outlines that an energy intensity of around 10 kWh/m2yr is a realistic target for electric lighting in future low energy office buildings, based on theoretical calculations, measurements in full-scale rooms and simulations with validated lighting programs. This target would yield a significant reduction in energy intensity of at least 50% compared to the actual average electricity use for lighting in offices. Strategies for reducing energy use for electric lighting are also discussed, which include: improvements in lamp, ballast and luminaire technology, use of task/ambient lighting, improvement in maintenance factor, application efficacy and spectral quality of light sources, reduction of maintained illuminance levels and total switch-on time, use of manual dimming, and switch-off occupancy sensors. Strategies based on daylight utilization are also presented and the relevant aspects such as effects of latitude, window characteristics, properties of shading devices, reflectance of inner surfaces, ceiling and partition height are discussed.
