National Trust Makes Switch to Energy Efficient Lighting

摘要

The National Trust, in collaboration with Philips Lighting, has recently achieved impressive energy savings in its lighting by replacing all the tungsten lamps in some 300 of its properties with various types of energy-saving light sources. As part of its 'Big Switch' initiative, the National Trust is committed to replacing all the older energy-inefficient lamps in its historic buildings.rnThe conversion process began more than 18 months ago with initial trials at the National Trust's properties of Polesden Lacey and Sissinghurst, among others. Since then some 100 sites have been surveyed and recommendations for new energy-saving lighting solutions adopted.
