IEA-SHC Task 50: Advanced Lighting Solutions for Retrofitting Buildings

Retrofitting of non-residential buildings with energy efficient daylight and artificial lighting solutions can significantly contribute to reductions in electric energy consumption. However, appropriate technologies have to be made available to the stakeholders (investors, industry, consultants, designer) that are involved in the retrofitting process. Thus, system solutions for daylighting and artificial lighting were evaluated, simple rating and evaluation tools were developed and case studies that serve as best practice examples were monitored. The results were collected in the Lighting Retrofit Advisor, which helps stakeholders within the lighting retrofit process.
