IEA SHC Task 50

Subtask of the joint project “Energetic and ergonomic optimization of new lighting systems for renovated and new buildings”

Aim of IEA-SHC Task 50, led by Fraunhofer IBP: The International Energy Agency’s program “Advanced Lighting Solutions for Retrofitting Buildings” aims at supporting the retrofitting of lighting systems (daylight technology, electric lighting and lighting management) in non-residential buildings using innovative but practical approaches that can be applied to a wide range of buildings.

The work was coordinated in four subtasks: Subtask A: Market and Policies, Subtask B: Daylighting and Electric Lighting Solutions, Subtask C: Methods and Tools and Subtask D: Case Studies. There was also a joint working group responsible for networking activities and results.

Outcome

Within the framework of the IEA SHC project Task 50, a large number of reports and publications were issued. Among other things, the following results were obtained: Report on the market situation in the field of retrofitting lighting systems, handbook (sourcebook) on technologies for retrofitting daylighting and artificial lighting systems and documentation of prior completed projects and case studies on retrofitting lighting systems. With the “Lighting Retrofit Adviser”, Fraunhofer IBP has developed an electronic, interactive sourcebook with tips and recommendations, decision-making instruments and planning tools for retrofitting lighting systems. In the twenty case studies examined in detail, lighting energy requirements were cut by approximately 50%.
