Questionnaire on Methods & Tools Used for Lighting Retrofit of Buildings

As a way to analyze the workflows and needs in practical retrofitting processes, a questionnaire has been created in a web-based survey system.

The survey is directed to all actors involved in building retrofit processes. It focuses on practices regarding electric lighting and design strategies to increase daylight utilization. The survey’s results will be used to better understand the retrofit process, barriers, and needs.  The questionnaire is subdivided in the following four parts:

1. Role of lighting in retrofits
2. Design methods within the retrofitting process
3. Tools for lighting design
4. Background information for statistical purpose

The questionnaire is available in different languages and can be found via the Task 50 webpage on the SHC website or directly at: http://leso2.epfl.ch/task50/
