In order to analyze workflows and needs in practical retrofitting processes, an online questionnaire was developed. 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 aim to contribute to the understanding of the retrofit process, barriers, and needs.
The questionnaire is subdivided into the following four parts:
1. The role of lighting in retrofits.
2. The design methods within the retrofitting process.
3. Tools for lighting design.
4. Background information for statistical purpose.
The questionnaire is open until the end of June, 2014 and available in several different languages. It can be found on:
