Provisorisk takbelysning vid byggarbetsplatser : En studie av belysningens funktion och dess påverkan på yrkesarbetaren

Sammanfattning: This report explores the definitions of general- and work lighting in an indoor construction site and how the lighting affects a construction worker. This in order to clarify the controversial topic of: which purpose the ceiling lighting has, thus making the lighting plan optimal. This study was made in cooperation with Skanska Sweden AB. The main ceiling lighting-device in Skanska Sweden is a custom made LED-lamp which is the main tool that this research is based on. The main research methods are project site visits, interviews and surveys in combination with literature studies, and also practical measurements and simulations of the LED-lamps. The results of the interviews and surveys show that comprehension of the functions of the ceiling lighting varies among Skanska Sweden employees. While construction workers generally refer to work lighting when addressing ceiling lighting, the managers tend to refer to general lighting or as a tool to orientate the building. Although, how general lighting is defined, varies among the employees. With that said, the simulations reveal that a reasonable amount of a ceiling lighting will not fulfil the requirements for work lighting for all construction operations. Furthermore, our results from the interviews and surveys confirm those from previous studies; that lighting is essential for the well-being of people. A poorly illuminated workspace dulls one’s work performance and effects one’s health in both the short- and long terms. A well-lit workspace can, on the other hand, reduce the potential health and safety risks on a construction site and also ease multiple work tasks. There are currently no clear assembling routines of ceiling lighting. Therefore, to create consensus on the purpose of lighting and the health and safety prospects that come with it, this report recommends possible solutions and clarifications of the issues and misinterpretations in the matter.
