Abstract

The consumption of energy for lighting in buildings depends very much on the way people interact with the build environment. In this study the following building types were studied, office, school, university, commercial and industry buildings. For each building type typical user groups were identified. Then, Personas have been created for each group. As opposed to describing users with numbers and statistics, a single Persona reflects a group and is presented with a narrative. The Persona has a name, a family and living conditions that are representative for the group, also her/his values and interests are not uncommon. The Personas “typical day” includes a time schedule typical for the group. Visual conditions are common for the group, but some specific challenges connected to the visual conditions that may occur in the group are also mentioned. Personas were created using one of the three methods: interview at the working or learning place, workshop at the working place, and internet survey which was used in the time of pandemic lock-down. Those methods are described in the chapter 2 Methodology and evaluated based on the authors experience, chapter 9 Conclusions. Chapters 3-7 presents Personas for the offices, schools, university buildings, commercial buildings, and industry buildings. In the chapter 8 Home office personas, student and professional, are presented. The report ends with the description of energy consumption calculation that applies Lumen method which is based on the use of a Coefficient of Utilization (CU). CU computes the fraction of lamp lumens that directly reach the workplane and the fraction from interreflections. The boundary conditions of use of the respective buildings, based on the results from literature review and interviews with users, are also presented, table 2.
