Inneklimat i kontorslokaler : Fallstudie av belysning och ventilation i kontor i Västerås

Sammanfattning: The office environment is an important part of the workers’ performance and need therefore to be designed in a pleasant and functional way. The problem is not that today’s offices do not function but rather that these need to be improved to achieve better work results. Lighting and ventilation are big parts of the office environment. In this project will three offices be examined, and these are Archus, WSP and Sweco. Purpose: This study is done to find improvement measures for these three offices based on the examination of the light and ventilation conditions. The improvements that will be suggested are mainly based on a survey but also a study on how these two factors affect the employees’ performances. Method: To perform this project was a literature study, a case study and measurement of illuminance used. A survey om how the employees experience the office environment were also conducted. Drawings provided by the office managers were used to perform calculations of the airflow. Results: The survey shows that 73.5 percent of the 68 people who answered the survey feel comfortable in the current design of the offices. The rest feel that they lack privacy and a quiet environment. In addition, 82.4 percent are happy with the lighting situation and 69.1 percent with the air quality. Archus, WSP and Sweco all meet the required guidelines set for illuminance in an office with certain deficiency. For ventilation do Archus and Sweco meet the minimum requirements for airflow, but there are small differences between the dimensioned airflow and the minimum requirement for WSP. Conclusions: The conclusion of this study is that the three studied offices lack seclusion which affects the office workers’ ability to work. The current lighting, and the ventilation in smaller rooms also contribute worsened working conditions. Good lighting conditions is required to achieve good work results. The same applies to ventilation where the air flow is deficient in certain rooms and should be regulated.
