Climate-based daylight analysis of fixed shading devices in an open-plan office

Assessment of Noise Effect on Employee Comfort in an Open-Plan Office: Validation of an Assessment Questionnaire

Background: Today, open-plan offices are among the most common work environments. Although the noise in these environments is usually below the standard level, it is one of the critical annoyance factors due to the nature of the mental work. Accordingly, this study aimed to assess noise effects on employee comfort and validate the Persian version of the assessment of noise effects on employee c...

Indoor climate in an open plan office: a comparison between measurements and CFD simulations

This paper presents the results of experimental measurements and computational fluid dynamics (CFD) simulations of the indoor environment of an open-plan office. The measurements were conducted in the Indoor Environment Research Facility (IERF) at IRC/NRC, in which six mock-up were setup to simulate an interior open-plan office. Two scenarios were investigated: isothermal and non-isothermal. Th...

Perception of Water-Based Masking Sounds—Long-Term Experiment in an Open-Plan Office

A certain level of masking sound is necessary to control the disturbance caused by speech sounds in open-plan offices. The sound is usually provided with evenly distributed loudspeakers. Pseudo-random noise is often used as a source of artificial sound masking (PRMS). A recent laboratory experiment suggested that water-based masking sound (WBMS) could be more favorable than PRMS. The purpose of...

Static and Dynamic Daylight Control Systems: Shading Devices and Electrochromic Windows

This paper analyses the office demand connected to the use of different dynamic window and lighting control systems with the aim to optimize their usage aspects and characteristics from both visual and energy efficiency viewpoints. The approach is based on an improvement of the non-commercial hourly simulation program IENUS. Results are referred to a typical office located in Mediterranean clim...
