This presentation describes the general building renovation design with an emphasis on acoustic comfort and indoor air quality for the open-plan office space and collaborative meeting areas. Acoustic comfort metrics: reverberation time, spatial distraction distance and sound transmission loss will be compared to illustrate the impact of surface absorption, white noise and interior partition design. The method and results for evaluation of indoor air quality will be discussed. Thermal comfort measurements in accordance with ASHRAE Standard 55 will presented for individual workstations. The thermal comfort results will be compared with the unique IEQ Toolbox™ method for single day measurements.
