Post Occupancy Evaluation of Aquatic Ecosystem Research Laboratory Tan, Shen; Lei, Yi Zhong; Winardi, Alexander


This Post Occupancy Evaluation was performed as a requirement for the completion of MECH 550G/CIVL 598C. The purpose of this POE is to deliver a detailed report in order to provide UBC Campus Sustainability Initiatives with recommendations for improving the performance of the Aquatic Ecosystem Research Laboratory. Based on AERL’s trouble log history, we focused on evaluating the open-plan and private offices. The data collected consisted of measurements of the physical environment (thermal, acoustic, air quality, and lighting) at representative locations, a questionnaire administered to all occupants about satisfaction to current indoor environment, and monthly utility data supplied by the building owners. Physical and questionnaire data were collected in March, 2012. Key findings and recommendations are as follows: •Water consumption has always been above the design goal and MNECB baseline. •Energy consumption is below the MNECB baseline but further improvements are still needed to get closer to the design goal. Windows glazing can be replaced with ones that have higher R value. •The open-plan offices have excellent speech intelligibility but poor speech privacy. Furthermore, noises from the atrium propagate easily into the offices. Installing more acoustic baffles within the atrium and open-plan offices can minimize the discomfort. •The CO₂ level within the open-plan and private offices were well below the 1075 ppm limit set by ASHRAE 62 – 2007 •There is insufficient illumination within the open-plan offices. Higher wattage light bulbs or LED lights may be used on replace existing light bulbs. •The current control algorithm for space heating does not promote optimum heat transfer rate into the offices. Flow rate of hot water need to be controlled by automatic flow control valves instead of by manually controlled valves.
