Case Study: A Controlled Ventilation Solution for Laboratories at The Department of Natural Science of Tallinn University of Technology

This case study deals with the renovation project of ventilation system in the Natural Science Building of Tallinn University of Technology, covering the established aims and principles of technical solutions, in general, and results of monitoring. The reconstruction project involved the task of creating a new ventilation system for required indoor climate of laboratories, avoiding dissemination of harmful materials to rooms. In addition, it was required to keep the operations costs approximately at an acceptable level.
There are two separate central supply-exhaust air ventilation systems for general air exchange and for local ventilation systems. To assess the operating systems and to achieve the established aims, special testing of joint work between fume cupboards and main ventilation was conducted, using airflow smoke to emphasize the effect.
Results of monitoring demonstrate that investments for these ventilation systems were justified and the installed ventilation systems corresponded to our technical and sanitary-hygienic expectations.
