This project consists of three parts of tasks: (1) investigating the indoor air quality of the major public domains; (2) setting up the verification system for indoor air quality portable instruments; (3) setting up the self-management and amendment system. The outcome is abbreviated as follow:
1. Investigating the indoor air quality of the major public domains
(1) The standard procedure of IAQ inspection was established and applied to 100 major public domains. The public domains were classified into 10 categories and were visited for collection of basic data and the encouragement of their participation of EPA’s self-management activities.
(2) The standard procedure of IAQ monitoring was also established and applied to 50 major public domains. Our experiences on the investigation and monitoring gave the following aspects of recommendations:
a. The priority of IAQ species control for each category of public domains.
b. The feasibility of portable instruments used as the surrogate of standard methods.
c. Searching the cost-saving monitoring procedure by comparison of the current monitoring procedure with that adopted in the last year.
2. Setting up the verification system for indoor air quality portable instruments
(1) Referring to the EPA’s “Management Guideline of Indoor Air Quality Monitoring Instrument”, this project have set up the verification system for indoor air quality portable instruments, including the principles, methodologies and procedures for various portable instruments. The method of verification is to test portable instruments using standard span gas and then to determine the allowable standards for each parameters.
(2) We collected 23 portable instruments of 9 categories and verified them using the above methods. The results showed that for all portable instruments we collected the formaldehyde and ozone could not pass the allowable standards.
(3) The collected 23 portable instruments were also tested in the ‘Environmental Simulation Chamber’, which is able to set up various humidity and temperature, and applied to the realistic public domains, monitoring the indoor air quality with the ‘standard methods’ in the same period. Comparing the monitoring results from portable instruments and standard methods, we found that the differences were significant for formaldehyde, ozone, TVOC, PM10 and PM2.5. If the results of the standard methods were served as the comparative basis, the deviation of this five species did not pass the allowable standards.
(4) An ‘workshop of the verification system for indoor air quality portable instruments’ was held for the agents of monitoring instruments and commercial laboratories to demonstrate the verification system and the allowable standards of this project.
3. Setting up the self-management and amendment system
(1) We collected the foreign self-management documents and analyzed their impacts to our country in five aspects : management, scope, efficiency, training, classification.
(2) Using real data to quantify the cost of self-management, which were divided into three parts: employment cost of IAQ inspector, training cost of IAQ inspector and cost of IAQ monitoring.
(3) We collected the IAQ treatment and improvement technologies, classifying them as two categories of ‘source control’ and ‘ventilation dilution’, and access their applicability in the future.
(4) Two public domains were selected to conduct IAQ improvement engineering. The engineering feasibility is accounted for the types of targets, improvement of air quality and benefits of the improvement.
(5) An ‘workshop of the IAQ self-management and amendment system’ were held for people concerning IAQ. The IAQ improvement engineering of two cases in this project is demonstrated for the benefits. The participants are encouraged to join the EPA’s activities of self-management.
