INVESTIGATION OF VOLATILE ORGANIC COMPOUNDS IN THE INDOOR AIR OF A SCHOOL OVER A ONE YEAR PERIOD FOLLOWING REFURBISHMENT

摘要

The air quality in an Infant and Nursery school in England was investigated over a 12 month period following refurbishment. The original school buildings were constructed in the 1970s and were closed for refurbishment in 2001. Prior to re-occupation, BRE undertook an indoor air quality survey involving the measurement of volatile organic compounds (VOCs), aldehydes and combustion gases. After the school re-opened in September 2003 the diffusive samplers were used to measure VOCs and aldehydes in all staffoffices, teaching areas and the main hall over a full school year. In addition the staffwere provided with questionnaires to record any symptoms that may be related to poor indoor air quality. Results of the monitoring are compared with available guidelines for IAQ and concentrations measured in UK homes and offices during other BRE studies. The study identifies a potential for achieving improved air quality by use of low emitting products.
