Studies on the role of fungi in Sick Building Syndrome

Fungi presence are often liked to the sick building syndrome. In this paper the authors describe two case studies on the role of fungi in the occurrence of SBS.

Creating mold-free buildings : a key to avoiding health effects of indoor molds

The author advises a commitment to a philosophy of proactive preventive maintenance for home, apartment, school and commercial buildings. Preventive actions would result in considerable cost savings, and save building occupants from major health problems.

Residential exposure to volatile organic compounds and asthma

A literature review finds that observational studies have found a correlation between exposure to VOCs and asthma, whereas interventional studies did not manage to show it. This paper studies two hypothesis to explain that discrepancy in findings.

Outline of a methodology for construction of a healthy building (Article in portuguese)

This paper gives the description of the outline of a methodology whose aim is to decrease or even eliminate the emissions resulting from building materials.

Outdoor/Indoor/Personal ozone exposures of children in Nashville, Tennessee

That study was conducted in Nashville (TN) : during six weeks, measurements using passive ozone samplers were made on a group of school children aged 10 to 12 to estimate the outdoor/indoor /personal ozone exposure. Personal ozone exposure depends of the time spent indoors and outdoors.

Modeling of occupant-generated CO2 dynamics in naturally ventilated classrooms

This paper presents a numerical method to estimate the concentration of occupant-generated C02 for the occupancy found in elementary school classrooms with nonforced ventilation.

How unbalanced return air encourages mold growth

There are two ways for unbalanced return air to produce moisture and mold problems during hot and humid weather : - the increased entry of outdoor air that substantially increases indoor relative humidity. - a negative pressure can draw moist air into wall cavities causing a moist interstitial microclimate, if indoor humidity is relatively low in the conditioned space.To prevent the creation of moisture and mold problems, properly sized return ducts should be provided.

Comparison of outdoor and indoor mobile source-related volatile organic compounds between low-and-high-floor apartments

The hypothesis that there is a vertical variation in mobile source-related volatile organic compound (VOC ) concentrations in high-rise apartment buildings is examined in that paper.

Quantification of the effects of air velocity on VOC emissions from building materials

The effects of environmental factors can be important in simulating indoor levels of VOCs emitted from building materials. In this study the effort has been made to quantify the relationship between air movements and emissions of decane applied on an oak substrate.
The aim of this research is to determine the correlation between environmental factors and coefficients of mass-transfer based emission models in a mathematical form.

Investigation of building materials as VOC sources in indoor air

This paper give descriptions of the tasks conducted in the two phases of the material emissions project that lasted from 1996 to 2000. The main aim of that client-supported project was the creation and maintenance of a material emission database and single-zone indoor air quality simulation program called MEDB-IAQ.
