This case study looks at the overall air quality in the western glass stairwell of Lawrence Hall. Upon initial inspection, the air feels stagnant, humid, and uncomfortable. The stairwell is constructed of sheer glass walls on the north/south sides and concrete on the east/west sides. The glass has direct contact with the surrounding environment (i.e. trees and moisture). The materials used in the stairwell, combined with the exterior environment do have an effect on the interior climate of the stairwell. The CO2 levels are analyzed and compared to the ASHRAE 62.1-2013 standards. The humidity, light intensity, and temperature levels are compared to ideal environments for moss and mold. The most important factor contributing to the growth of moss and mold (MEEB Table 5.1) is humidity. The growth of moss/mold contribute to the overall air quality of the staircase. Observations of the staircase led to two hypotheses:
1. The air quality of the glass stairwell in Lawrence Hall is below the ASHRAE 62.1-2013 standard.
2. The variation of materials used in the stairwell aids in the growth of moss and mold.
Through testing using a CO2 meter, the first hypothesis was proved wrong, indicating healthy CO2 levels in the staircase. Using HOBO dataloggers, the temperature, light intensity and relative humidity the second hypothesis was proved right, indicating the perfect environment for growth of moss and mold. Studies such as these are important in the design and construction of new buildings when considering materials and environmental factors.
