The steady pressurisation method measures the building leakage in a range of high pressures, typically 10-60 Pa. It is implemented by creating a steady pressure difference across the building envelope and measuring the corresponding airflow exchange rate between the indoor and outdoor simultaneously. This method has been widely used and accepted as the standard test for demonstrating building air-tightness compliance. Conversely, the novel pulse technique, has been developed to measure the building air leakage at low pressures typically in the range of 1-10 Pa.

This paper introduces an experimental study of enclosure airtightness testing of an outdoor chamber using both the pulse technique and the blower door method. This investigation is a 2nd stage comparison study following the previous testing of a house-sized chamber in a sheltered environment. The outdoor chamber in this study has dimensions, approximately half that of a standard 20ft long shipping container. Multiple openings were installed into the chamber’s envelope to provide a leakage level and characteristics similar to an average UK house.

Furniture can raise indoor air contaminants with toxic emissions of VOC and formaldehyde.. While furniture is classified as a subject of safety and has quality labeling, there is a lack of domestic regulations related to contaminant emissions with the exception of sinks. When looking at the analysis on environment-related patients related to the smell or odors from furniture every year, patients suffering from asthma, allergic rhinitis, and atopic dermatitis are on the rise.
