Data Analysis.………………………………………………………………………………………………..10

Mould thrives in constantly moist environments that have continuous exposure to moisture due to weather damage, leaks, or improper construction experiencing mould growth. In many cases mould may continue to build up behind walls and fixtures and may be difficult to locate.

Mould spores can trigger asthma attacks, headaches and allergies, and other serious respiratory ailments. High humidity levels sustained over time promote mould growth. Beyond health effects, humidity levels affect thermal comfort and overall air quality.

Based on the site visit, and literature review, hygrothermal performance of the Pierhead Building is identified as a case to be monitored to assess a response to the following questions: -

A. Where is condensation observed?

B. Where is mould growth observed? Are there any signs of prominent mould spores?

D. What are the favourable conditions for the cause of condensation and mould growth?

D. Where is mould most likely to grow in future?

E. Does the occupant survey show any signs of respiratory ailments?

F. Is there a need for mechanical ventilation (dehumidifying or exhaust) in affected spaces?

G. Is there a need for moisture sensing/ regulating systems for the preservation of historical elements?
