The Causes Of Surface Condensation And Mould, And The Responsibility Of Relevant Parties To Alleviate Them, Joseph Little Jun 2021

The Causes Of Surface Condensation And Mould, And The Responsibility Of Relevant Parties To Alleviate Them, Joseph Little

Reports

All over Ireland large numbers of people live in unsanitary conditions suffering poor indoor air quality, surface condensation and mould. Where the occupants are tenants the cause of the conditions and identification of the parties responsible can cause much stress. Condensation and mould growth on the internal surface of a room are caused by a combination of factors due to specific conditions. In severe cases, one of these factors may lead to surface condensation and/or mould growth, but in general, surface condensation and/or mould growth occurs when two or three of these occur together. Even though multiple causes and shared …


A Risk Framework For The Delivery Of Long-Term Performance Through The Large-Scale Energy Focused Retrofit Of Housing, Seamus Harrington, Mark Mulville Dr Jan 2021

A Risk Framework For The Delivery Of Long-Term Performance Through The Large-Scale Energy Focused Retrofit Of Housing, Seamus Harrington, Mark Mulville Dr

Conference papers

The 2019 Climate Action Plan (Ireland) seeks to retrofit approximately 500,000 existing homes to attain a B2 Building Energy Rating by 2030. Although not without merit, this presents a number of risks. The authors, through a review of relevant literature and a survey of leading experts in the field of domestic retrofit, set out to explore if and how the implementation, execution, and performance of retrofit strategies that utilise a uniform approach to the retrofit of the decidedly non-uniform existing dwelling stock could create un-intended consequences. It is demonstrated how issues related to indoor air quality, comfort and overheating may …


Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf Jan 2015

Ventilation Rates And Airflow Pathways In Patient Rooms: A Case Study Of Bioaerosol Containment And Removal, Ehsan S. Mousavi, Kevin R. Grosskopf

Durham School of Architectural Engineering and Construction: Faculty Publications

Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research suggests pathways between pathogenic source (patient) and control (exhaust) may be the dominant environmental factor. While increases in airborne disease transmission have been associated with ventilation rates below 2 ACH, comparatively less data are available to quantify the benefits of higher …
