Project Description

The purposed project is a longitudinal study aimed at conducting multi-zone indoor environmental quality monitoring in 100 'A' rated energy efficient Irish residential dwellings. The project will monitor environmental quality (temperature, humidity, CO2, radon and VOCs) over two heating sessions and a cooling season. This will generate over 300 million time-series data points, which will be stored in a repository and freely accessible to all relevant stallholders. This will provide an accurate representation of the effectiveness of whole-house ventilation as opposed to snapshots of individual rooms and periods. Questionnaires will be administered concurrently with the monitoring data to capture information on occupants awareness of their ventilation system, their thermal comfort and overall satisfaction, and identify any potential mould growth. An advanced modelling framework will be developed, parameterised based on the empirical data to established a number of baseline scenarios. Simulations will examine the capability of achieving a balanced energy and ventilation performance in 'A' rated dwellings. Simulations-based assessment of the effectiveness of the ventilations systems will be carried out under different ventilation control mechanism and projected future policies. Overall, a comprehensive and scientifically robust assessment of the effectiveness of the ventilation system in 'A' rated dwellings will be carried out.
