Ms Orla Hegarty:

No. I sought that from the Department because I wanted a list compiled. Numbers were sought from local authorities.

I will address the issue of dampness. Building regulations are clear about ventilation, insulation and building physics. Perhaps the committee will return to this issue. The building energy register compiles all of the data for building energy for buildings that have grant-funded upgrades or new buildings. It captures a large amount of data on building physics. Two issues have become clear from the initial research done on that building energy register. First, there is substantial non-compliance in BER certificates and this issue needs to be addressed. Perhaps the Joint Committee on Climate Action will address that. Second, there is an indication that there are issues with ventilation and insulation, which will have an impact on indoor air quality and people's health. This is a substantial issue which needs to be actively addressed. There are issues with conflicting regulations, on which work is under way. There is also the broader issue that not much has been built, particularly houses, for the past ten years. There has been a rapid change in regulations and a lack of upskilling, public information and technical details about these changes that people can use. As the details that are publicly available are not up to date, people are using out-of-date information on how to put together materials on building. It is a significant issue.

Will Mr. O'Mahony or Mr. Bluett comment please?
