COMHAIRLE CONTAE ÁTHA CLIATH THEAS
SOUTH DUBLIN COUNTY COUNCIL
MEETING OF TALLAGHT AREA COMMITTEE
Monday, April 27, 2015
MOTION NO. 11
MOTION: Councillor C. King
That this Committee calls on the Chief Executive to report on the pilot ventilation in Council homes programme that took place a couple of years ago and what plans if any are there to roll out a programme throughout the Tallaght area with a view to improving the quality of air in homes which is in some cases causing sickness in tenants when dangerous spores appear due to bad ventilation.
REPORT:
The pilot ventilation project, using a supply/demand system, was successful for the dwelling where installations occurred. There was a substantial reduction in free moisture/condensation in all dwellings.
A number of conditions applied to the pilot dwellings that could be effectively addressed by the system:
- Ground floor units - security issue with opening windows
- Small units [visitors or continuous occupation increased humidity]
- Excess moisture generated within dwelling
- Intensified washing generated due to requirements of young families
- Intense use of dwelling on continuous basis
- High air tightness of dwelling rending normal ventilation less effective
- High air tightness / lack of cross ventilation
The system has been extended in the interim to a new build project with a high air tightness ratio and also to an apartment block complex where the units are small, cross ventilation is difficult and the air tightness has been increased.
The installations have operated for 18 months with some reported success and with no negative comment.
It is anticipated that the system will be utilized in refurbishment/new housing programs where the conditions justify the installation cost.
