Flaw in NSAI retrofit code raises ventilation concerns
The National Standards Authority of Ireland
has appeared to acknowledge a major
discrepancy spotted by Passive House Plus
in SR 54, its code of practice for the retrofit
of homes, that could give rise to inadequate
ventilation and poor indoor air quality in
some dwellings upgraded to the code.

But many in the green building sector are critical of the decision, and some are questioning the value and purpose of Agrément. Lenny Antonelli reports.
