NZEB OPEN Doors 2016


Tom Clarke House

Bedsit Amalgamation to One Bedroom Dublin City Council, Senior Citizen Apartments achieves the NZEB retrofit standard and was open to the public on 12th November, 2016.

Tom Clarke House is a late-1950’s development comprising of 24 bedsit units, in three, two storey blocks with deck access situated in a U-shaped courtyard arrangement in a cul de sac, which has passive supervision from the adjacent 2-storey houses.

The buildings were wrapped with external insulation, the attic and ground floor were further insulated to provide higher levels of comfort for the occupants as well as achieving higher energy ratings and reducing carbon emissions. A demand controlled ventilation system was installed and best practice levels of airtightness permeability were achieved. Key junctions were thermally modelled and a bespoke Y factor was calculated for each unit type.

The previous BER ratings have been assessed at an average G rating and the refurbished units resulted in an 80% improvement to B3 and B2 BER ratings, within the criteria for NZEB existing building targets.
