St Bricin’s Park Block 2 is an apartment block built in the 1960s for senior citizens refurbished to Passive House Standard, known as EnerPHit. The Construction team undertook a bespoke Passive House Tradesperson’s Course, along with members of Dublin City Council’s design and maintenance staff. A key challenge in the retrofit was achieving a high standard of air-tightness which took significant time and work which paid off due to the skills and dedication of the construction team.This block achieved a BER of A3 (from E2). For this, the project received an SEAI Deep Retrofit Grant in 2018 and achieved the Passive House EnerPHit standard. Retro-fitting the properties allows residents to stay in their communities in comfortable, healthy and affordable homes.
