Type of construction: 2D facade renovation and 3D volumetric addition
Typology: Residential, circa 60m2
Owner: Local Authority – Dublin City Council
Construction systems: Concrete floors and walls with timber intermediate floor and roof
Location: Ireland, Dublin, Crumlin
The building that constitutes the case study is a typical Irish terraced house made of bricks. The dwelling is located in the extended Dublin area and it was built in the 30’s. Suspended timber floors fitted in most of the property. The bricks visible in the main front façade are not decorative but are part of the structure itself. This leads to the fact that the insulation is practically non-existent, and the U value of the external walls would reach very high levels (as suggested from the Tabula for similar buildings, about 2.1 W/m2K).
The reconstruction of unused or uncomfortable spaces makes it possible to implement new volumetric additions designed based on the H2020 ABRACADABRA project strategy and also using the Pro-GET-onE input and know-how of applicable products for end-users like several types of prefabricated elements for volumetric increase or buffer zones (i.e. sunspace between the building and the outdoor environment, extra room, etc.). In this case, we will reuse land and existing construction materials stimulating circular local economy. It will Foster circular economy, including using of pre-fab elements to solve the boundary condition limits of the building (avoiding excavations involving the adjacent properties.
We expect the following results in Dublin:
Case specific outcomes:
This type of intervention can trigger a systematic urban renovation at a neighbourhood level, minimizing occupants’ discomfort, increasing industrialization of the components needed for the energy retrofit. Moreover, there will be a significant increase of the real estate value and a shortening of payback time of renovation, representing also an opportunity for local construction companies who can foster this type of strategy.
