Demo cases - Challenge

The challenge we face

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).

What we will do

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.

The results we expect

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.

Case specific profits:

  • Prefab P & P solutions for facades, roofs, additional modules, both 2D as 3D, faster renovation and acceleration of the process
  • Improvement of real estate value for the owners through the extension of flat area. When there is a sufficient space around the building, the modular systems will be adopted to enlarge the usable area of the housing unit. Typical extension will be small additional structures of the existing building such extra room or larger glazed winter gardens.  
  • user orientated technical solutions connected with the consumers’ daily habits, expectations and aim to reduce energy use.

Case specific impact indicators:

  • The Percentage of primary energy saving after renovation (measured in kWh/m2 y) is 78%
  • Amount of primary saving after renovation 0,035 GWh/y
  • Percentage of CO2 emissions reduction (measured in Kg/ m2 annually) is 80%
