4RinEU demonstration activities: where do we stand?

European construction sites have been hit hard by the recent COVID-19 pandemic. 4RinEU looks to the future.

Energy

Haugerudsenteret (Oslo, Norway) – Our first success story. Energy performance to be assessed The Norwegian demo case, located in Oslo, is the first example of a successful implementation of 4RinEU methodology. The renovation works took place in the second half of 2018 and lasted only eight weeks, during which the tenants kept living in their dwellings. The interventions implied a massive use of 4RinEU timber prefabricated technology to refurbish both the roof and the façade of the building, the latter being integrated with new windows and PV panels. New air handling units connected to the prefabricated façade by means of ventilation ducts have been installed in dedicated technical rooms. Our researchers are currently analysing the data collected before and after the renovation works to assess the improvement of the building’s energy performance.

Our strategy here includes the application of a timber prefabricated façade with integrated sun shadings, the replacement of balconies and the enhancement of the HVAC (Heating, Ventilation and Air Conditioning) system through the introduction of mechanical ventilation with heat recovery. The renovation works were supposed to start towards the end of March with a view to being completed by May. Due to the global emergency caused by COVID-19, the building site had to stop its activities. Despite this, the production of prefabricated façade modules could go ahead as planned, and so did the evaluation process for the installation of the monitoring system which will allow us to compare the building’s performance in terms of energy efficiency before and after the interventions. The construction site will reopen by July 2020. La Vall 9 (Bellpuig, Spain) – Tender to find a constructor postponed The Spanish demo of Bellpuig consists of a recently built multifamily house with poor performances. 4RinEU will renovate the east-oriented main façade by installing timber prefabricated façade modules, which will include new windows with shading system, decentralised ventilation machines with heat recovery and PV panels. The placement of the façade has been optimised using EarlyReno, a tool created by the project to help designers and professionals choose the best renovation strategy to maximise the use of renewable energy. In line with the other demos, a monitoring system will be set-up to evaluate the performance in the pre and post retrofit condition. After a few months of closure, the activities in Bellpuig are now resuming, starting with the procurement process for the selection of a constructor. Renovation works will start by autumn 2002 and will last approximately four months from the appointment of the construction company. A new demo: Pinerolo, Italy The recently acquired demo case of Pinerolo, Italy, will see the implementation of the 4RinEU plug&play hydronic technology in a multifamily house with 13 dwellings. The renovation concept that will be tested in this demo is based on three pillars: reducing fossil fuel consumption, increasing the efficiency of the HVAC and finally producing and delivering DHW (domestic hot water). The project involves the installation of an inverse heat-pump connected to the existing condensing boilers via hydronic modules.
