The Rannaliiva building was built in the 80ies and host 16 dwellings in 2 floors, for an overall size living area of 1307 m2 (net area). The building retrofitting interventions during the RenoZEB Project will include:
- the refurbished of the building envelope (including façade and double-glazed windows);
- the installation of a RenoZEB low invasive ventilation system to provide heat recovery (minimum energy efficiency of 80%);
- the replacement of the heating system and the installation of a metering system to allow the efficient operation of energy consumption.
With the implementation of the designed retrofitting measures, it is expected a 60% reduction of energy consumption and primary energy respectively.
