The Portuguese Pilot Building has recently undergone extensive renovations to improve living conditions, tackle key issues such as humidity and heat loss, and prepare for the integration of SUREFIT technologies. The Municipality of Mafra, which owns the building, has been responsible for part of this refurbishment. They have replaced windows and frames, and carried out internal waterproofing and painting to enhance the building's durability and aesthetic appeal. Additionally, CJR has made significant upgrades to the building's infrastructure. They have revamped the hydraulic and electrical systems, ensuring a more efficient and safer environment. Furthermore, CJR has replaced two windows and their frames to accommodate advanced technologies such as PV Vacuum Glazing and Window Heat Recovery. These specific interventions aim to boost energy efficiency, reduce energy consumption, and provide a more comfortable and sustainable living space. This comprehensive renovation not only addresses existing problems but also equips the building with state-of-the-art, eco-friendly technologies.

The Surefit renovations in the Greek building concern the 1st floor of the building. The PV-Thermal system provided by SOLIMPEKS was installed. In addition, the WINCO membrane was installed on the ceiling of the ground floor (that is a non-heated/cooled space) in order to enforce the insulation of the 1st floor. The balcony doors of the 1st floor were replaced with double glazed energy efficient balcony doors with PVC frame and roller shutters. The prefabricated facade panels provided by CJR were installed on the North and South facades and the PV vacuum glazing windows provided by UNNOT, were placed in one balcony door on the South facade. Moreover, sensors and actuators for controlling the active systems was installed by AMS.

The Surefit project installed seven technologies that allowed the home to achieve significant reductions in primary energy consumption, CO2 emissions, and monthly operating costs to the residents. The technologies were monitored for 18-monhts, allowing assessment throughout the year, to include the long cooler winters and the warmer summers of the UK. The Smart Control system allowed the solar PV systems, heat pumps, window heat recovery unit, and storage systems to be controlled with minimal user input, providing comfort and optimum energy use. The novel insulation systems greatly reduced the heating and cooling requirements of the home.

The Surefit renovations in the Spanish building improved insulation, energy efficiency, and daylight management. A PV-Thermal system and prefabricated facade panels with silica aerogel and XPS were installed to enhance thermal performance. PV vacuum glazing windows and a breathable membrane further optimized insulation, while PCM panels contributed to temperature regulation. Smart controls and window heat recovery units improved energy efficiency, and daylight louvers enhanced natural lighting while reducing overheating risks. Monitoring results confirmed a nearly 60% reduction in primary energy consumption, improved airtightness, and lower thermal losses, demonstrating the effectiveness of prefabrication and renewable energy solutions in deep retrofits.

The SUREFIT daylight louvers were installed on bedroom and dining room windows at the Finnish demo site. The installation, carried out by the team from AALTO, proceeded smoothly and was completed in a couple of hours. The apartment's occupant was present during the installation and had positive first impressions of the louvers. Subsequently, the remaining louvers for the balcony windows were also installed, with this process again proceeding without any issues and taking a few hours. Monitoring of the indoor conditions in the apartment is ongoing to determine the effectiveness of the louvers in improving them.
