**5. Conclusion**

This chapter focuses on wooden facade renovation and additional floor construction as ecologically sensitive engineering solutions from the Finnish residents' point of view. In doing so, the challenges of facade renovation and the benefits of additional floor construction are presented.

In the context of the transition to service-oriented business solutions in Europe, future and emerging technologies in facade renovation and additional floor construction can make a difference with the risks of overheating from climate change and the reduction in energy demand for cooling in existing buildings, considering the humancentered design approach and emerging intelligent building operating systems such as digital platforms and control strategies. It will help Europe become an early leader in these promising technologies and will focus on building energy efficiency and the productivity and well-being of building occupants to renew the foundation for future competitiveness and growth in the coming decades.

Significant market acquisitions must be initiated to transform facade renovation technologies into mainstream technologies. This includes innovations in low-impact and climate-sensitive refurbished buildings through unexplored collaborations between advanced multidisciplinary design teams and innovative facade engineering. The European Energy Performance Building Directory (EPBD) highlights the importance of comfort, smart readiness, and high energy efficiency of buildings to be renovated [59]. With climate change and the increasing risk of overheating, the potential for the building renovation industry to renew the basis of its future competitiveness and growth and increase the use of facade refurbishment technologies and additional floor construction in the future is high. At this point, residents' attitudes toward new construction methods such as timber facade renovation and additional floor construction play a critical role in the spread of these practices and contribute to the transition to a forest-based bioeconomy, the decarbonization of buildings, and a zero-energy building approach in Finland.

This study revealed the characteristics that residents value and guided those concerned about the direction in which residential areas should be developed. According to the results, residents were ready for large-scale use of wood in suburban development and renovation. The decision is ultimately made by the homeowners' positive attitude toward wood facade renovation, and the additional floor construction is an encouraging display of the enormous potential of the construction method. The additional floor construction contributes to overcoming the obstacles encountered in the difficult facade renovation process. Wood as a renewable material and carbon sink as a working material should be used for suburban regeneration as an ecologically

responsive engineering solution to contribute to the decarbonization of buildings and a zero-energy building approach.

The results of this chapter were based on the empirical approach—residents' survey—but further research such as energy analysis, wood-based facade renovation, and additional floor solutions, developed prototypes testing will be done as part of other studies by following the methodology suggested in **Figure 6.**
