Waldo Galle

As a doctor and master of science in architectural engineering, Waldo conducts fundamental research on the financial and technical feasibility of transformable buildings at the Vrije Universiteit Brussel. Therefore, he develops divergent building scenarios allowing him to advise architects, investors and governments about the robustness of their design choices.

During his education as an architectural engineer (graduated summa cum laude in 2011 at Ghent University), he received an extensive training in the application of material, physical and structural sciences. Furthermore, his experience at the architectural office Boulez-Degrande perfected his technical knowledge and allowed him to explore his inventiveness.

This technical and conceptual experience are of great advantage during his research and consultancy. At this moment Waldo is appointed as a project researcher on the 'Bâti Bruxellois, Source de nouveaux Matériaux' study. A study made possible thanks to the support of the European Regional Development Fund (EFRO/FEDER).

Transformable building is an innovative design and construction strategy. It aims for an adaptable building stock and fosters the future reuse of construction materials. As a result, long-term environmental and financial savings could be realised. Nevertheless, a feared increase of the initial cost impedes this strategy’s widespread implementation. To frame this impediment and gain better insight into the financial consequences of transformable building, the present research proposes an enhanced life cycle costing method. Taking into account the circular service life of transformable buildings this method empowers advisors and designers to evaluate the feasibility of transformable building and implement it in a well-conceived way.

To take into account the circular service life of transformable buildings as well as their unpredictable and dynamic nature the proposed method departs from life cycle scenarios. Such scenarios or imaginable futures reflect our varying requirements. To facilitate their integration in the life cycle cost analyses the present research developed five new features. These features include specific calculation methods as well as detailed modelling protocols. To illustrate their added-value an in-depth case study is conducted. The study’s outcomes show how scenario based life cycle costing allows to compare initial and long-term costs, evaluate model uncertainties, identify boundary conditions, understand design improvements and study investment risks.

During his master dissertation Time based design Waldo Galle became familiar with the concept of transformable building typologies. In his conviction of the current need for a new approach to our built environment he introduced the subject himself at the Ghent University. Time based design takes into account the changes which buildings should under go during their lifetime.The need for those changes can be clearly deduced from the accelerating dynamism of our society. For that reason, a design which anticipates on those changes is essential. Subsequently, the environmental load of constructing can be reduced and more opportunities are offered to the user.

Since he has been making a broadening study on design aspects of transformable buildings, he made acquaintance of the majority of international research in the field. But most it were the numerous brainstorming sessions with his promoter and mentors, the process of trial and error and the ultimate breakthrough that have strengthened his interest in academic research. The dissertation was made in a collaboration with æ-lab at the VUB. Within the field of Transformable Design, directed by Prof. dr. ir. arch. Niels De Temmerman, the lab had developed a substantial expertise related to transformable shelters, mobile scissor structures and the interchangeable refurbishment of social housing.
