At the end of the course the student is expected to: - be able to recognise, classify, describe and detail building envelope technologies for existing and new buildings; - be able to design building envelope technologies with a focus on the primary functions of the building envelope: (i) Structural safety and stability, and integration with primary structures; (ii) Thermal and solar performance, weathertightness and integration with other building systems; (iii) Architectural image through detailing and interfaces control, considering also manufacturing aspects, costruction site processes and maintenance These abilities will be developed also by means of a design application, consisting of a building envelope deep refurbishment project of an existing building in the city of Torino, considering at the same time structural, detailing and performance aspects.

Students must have good knowledge of the main topics dealt with in the field of: - Structural mechanics and design: strength of materials (BSc level), solution of isostatic assemblages of beams, theory of plates, evaluation of stresses and deformations in beam and plate elements, definition of the load combinations. - Building Physics: heat transfer in the building envelope, material thermal and optical properties (i.e. thermal conductivity, specific heat capacity, solar absorption, reflection and transmission, emissivity etc), building envelope thermal characteristics (i.e. U-value, g-value, Tvis etc.) - Architectural Technology: technological design of main interactions between building subsystems; detailed design of compliant technical solutions of opaque and transparent envelope; technical characterisation, compatibility and in-service behaviour of components, elements and materials; critical evaluation of product data sheets. These pre-requisites are in line with the topics taught in the Bachelor degree at Politecnico di Torino of Building Engineering, Civil Engineering and Architecture. Moreover the students are required to: - have a consolidated know-how of techniques of representation and communication of the project, both with reference to the more traditional forms of communication (perceptive, design sketches, physical models, etc.), and with reference to digital representation techniques (virtual modeling and rendering etc.); - be aware of design choices consistent with the energy and ecological transition; - be aware of design choices consistent with a circular-oriented design approach.

The course is organised in 3 modules and on project-based activities: Module 1 - Architectural Technology (20h between Lectures and EA): - Facade systems: modular design principles and technological solutions. - Curtain walls and metal- based facade systems - Lightweight and heavyweight opaque facade systems (rainscreen, ETICS, partly prefab and prefab modules) - Coordination with primary structure, dimensional coordination, joint types choice, tolerances definition - Laying sequences definition and detailing - Maintenance and Accessibility - Dismantling & Design for disassembly Module 2 - Building Physics (20h between Lectures and EA): - Facade engineering and facade design process and simulation for facade engineering - Thermal performance - Solar performance and glazing systems - FEM calculation for thermal performance and condensation and thermal shock in glazing - Weathertightness - Fire resistance and fire spread in facades - Facade commissioning / tests - Simulation for high performance and responsive facades, operational energy and embodied carbon Module 3 - Structural mechanics and design (20h between Lectures and EA): - Facade structural typologies, systems and components - Definition of loads and load combinations according to Eurocode 1 - Deformation and interplay with the primary structure of the building - Lightweight facade design and sizing (aluminium, steel, timber mullions and transoms) - Heavyweight facade design and sizing (precast concrete walls and claddings) - Infill glass units design (Insulating Glass Units and laminated glass) 20 h review of Project Based Activity: group activity to develop the engineering of a facade system from concept to developed design, to so be able to document elements sizing, system performance and details up to 1:5 scale of the building envelope developed, communicated through technical drawings and design report (including basis of design and performance specification).

During the course different seminars will be organised involving industrial players (from manufacturing and design), which will most likely include a factory visit and a survey walk to see engineered facade examples.

The course is organised in 3 modules and on project based activities (60% lecture, 40% practical activities), organised as follows: - Module 1 - Architectural Technology (20h: approx 15 Lectures 5 EA) - Module 2 - Building Physics (20h: approx 15 Lectures 5 EA) - Module 3 - Structural mechanics and design (20h: approx 15 Lectures 5 EA) - 20 h review of Project Based Activity - 3-4 seminars per year from industry players - 1 visit to building envelope elements / systems factory - 1 Facade walk (survey of existing facade) with designers

Exam: Compulsory oral exam; Group project;

The exam will be conducted through a summary discussion of the individual and group project path, documented by graphical elaborations, digital models and short illustrative writings, supported by the oral discussion of the various materials, including intermediate ones, produced by the student during the design studio. The assessment will take into account the following aspects, evaluated on the basis of the final (at the exam) and intermediate (during the semester) submissions produced, discussed individually during the final interview: - Ability to design a building envelope system from a structural, performance and detailing point of view; - Conscious critical use of design tools to develop the building envelope design; - Ability to communicate the engineered design by means of technical reporting and presentation by means of engineering drawings. The exam will consist of the presentation of the design developed through the course, with a discussion on the specific topics of each disciplines, and the discussion of the individual work. The final mark of the module is obtained from the mark of the final exam and from the marks of the single disciplines, each taking in account the following criteria: > Quality of the project and completeness of the presented work at the exam according to the requirements for each subject (Architectural Technology, Building Physics and Structural Mechanics); > Oral discussion with single group components, deepening with questions (relative the to project) the three subjects of the course; > Respecting Deliverables timelines and completion of the project (penalties with be arranged at the exam in terms of grade, i.e. -2 points); > Continuity of work during the semester and presence at all the reviews; > Evolution of the project in the intermediate deliveries. The final mark is obtained as the weighted average evaluation of single disciplines concerning the final exam and the individual works, in 30/30.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
