1. Introduction to the course; surveys and diagnostics in building renovations; historical development of buildings in the Czech Republic. 2. Energy savings in retrofitting of external walls – part 1: fundamental overview; variants of thermal insulation applications; design criteria and methods of implementation; specific approaches for different wall material solutions. 3. Rehabilitation of selected building structures and improvement of their thermal performance: ceilings, floors, partitions, windows and doors. 4. Energy savings in retrofitting of external walls – part 2: protection of birds and bats on the construction site; local repairs of ETICS; occurrence of algae on ETICS; rehabilitation of ETICS. Summary of legal and standardized requirements on design documentation of building renovations; the most common defects and failures in the implementation of energy saving measures. 5. Renovations of flat roofs: defects and failures, recovery of function and improvement of thermal performance. 6. Renovations of pitched roofs: defects and failures, recovery of function and improvement of thermal performance. 7. Introduction to pre-cast concrete buildings: historical development of standardized construction systems and their envelope walls. Energy savings in retrofitting of pre-cast concrete buildings, defects and failures of envelope walls, modifications of balconies, loggias and parapet walls. Practical examples of the implementation of energy saving measures. 8. Energy savings in retrofitting of curtain walling: unitised construction and stick construction, glazed facades, historical curtain walling. Wood-based structural systems. 9. Energy savings in retrofitting of building equipment: fundamental overview, spatial requirements, related construction works (placing of pipes and wires, rehabilitation of chimneys, installation of heat pumps, HVAC, etc.). 10. Energy savings in retrofitting of historical and heritage buildings: contemporary legal requirements and other regulations in the Czech Republic, conservation versus interventions. Final exam instructions.

1^st – 3^rd week: Introduction to practice classes; requirements; assignment of input documents for semester work. Consultations of the assignments and individual field work:

• field sketches and photodocumentation, collection of necessary background information;
• preliminary building survey, including a preliminary assessment of the current state;
• technical drawings of the existing state of the chosen object (M1:50).

4^th– 8^th week: Design of the building retrofit (emphasizing energy savings), individual consultation:

• retrofitting of selected building structures and improvement of their thermal performance: external walls, plinth, ceilings, floors. Including assessment in terms of building physics;
• retrofitting of windows and doors and improvement of their thermal performance;
• design documentation of the external thermal insulating composite system (ETICS), including a technological work procedure;
• renovation of flat or pitched roof: recovery of function and improvement of thermal performance;
• design documentation of building retrofitting (M 1:50), including the solution of selected assembly details.

9^th week: Individual consultation; presentation of the results.

10^th week: Submission of semester work; credits.
