Learning outcomes
At the end of the course the student will have acquired an in-depth knowledge on the thermal behavior of the building system and has acquired the design skills for different types of technological envelopes and HVAC plants for closed spaces.
Course contents
The course program include following lectures
- Heat transfer in building structures. Stationary behaviour: thermal resistance and transmittance. Dynamic behaviour: transfer function approach. thermal capacity. Convenction and radiation on building surfaces. Heat transfer in cavities. Modelling with Energy plus.
- Overlook on thermal performances of traditional and advanced materials and envelope systems: massive and light walls, insulating materials, PCM green wall/roof.
- Vapour diffusion in structures and condensation risk: Glaser Diagram. Examples
- Solar Radiation and performances of transparent systems. Advanced windows systems: low emission glasses,solar control gl., electrocromic gl.(1). Solar Greenhouse.
- Indoor Air Quality, Ventilation and infiltration: modelling of air flows. Natural ventilation examples.
