Description and contextualization of the subject
This course focuses on teaching the students how a high performance envelope is designed based on the local weather conditions, building orientation and use. The course starts with the heat, air and moisture transfer mechanisms that occur within the building envelope. Then, selecting the best thermal resistance and thermal inertia combination for building envelops walls is given. The selection of the windows regarding thermal transmittance, solar heat gains and how to optimize the solar shadowing or reflecting systems are also studied. To finalize the course, different solar active and passive building envelope solutions are presented and explained, such as: green roofs and walls, Building Integrated photovoltaic systems, ventilated façades, etc.Teaching staff
