Implementation of ventilation in existing schools: a design criteria list towards passive schools

Present paper analyses the best-practice solutions for classrooms’ ventilation that fit the objective of quick and inexpensive implementation. The paper decomposes the relations between ventilation and building into manageable elements and analyzes them. The analyses are performed qualitatively; they evaluate both scientific and practical implementation The analyses lead to a list of criteria associated with the implementation of ventilation in existing schools.

Generic retrofitting scenarios which prioritize energy savings, indoor climate and building/facade integration are assembled and illustrated to target and offer design advice to the different stakeholders/focus groups: professionals and users.
