AbstraktThe term “atrium” is used to refer to a sheltered volume within a building. Glazed atria have become popular in the last years because of their attractive features. These atria are built in the form of large glazed spaces that allow occupants to experience distinguishing positive aspects such as daylight, natural appearance and vegetation. Even if atria benefits are relevant during winter season as such structures are meant to take advantage of solar radiation to provide natural heat and light, during summer atria are often reported to be responsible of thermal discomfort and overheating problems due to the solar penetration surplus.
This paper presents the results from a long term monitoring focused on the glazed atrium of the “Dell’Angelo” hospital in Mestre, Italy. Recently built, is one among the most significant examples of glazed structure in Italy. Results are intended to describe the thermal characteristics of the investigated space under typical Italian summer conditions in terms of the resulting thermal conditions people and patients are exposed to.
