A Survey on Daylighting Education in Italian Universities : Knowledge of Standards, Metrics and Simulation Tools
Daylighting is a strategic topic to achieve sustainable buildings, so it is more and more imperative that it is implemented in architecture curricula to prepare a new generation of daylighting-oriented practitioners. In this frame, the DAYKE project (Daylight Knowledge in Europe) was set up to explore the level of knowledge about daylighting among European professionals and students. DAYKE-Europe was replicated as DAYKE-Italy to study the knowledge of daylight standards, metrics and software among Italian architecture students, and to compare it to that observed within DAYKE-Europe. A sample of 542 questionnaires were collected in five universities. Primary outcomes were: (i) a general low …
Questionnaires and simulations to assess daylighting in Italian university classrooms for IEQ and energy issues
Abstract Results from the DAYKE-Italy project are presented. An investigation on daylighting in eight classrooms in five Italian universities was carried out through a combined approach: an ad-hoc survey administered to students to investigate how they perceive daylight in classroom, and numerical simulations (DIVA + ALFA) to calculate a set of objective metrics (daylight, circadian, and energy-related). A sample of 542 questionnaires was collected through two sessions and the subjective judgments were correlated to objective metrics. Results from descriptive and statistical analyses showed: (i) the correlation was significant for all daylight metrics: among them, average daylight factor an…
Energy Equalization and the Case of the “nZEB Hotels”
Nowadays, energy equalization is one of the many issues concerning the energy policies on the urban scale and in the perspective of reducing the Urban Heat Island effects (UHI-e). The different economic-financial profiles of the interventions implemented in the buildings having a wide range of climatic locations, typological arrangements, architectural-historical constraints, need to be coordinated within unitary local energy-environmental policies inspired by economic-financial as well as environmental issues. The renovation of existing hotels to achieve a nearly Zero-Energy performance is one of the goals of the 2050 EU’s energy policy. This paper presents the nZEB retrofit case of an exi…
