Effect of Climate Change on Building Performance: the Role of Ventilative Cooling
2017
Climate Change represents a priority, due to the large variety of implications and importance that it has reached throughout the last decades. In an effort to address this global and local challenge and in order to restrict temperature rise to 2 °C over the next century, it will need to address this topic from several angles, as confirmed by the last COP meetings in Paris and in Marrakech. In this context, the paper presents the modelling and assessment of ventilative cooling applicability in the future of the Mediteranean area under the effects of climate change. Results show that natural ventilation will continue to be of paramount importance in the Mediterranean climate but its highest e…
Caratterizzazione degli edifici non residenziali ad uso scolastico della PA siciliana
2014
La presente relazione finale descrive le ricerche svolte, in seno all’accordo di collaborazione tra l’ENEA e il Dipartimento dell’Energia, ingegneria dell’Informazione e modelli Matematici (DEIM) dell’Università di Palermo. L’accordo di collaborazione è titolato “Caratterizzazione degli edifici scolastici nella Regione Sicilia”. La relazione è suddivisa in due sezioni: la prima, Parte A, illustra lo studio condotto per la caratterizzazione degli edifici non residenziali ad uso scolastico della PA siciliana; la seconda, Parte B, descrive lo stato dell’arte del “Ventilative Cooling” con riferimento particolare ad alcuni casi-studio reali, nel contesto della partecipazione del DEIM alle attivi…
The Role of Natural Ventilative Cooling in NZE Temporary and Emergency Shelters Design: a Mediterranean Case Study
2016
The paper presents a case-study of a pre-fabricated housing module built in Messina (Sicily, Italy) and the assessment of its energy performances under the net zero energy perspective. The potential of ventilative natural cooling application in the case-study is also investigated. Some particular features of the building - the modularity, the prefabrication, the rapidity of assembly, the possibility of being built on disconnected soils and the absence of maintenance - identify an effective use as a temporary housing solution for e.g. workers in proximity of an isolated working place or in emergency situations such as earthquakes and natural disasters. Monitoring studies were performed durin…

2015
Il presente report si inserisce nell’ambito dell’accordo di Collaborazione tra ENEA e il Dipartimento di Energia, Ingegneria dell’informazione e Modelli Matematici (DEIM), per l’attività dal titolo “Sviluppo di piattaforme innovative per il calcolo dell’energia incorporata nell’edilizia e di modelli per la quantificazione del potenziale del ventilative cooling nell’edilizia”, nel contesto del Piano annuale di Realizzazione 2014 del progetto “Sviluppo di modelli per la realizzazione di interventi di efficienza energetica sul patrimonio immobiliare pubblico”. L’attività prevede due linee di ricerca interne, sviluppate, rispettivamente, nelle Parti A e B del presente report: “Sviluppo di piatt…
Natural ventilative cooling in school buildings in Sicily
2016
The paper shows analysis of the impact on thermal comfort of natural ventilation in a nonresidential Mediterranean case-study. Results are based on the EN 15251 approach on adaptive comfort. Different scenarios are proposed, granting an improvement of up to 10% in the number of summer comfort hours.
Ventilative cooling application in Mediterranean buildings: impacts on grid interaction and load match
2016
The concept of load matching refers to the simultaneous occurrence of loads and generation in buildings: it can be increased and optimised with modifications on both the energy demand and generation, but its pre-requisite is to guarantee passive energy efficiency. In the Mediterranean areas, a major challenge in new buildings is the increasing overheating even during mildly hot seasons. Ventilative cooling can be a potential solution to such issues and have an impact on load match in buildings and their grid interaction. The study analyses the potential of ventilative cooling to improve the load match in three different case studies in Italy. Ventilative cooling proved viable in moderately …
