La qualità ambientale interna un dominio di analisi in costante aumento poiché le persone tendono a trascorrere il 90% del loro tempo al chiuso. Detto questo, la necessità di monitorare la qualità ambientale interna (QAU) per garantire la soddisfazione degli occupanti è scontata. Un approccio per affrontare questo problema è la post –occupancy evaluation (POE) che combina feedback degli occupanti del luogo oggetto di valutazione e monitoraggio ambientale (ad es. Temperatura, umidità, IAQ, rumore ecc.). Questa tesi di laurea studia l'uso della post –occupancy evaluation, per ottenere una migliore qualità ambientale interna senza compromettere le esigenze di riscaldamento e raffrescamento di un edificio per uffici dell'Università e situato a Milano, Italia. L'obiettivo principale era comprendere innanzitutto il funzionamento dei sensori installati e i possibili parametri che interferiscono con la loro installazione e quindi proporre modi per ottimizzare l'equilibrio tra comfort termico, comfort in termini di CO2 e carichi termici. Scopo di questa tesi è indicare quali azioni possono essere intraprese a partire da lievi modifiche del comportamento degli utenti (ad es. Apertura della finestra nel caso in cui i livelli di CO2 siano elevati) fino a imponenti riorganizzazioni dello spazio come il trasferimento dei mobili in spazi con output più favorevole o diminuendo l'occupazione massima consentita. Tali applicazioni potrebbero fare la differenza se integrate nella progettazione futura degli edifici, poiché la soddisfazione degli occupanti avrà sicuramente ripercussioni non solo sulla produttività degli edifici per uffici, ma anche sul benessere generale.

Abstract
Indoor environmental quality constitutes an ever-increasing domain as people tend to spend 90% of their time indoors. That said, the necessity to monitor indoor environmental quality (IEQ) and interfere accordingly to ensure occupant satisfaction, is for granted. An approach to tackle this issue is post-occupancy evaluation (POE) that combines feedback from the occupants of the place being evaluated and environmental monitoring (e.g. temperature, humidity, IAQ, noise etc.). This master thesis investigates the use of post-occupancy evaluation to achieve better indoor environmental quality without compromising the heating and cooling demands for a University office building located in Milan, Italy. The main objective was to understand first the way the sensors operate and possible parameters that obstruct their correct implementation and then propose ways to optimize the balance between thermal comfort, comfort in terms of CO2 and thermal loads. Goal of this thesis is to indicate measures that can be taken varying from slight users’ behavior modifications (e.g. opening the window in case the CO2 levels are high) to massive space layout re-arrangements such as relocating the furniture in spaces with more favorable output or decreasing the maximum permitted occupancy. Such applications could make the difference if integrated in the future design of buildings as the occupants’ satisfaction realized is sure to be affecting not only the productivity in case of office buildings but also of the general well-being.File | Dimensione | Formato | |
