Abstract
In hospitals, the requirements relating at comfort thermo-hygrometric, lighting and air quality, play a major role and are related, at the characteristics of the building-plant system, and to the activities that take place in it. The climate control of the environments constitutes a major problem in the hospital field, and it has effects not only in the realization of new facilities, but also in the renovations. The systems must be designed and engineered with a full integration with the global project, which is simple in the case of new construction, more difficult in the event of restructuring, since it is necessary to interact with restrictive constraints conditioning, such a distribution of complex and articulated spaces. In design of the systems of a hospital building, two fundamental aspects must be ensured: total control of the thermo-hygrometric parameters (temperature, humidity and air velocity), and the possibility of the control and adjusting -for the single areas-of flows and air changes within individual rooms. The conditioning systems of the hospitals are supposed to represent the state of arts, in terms of technological research and energy savings, maintaining overall the highest level of welfare, for operators and user. In fact, less than half of modern health facilities are newly built and only 34% have been completed after 1971. In addition, from specific regulatory perspective, for air-conditioning systems in hospital buildings, in Italy there is no real legislative/regulatory corpus. Therefore the legislation is very limited, and for the reasons set out above, in this paper will reported the studies carried out at a hospital in the city of Messina, for evaluating the indoor global comfort conditions through the feedback of appropriate quality indices: temperature, humidity and air velocity, lighting and air quality. For the evaluation of hygrothermal comfort conditions is used the model suggested by the ISO 7730 standard.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
