The term "Smart" in the last decade has often flanked other words to express a new and intelligent way of living in a modern society where you cannot separate the two synergic aspects: Energy and Sustainability. These latter two aspects flow into the new way of managing an isolated territory that often presents difficulties because of no interactions with the surrounding area; to remedy these difficulties has been developed in recent years the "Smart-Island" project, which involves many European countries and several sponsors. The concept of "SmartIsland" defines a way of life in an isolated environment, such as that of these islands, can solve independently, with the use of renewable and sustainable sources the energy needs of the island, with some projects that take into account the preservation and the wealth of the territory. In this paper, after a brief review of what has been proposed in some islands of the world, it will develop a case study, represented by the island of Favignana, which has particular characteristics in relation to its energy dependence.

In hospitals, the energy demand of the different areas can be divided in form of thermal energy, cooling and electricity. The complexity of the energy system of each structure may be different from hospital to hospital as well as to the volume of manufactured. In fact, the energy demand is closely related to:-health activities that take place in it; -its geographical location; -the structural type and adopted plant The use of different type of energy sources is due to the implementation of different technology options and then to specific operating costs and levels of different issues.In the graphs below (Figure 1 and 2) is shown the values and percentages of annual energy demand required for two different hospitals located in the northern of Italy, respectively: Zucchi Clinic (MB) and the City of Pavia Care Institute (PV) -Reference year 2012.The energy demand for Heating, Ventilation and Air Conditioning (HVAC) is equal to 45% for the first structure and of 69% for the second structure analyzed.It denotes in both cases, that this request always results in a higher percentage than all other requests and in the case of the care institute City of Pavia, the contribution percentage is higher of 50% higher.Taking into consideration the same study, conducted for the Zucchi clinic and the City of Pavia health institution, also ensures that the demand for natural gas (methane gas) for technological uses is particularly relevant to the request for HVAC uses, and then for technological uses. In fact, the following charts (Figure 3 and 4) show that the demand for natural gas is higher in the winter months with a INTERNATIONAL JOURNAL OF HEAT AND TECHNOLOGY ABSTRACTIn hospital, air conditioning and air treatment systems are of great importance both for functional and energetic point of view. In fact, these systems must guarantee the conditions of hygrothermal air quality and comfort for people (patients, staff, visitors), but also meet the operational requirements related to the medical activities in specific environments or departments. In particular, diagnosis and surgical activities request to ensure a high air quality conditions in order to ensure the appropriate environments of asepsis and hygiene [1][2][3]. The aim of this study is to evaluate the possible energy saving solutions to optimize and reduce energy demand [4][5] in the health facilities. Particular attention is focused to the operating theaters, which, because of the type of technological systems used, have a major impact on energy demand the entire healthcare facility.

“…Zone dry-bulb air temperature measurements when used in isolation might not always by suggestive of the actual thermal sensation of the occupants due to all other factors also affecting thermal comfort in building spaces, such as the effect of solar radiation or humidity [9]. In view of this, the effect of solar radiation on thermal comfort has been studied extensively [36,37], while in [38][39][40][41], controllers able to compensate this effect in buildings with Thermally-Activated Building Systems (TABS) were presented. In this paper, we take a wider view on the effect of dominant parameters affecting thermal sensation and suggest that depending on the thermal characteristics of each building, as well as the types of heating and cooling systems, some of these additional factors should be taken into account.…”

Using Thermostats for Indoor Climate Control in Office Buildings: The Effect on Thermal Comfort

et al. 2017

Thermostats are widely used in temperature regulation of indoor spaces and have a direct impact on energy use and occupant thermal comfort. Existing guidelines make recommendations for properly selecting set points to reduce energy use, but there is little or no information regarding the actual achieved thermal comfort of the occupants. While dry-bulb air temperature measured at the thermostat location is sometimes a good proxy, there is less understanding of whether thermal comfort targets are actually met. In this direction, we have defined an experimental simulation protocol involving two office buildings; the buildings have contrasting geometrical and construction characteristics, as well as different building services systems for meeting heating and cooling demands. A parametric analysis is performed for combinations of controlled variables and boundary conditions. In all cases, occupant thermal comfort is estimated using the Fanger index, as defined in ISO 7730. The results of the parametric study suggest that simple bounds on the dry-bulb air temperature are not sufficient to ensure comfort, and in many cases, more detailed considerations taking into account building characteristics, as well as the types of building heating and cooling services are required. The implication is that the calculation or estimation of detailed comfort indices, or even the use of personalised comfort models, is key towards a more human-centric approach to building design and operation.
