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.

“…The air temperature by itself is not fully sufficient to reflect the thermal comfort of occupants. The effects of thermal radiation on occupant comfort is important and must be integrated [64][65][66]. This could be achieved by utilizing the mean radiant temperature (MRT) [67,68].…”

Abstract:Energy performance of buildings has attracted much attention among building physicists and engineers worldwide. The effects of building heating; ventilation; and air conditioning (HVAC) systems' design upgrade on the building energy performance are the focus of the current study. The adopted HVAC system consisted of chilled ceiling and chilled beam systems served by a centrifugal water chiller. An energy simulation study was undertaken in accordance with the national Australian built environment rating system-rules for collecting and using data. A three-dimensional simulation study was carried out utilizing the virtual environment-integrated environmental solutions software. Results from the current study have shown the importance of utilizing energy-efficient HVAC systems and HVAC strategies for achieving a high building energy star rating. Recommended strategies in order to achieve the nominated star rating; as predicted by the simulation analysis; were presented. Moreover; the effects of solar radiation inside the building atrium were significant; which cannot be overcome by simply installing a low shading coefficient glazing type at the atrium skylight. In addition to providing chilled ceiling technology; a high efficiency chiller and low energy lighting; it is recommended that the building be well tuned during the commissioning period. The current approach could be extended to accommodate higher energy ratings of commercial buildings at different locations worldwide.

The Italian hospitals are housed in old buildings, some statistics report refers which they have should be about of fifty years old. Recently new structures were built, but the trend is that over restructure and/or redevelop existing buildings, making by a cost-benefit analysis that supports this choice. The Italian construction industry covers the most part of the national energy requirements, and the hospital have a big energy request because the buildings of different areas with different destinations represent the major demand of the needed energy sector.Hospitals must observe the same climate conditions, although the average fuel consumption is three times more than the average values of the residential construction sector.The energy demand in this sector have been used in different way: air conditioning in summer and winter, ventilation, environments lighting, domestic hot water, steam generation for sterilization and humidification, as well as the request by the kitchens, laundries, domestic transport, computers, diagnostic and therapeutic devices, etc.Furthermore, this demand should be absolutely guaranteed, in particular for the thermal and electrical installations, for everyday of the year.The complexity of the equipment used and the regulatory compliance in terms of temperature, humidity and air flow, it could lead considerable consumption, increasing the difficulty of management plants.However, the hospital buildings have a large energy savings potential, which could be achieved improving efficiency of building-plant systems, management of energy.The air conditioning systems of the hospitalization facility should meet specific technical and functional requirements in order to ensure compliance with the temperature-humidity requirements of itself.The regulatory and legislative system should pay attention to the standards and the eligibility criteria for these environments, such as the rooms to be used as hospital stays, providing a strategy to obtain higher values of comfort and safety.The ABSTRACTIn 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 areasof flows and air changes within i...
