The goal of this work is to evaluate and to give evidence to innovative and sustainable technologies applied in the construction industry to carry out self-sufficient energy and to use the surplus energy for the production of hydrogen vector. An architectural integration design along with high technological systems is performed. The intermittency of renewable energy sources along with climatic conditions dependency imposes to store the energy produced, since it is clean and having a big calorific value: the hydrogen vector is currently the better energy carrier. The energy to obtain hydrogen by dissociation of water is supplied by a photovoltaic (PV) system. Through the computations of the annual energy balance between building's demand and supply energy, it is shown that the extra energy produced by the solar generation system is used also for the hydrogen sustainable mobility. The renewable systems, model's design and case study are tackled for the bigger one of the Dodecanese islands in the South Aegean Sea: Rhodes (Rodos). The Zero energy building's integrative design-based approach, applied to the Hotel Buildings type industry is targeted to have new hotels buildings, in the Mediterranean typical warm climate, with zero energy consumption. The designers, authors of this work, have studied a real case or pilot project of an hotel, in the resort formula, suitable to the Greek landscape, showcasing technologies and innovations supporting environmental sustainability, energy efficiency, use of renewable energy, electricity storage by fuel cells that are tools particularly applicable to hotel facility [1]. The feasibility of this case study or pilot project is aligned jointly to the target of Zero Emission and Energy Efficiency EU Policy, as imposed by EU Directives. The strategic position of Rhodes in a geographical point full of sun and wind renewable energy power, enables to ensure the clean energy production, the current interesting development of the hydrogen as energy vector in the buildings [2] and also to satisfy the demand of tourists' accommodation by having at the same time zero energy costs. Moreover, the presence in the island of the best example worldwide of ancient and sustainable built environment (UNESCO World Heritage site), represents also the best motivation to give witness there of a zero impact environmental urban development through the adoption of these achieved scientific results for a major success of Zero Energy Buildings.G.

“…So, reducing the energy consumption, recycling or composting food scraps is argued by Bowe (2005), Bruns (2000), Chen, Legrand, and Sloan (2005), Dodd, Hoover, and Revilla (2001), Kallbekken and Saelen (2013), Karagiorgas et al (2006), Pirani and Arafat (2014), Radwan, Jones, and Minoli (2012), Lu, Wei, Zhang, Kong, and Wu (2012) and Xin, Lu, Zhu, and Wu (2012). Furthermore, hotels have noticed the benefits of improving environmental performance generally by reducing operational costs (Forbes, 2001;Kirk, 1998), sustaining a competitive advantage or increased demand for eco-friendly hotels (Bohdanowicz, 2005a(Bohdanowicz, , 2005bLe, Hollenhorst, Harris, McLaughlin, & Shook, 2006;Vazques, Santos, & Alvarez, 2001).…”

The boom of the tourism industry has led to a huge interest in investing largely in hotel lodgings. Tourists have become aware and started considering new and far from ordinary tourist issues, like environmental protection, waste treatment measures, energy efficiency, renewable energy, green-house gas emissions, etc. The aims of the study are three-fold: (i) to assess the application of energy efficiency practices in the hotel industry; (ii) to explore the determinants of energy consumption; and (iii) to pose valuable recommendations for boosting development of eco-friendly hotels. The research was conducted in Macedonia for the purpose of identifying the impacts of several factors of managing environmental protection practices, in the first line by measuring their current level of influence. The data were obtained by an online survey conducted among managers of three-, four-and five-star hotels and processed by descriptive statistics. The results showed that managers have high positive perceptions on environmental protection issues and pose high awareness of the benefits produced by this concept, thus supporting the European environmental impact assessment regulation. The study recommends new approaches in challenging the hotel industry to decrease the operating costs and suggests that managers are in need for better understanding of the importance of energy efficiency.

“…The use of renewable energies in hotels has been reported by Karagiorgas et al , 2006. The authors stated that during the implementation of the project HOTRES they investigated the use of five renewable energy technologies including solar thermal, solar passive, solar PV, biomass and geothermal energy in hotels.…”

The energy analysis of five summer operating hotels in Crete, Greece was implemented and their average annual energy consumption has been estimated at 149 KWh/m 2 and 19.4 KWh/p.n.s. Their average annual CO2 emissions due to energy use have also been estimated at 12.1 kg CO2/p.n.s.. Hotels in Crete utilize various renewable energy technologies with solar thermal energy being the most widely used. Apart from solar thermal energy, solar cooling, passive solar, solar-PV, solid biomass burning and low enthalpy geothermal energy with heat pumps have also been used in various cases. Since some of these technologies are currently cost effective having at the same time many environmental benefits , it is expected that in the future renewable energy technologies will have more applications in providing heat , cooling and electricity in hotels in Crete. Use of various renewable energy technologies in hotels could result in zeroing their CO2 emissions due to the energy use in them. The Greek government currently subsidizes the use of energy saving and renewable energy technologies in hotels aiming in reducing their high energy consumption and the use of the polluting fossil fuels in them.
