Introduction
Hotel industry constitutes one of the main pillars of the tourism sector. Graci and Dodds (2008) mentioned that resource intensive and frequently inefficient systems and operational routines applied in the sector result in considerable environmental impact and indicate an urgent need for more environmentally sound practices and products in the hotel industry.
Analysing the interest and attitude of the companies regarding the environment, Font (2001) classifies the companies in seven categories: the conservationists (they internalise environmental costs on a constantly evolutionist basis, because they understand the dynamics of the phenomena associated with the environment, and they do not use performance in the field of environment as a promotional instrument, because it would generate a surplus of demand, which is not always desired); the leaders (companies who establish environmental standards in the same way as the conservationists, however, as opposed to the latter, they use environmental performances as a promotional instrument); the distractors (they rather use the principle “I can do” than “I must do”, and they wish to be perceived as green by focusing on the elements which are easy to perform in the field of the environment); the compliers (they consider environmental regulations as an obstacle in tourism development, the environment not being a priority for them, so that the management deals with it only tangentially); the opportunists (they use the environmental aspects with marketing purposes, operating minor modifications in planning the resources and the management by observing the basic legislation regarding the environment, and they express their interest towards the environment within the mission and the purpose of their activity, which is also promoted by promotion tactics, even if there is no strong basis); the skivers (opportunist companies who, with the purpose of maximising their profit, they ignore elementary responsibilities towards the environment by not observing the legislation, and they also do not signal environmental problems); the cowboys (similar to “the skivers”, they promote their tourist products as based on nature, without proving a respectful behaviour towards the environment and the resources used, an attitude easy to approach in tourism compared to other fields, due to the differences among destinations and tourists’ education).
Research targeted at resource consumption in tourist accommodation establishments is, however, sparse. This is not satisfactory given that these establishments are high resource consumers, with tourism accommodation having one of the highest environmental impacts of all subsectors in the tourism sector. (Font, Elgammal and Lamond, 2017; Kasim, 2009)
- Many studies have emphasized the fact that hotel industry is a high-energy intensive and polluting sector (Cottella, 2011; Bohdanowicz, 2005; Ragab and Meis, 2016; Revilla, Dodd and Hoover, 2001, Vellecco and Mancino, 2010). It has been observed that a hotel produces between 160 and 200 kg of carbon dioxide (CO2) per square meter in order to generate electricity, heating or cooling, in dependence to the type of fuel used. In the case of European hotels, yearly energy consumption is of 39 twh (terawatts per hour) and the emissions are responsible for approximately 13.6 megatons of CO2. Additionally, tourists consume between 170 and 440 liters of water per day and each tourist produces about one kg of daily waste, of which no more than 60% is recyclable (Bohdanowicz, 2005).

- Kelly and Williams (2007) mentioned that hotels use substantial amount of energy and are one of the most energy intensive facilities with correspondingly high energy costs. They are ranked among the top five in terms of energy consumption in the tertiary building sector (minor only to food services and sales, health care and certain types of offices).
According to Bohdanowicz and Martinac (2007), a certain level of activity in the area of reducing resource use has been observed for quite some time but the motivation for this was related to cost-benefit issues rather than the environment. Furthermore, most of the initiatives are still considered to be best practice case studies and not daily routines. The constantly increasing prices of basic commodities, such as energy resources and water, encourage the implementation of energy and water efficiency and conservation measures in hotel facilities.
Research Methodology
The purpose of this research is to identify the good practices to achieve the reduction of energy consumption, which could represent an important factor for cost savings. These good practices are implemented in the hotels located in north-east of Italy and Romania, too.
The objectives of the research aim to identify the measures undertaken by hotel managers regarding reduction of energy consumption through improving the energetic efficiency, using alternative sources of energy, and also by paying more attention to the lighting.
The hypothesis at the basis of this research is that good practices regarding reduction of energy consumption represent an important factor for cost savings.
Regarding the research method, we chose research through enquiry, because it assures a higher flexibility, and the data and information are obtained quicker than by other methods (Zaiţ and Spalanzani, 2006).
The sampling included the establishment of the unit to be researched – hotels located in the north-east of Italy and Romania:
- size of the sample – 43 tourist units (Italy) and 49 tourists units (Romania).
- selection procedure – we chose a non-random method, based on accessibility (the sample includes all tourist units, and all managers, respectively, who accepted to participate in the respective research, because one of the limits of the research is the fact that some hotel managers refused to participate).
At the same stage we also dealt with the preliminary data systematisation and processing with the help of SPSS 23 programme.
Research Results
The reduction of energy consumption can be realised by improving the energetic efficiency, using alternative sources of energy, and also by paying more attention to the lighting.
In the following we will present the good practices for achieving the reduction of energy consumption according to the objectives. The situation obtained after processing the data is presented in the following tables (table no. 1-3).
Improvement of Energetic Efficiency
Table 1: Good practices concerning the reduction of energy consumption
Source: Authors; Data obtained in SPSS
From the analysis of the table no.1 and of the figure no.1 above, both in Romania and in Italy a great attention is paid to the reduction of energy consumption by the improvement of energetic efficiency. Consequently, the monitoring of the energy consumption is constantly realised in 46.9% of the Romanian hotels, and in 74.4 % of the Italian ones, the equipment is well maintained, and the energy consuming sources are turned off when they are not in use – in 75.5% of the cases in Romania, and in 95.3% in Italy. Also, in over 79% of the hotels investigated, energetically efficient heating-ventilation systems are installed in over 50% of the Romanian hotels, and in 90% of the Italian ones heating is controlled by thermostat, and over 50% of the hotels investigated are thermally isolated.
Use of alternative energy sources

Source: Authors; Data obtained in SPSS
The use of alternative sources of energy is practised in neither of the Romanian hotels from our sample, as compared to the Italian ones, where in 23.3% of the hotels the photovoltaic solar systems are used, in 14% the geothermal energy is used (the area of our sample being rich in geothermal sources), and in 18.6% of the hotels the alternative energy is delivered by a provider with an active policy in the field of alternative sources of energy.
Lighting
Table 3: Good practices concerning the reduction of energy consumption
Source: Authors; Data obtained in SPSS
The reduction of energy consumption can be obtained by the maximum use of natural light, which happens in 93.9% of the Romanian hotels, and in 83.7% of the Italian ones, the use of energetically efficient lighting devices, found in over 75% of the Romanian hotels, and in over 90% of the Italian ones, as well as by the installation of some motion detectors, temporisers, or potentiometers existing in almost all the Italian hotels, and in over 50% of the Romanian ones.
For a clearer emphasising of the results obtained, we also realised the graphical presentation (figure no. 1).

At the same time, the managers of these hotels are interested in adopting the good practices to achieve cost savings.
Testing the Hypothesis
The hypothesis was tested using a non-parametric test – Binomial Test, a procedure used to validate hypotheses regarding one variable with binomial distribution, which can have only two values. For the variables taken into account we calculate the frequencies of appearance of each of the two values, and based on them we calculate the mean, standard deviation. In a few words, Binomial Test is used to compare a proportion with a specified value. By using the Binomial Test, we wanted to verify if the proportion of one of the two groups presented in the table above significantly differed from 0.50. The sum of the proportions and of the probability of appearance of the two values being one, the probability for any value is 0.50. Regarding our hypothesis:

a Based-on Z Approximation.
Source: Authors; Data obtained in SPSS
The data obtained show that the proportion seen in the sample is 78%, and the proportion specified is 50%. The Sig. value associated to the test is lower than 0.01, so we can conclude, with a confidence of 99%, that the null hypothesis is rejected, and the alternative hypothesis is confirmed. According to this hypothesis, good practices for reducing energy consumption in hotel industry represent an important factor for cost savings.
Conclusions
Hotels consume substantial quantity of energy, water and other non-durable products, thus provoking significant environmental impacts. On the other hand, they rely on clean nature and unpolluted environment as a core value for hotel industry. Tourists more often abandon tourism destinations in poor environmental condition and trace for hotels with eco label, eco certificate and certificate for energy efficiency. Consequently, hotel industry is becoming increasingly environmentally responsible by taking care of energy efficiency.
Due to the fact that clean and well-preserved environment is one of the main preconditions for high quality service generally in the hospitality-oriented facility, one may conclude the dependent nature of the hotel development. Most likely, the energy demand will continue growing in the future, so energy planning and use of renewable sources as energy supply alternatives may be a solution for sustainable development.
The research conducted in the hotels of Italy and Romania highlighted that most of the environmental practices are implemented especially by the management of the Italian hotels, where hotel managers seem to be much more aware of the seriousness of the environmental problems, and the necessity to adopt measures for their improvement, while in the Romanian hotels they are less present.
Consequently, believe that by this research we managed to identify the degree of involvement of the managers from Italian and Romanian hotel industry in the reducing of energy consumption and we highlighted the good environmental practices adopted in hotel industry.
It would be interesting to see also the costs generated by the application of such measures, or the savings we could make in time. They could be future directions of research.
