Protein supplements consumption: a comparative study between the city centre and the suburbs of Palermo, Italy
2014
Background: Protein supplements are extensively used among commercial gym users and athletes. Although demographic information amongst such consumption has been poorly investigated. The aim of this study is to compare protein supplement consumption in commercial gym users, both from the city centre and the suburbs of Palermo, Italy. Methods: A face-to-face questionnaire has been administered to 561 subjects. 207 from the city centre (CC) and 354 from the suburbs (SB) of Palermo, Italy. Protein supplement consumption, frequency of use and association with other dietary supplements has been investigated. Subsequently frequency distribution has been used for demographic assessment. Results: 30…
Forecasting Electricity Consumption and Production in Smart Homes through Statistical Methods
2022
Abstract Over the last years, a steady increase in both domestic electricity consumption and in the adoption of personal clean energy production systems has been observed worldwide. By analyzing energy consumption and production on photovoltaic panels mounted in a house, this work focuses on finding patterns in electrical energy consumption and devising a predictive model. Our goal is to find an accurate method to predict electrical energy consumption and production. Being able to anticipate how consumers will use energy in the near future, homeowners, companies and governments may optimize their behavior and the import and export of electricity. We evaluated the ARIMA and TBATS statistical…
The role of the building sector for reducing energy consumption and greenhouse gases: An Italian case study
2013
The paper presents one of the first Italian experiences assessing the effectiveness of sustainable production and consumption strategies. The authors developed an energy and environmental extended input–output model, combined with the life cycle assessment, to analyse the role of the building sector in the reduction of Italian energy consumption and CO2 emissions. In detail, the model allows to assess the energy and environmental benefits arising from the Italian tax deduction policy for energy retrofit actions of buildings. Moreover, the authors defined an original model to assess the indirect rebound effect caused by the energy retrofit actions. The outcomes of the research point out that…
Application of the Structural Decomposition Analysis to assess the indirect energy consumption and air emission changes related to Italian households…
2012
Abstract The design of sustainable production and consumption strategies and the assessment of implemented actions require to identify the driving forces that influence the trend of energy consumption and environmental impacts. For this purpose, the Structural Decomposition Analysis (SDA) was developed as a suitable methodology to analyse the driving forces of the changes in economic, energy and environmental indicators. The paper presents one of the first Italian studies that apply an energy and environmental extended input–output model, opportunely shaped to the examined context, combined with SDA. In detail, it aims at: (1) investigating the energy use and the air emissions arisen from t…
A Case-Study of Green Roof Monitoring: The Building of Council for Agricultural Research and Economics in Bagheria, (Italy)
2018
The energy saving in building goes on as an important challenge in the policy of Developed Countries. While the issue of energy building efficiency in heating season has deeply been investigated for a long time, the issue of energy building efficiency in cooling season is relatively recent. Moreover, considering the increase of electric consumption for air-conditioning in summer, mainly due to the growing quality of life, the research of technologies for reducing energy building consumption during this season becomes essential. The green roof represents a technology useful to reduce the energy consumption during the cooling season. In this work the authors report the results of a monitoring…
Perceived-Value-driven Optimization of Energy Consumption in Smart Homes
2020
Residential energy consumption has been rising rapidly during the last few decades. Several research efforts have been made to reduce residential energy consumption, including demand response and smart residential environments. However, recent research has shown that these approaches may actually cause an increase in the overall consumption, due to the complex psychological processes that occur when human users interact with these energy management systems. In this article, using an interdisciplinary approach, we introduce a perceived-value driven framework for energy management in smart residential environments that considers how users perceive values of different appliances and how the us…
Alcohol consumption in Spain and its economic cost: A mathematical modeling approach
2010
In this paper, a mathematical model for alcohol consumption in Spanish population is proposed. Its parameters are estimated by fitting the model to real data from Spanish Ministry of Health. Predictions about the future behavior of the alcohol consumption in Spain are presented using this model. Results are applied to estimate the economic costs (sanitary and non-sanitary) assumed by Spanish society that are derived from this consumption.
Monitoring resource consumption and anthropogenic substances in the EU and Latvia
2011
PurposeThe aim of this paper is to assess how the indicator sets presently used to monitor sustainable development in the European Union (EU) and Latvia reflect resource consumption and the production and use of anthropogenic substances.Design/methodology/approachThe study was conducted by analyzing different sources as well as statistical information on development character in Latvia and human impact at first in respect to use of chemicals.FindingsMany of the analyzed sustainable development indicators related to resource consumption interpret a reduction in consumption as a negative phenomena and thus contradictory to sustainability. The only relevant EU and Latvian indicator related to …
Machine learning methods to forecast temperature in buildings
2013
Efficient management of energy in buildings saves a very important amount of resources (both economic and technological). As a consequence, there is a very active research in this field. One of the keys of energy management is the prediction of the variables that directly affect building energy consumption and personal comfort. Among these variables, one can highlight the temperature in each room of a building. In this work we apply different machine learning techniques along with other classical ones for predicting the temperatures in different rooms. The obtained results demonstrate the validity of these techniques for predicting temperatures and, therefore, for the establishment of optim…
Electricity Consumption Analysis of Tertiary Buildings: An Empirical Approach for Two University Campuses
2020
An empirical approach for the analysis of energy consumption of existing buildings of the tertiary sector is presented in this study. It allowed the organization and management of large amounts of data according to different timeframes and helped to focus on leading issues about energy uses, and dealt with compatibility with tariff structure. The analysis method, which implied a powerful graphical representation of the results, allowed us to detect critical issues in electricity energy management for public buildings and improve their energy performance. Furthermore, the authors proposed a set of electricity consumption indexes (ECIs) that gave useful insight into the main hotspots. The bas…
