Towards a Green and Sustainable Software

International audienceInformation and Communication Technologies (ICTs) are responsible around 2% of worldwide greenhouse gas emissions [1]. On the other hand, the use of mobile devices (smartphone, tablet, etc.) is continually increasing. Due to the accessibility of the Internet and the cloud computing, users will use more and more software applications which will cause even an increasing effect on gas emission. Thus, an important research question is "how can we reduce or limit the energy consumption related to ICT and, in particular, related to software?" For a long time, proposed solutions focused only on the hardware design, however in recent years the software aspects have also become important. Our first objective is to compare the studies in the research area of energy efficient/green software. Relying on this survey, we will propose a methodology to measure the energy consumed by software at runtime

Governance strategies in sustainable campus using Rasch model

In moving towards sustainability, university needs to establish a good governance strategy which practices to transform a positive sustainable culture toward successful green campus. Howe ver, due to constraint of knowledge and commitment regarding sustainability integration has caused weakness in the implementation of green concept in majority of Malaysian universities. This paper is presents one of the five dimensions of a developed hypot hetical integrated sustainable campus model which is university governance. The university governance dimension consists of 5 constructs and 23 items which are strategies for the university to be complied. These strategies were uncovered using questionnair e survey with 35 selected experts who are currently active in sustainable campus activities and researches. Collected data from this survey was analysed using Rasch method in Winstep software to measure items reliability, separation index, items polarity, item fit and item person map. Results from the analysis indicated that 19 strategies were significant to be implemented. Thus, it provides good information for universities to adopt these sustainable campus strategies in making their campus as a role mode l for a sustainable and conducive living environment

Kick-starting Green Business Process Management – Suitable Modeling Languages and Key Processes for Green Perfomance Mesaurement

In this paper we examine an initial step towards Green Business Process Management. We give insights from a research project with the goal of monitoring and redesigning business processes in an environmentally sustainable manner. Using literature analysis and three case studies we derive suitable languages and software for business process modeling. In addition, we show business processes that can act as key examples for green process monitoring and redesign. The results show that enterprises can build up on process modeling and energy monitoring to become more environmentally sustainable

5Ws of Green and Sustainable Software

: Green and Sustainable Software has emerged as a new and highly active area in the software community. After several years of research and work, we believe that it is now necessary to obtain a general snapshot of how the research in this area is evolving. To do so, we have applied the 5Ws (why, when, who, where, and what), a formula for getting the complete story on a subject. We have therefore carried out a study, using 542 publications related to Green and Sustainable Software research; these were recovered using SCOPUS. The results obtained allow us to conclude that it is important to identify key elements of the research to allow researchers be fully aware of the state of the research on Green and Sustainable Software (why); the study uses papers published between 2000 and the beginning of November 2018 (when); the most prolific authors are mainly from Europe, although the USA is the most active country, Green and Sustainable Software being a very interactive area with a good number of multinational publications (who); the top five keywords related to sustainable aspects are Green Software, Green IT, Software Sustainability, Energy Consumption, and Energy Efficiency (what); finally, as regards the places authors prefer to publish in, there is almost a complete balance between conferences and journals, with a trend towards an increase in the number of publications (where)

Unveiling the Impact of Sustainable Interior Design Criteria on Hotel’s Operational Performance Effectiveness and User’s Hedonic Consumption

Performance effectiveness in the hotel’s operational stage is significant for hotel industry as the industry relies on customer satisfaction towards the service. Fulfilling the customer’s satisfaction and users’ hedonic on the aesthetic appearance, interiors, room decorations, and furnishings is crucial for hotel's operational and facilities management concept. However, awareness the management of tangible interiors and aesthetic performance on sustainable interiors products are still lacking in the hotel's operational performance. This study aims to close the loop between the sustainable interior design (SID) and facilities management, by identifying the criteria of SID relating to hotel’s operational performance and user’s hedonic consumption. A semi-structured interview was carried out this study involving three professionals; architect, interior designer, GBI facilitator, in various green hotels project. The data is analysed using ATLAS.ti9© qualitative software. The findings revealed that there are seven (7) sustainable ID criteria consists of biophilic, energy efficiency, water consumption, health and social flexibility, environmental comfort, ergonomics, and green awareness. This study is significant for the hoteliers in identifying critical elements contributed to the successful performance in hotel’s operational stage using sustainable interiors.

Vegetated roofs as a means of sustainable urban development : a scoping review

Urbanisation affects the water cycle and heat balance in a negative way. Vegetated roofs have the potential to minimise the effects of urbanisation. A scoping review is presented here to examine how vegetated roofs are being evolved as an effective tool of sustainable urban stormwater management and overall urban development. It has been found that research on vegetated roofs has been increasing significantly and it can contribute towards achieving multiple sustainable de-velopment goals (SDGs). It has also been found that the uptake of vegetated roofs has been slow. A lack of regulatory acceptance caused by an absence of experimental data and a subsequent knowledge gap establishing the effectiveness of vegetated roofs are major reasons behind this slow uptake. Future research on vegetated roofs and their subsequent evolutions should put a focus on gathering experimental data towards establishing a performance benchmark for detention, retention and water quality in urban settings. Such data can be utilised towards developing a stand-alone guideline and software for green roof design

Research on the Behavior of Gen Z on Using of Green Tourism: The Role of Knowledge Sharing

Purpose: The main objective of this study is to clarify the role of knowledge sharing about green tourism on tourists’decision to use tourism services.   Theoretical framework: This study applies the theory of planned behavior (TPB) as a basis framework to determine the factors that affect tourists’ decisions.   Design/Methodology/Approach: This study used quantitative research methods with data collected through questionnaires with respondents of young people in Hanoi, Vietnam. The results were 288 valid questionnaires processed with structural equation modeling (SEM) through SPSS and Amos software.   Findings: This study confirms the influence of attitude factors, and perceived behavioral control on Gen Z's decision to use green tourism services. Moreover, the study confirms the role of knowledge sharing about green tourism as an antecedent factor that shapes the mechanism influence of green perception of Gen Z in the relationship between attitude and decision to use green tourism services.   Research, practical & social implications: This study helps administrators have a deeper insight into the importance of knowledge sharing activities in training, recruitment and orienting sustainable development policies towards raising awareness about the goal of building sustainable development. building and developing a green economy in general and the tourism industry in particular.   Originality/Value: This study has shown that knowledge sharing builds and leads to positive attitudes about green tourism services.

THE STUDY OF AIR FLOW MOVEMENT USING GAMBIT AND FLUENT SIMULATION (2D) PROGRAM FOR PASSIVE VENTILATION DESIGN CONCEPT OF LOW RISE BUILDING IN MALAYSIA

Providing adequate natural ventilation would reduce the building cooling load in tropical areas. This regarded as a design moving towards green or sustainable building concept. Driving forces for natural ventilation in those hot and humid countries are basically wind induced actions. This effect depends on the surrounding environment in a dense urban area, where buildings are closely built together. This project is to adapt the green building design concept in Malaysia. Further investigation is to be done especially on air flow movement. The Green Building features were adapted by modifYing the window dimension and proposed the air chimney at the room's ceiling. Some simulations using CFD software (Gambit and Fluent) was done in order to analyze data and to come out with a proper system .The results show that the wind velocity inside the master and single bedroom has increased when the window dimension is increased and the proposed air chimney is provided. Results are useful to provide better ventilation system
