2. INTRODUCTION Effects due to hardware Effects due to software GreenSoft Model Level 1 of Green Model Green Software Life Cycle Level 2 of Green Model Conclusion

3. Effects due to Software Responsible for CO2 emission. Indirect effect on the environment by operating and managing the underlying hardware running it. Software based solutions can monitor and utilize resources efficiently Lack of models and work in the area of computer software

4. GREENSOFT model The model supports all stakeholders from developers to users to create, maintain, and use software in a green fashion. The model comprises many aspects of a software product and organizes them into four parts. The parts include the life cycle of the product being produced, metrics that should be added as an evaluation criteria, procedure models, and recommended tools for developers, purchasers till users. The model addresses the complex sustainability concept and forces it to be integrated into the complex software engineering process in a smooth way. In each life cycle stage, it states the effects of ICT on the product and the environment. This is one of the hardest tasks and is one of the main challenges today in Green Computing

5. Level 1 of Geen Model

6. Green Requirements Engineering

7. Green Designing Engineering

8. Green Testing Engineering Process

9. Level 2 of Green Model

10. Green Analysis Process

11. Green Model

12. Conclusion Its engineering building process from requirements to disposal should be carried out in an energy efficient manner A new green software engineering process should be created to fulfil the constraints of energy efficiency. This will reduce the negative effects of ICT on sustainable development and the environment

13. ANY QUESTIONS??????? ???
