Abstract
Software design patterns are widely used in software engineering to enhance productivity and maintainability.However, recent empirical studies revealed the high energy overhead in these patterns. Our vision is to automatically detect and transform design patterns during compilation for better energy efficiency without impacting existing coding practices. In this paper, we propose compiler transformations for two design patterns, Observer and Decorator, and perform an initial evaluation of their energy efficiency.

Recent studies [3], [4], [5] found that some, not all, design patterns negatively impact energy consumption (up to 712% on embedded hardware).
In this paper, we study the Observer and Decorator patterns that consistently performed poorly across all empirical studies, including ours. We propose energy efficient transformations for programs with these design patterns. The program transformations are to be carried out during the compilation stage.
In [3], the authors compared the energy consumption of 6 design patterns on mobile phones. They found a high overhead for the Prototype, Decorator and Factory design patterns (33%, 133%, and 15.9% overhead, respectively).

The authors in [4] compared the energy consumption of 3 design patterns. Their results show a negligible energy overhead for the Factory and Adapter patterns, and around 44% energy overhead for the Observer pattern.

Finally, Sahin et al. studied the energy consumption of 15 design patterns in [5]. Their results show a high energy overhead for the Factory, Decorator and Observer patterns (712%, 21.55%, and 62%, respectively).

As can be seen in Figure 1, the patterns with high energy overhead (>10%) are Observer (30.63%), Decorator (12.24%) and Mediator (26.61%).
In this paper, we present an approach to improve the energy efficiency of software by optimising design patterns automatically at compile time. We explored simple transformations for the Observer and Decorator patterns and found energy reductions in the range of 4.32% to 25.47%.
