KaliTerre is a French company founded in 2010 that provides eco-design training, consulting, and software called Greenspector to help companies detect resource-intensive patterns in source code. Greenspector analyzes code based on 250 eco-design rules, proposes practices to correct issues, and provides metrics on estimated resource savings. It is available both as a cloud-based SaaS and a plugin for the Eclipse IDE. Customers range from small startups to large enterprises seeking to extend hardware lifetime and reduce IT costs through more efficient software.

10. Eco-design for software: an obvious!
An infinite IT world :
Big data
Very High Definition
Faster interactivity
Mobility
An important rise in the number of internet users
and services
The race for more powerful hardware, more thrifty is “the default
solution”
Eco-design for software is becoming an obvious
For ecologic and sustainable economic gains

11. Eco-design: Green Software is $Green !
Energy savings
Extending IT equipment life time
Reduce IT costs : less purchase of
equipment, software licenses & space
“Economic scalability” for an increased
load
Profits thanks to the performance, and to
the autonomy on constrained or nomad
systems
Societal responsibility for your IT developers
Giving value on your product or service for
your customers

33. :
8 reasons to do Eco-design for Software with
Greenspector® !
1. Finds on millions lines of codes consuming patterns
2. Brings solutions to correct these codes
3. Rules validated and based on measurement from an independent research
laboratory
4. Multi-language (Java, PHP, JS, CSS, HTML, SQL, C,…)
5. Shows the gains and refactoring time for each rule  helps to decide and to
plan
6. For project manager (management indicators, multi-applications’ view,
reporting, level change over time) & developer (integrated on Eclipse, Sonar)
7. Quick spread into the organization, without technical training nor specific
equipment
8. Scalable in price & to fit all companies 33
