WHAT IS SOFTWARE WITH A SUSTAINABILITY INTENT?

WHAT CHALLENGES DOES IT BRING?

WHAT DO THESE PROJECTS HAVE IN COMMON?

#1: THIS IS WHAT MAKES SOCIETY A BETTER PLACE #2: SOFTWARE IS THERE TO MAKE THE DREAM COME TRUE

[SoSA*] understand what matters: drivers and tradeoffs

Forexample,atGreenITAmsterdamcurrentlyusedfor

•  Topic: Electric Vehicles for City Renewable Energy Supply •  SIAM application: Assess existing 'integration of electric mobility, smart

grids and renewable energy’ practices •  Goal: Develop a framework of experiences and policies where energy and

mobility will work together and not act as different entities based on assessment of existing experiences and practices

•  Topic: Circular design scenarios for Green Data Center campus area •  SIAM application: Assess the possible scenario choices for data center

owners interested in developing a new location at the campus •  Goal: Provide tailored business case input for decision-making and scenario

selection
