RADIANCE+ (softwaRe behAvior DesIgn And eNergy Consumption assEssment) is a webapp tool that facilitates green software design with a model driven approach. Users can design atomic fragments of software called "profiles". Profiles use the "Behavior Based Consumption Profile (BBCP) Domain-Specific Modeling Language", which is a modeling language that we have created to mimic the evolution of software usage through time (we call this "diachronic software behavior"). Profiles can be later agglomerated in "collections", which can represent full applications or individual components. There are several features in RADIANCE that make it unique.
