This month we will do a deep dive into a real Grails project / product of fairly high sophistication.
EnergyScoreCards is the application I work on. It's a data platform and BI tool for helping organizations make decision around energy efficiency of residential buildings.
It's been built from the ground up using Grails for the last two years with a team that now totals five (and hiring). It's actually three different products that share the same database backend. We are currently on Grails 1.3.6 and use a variety of standard plugins.
