green index is refer how the main contractor manage the site and how is the Architect idea for implementation.
usage of aluminium formwork = eliminate use of timber formwork, no more timber and wastage on site
recycling of construction debrish on site = glass, plastic, metal, timber and etc
paperless administration = all using email, integrated project system, server for filing.
collection and reuse of rain water for construction works.
block stone as partition wall = not depending clay brick which requires natural resources and extreme energy for burning
very cool features but costly to implement.
