Coming from someone in the building industry this is a huge ( trump HUGE ) industry.Vancouver is a city hell bent on green energy and are mandating all kinds of energy saving requirements in their building codes.I will bring this to the attention of some of the major builders in the city to review.This is far bigger than displays and just goes to show we dont anything about the 40 ndas they have and when something from any industry could pop up.Its a good day !
