Lighting with Roof Monitors
In terms of Energy Savings, day-lighting is one of the few initiatives that has a significant impact. These roof monitors allowed sunlight into the 2-story building through vertical south-facing glass, which was then controlled by the calculated placement of baffles so that direct sunlight was never a problem. The monitors are about 15' on a side and slope down from a 7' high point. There were open areas in the second floor to allow sunlight to reach the first floor.
The glass in the roof monitors faced south to get the maximum amount of sunlight into the building all day long in a way that could be controlled. The monitors allowed that to happen in a way that skylights could not.
This project was built in 1997 by a Dutch-owned candy company that had taken on the challenge of becoming sustainable by 2004. They were bought by an Italian candy company before achieving the goal.
