Things to keep in mind when analyzing daylighting in AGi32
Accurate daylight analysis requires using the correct surface designation for exterior, but not interior, surfaces.
The key to accurate daylight analysis using AGi32 is the assignment of the correct surface type designation to glazing and exterior surfaces. Interior surfaces require no special treatment. Daylighting calculations using AGi32 follow several important assumptions:
- AGi32 considers the following daylight components: sunlight, skylight, and light reflected from a “virtual” ground plane.
- Daylight can only be seen by an interior surface (interior of a room or object) after it has passed through a “daylight transition surface.” This is typically daylight transition glass.
- All exterior surfaces must be classified as “daylight exterior surfaces” to accumulate daylight components.
- “Daylight transition surfaces” will consider light reflected only from “daylight exterior surfaces.”
- Daylight models must contain at least one “daylight transition surface” or “daylight exterior surface” in order to compute daylight component.
- The virtual exterior ground surface is automatically assigned a reflectance of 18% (average reflectance of an exterior scene, by Eastman Kodak, circa 1904).
With these ideas in mind, we can create any model, classify all exterior surfaces as “exterior daylight surfaces” and classify all glazing as “daylight transition glass.” All interior surfaces may remain single- or double-sided, as created using the room or object tools, or imported (imported surfaces become objects).

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
