Questions and Answers

What is a disadvantage of relying on conventional window space for daylighting, especially during midwinter?

Consistent lighting regardless of the season

Highly directional light with deep shadows (correct)

Even lighting throughout the day

Highly diffused light

How can the issue of deep shadows from highly directional light during midwinter be partially addressed in daylighting?

Increasing direct sunlight exposure

Utilizing more transparent windows

Installing darker curtains

Using light diffusion and reflective internal surfaces (correct)

Why do equatorial-side windows receive direct sunlight on any sunny day of the year?

Because of their design orientation (correct)

Due to artificial lighting systems

Through specialized glass materials

By reflecting sunlight from other surfaces
