Environmental assessment of light well in high-rise apartment building

A growing number of high-rise apartment buildings each with a light well in the center of them are designed in accordance with the structural design and planning for the last 10 years in Japan. This light well is defined as an intermediate space between outdoor and indoor. The questionnaire surveys to four apartment buildings that have different sizes of the light well were conducted to make clear the occupants’ evaluation about the actual environmental conditions. As a result, the environment of light well is almost clearly satisfied except for some matters.
