DAYLIGHTING AT THE AUSTIN BERGSTROM INTERNATIONAL AIRPORT TERMINAL AFTER MORE THAN FIVE YEARS OF OPERATION

摘要

Careful attention was placed on the human comfort factors for both the traveler, who spends relatively little time in a certain place, and the airport employees, who occupy certain areas for extended periods of time. The passengers can be classified as occupants moving through the space. Because of their movement and short duration of occupancy in the space, passengers are relatively tolerant of direct sunlight, irregularities in lighting and light levels, and comfort irregularities. Many of the vendors will occupy the space most of the day and some will occupy a single space all operating hours of the terminal facility. Since they occupy the space for prolonged periods, airport and vendor personnel are very concerned with those same issues. It is important to control the quality of light and daylight while providing an environment compatible with human needs and human comfort. It is necessary to carefully address human comfort issues to allow a daylighting scheme to be successful and operate on a long term basis. If employees are subjected to excessive glare, poor lighting control, or excessive temperature fluctuations, their complaints will require the airport staff to close the clearstories, glass walls, and skylights in order to correct the problem. If the clearstories and glass walls are closed, the daylighting and view of the sky from the terminal will be lost. In this case all systems are operating as designed after five years of operation, and all comfort and lighting levels are very close to the predicted levels.
