Natural vs Artificial Light: The Skylight Debate for Terminal Buildings.
Skylights are often seen as a great way to introduce natural light into a terminal building. However, there is an ongoing debate about whether skylights are the best solution compared to artificial light sources. In this article, we will explore both sides of the argument and provide insights into the reasoning behind each position.
The Argument for Skylights.
Proponents of skylights argue that natural light is beneficial for both passengers and airport employees. Exposure to natural light has been shown to improve mood, reduce stress and enhance productivity. Additionally, it can help regulate the body’s circadian rhythm which leads to better sleep patterns and overall health. This is particularly important for flight crews and air traffic controllers who work long and irregular hours.
Skylights also offer an opportunity to save on energy costs by reducing the need for artificial light. This is especially true for airports that operate during the day when natural light is abundant. Furthermore, it adds an aesthetic value to a building by creating a sense of openness and connection to the outside world.
The Argument for Artificial Light.
However, not everyone agrees that skylights are the answer. One argument against skylights is that they can lead to excessive solar gain and heat loss in some climates. In colder climates, for example, skylights can contribute to energy loss and increased heating costs. Similarly, in warmer climates, the sun’s direct rays can create hotspots and increase cooling costs.
Additionally, skylights require regular maintenance to prevent leaks and damage from weather and aging. This can add to the cost of building maintenance and increase the risk of potential delays and disruptions.
Another argument against skylights is that they may not always provide consistent lighting throughout the day. This is due to changes in weather conditions and the angle of the sun’s rays. Artificial light, on the other hand, can be controlled and adjusted to provide consistent lighting levels regardless of external factors.
Conclusion.
In summary, the debate over skylights in terminal buildings is not a clear-cut issue. While they offer many benefits, such as improved mood, energy savings and an aesthetic appeal, they also have downsides. Skylights can lead to increased heating and cooling costs, require regular maintenance, and may not provide consistent lighting. Ultimately, the decision between natural and artificial light sources will depend on various factors such as climate, building design, and budget constraints.
