-Daylighting in buildings refers to the practice of using natural light to illuminate indoor spaces, creating a more desirable environment and potentially reducing energy consumption by 20 to 40 percent.
What are the two categories of daylighting systems?
-Daylighting systems fall into two categories: top lighting, which brings light from the top of a building, and side lighting, which lets daylight in through windows or other openings on the sides of the building.
How does a top light system work?
-A top light system uses skylights to bring natural light into the building from above, providing uniform lighting on horizontal surfaces and walls, similar to electric lighting.
What are some examples of side lighting systems?
-Side lighting systems include windows or other side openings that allow natural light to enter a building from the sides.
Why is a top light system generally more effective than a side light system?
-Top light systems are more effective because they provide uniform lighting from above, whereas side light systems may not create evenly lit workspaces and allow less light to penetrate deeper into the building.
What are the challenges of using side light systems?
-Side light systems may not provide uniform lighting, and occupants often need window treatments, such as shades or blinds, to prevent glare. Additionally, daylight may not penetrate as deeply into the building as with top lighting.

💡Daylighting

Daylighting refers to the use of natural light to illuminate the interior spaces of a building. In the video, it is highlighted as a technique that creates a more desirable indoor environment while reducing energy consumption by 20-40%. The concept is central to the video's theme, as it discusses methods to maximize natural light in buildings.

💡Top Light System

A top light system is a daylighting technique where natural light enters the building from the top, usually through skylights. The video explains how this system can create uniform lighting similar to electric lighting and is easier to implement effectively compared to side lighting systems.

💡Side Light System

A side light system allows daylight to enter a building through windows or other openings on the sides. The video contrasts this with the top light system, noting that side lighting may not provide uniform lighting across workspaces and requires window treatments like shades or blinds to manage glare.

💡Building Orientation

Building orientation refers to the positioning of a building in relation to the sun. This is a key factor in effective daylighting because it influences how much natural light enters the building. The video lists building orientation as the first passive daylighting technique, emphasizing its importance in harvesting natural light.

💡Windows

Windows are essential components in a side light system, allowing natural light to penetrate indoor spaces. The video mentions windows as the second passive daylighting technique, emphasizing their role in letting daylight into buildings and the need for managing light through treatments like blinds.

💡Skylights

Skylights are windows installed on the roof of a building to allow sunlight to enter from above. Mentioned as the third passive daylighting technique, skylights are part of the top light system, which is described as more efficient in distributing light evenly throughout a space.

💡Light Shelves

Light shelves are horizontal surfaces that reflect natural light deeper into a building’s interior. As the fifth passive daylighting technique mentioned in the video, they help enhance the effectiveness of side light systems by distributing light more evenly across spaces.

💡Solar Tubes

Solar tubes, also known as tubular skylights, are devices that capture sunlight and channel it into a building. They are the sixth passive daylighting technique discussed in the video and are part of the top light system, helping to bring daylight into areas without direct access to windows or skylights.
