How Skylights Can Improve Energy Efficiency 1

Natural Lighting and Energy Efficiency

When it comes to energy efficiency in buildings, finding ways to reduce reliance on artificial lighting is a key factor. Skylights, which are windows installed on rooftops, offer a natural solution that can significantly improve energy efficiency in both residential and commercial spaces. By harnessing natural light, skylights not only reduce the need for artificial lighting during the day but also provide additional benefits such as improved productivity, better health, and reduced energy costs. Dive deeper into the topic and uncover extra information in this specially selected external resource. Learn this, explore new details and perspectives about the subject covered in the article.

Benefits of Skylights

1. Energy Savings: By utilizing natural sunlight, skylights can help reduce electricity consumption during daylight hours. When properly positioned and installed, skylights allow ample natural light to enter a space, reducing the need for artificial lighting and resulting in lower energy bills.

2. Mental and Physical Health: Sunlight is known to have positive effects on mental and physical well-being. Sunlight exposure boosts vitamin D levels, which aids in calcium absorption and bone health. Additionally, natural light can improve mood, increase productivity, and reduce the symptoms of conditions such as depression and seasonal affective disorder (SAD).

3. Aesthetics and Visual Appeal: Skylights add a touch of elegance and aesthetic charm to any space. They create an open, airy feeling by bringing natural light into rooms, making them brighter and visually more appealing. This can significantly enhance the overall ambiance and comfort of a space, improving the quality of living or working environments.

The Role of Skylights in Energy Efficiency

1. Daylight Harvesting: Skylights allow natural light to penetrate deep into buildings, reducing the need for electric lighting and providing occupants with a connection to the outdoors. With proper design and placement, skylights can effectively illuminate larger areas, reducing the need for artificial lighting during daylight hours.

2. Reduced Energy Consumption: By relying on natural light during the day, skylights can significantly reduce energy consumption and associated costs. According to studies, the use of skylights and daylighting strategies can result in energy savings of up to 80% for lighting purposes. This reduction in energy usage also contributes to a decrease in carbon emissions and helps combat climate change.

3. Improved Thermal Performance: Skylights can also play a role in improving the thermal performance of a building. The right skylight design and materials can help prevent unwanted heat gain in the summer and heat loss in the winter. Properly insulated skylights can enhance the overall energy efficiency of a space by reducing the need for additional heating or cooling.

Innovations in Skylight Technology

1. Energy-Efficient Glazing: Advanced glazing technologies have greatly improved the energy efficiency of modern skylights. Low-emissivity (Low-E) coatings, for example, help to minimize heat transfer while allowing natural light to pass through. These coatings reduce glare and improve thermal insulation, making skylights more efficient in controlling heat gain and loss.

2. Automated Control Systems: Innovations in skylight control systems have made it easier to optimize energy efficiency. Automated systems allow skylights to be programmed to open and close according to temperature, humidity, and daylight levels. This ensures that skylights provide natural ventilation and light when needed while also preventing unnecessary heat gain or loss.


Skylights are a versatile and effective solution for improving energy efficiency in buildings. By harnessing natural light, skylights reduce the reliance on artificial lighting, resulting in energy savings, improved health, and an aesthetically pleasing environment. With advancements in glazing and control technologies, skylights continue to evolve as a sustainable and energy-efficient lighting solution for both residential and commercial spaces.
