Alder’s FAQ: What is Daylighting – and What is It Not?

Here at Alder’s, we are proud to specialize in providing high-quality daylighting systems designed to enhance interior spaces with the power of natural light. But what exactly is daylighting? And just as importantly, what is it not? In this FAQ-style blog, we’ll break down the fundamentals of daylighting, dispel common myths, and highlight the many benefits of incorporating daylighting strategies into your building design.

What Is Daylighting?

Daylighting refers to the strategic use of natural light to illuminate interior spaces, reducing the need for artificial lighting and minimizing energy use. A well-executed daylighting design considers various factors, including glazing materials, light transmittance, and lighting levels, to create a comfortable and energy-efficient environment.

Some of the key benefits of daylighting include:

• Energy Savings & Efficiency – By reducing reliance on artificial lighting, daylighting can significantly lower electricity costs while decreasing overall energy consumption.
• Enhanced Well-being – Studies have shown that exposure to natural light improves mood, productivity, and overall well-being for building occupants.
• Sustainability – Incorporating daylighting strategies aligns with green building practices, making structures more environmentally friendly.
• Improved Lighting Design – A thoughtful approach to daylighting enhances lighting levels and reduces issues such as glare and heat gain, which can impact comfort and performance.

What Daylighting Is Not…

While the benefits of daylighting can seem clear, it’s essential to differentiate these advantages from common misconceptions. Effective daylighting design requires more than just adding a few windows or skylights—it is a science-backed approach to optimizing natural light.

Here are a few prevailing misunderstandings to consider:

• Not Just Windows & Skylights – Daylighting is not simply about adding a large amount of windows to your existing design. It involves careful planning using specific and tailored daylighting systems, diffusing materials, reflectance, and overhangs to control light transmittance and distribution accordingly.
• Not Uncontrolled Sunlight – Allowing too much direct sunlight into a space without proper diffusion can cause excessive heat gain and glare, making the environment uncomfortable for building occupants. Good daylighting uses shading devices, proper glazing, and daylight redirecting strategies to balance brightness and temperature.
• Not a One-Size-Fits-All Solution – Every building has different daylighting needs. Proper daylighting design considers factors such as building orientation, climate, and interior layout to ensure maximum effectiveness.

Common Misconceptions About Daylighting

“Daylighting Causes Too Much Glare and Heat”

This is a common concern, but effective daylighting strategies prevent excessive brightness and temperature fluctuations. Techniques such as overhangs, diffusing glass, and automated lighting systems help balance direct sunlight while maintaining comfortable lighting levels.

“Daylighting Is Too Expensive”

While there may be an initial investment in high-quality daylighting systems, the long-term energy savings and enhanced occupant well-being often outweigh the costs. Many energy-efficient daylighting solutions qualify for rebates and incentives, making them a smart investment for both commercial and residential buildings.

“Artificial Lighting Is Just as Good”

While modern artificial lighting systems are highly advanced, they cannot replicate the full spectrum and health benefits of natural light. Properly designed daylighting systems provide superior light quality while reducing energy use and improving sustainability.

How to Implement Effective Daylighting

For architects, builders, and property owners looking to maximize the benefits of daylighting, here are some key considerations:

• Utilize High-Performance Glazing – Advanced glazing materials optimize light transmittance while controlling unwanted heat gain.
• Incorporate Overhangs and Shading Devices – These elements help diffuse direct sunlight and prevent glare while maintaining visibility.
• Integrate Smart Lighting Systems – Automated lighting systems adjust artificial lighting levels based on available natural light, ensuring optimal energy savings.
• Design for Reflectance and Diffusion – Using materials with high reflectance and strategic placement of light-diffusing surfaces can help evenly distribute natural light throughout a space.

Final Thoughts

The Alder’s team believes that good daylighting is about more than just aesthetics—it’s about energy efficiency, sustainability, and enhancing the well-being of building occupants. By implementing smart daylighting design, you can create comfortable, productive, and environmentally friendly interior spaces in every building you design and/or construct.
