The Environmental Impact of Skylights: An Overview 1

For decades, skylights have been incorporated into building designs to add natural light to interior spaces. Skylights are preferred in modern designs that emphasize environmental sustainability and energy efficiency. However, there are various environmental impacts associated with the installation and operation of skylights. This article aims to provide an overview of the positive and negative environmental effects associated with skylights and the appropriate measures that building owners can take to minimize their ecological footprint.

Benefits of Skylights on the Environment

Skylights can provide abundant sunlight to interior spaces, reducing the need for artificial lighting. By reducing the dependence on artificial lighting, building owners can save on energy costs, minimize greenhouse gas emissions, and mitigate environmental impacts resulting from energy production. Additionally, the utilization of natural light can enhance indoor air quality, reduce the need for air conditioning, and regulate indoor temperature.

Environmental Concerns with Skylights

While skylights offer many environmental benefits, there are also several environmental concerns to consider. Skylights can increase heat gain in the interior spaces, leading to increased cooling costs during the warmer months. The heat gain can also result in reduced roof insulation effectiveness, contributing to energy loss and greenhouse gas emissions. The tint or glaze on the skylight that reduces heat transmission may affect the natural light that passes through it, leading to discomfort and low productivity of occupants. Additionally, skylights can cause reflections and glare, potentially distracting drivers or compromising a building’s privacy, if installed improperly.

Minimizing the Environmental Impact of Skylights

To minimize the environmental impact of skylights, it is crucial to take certain measures during their installation and operation. One way is to install light shelves that effectively reflect direct sunlight and increase the natural light that reaches the deeper parts of the interior spaces. They reduce heat gain and protect occupants from glare that could result in discomfort and affect their productivity levels. Proper placement and insulation of skylights can reduce energy loss and heat gain. Building owners can also opt for skylights that are Energy Star certified to minimize energy loss and greenhouse gas emissions and meet energy efficiency standards. Lastly, building owners must conduct adequate research and seek professional guidance to ensure they install skylights that meet appropriate standards and regulations.


Skylights have enormous potential to provide abundant natural light, reduce energy consumption, and improve indoor air quality. The environmental impact of skylights remains a critical issue, however, with the associated risks such as heat gain and glare. Building owners, architects, and environmental experts need to keep working together to address the environmental concerns related to skylights. By taking appropriate measures such as installing light shelves, proper insulation, and using Energy Star certified skylights, we can harness the benefits of skylights while minimizing environmental impacts and building sustainable structures that benefit society and the environment for generations to come.
