Selecting the right type of glass in educational buildings plays a crucial role in temperature regulation and energy efficiency. In newly constructed classrooms, balancing natural light and airy spaces with managing solar overheating can be essential to ensure a comfortable learning environment. Multiple research papers have shown that overheating classrooms can negatively impact student performance and lead to increased energy consumption. Low E glass solutions, such as those offered by Metro Glass, particularly their SunX product range, present a viable approach to addressing this challenge.

The right glass selection can mitigate the effects of solar heat gain while allowing outdoor views and natural light, creating a more comfortable learning environment for students and teachers, while not requiring extra ongoing operational costs. Studies indicate that poorly regulated temperatures can disrupt learning and lead to higher absenteeism. For instance, the research published by the Journal of Building Physics highlights the significance of façade design and glazing selection in controlling solar heat gain and ensuring thermal comfort in buildings, including educational spaces. Additionally, another study from Energy and Buildings emphasises that advanced glazing solutions with reflective and low-emissivity coatings can reduce the amount of solar radiation entering classrooms, which in turn lowers the need for cooling systems and saves energy.

Metro Glass's SunX Grey is designed to combat exactly this issue. It incorporates a specialised coating that reflects a significant portion of solar radiation while allowing sufficient natural light to enter. This ensures that classrooms remain well-lit without overheating. The product is engineered for high performance, making it an ideal economical choice for new classrooms where balancing natural light and temperature control is critical.

A recent example of this approach can be seen in the refurbishment of the school hall at New Plymouth Girls' High School, Hōro Kura. 

In this project, Metro’s glass expertise played a key role when working with Brian Lee of Boon Architects in transforming the hall into a space that is not only visually appealing but also energy efficient. The installation of advanced glazing solutions contributed to a more stable indoor environment, reducing the reliance on artificial cooling, and solving the long-standing problem of overheating in the foyer area. The success of this project underscores the importance of thoughtful glass selection in educational settings, where creating a conducive environment for learning is paramount.

The latest product in the range, SunX Reflect offers the addition of privacy to the high performance, and again supplies a consistent colour hue regardless of the thickness of glass.

Selecting high-performance glazing solutions like SunX Grey or SunX Reflect is a cost-effective solution to temperature control problems in modern classroom design. By incorporating such technologies, schools can maintain comfortable indoor environments, reduce energy consumption, and promote better learning outcomes. As demonstrated by recent projects like New Plymouth Girls’ High School, choosing the right glass can have a lasting impact on both energy efficiency and student well-being.
