In contemporary architecture, curtain walls have become a defining feature, offering sleek aesthetics and expansive glass façades that maximize natural light and views. However, traditional curtain wall systems can be energy-intensive and environmentally costly. Eco curtain walls — designed with sustainable materials and energy-efficient technologies — are emerging as a vital solution for green buildings.
This blog explores how eco curtain walls integrate sustainability and modern design, the materials involved, and their role in achieving energy efficiency and environmental certifications in Canadian construction.
What Are Curtain Walls?
Curtain walls are non-structural exterior building envelopes that typically consist of glass panels supported by lightweight frames. They do not bear loads from the building but act as a protective barrier against weather while allowing natural light penetration.
Their popularity stems from architectural flexibility, modern appearance, and ability to create open, airy interiors. However, large glass surfaces can contribute to heat gain/loss, increasing energy demand for heating and cooling.
Why Choose Eco Curtain Walls?
Eco curtain walls aim to reduce the environmental impact of conventional curtain wall systems by improving energy performance, reducing material waste, and incorporating recyclable or renewable materials. They contribute to:
Lower operational energy consumption
Enhanced occupant comfort through thermal and acoustic insulation
Reduced embodied carbon through sustainable material selection
Compliance with green building certifications like LEED and Zero Carbon programs
Key Sustainable Materials for Eco Curtain Walls
Recycled Aluminum Frames:
Aluminum is common in curtain wall framing due to strength and light weight. Using recycled aluminum reduces energy consumption and emissions associated with primary aluminum production.
Low-E and Triple Glazing Glass:
Low-emissivity (Low-E) coatings minimize heat transfer while maximizing daylight. Triple glazing offers superior insulation, reducing heating and cooling loads.
Thermally Broken Frames:
Thermal breaks interrupt heat flow through metal frames, improving energy efficiency by reducing thermal bridging.
Bioplastics and Natural Fiber Composites:
Innovations include frame components made from bioplastics reinforced with natural fibers like hemp or flax, reducing fossil fuel reliance.
Solar Control Films and Dynamic Glass:
Smart glass technologies adjust tint or reflectivity based on solar exposure, optimizing energy use without sacrificing transparency.
Design Strategies for Eco Curtain Walls
Optimized Orientation: Position curtain walls to balance daylight and solar heat gain, leveraging shading devices or fins.
Integrated Ventilation: Incorporate operable sections to improve natural ventilation and indoor air quality.
Modular Prefabrication: Prefabricated eco curtain wall panels reduce onsite waste and construction time.
Recyclability: Design for disassembly at end of life to facilitate material reuse.
Role of Eco Curtain Walls in Green Building Certification
Eco curtain walls support key criteria in certifications such as LEED, WELL, and Zero Carbon Building standards by:
Enhancing energy performance through improved insulation and solar control
Using materials with verified environmental product declarations (EPDs)
Promoting occupant wellness with natural daylight and views
Supporting sustainable sourcing and waste reduction
