Environmentally friendly buildings have become increasingly important to property owners and developers as they strive to reach greener standards. However, it is equally important that they do so cost-effectively without compromising durability. One widely recognized benchmark for sustainability is LEED certification.
While the certification touches on everything from energy usage to waste management, selecting sustainable materials is an important part of achieving a LEED-certified building. In an effort to reach this certification, many property owners have begun installing vinyl siding on the exteriors of their homes and businesses.
In this blog, we’ll discuss the basics of LEED certification, how vinyl siding fits into green building practices, and how it can contribute to a LEED-certified project.
What is LEED Certification?
LEED certification, developed by the U.S. Green Building Council (USGBC), focuses on a building project’s environmental and health impacts. This program assesses buildings based on several categories, including:
- Energy & Atmosphere: Minimizing energy consumption and optimizing energy efficiency.
- Materials & Resources: Using sustainable materials and reducing waste.
- Indoor Environmental Quality: Enhancing indoor air quality and comfort.
- Sustainable Sites: Encouraging the responsible use of land and reducing environmental impact.
- Water Efficiency: Promoting water conservation and management.
By meeting these and other criteria, projects can earn LEED points and achieve certification levels ranging from Certified to Platinum. The ultimate goal of LEED certification is to encourage more sustainable building practices and reduce environmental impacts, which translates into financial and environmental benefits over time.
Vinyl Siding and Sustainable Building
For decades, vinyl siding has been a popular exterior siding choice in residential and commercial buildings. It is lightweight, cost-effective, available in various colors and textures, and highly resistant to environmental damage like moisture and insects. Vinyl siding is also remarkably low-maintenance, often only requiring occasional washing to stay in good condition.
However, the environmental impact of vinyl siding has sometimes been debated due to its primary material, polyvinyl chloride (PVC), a type of plastic derived from petroleum.
Despite this, advances in vinyl siding production and recycling initiatives have made vinyl a more eco-friendly option.
Today’s vinyl siding manufacturers are committed to reducing emissions, incorporating recycled content, and developing energy-efficient siding options. With this progress, vinyl siding has the potential to contribute positively to LEED certification.
Vinyl Siding and LEED Points
While it once wouldn’t have positively impacted a project’s goal of achieving LEED certification, newer vinyl siding is a great way to move towards a greener property. Here’s how:
Materials and Resources
The LEED Materials and Resources category focuses on using sustainable and recyclable materials. Some vinyl siding products include some recycled content, which can contribute to LEED points. Furthermore, vinyl siding’s durability reduces the need for frequent replacements, ultimately decreasing waste and resource consumption over the building’s lifespan. Several vinyl siding manufacturers are part of recycling programs that collect scrap or leftover materials, helping to minimize landfill waste.
Energy and Atmosphere
Energy efficiency is one of LEED’s core focus areas, and insulated vinyl siding can help reduce a building’s energy needs. Insulated vinyl siding provides an added layer of insulation that helps maintain indoor temperatures, potentially reducing heating and cooling energy consumption. By lessening the reliance on HVAC systems, insulated vinyl siding may help lower the building’s overall energy demands, contributing to LEED points in the Energy and Atmosphere category.
Innovation in Design
If a particular type of vinyl siding provides unique environmental benefits, it could earn additional points under LEED’s Innovation in Design category. For example, some manufacturers also use life-cycle analysis (LCA) to showcase the sustainability of their products over time, which may support LEED credit through Innovation in Design.
Indoor Environmental Quality
Unlike some exterior cladding materials, vinyl siding typically doesn’t release volatile organic compounds (VOCs) indoors. VOCs can compromise indoor air quality and contribute to health issues, so choosing materials with minimal or no VOC emissions is essential for achieving LEED certification. By selecting low-emission materials like vinyl siding, builders can earn points in the Indoor Environmental Quality category.
Regional Priority Credits
LEED also offers Regional Priority Credits, which address the unique environmental concerns of different geographic areas. Vinyl siding’s durability and resistance to weathering can make it particularly suitable in regions with harsh weather conditions, from intense sunlight to heavy rain or snow. In areas where materials that withstand local environmental stresses are prioritized, vinyl siding may contribute to additional LEED points.
The Environmental Benefits of Vinyl Siding
While vinyl siding alone may not make a project LEED-certified, it can complement broader green building efforts in several ways:
- Durability and Longevity: With a 20- to 40-year lifespan, vinyl siding can significantly reduce the resources needed for repairs or replacements compared to other materials. The longevity factor minimizes waste generation and resource usage, which aligns with LEED’s sustainability goals.
- Low Maintenance: Vinyl siding doesn’t require repainting, staining, or regular repairs, so it minimizes the need for chemical treatments and products that may otherwise harm the environment.
- Potential for Recycling: Vinyl siding recycling programs are expanding, with manufacturers recovering and reusing waste materials more than ever. This helps reduce the material’s impact on landfills and enhances its eco-friendly profile.
