Kingspan Insulation has recently published Environmental Product Declarations (EPDs) for several of its insulation products in the Australasian market. These include the Kooltherm K3 Floorboard, Kooltherm K8 Cavity Board, Kooltherm K12 Framing Board, and the KoolDuct System. With this latest release, all Kooltherm products now have an EPD. The publication of these EPDs reflect Kingspan's commitment to transparency and environmental sustainability by providing detailed, quantified environmental data. These EPDs empower architects, engineers, and builders make informed decisions about the materials they use in construction projects. By offering these resources, Kingspan aim to help reduce the embodied carbon of buildings, supporting industry sustainability goals and building certification schemes across Australia.
What is an EPD?
An EPD is a comprehensive report that transparently outlines the environmental impacts of a product throughout its entire lifecycle from cradle-to-grave. As an internationally recognised and standardised disclosure, an EPD provides quantified environmental data using predetermined parameters, along with additional relevant environmental information when applicable. Independently verified, EPDs enable stakeholders to assess the sustainability credentials of the product, compare it with alternatives, and make decisions based on transparent, credible data.
How can the Kingspan Insulation EPDs be used in Australia?
1. Green Star Certification and Sustainable Building Practices
One of the primary uses of Kingspan’s newly published EPDs is their potential contribution to Green Star certification under the Green Building Council of Australia (GBCA) rating system. By specifying products with EPDs and other sustainability certifications, building projects can earn points under the Responsible Products Program. This credit rewards the use of sustainable materials that meet stringent environmental performance standards.
2. Ensure Material Selection Aligns with Carbon Reduction Goals
With Australia's growing commitment to reducing embodied carbon in construction, EPDs provide builders, engineers, and contractors with the data needed to assess and minimise the carbon footprint of their materials. By offering verified information on a product's environmental impact, including embodied carbon, EPDs empower teams to make decisions that support net-zero carbon targets. In large-scale projects where embodied carbon reduction is critical, the use of products with EPDs ensures that material selections align with carbon reduction goals and regulatory requirements.
3. Compliance with Local Regulations and Sustainability Standards
EPDs are also essential for meeting the requirements of various Australian building codes and sustainability standards. For example, in New South Wales (NSW), the BASIX (Building Sustainability Index) is a key regulation that aims to improve the sustainability and energy efficiency of residential buildings. While BASIX does not directly mandate the use of EPDs, these declarations can play a crucial role in helping building projects meet some of BASIX’s sustainability requirements.
4. Life Cycle Assessment (LCA) and Design Tools
Architects and designers use EPDs to conduct Life Cycle Assessments (LCAs) during the design phase of a project. Tools like One Click LCA incorporate EPDs to compare the environmental impacts of various building materials. Kingspan’s EPDs for its insulation products provide essential data on embodied carbon, energy use, and other environmental impacts of materials, enabling architects to assess and make informed decisions early in the design process.
5. Contribution to Building Certification Programs (NABERS)
EPDs can play a vital role in earning credits under the National Australian Built Environment Rating System (NABERS). NABERS assesses a building's operational and environmental performance, and using products with EPDs can help projects earn points in areas like waste management, energy efficiency, and sustainable material selection. By integrating Kingspan’s insulation products with EPDs, buildings can showcase their commitment to sustainable practices, achieve a higher NABERS rating and enhance their overall environmental performance.
6. Supporting Circular Economy and Waste Reduction
The construction industry is placing greater emphasis on circular economy principles and waste minimisation. EPDs offer valuable insights into the recyclability and end-of-life disposal of products, helping to reduce waste generated during the construction and demolition phases. Kingspan’s EPDs provide detailed information on the repurposing potential of its products, supporting projects that aim to minimise their environmental impact.
