Green Mark Certified Interior Materials Guide – Goodrich
Green Mark certified materials are increasingly essential for construction and renovation projects in Singapore. As the Building and Construction Authority (BCA) raises sustainability standards across the built environment, architects, interior designers, and developers need to understand how material choices contribute to Green Mark certification.
This guide explains how interior furnishing materials — flooring, wallcoverings, and fabrics — can support Green Mark requirements and help projects achieve higher certification levels.
What is the BCA Green Mark Scheme?
The BCA Green Mark scheme is Singapore’s green building rating system, established in 2005. It evaluates buildings across categories including energy efficiency, water efficiency, environmental protection, indoor environmental quality, and other green features.
Since 2008, new buildings and major retrofits in Singapore have been required to meet minimum Green Mark standards. The scheme has undergone several revisions, with the latest version — Green Mark 2021 — placing greater emphasis on embodied carbon, health and wellbeing, and whole-life sustainability.
Green Mark certification levels are:
- Green Mark Certified: Meets minimum sustainability requirements.
- Green Mark GoldPLUS: Demonstrates strong commitment to sustainability.
- Green Mark Platinum: Achieves exceptional sustainability performance.
- Green Mark Super Low Energy / Zero Energy: The highest tiers, focused on energy performance.
Interior materials contribute primarily to the Indoor Environmental Quality (IEQ) and Sustainability sections of the Green Mark assessment, though they also influence embodied carbon calculations.
How Interior Materials Earn Green Mark Credits
Several aspects of interior material specification are assessed under Green Mark. Understanding these categories helps project teams make informed choices.
Low VOC Emissions
Volatile organic compounds (VOCs) released by interior materials affect indoor air quality. Green Mark awards credits for specifying materials with low or zero VOC emissions. This applies to flooring, wallcoverings, adhesives, and coatings.
Look for products certified under recognised standards such as FloorScore, GREENGUARD, or the Singapore Green Building Product (SGBP) certification scheme. These third-party certifications verify that materials meet stringent emission limits for formaldehyde, total VOCs, and other pollutants.
Recycled and Sustainable Content
Materials incorporating recycled content earn credits under Green Mark’s resource efficiency category. Carpet tiles made with recycled nylon fibre, vinyl flooring with recycled PVC content, and wallcoverings using sustainably sourced substrates all contribute.
The percentage of recycled content matters. Higher proportions typically earn more credits, and post-consumer recycled content is valued more highly than pre-consumer (manufacturing) waste.
Sustainable Sourcing
Materials sourced from responsibly managed supply chains contribute to Green Mark compliance. This includes FSC-certified wood products, sustainably harvested natural fibres, and products manufactured under environmental management systems (ISO 14001).
Durability and Lifecycle
Green Mark 2021 places increasing weight on whole-life sustainability. Materials that last longer, require less maintenance, and can be recycled at end of life receive favourable assessment. High-quality luxury vinyl flooring with extended warranties and recyclability programmes aligns with this requirement.
Green Mark-Friendly Flooring Options
Flooring is typically the largest interior surface area and has the most significant impact on both indoor air quality and resource consumption.
| Flooring Type | Green Mark Benefits | Certifications to Look For |
|---|---|---|
| LVT / SPC with recycled content | Low VOC, recycled materials, durability | FloorScore, SGBP, GREENGUARD |
| Carpet tiles with recycled backing | Recycled nylon and backing, acoustic benefits | Cradle to Cradle, NSF/ANSI 140 |
| Homogeneous vinyl (phthalate-free) | Low VOC, long lifecycle, recyclable | FloorScore, GREENGUARD Gold |
| Natural linoleum | Bio-based content, biodegradable, low VOC | Blue Angel, FloorScore |
When specifying flooring for Green Mark projects, request Environmental Product Declarations (EPDs) from manufacturers. EPDs provide independently verified data on a product’s environmental impact across its lifecycle, which Green Mark assessors can use directly in their evaluation.
Wallcoverings and Green Mark Compliance
Wallcoverings contribute to Green Mark primarily through indoor air quality performance. Low-VOC wallpapers and wallcoverings — particularly those free of PVC, heavy metals, and plasticisers — support the IEQ requirements.
Japanese wallcovering manufacturers, including those in Goodrich Global’s portfolio, have a strong track record in sustainable production. Many products are manufactured under strict environmental management systems and carry certifications for low emissions and sustainable raw materials.
Non-woven wallpapers using natural or recycled fibres offer additional sustainability benefits. They are easier to remove at end of life than vinyl-coated wallpapers, reducing renovation waste — a consideration that Green Mark 2021’s lifecycle approach rewards.
Fabrics and Sustainable Specification
Upholstery and drapery fabrics contribute to Green Mark through material composition, manufacturing processes, and end-of-life recyclability.
Fabrics made from recycled polyester (rPET), organic cotton, or sustainably sourced natural fibres align with Green Mark’s sustainable materials requirements. Performance fabrics that maintain their properties over many years reduce replacement frequency, contributing to lifecycle sustainability.
For projects targeting higher Green Mark tiers, specify fabrics with OEKO-TEX Standard 100 certification (free from harmful substances) or Global Recycled Standard (GRS) certification for recycled content verification.
Final Thoughts
Green Mark certified materials are no longer a niche concern — they are a mainstream requirement for Singapore’s construction and renovation industry. By selecting interior materials with verified environmental credentials, project teams can earn Green Mark credits while creating healthier indoor environments.
Working with suppliers who understand Green Mark requirements and can provide the necessary certifications and documentation streamlines the specification process and reduces the risk of compliance gaps during assessment.
