Here’s a comprehensive overview of the most promising and widely used sustainable building materials in 2025, grouped by category with key advantages, applications, and real-world performance notes. 1. High-Performance Natural & Bio-Based Materials  Cross-Laminated Timber (CLT) & Mass Timber – Sequester carbon (1 m³ of wood stores ~1 ton of CO₂) – Now used in buildings up to 25–30 stories (e.g., Ascent in Milwaukee, 86.6 m, 2022; new projects pushing 40+ stories) – Fire-rated systems + acoustic improvements make it viable for mid/high-rise. Hempcrete (hemp-lime composite) – Carbon-negative (hemp absorbs CO₂ rapidly, lime reabsorbs CO₂ while curing) – Excellent thermal mass + breathability → reduces heating/cooling loads 30–50 % – Mostly used for infill walls and insulation in Europe & North America. Mycelium (mushroom) composites – Grown in days, fully compostable – Used for insulation panels, acoustic tiles, and even load-bearing bricks (strength now reaching 2–5 MPa)....

Green Building  Green Building does not refer to building which are green in colour or have been constructed with green parks around. It refers to a conscious practice of addressing the issue of resource conservation in an integrated and scientific manner. By definition, a green building is one which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building. Modern-day building have a tendency to use designs and materials which are resource-intensive and are quite often operate in isolation with the nature. Such buildings are very poor in energy efficiency and generate a lot of waste, adding to faster depletion of natural resources. Thus, building are seen today as one of the major pollutants to affect urban air quality and contribute to climate change. GREEN BUILDING A green building depletes very little of the natural resources during its constructi...
