This document discusses eco-friendly building materials. It defines eco-friendly materials as those that cause minimum damage to the environment from raw material extraction through the final product. Key properties of eco-friendly materials are that they require minimum energy for manufacturing, are recyclable and reusable, and are locally available. Examples discussed include bamboo, mud bricks, fly ash bricks and plywood made from agricultural waste. The document also explores how to determine if a material is truly eco-friendly based on factors like availability, embodied energy, and potential environmental impacts.

- 1. UNIT-2 EMERGING BUILDING MATERIALS “ECO FRIENDLY MATERIALS”
- 2. EMERGING BUILDING MATERIALS • Bendable concrete, Self healing concrete, Translucent concrete • Electrified wood • Bio engineered bricks • Sensitiles • Carbon fibers • Liquid granite • Eco bricks
- 6. Eco-friendly materials : “The materials which cause minimum damage to the environment, since the use of raw materials to final product, are considered to be eco-friendly materials” The Properties of Eco-friendly materials are: 1.Minimum damage to the environment. 2.Require minimum energy for manufacturing. 3.It should be recyclable and reusable. 4.Locally available and can be extracted easily from nature.
- 7. WHY..?? • Phenomenal growth in the construction industry that depends upon depletable resources. • Production of building materials leads to irreversible environmental impacts. • Using eco-friendly materials is the best way to build a eco-friendly building.
- 8. PROPERTIES Renewable Source Reuse of Waste product ECO-FRIENDLY MATERIALS& TECHNIQUES Embodied Energy Local Availability Reduction in air, land and water pollution Durability & Life span Aids Energy Efficiency in buildings Biodegradable Reuse/recycle
- 9. Eco-friendly materials : Naturally available eco-friendly materials or products developed using Eco-friendly raw- materials are 1.Bamboo / timber 2.Sun dried bricks. 3.Mud used for houses, wall plastering.
- 10. Eco-friendly materials : materials can also be waste products of some The Eco-friendly manufactured using industries. theseThe following materials fall under categories. 1.Fly ash Bricks 2.Ply-wood Manufactured from Bagasse.
- 11. HOW TO FIND IF A BUILDING MATERIAL IS ECO FRIENDLY OR NOT…?? EXAMPLE:- BUILDING MATERIAL – WOOD ECO FRIENDLY?? NON ECO FRIENDLY?
- 12. Case-1 Wood - eco friendly Availability - 90% Case-2 Wood – Non eco friendly Availability - 20%
- 13. SOLAR PANEL TILES • Transform the energy of sun into usable electricity to power your home.
- 14. UNFIRED CLAY BRICKS • Using earth materials & are air dried instead of fired conventional bricks. • Eco friendly. • Benefit of reducing the energy used in manufacturing & increases strength & decreases shrinkage.
- 15. FLYASH BRICKS
- 19. REDUCES POLLUTION Air Pollution- Use of materials with low VOC emissions e.g. Cement Paints Water Pollution – Materials that prevent leaching. Land Pollution- Materials that reuse waste that would otherwise have resulted in landfill. e.g. Flyash Bricks.
