  • Water resources indicators: Save water.
  • Sewage and garbage reduction indicators: Reduce the daily use of sewage and garbage.

What are the Classifications of Green Building Materials?

  1. Ecological (environmentally friendly) building materials: In the whole life cycle of building materials from the production system, in addition to meeting the basic performance requirements, it is the most natural building material for the global environment, consuming the least energy and processing the least resources.
    • Natural building materials without the crisis of scarcity: Such as rattan, bamboo, grass, wool, clay, and other natural woods that are inexhaustible, or wood for sustainable forestry management. Most of the wood for sustainable forestry management comes from cold temperate forests in northern Europe and the United States, and the certificate of origin of the sustainable forest can be used as the basis for the identification of green building materials. Most of the wood commonly used in Taiwan comes from unsustainable tropical forests. This move not only swallows the tropical rainforest but also accelerates the extinction of tropical creatures. It is not a green building material to encourage the use of.
    • Ecological pest control and preservative: General plant extracts have the problems of high volatility and short persistence, but insect repellants and preservatives made from natural plants can overcome this problem, and the toxicity test and safety of their oil preparations are acceptable to the public authority’s thing.
    • Natural ecological building materials: Natural ecological building materials can replace non-decorative surface building materials such as toxic chemically synthesized caulks, wood surface coatings, and thermal insulation materials. It is not only environmentally friendly but also maintains the quality of healthy life at home. For example, the use of non-foamed caulks and natural thermal insulation materials can reduce the damage of chlorofluorocarbons to the ozone layer, which is of great help to global environmental protection.
  2. Healthy building materials: Building materials with low emission, low pollution, low odor, and low physiological hazard characteristics, mainly aiming at low emission of formaldehyde and low volatile organic compounds, such as low VOC plywood, low chemical gas emission Sexual building materials, water-based environmentally friendly paints, natural ecological paints, and other building materials.
    • Ecological coating: Ecological coatings such as water-based environmentally friendly paints, natural ecological paints, and other building materials. If you can try to reduce the pollution of paint, it is most beneficial to the indoor environment. Healthy and natural paint emphasize the use of harmless and non-toxic pigments, such as persimmon, linseed oil, resin, and other plant ingredients, plant pigments, honey, beeswax, essential oils, soybeans, etc. After painting, it can protect the strengthening, moisturizing, and breathing of wood. Prevent static electricity, good waterproof, is antibacterial, has strong weather resistance, simple construction, and can be used for indoor and outdoor, furniture.
    • Ecological adhesive: The environmentally friendly adhesive has the function of humidity control, prevents indoor condensation, good hydrophilicity, anti-pollution, and static electricity prevention, inhibits pathogenic bacteria, decomposes odor, promotes air circulation, and saves energy. It can be used for inner and outer walls, patios, roofs, etc., to prevent surface acid rain and air pollution.
  3. High-performance building materials: Refers to building materials with high performance, which can overcome the performance defects of traditional building materials to improve quality and efficiency. Common problems in life such as noise control and poor water retention capacity of the base can be improved to a considerable extent by using building materials with better performance.
    • High-performance soundproof green building materials: Building materials that can effectively prevent noise from affecting the quality of life.
    • High-performance permeable green building materials: Products with good water permeability to surface runoff, which meet the requirements of base water retention indicators.
  4. Renewable building materials: Refers to building materials with low processing degree, low energy consumption, low CO2 emission, low pollution emission, easy to decompose naturally, reusable, conforming to the local industrial ecology, and no scarcity crisis.
    • Regeneration and recycling of building materials: Refers to recyclable building materials such as old wood, old tires, old furniture, old equipment, recycling, and reuse, and can be further subdivided into the following categories:
      • Recycled wood building materials: The interior decoration of buildings, floors, ceilings, skirting boards, partition boards, doors, and various wooden furniture, etc.
      • Stone recycled building materials: Stone building materials are produced by using waste concrete materials or inorganic stone materials that are harmless in the process.
      • Mixed material recycled building materials: Wood or stone building materials are mixed with various industrial non-hazardous wastes such as waste glass, etc., to promote the function of building materials. Such as imitation wood, lightweight aggregates, permeable bricks, etc.
    • Local building materials: The production of building materials is an industrial product with high energy consumption density. From the perspective of the life cycle of building materials, their production, transportation, secondary processing, and even disposal consume a lot of energy. CO2, so the use of building materials not only consumes energy and electricity but also increases the load on the global environment. Therefore, building materials with fewer processing times are better for environmental protection, low energy consumption, high recyclability, repeatable assembly, and good durability, to reduce the overall environmental load.

What is the Green Building Appeal?
