Global construction market is talking about going green today, demand of green building material is arising now. This is also due to the incentives provided by construction council, government, income tax authority to reward developer to build more green building. Hence, eco-friendly building materials are getting more popularity, therefore increase the number of eco-friendly building materials supplier in Malaysia. At the same time, eco-friendly materials supplier in Malaysia also come out with many innovations in many applications for building.
First thing normally eco-friendly building material has to meet is that, it increases overall energy efficiency of the building, putting aside the effect of purely architectural design. Energy efficiency building has wide coverage, including roof, wall, slab to other interior products. For example, roof insulation materials against sunlight, lightweight slab to reduce the structural materials usage and cost.
In addition, when green building material authority certifying these materials as eco-friendly and allocate higher rating point, few points will be evaluated such as the raw material’s renewability, production’s pollution level. For example, some raw materials may not be renewable and the regrowth is not possible like tree’s timber. In some circumstances, the growth of such raw materials might also leads to adverse impact on the environment. Furthermore, green building materials certifier also does not allow the production process and method of such building materials that might cause pollution or involves complicated high energy consumption.
A very good example of materials that are not green but necessary is stone quarrying, without a proper planning, hill can be eroded and risking the biodiversity of the river (if linked to) or damaging the building nearby. However, one of the most common eco-friendly building materials in Malaysia is bamboo without any doubt. Bamboo’s growth is fast, easy to harvest and further processed into building material, minimal damage can be brought by its planting, reaping, production and even its waste is biodegradable and reusable.
Let us get into details on more criteria of eco-friendly material source, for example, the usability of waste from its harvesting, production or throughout the lifespan of the material. For example, most of the agricultural-based materials such as wooden door, bagasse board. At the same time, construction industry players who already long enough in the field do also know that paints are not healthy originally; but due to the emerging needs of healthier and greener building materials, paints nowadays are mostly having low VOC (Volatile Organic Compound) emission to the air that reduce the air pollution.
The lower the embodied energy of a produced building material, the higher its rating in term of eco-friendly. For example, timber has the lowest while aluminium, steel have the most because it requires a lot of power and energy to produce, shape, cut and transformed into usable finished product. The energy meant utilization of electricity, man power, time hour which all these are waste of resources. The higher the consumption of resources to convert multiple or a single raw material into ready-to-use building material, the higher the embodied energy, it includes transporting the ready product to the construction site. There are also few other low embodied energy eco-friendly building materials in Malaysia certified by experts such as concrete, fibreglass insulation material, plaster ceiling (gypsum board), bricks or timber building materials.
Moreover, eco-friendly building materials supplier in Malaysia will also be evaluated from the perspective of water pollution and land pollution. Green building materials should not causing any further pollution to the river, sea, drain and landfill waste. Likewise, the reusable and recyclable of building materials do also make them valuable when it comes to the time architect choose the green building materials supplier in Malaysia. Steel, aluminium, timber remain to those should have high recommendation among the similar range, of course, we have to also evaluate its biodegradable standard, such as earthen or timber materials.
Besides, the performance of the individual eco-friendly building materials should also as good as in it can achieve best result even when it stands alone without the auxiliary (other building materials). For instance, the lightweight block (Autoclaved Aerated Concrete block, AAC brick) can achieve thermal and sound insulation with lightweight feature that helps in reduction of structural cost. At the meantime, it also helps to reduce the dependency of other materials and reduction of building’s dead load alongside with energy efficiency feature; another good example is the Ferrocement.
Eco-friendly building materials supplier Malaysia also tell us that the lifespan and durability of being certified as green building materials are important. Indirectly, it also meant that low maintenance is required, long-lasting that subsequently converted into huge cost saving. Lower quantity is required to produce to replace the material if the durability is long enough, as well as reducing the amount of materials to achieve the same performance. PVC or HDPE based building materials are good examples in the form of tank, pipe, infrastructure and drainage system.
