Traditional construction processes are blamed to be un-sustainable in terms of resource depletion due to the application of un-sustainable products and construction processes.
The decrease in on-site production will result in an absolute decrease in waste production and the decrease in waste generation.
As for Industrialize Building System (IBS), site deliveries were monitored over the construction period.
The solid waste such as spoiled materials from off-cuts and packaging can be stored for the purpose of selective process to identify the material suitable for recycling and reuse.
A proper storage system can lead to efficiency gains by grouping the reusable solid waste and removing the spoiled solid waste.
However, the most important issues of sustainability and Green are how to establish the renewable energy for the consumption of artificial ventilation for the buildings.
Energy saving materials to be applied by designers by application of thermal insulation to the building envelope was suggested such as roof insulation, wall insulation, insulated glass, and floor insulation.
Energy considerations are looking at the various aspects of design as follows; the orientation and natural ventilation of the building, solar protection, and passive solar design.
Sustainability measures are usually considered in the early phases of new construction projects whilst sustainable maintenance and demolition is often still neglected.
Therefore various innovative industrially produced standardized building systems based on the life-cycle of the buildings which IBS could play in driving up quality, value and increasing the lifespan of the building and their components.
There are three-pronged strategies to innovate the IBS to achieve sustainability and Green construction as follows; Industrial – to cut materials, costs & time and increase quality, e.g. modular dimensioning and engineering details, prototype testing, and clear assembly instructions; Flexibility – innovations for vertical and horizontal piping, providing various possible locations for toilets, kitchens and bathrooms; Demountability – separate replacement of components with various life spans by the adjustability/adaptability of all parts in differing degrees such as structure (limited), installation (practically unlimited), outer shell (limited and modular), interior finishing (practically unlimited and modular).
This is mainly accomplished by designing in standardized materials and the use of exact sizes of prefabricated components as follows; standardized building materials; prefabricated elements; recycled and renewable materials; design for flexibility and dismantling.
The government acknowledges that while the IBS offers positive impacts to the industry, there are still barriers to the total achievement of the IBS Roadmap targets.
Therefore, and in-line with the IBS Roadmap and Construction Industry Master Plan (CIMP) 2006-2015, CIDB Malaysia has taken an initiative to form the IBS Centre.
This approach need to be identified to enable such development, planning and construction processes that incorporate design and construction of building that include the life cycle oriented performance and cost guarantees.
