The Comparative Study

This paper presents an overview on the comparative study between the precast and conventional building construction methods for housing project in Sarawak. In this study, a residential building project with double-storey terrace houses was chosen for the comparative study as they have typical structural layout plans with minor variation. The same building was designed into both conventional and precast structural layout respectively in order to obtain direct comparison results. To ensure the results obtained are representative and unbiased, the structural components integrated in both construction methods are listed and each critical cost component, for instance the project direct and indirect costs were broken down further in order to evaluate the total building construction costs. From the research results, it can induce the relationship between the time and costs evaluation. The overall construction period for the conventional building construction method was 240 days while the precast building construction method was 82 days. As compared across the results for the project construction costs, it shows that precast construction method with RM 354,969.50 is more cost effective with about 19% less than the conventional building method with total amount of RM 422,687.85. The results reflect the significance on selection of the construction method, namely the precast building construction method not only can shorter the construction periods but also reduce the construction costs since it reduces greatly the expenses on the project direct costs particularly the machineries costs.

Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

Building materials and construction technology are strongly interrelated with the pillars for sustainable development (e.g. environment, society economy, culture and politics). Earth Building, an 11,000-year-old practice of building using sustainable and earth materials, is practiced worldwide. Earth has been used to construct walls, floors, roofs, and even furniture. Today it is estimated that between 33-50%of the world's population is housed in earth homes. This chapter reviews the two-year process of earth buildings and earth architecture carried out by the Department of Architecture Faculty of Built Environment and Engineering at National University of Malaysia (UKM). The current research emphasis is on the types, construction methods, and architectural aspects of earth buildings and earth architecture. The current manuscript compares type of earth buildings and their properties and applications based on building materials and architectural aspects in construction.

Sustainable Environment

The extraction of building materials from their resources through harvesting, preservation, and utilization has become a significant segment of human contribution to the global ecosystem since the industrial revolution. Bamboo is the world's fastest-growing woody plant, and bamboo grows multiple times quicker than most species. Housing is one of the focused demands for bamboo, and as a result of the current scarcity of home units, the demand for bamboo is increasing. Bamboo building construction is portrayed by a basic edge approach like that applied in traditional building design and construction. Applying bamboo as an environmentally friendly material is seen as a movement towards creating a sustainable environment and reducing greenhouse emissions. The need to employ government policy in addressing the production and application of bamboo is reported, and the challenges of bamboo in the global market are highlighted in this chapter.

Weather Changes

Research from the International Energy Agency about indoor ambiences and nearly zero energy buildings (nZEB) in the past has been centred on different aspects such as the prediction of indoor conditions as a function of the weather using laboratory material properties for simulations and real sampled data for validation. Thus, it is possible to use real data for defining behavioural groups of indoor ambiences as a function of real vapour permeability of internal coverings. However, this method is not suitable for modelling it and predicting its behaviour under weather changes, which is of interest to improve the method of selection and use of building construction materials. In this research, artificial intelligence procedures were employed as the first model of permeable coverings material behaviour to provide a newer understanding of building materials and applications for the generation of new control procedures between the mechanical and electronic point of view of building construction materials.
