Initially, timber was considered only as an easily accessible and processable material in nature; however, its excellent properties have since become better understood. During the discovery of new building materials and thanks to new technological development processes, industrial processing technologies and gradually drastically decreasing forest areas, wood has become an increasingly neglected material. Load-bearing structures are made mostly of reinforced concrete or steel elements. However, ecological changes, the obvious problems associated with environmental pollution and climate change, are drawing increasing attention to the importance of environmental awareness. These factors are attracting increased attention to wood as a building material. The increased demand for timber as a building material offers the possibility of improving its mechanical and physical properties, and so new wood-based composite materials or new joints of timber structures are being developed to ensure a better load capacity and stiffness of the structure. Therefore, this article deals with the improvement of the frame connection of the timber frame column and a diaphragm beam using mechanical fasteners. In common practice, bolts or a combination of bolts and pins are used for this type of connection. The subject of the research and its motivation was to replace these commonly used fasteners with more modern ones to shorten and simplify the assembly time and to improve the load capacity and rigidity of this type of frame connection.

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

The climatic conditions in a man-made urban environment may differ appreciably from those in the surrounding natural or rural environs.... each urban man-made buildings, roads, parking area, factories......creates around and above it a modified climate with which it interacts [1].Outdoor thermal comfort has gained importance in thermal comfort studies especially in tropical countries. In country like India, culturally the activities are spread both indoors and outdoors. Therefore the need for ambient outdoor environment gains importance. As there are many factors that contribute to outdoor thermal comfort (climatic factors and physical factors), this study aims in analyzing the impact of building material contribution, in an institutional courtyard. In order to understand the thermal contribution of various building materials and to suggest material choice to designers, ENVIMET is used for simulation purpose. The outdoor thermal comfort index employed in this study is PET (Physiological Equivalent Temperature), calibrated using RAYMAN.

Design And Construction

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

Building adaptation projects may involve hazardous and toxic substances hidden in the building materials. These substances pose dangers to health and safety, disturbing the environment and affecting the projects’ turnover. Literature reviews on building adaptation and building materials information management found that vital information are seldom available. This study determines the awareness and knowledge of stakeholders in Malaysian building adaptation projects on the required building materials information. Analysis of interviews with 16 experienced stakeholders revealed the lack of awareness and information on existing building materials that may contain hazardous and toxic substances. Thus, building material information is critically required for future sustainability.Keywords: Awareness and knowledge on building material; Building adaptation; Building material information; Hazardous and toxic building materialeISSN 2398-4295 © 2018.

Timber has been rediscovered as the building material of choice in recent years, especially in industrialised countries, with the shift of focus on attitudes towards sustainability that include use of natural resources and reduction of CO 2 emissions in manufacturing building materials. The environmental qualities of wood (energy-efficiency, healphy building material, ability to be recycled) are matched by few materials used in constructions nowadays, makeing it suitable for a wide range of applications. The combustibility of wood is limiting its use in construction, an important weakness in terms of sustainability, as health and cost issues constitute essential conditions in sustainability assessment methods. Arguably, fire safety constitutes the foremost precondition in choosing wood as the building material. In the case of fire, wood burns on the surface, releases energy and contributes to the fire propagation and spread of smoke. In order to insure greater safety for timber constructions, both passive and active measures of fire protection can be implemented, with the main objectives of improving the security of occupants, limitations of financial loss, protection of the environment in the case of fire. Despite the fear of using wood, the material has a better behavior in terms of fire than assumed, and even with structures more susceptible at fire risks, such as platform framing, measures can be taken in order to improve safety, as further explained in the article. The article analyses the concept of sustainability and the extent to which timber constructions observe these criteria, focusing on the means of increasing safety by fire protection methods with respect to the environment.
