Building Surfaces

It must be appreciated that no building surface is perfectly flat and that the best that can be expected is the appearance of flatness. Unfortunately, this appearance can easily be destroyed by the effect of glancing light, whether natural or artificial. Illumination and Decoration of Flat Surfaces shows the effect of different light sources on a variety of lining materials and paints so that best results can be achieved. Different types of building surfaces are investigated, including set plaster, fibrous plaster, hardboard and gypsum board with gloss and semi-gloss paint applied. This full-colour edition also discusses new building materials such as cement sheet, polystyrene and various composite panels, as well as new building practices, low embodied energy materials and higher energy efficiency of buildings. Illumination and Decoration of Flat Surfaces is a must-have for people involved in the building industry, both commercial and residential.

Sustainable Building Materials

Construction industry is one of the largest consumers of the natural resources and responsible for substantial amount of CO2emission in the world. The purpose of this paper is to carry out comprehensive literature review on the low embodied energy materials and techniques used in the existing and / or new buildings in India. The paper also compares the conventional building materials and techniques, with alternative ones to assess their superiority. An investigation into the energy consumed by the building materials and techniques is computed to find out the embodied energy requirements to prove superiority of innovative construction techniques over traditional materials.

Housing is one of the biggest contributors in polluting the ozone layer and consuming the natural resources in making one. Home interior takes part in the over-produced material used for covering the interior elements, such as floor, wall, ceiling, and furniture. The article conducting is to study the green aspect of building materials to find alternative material to beautify the house that is not harming the earth. The result is options of eco material to be used in the making of greener home interior. It is materials that can be renewed, recycled, and low in embodied energy. Materials used in home interior have impact to the natures. Thus, awareness in choosing the right material to decorate the house is very important.

The introduction of life cycle assessment (LCA) to the building industry is important due to its ability to systematically quantify every environmental impact involved in every process from cradle to grave. Within the last two decades, research on LCA has increased considerably covering from manufacturing of building materials and construction processes. However, the LCA application for buildings in Asia are limited and fragmented due to different research objectives, type of buildings and locations. This paper has attempted to collect and review the application of LCA in the building industry in Asia from the selected publications over the last 12 years, from 2001 to 2012. The result shows that most LCA research basic methodology is based on International Organization of Standardization (ISO) 14040 series but with variance. It is found that the operational phase consume highest energy and concrete responsible for the highest total embodied energy and environmental impact. It also suggested that building material with low initial embodied energy does not necessarily have low life cycle energy. Overall, findings from LCA studies can help to make informed decisions in terms of environmental impact and help realizing sustainable buildings in the future.

The United States Environmental Protection Agency (EPA) has labeled as “friable” those building materials that are likely to readily release fibers. Friable materials when dry, can easily be crumbled, pulverized, or reduced to powder using hand pressure. Other asbestos containing building materials (ACBM) where the asbestos fibers are in a matrix of cement or bituminous or resinous binders are considered non-friable. However, when subjected to sanding, grinding, cutting or other forms of abrasion, these non-friable materials are to be treated as friable asbestos material. There has been a hypothesis that all raw asbestos fibers are encapsulated in solvents and binders and are not released as individual fibers if the material is cut or abraded. Examination of a number of different types of non-friable materials under the SEM show that after cutting or abrasion, tuffs or bundles of fibers are evident on the surfaces of the materials. When these tuffs or bundles are examined, they are shown to contain asbestos fibers which are free from binder material. These free fibers may be released into the air upon further cutting or abrasion.

The motion of molecular fragments in close contact with atomically flat surfaces is still not fully understood. Does a more favourable interaction imply a larger barrier towards motion even if there are no obvious minima? Here, we use mechanically interlocked rotaxane-type derivatives of SWNTs (MINTs) featuring four different types of macrocycles with significantly different affinities for the SWNT thread as models to study this problem. Using molecular dynamics, we find that there is no direct correlation between the interaction energy of the macrocycle with the SWNT and its ability to move along or around it. Density functional tight-binding calculations reveal small (<2.5 Kcal·mol-1) activation barriers, the height of which correlates with the commensurability of the aromatic moieties in the macrocycle with the SWNT. Our results show that macrocycles in MINTs rotate and translate freely around and along SWNTs at room temperature, with an energetic cost lower than the rotation around the C−C bond in ethane.<br>

Technological Tradition

In the Chinese technological tradition, no sector, apart from that of agriculture, is as rich in original ideas as naval architecture. Over the past three millennia, hundreds of different types of craft have been developed for use on China's shallow lakes, on its fast flowing rivers and along its often stormy coastal waters. Each type was developed for specific use as a means of transportation, and would seem to represent the ultimate answer to the challenges posed by local conditions. Ultimate answer, that is, within the limitations of the traditional building materials with which these boats were constructed and fitted out. Nor was ingenuity confined to construction techniques.

Operational Impact

The construction sector is one of the most energy-intensive in the industrialized countries. In order to limit climate change emissions throughout the entire life cycle of a building, in addition to reducing energy consumption in the operational phase, attention should also be paid to the embodied energy and CO2 emissions of the building itself. The purpose of this work is to review data on embodied energy and GWP derived from EPDs of different types of windows, to identify the LCA phases, the most impacting materials and processes from an environmental point of view and to perform a critical analysis of the outcomes. The results show a strong dependence on the typology of the frame, with wooden windows having competitive performances: lower average primary energy non-renewable (1123 MJ/FU), higher average primary energy renewable (respectively 817 MJ/FU) and lower global warming potential (54 kgCO2eq/FU). More transparency and standardization in the information conveyed by the program operators is, however, desirable for a better comparability of windows performances. In particular, the inclusion of the operational impact in the EPD is sporadic, but strongly important, since it can be the most impactful phase.

Material Porosity

The surfaces of building materials are constantly exposed to the actions of environmental factors, pollutants of inorganic and organic origin as well as to microorganisms, which significantly contribute to corrosion phenomena.The application of coatings decreases the negative action of the pollutants minimizing their direct contact with the substrate. Different types of coatings with additional functions have been developed. A specific problem of these applications is the lack of compatibility of the photocatalysts with the surface of the building materials and the detachment of potentially toxic TiO2nanoparticles. In the present study, this problem was solved by the proper immobilization of TiO2nanoparticles onto the photocatalyst support, layered double hydroxides (LDHs). The newly formed coating possesses acceptable porosity for a porous building material (porosity within the range of 30-46 %) and satisfied photocatalytic activity, as well as mineralogical compatibility with the substrates (mortars, renders, bricks). Additionally, a positive effect considering the self-cleaning phenomenon was attained.
