Tecla House
The Tecla house is a prototype 3D-printed eco residential building made out of clay. The first model was designed by the Italian architecture studio Mario Cucinella Architects (MCA) and engineered and built by Italian 3D printing specialists WASP by April 2021, becoming the world's first house 3D-printed entirely from a mixture made from mainly local earth and water. Its name is a portmanteau of "technology" and "clay" and that of one of Italo Calvino's Invisible Cities whose construction never ceases. History The project was reportedly first conceived by WASP Founder Massimo Moretti and, via research of the Cucinella-founded training center School of Sustainability (SOS), MCA's founder Mario Cucinella. For construction, WASP's 3D printing technology ''Crane WASP'' was used. This 3D printer was used for the similar building "GAIA" – the first 3D printed earth building – completed in 2018, about 7 years after WASP's inception in 2012. Printing started in September 2019.

G-code
G-code (also RS-274) is the most widely used computer numerical control (CNC) programming language. It is used mainly in computer-aided manufacturing to control automated machine tools, and has many variants. G-code instructions are provided to a machine controller (industrial computer) that tells the motors where to move, how fast to move, and what path to follow. The two most common situations are that, within a machine tool such as a lathe or mill, a cutting tool is moved according to these instructions through a toolpath cutting away material to leave only the finished workpiece and/or an unfinished workpiece is precisely positioned in any of up to nine axes around the three dimensions relative to a toolpath and, either or both can move relative to each other. The same concept also extends to noncutting tools such as forming or burnishing tools, photoplotting, additive methods such as 3D printing, and measuring instruments.

Homelessness
Homelessness or houselessness – also known as a state of being unhoused or unsheltered – is the condition of lacking stable, safe, and adequate housing. People can be categorized as homeless if they are: * living on the streets, also known as rough sleeping (primary homelessness); * moving between temporary shelters, including houses of friends, family, and emergency accommodation (secondary homelessness); and * living in private boarding houses without a private bathroom or security of tenure (tertiary homelessness). * have no permanent house or place to live safely * Internally Displaced Persons, persons compelled to leave their places of domicile, who remain as refugees within their country's borders. The rights of people experiencing homelessness also varies from country to country. United States government homeless enumeration studies also include people who sleep in a public or private place, which is not designed for use as a regular sleeping accommodation for hu ...

Environmental Impact Of Concrete
The environmental impact of concrete, its manufacture and applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO2 emissions; between 4-8% of total global CO2 emissions come from concrete. Many depend on circumstances. A major component is cement, which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas. Concrete causes damage to the most fertile layer of the earth, the topsoil. Concrete is used to create hard surfaces which contribute to surface runoff that may cause soil erosion, water pollution and flooding. Conversely, concrete is one of the most powerful tools for proper flood control, by means of damming, diversion, and deflection of flood waters, mud flows, and the like. Light-colored concrete can reduce the urban heat island effect, due to its higher albedo. However, original vegetatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automation In Construction
Automation in construction is the combination of methods, processes, and systems that allow for greater machine autonomy in construction activities. Construction automation may have multiple goals, including but not limited to, reducing jobsite injuries, decreasing activity completion times, and assisting with quality control and quality assurance. Some systems may be fielded as a direct response to increasing skilled labor shortages in some countries. Opponents claim that increased automation may lead to less construction jobs and that software leaves heavy equipment vulnerable to hackers. Transportation Construction Kratos Defense & Security Solutions Kratos Defense & Security Solutions, Inc, (), headquartered in San Diego, California, is an American technology company specializing in directed-energy weapons, unmanned systems, satellite communications, cyber security/warfare, microwave electro ... fielded the world’s first Autonomous Truck-Mounted Attenuator (ATMA) in 2017, ...

Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability ( resistance value). In thermal engineering, other important properties of insulating materials are product density (ρ) and specific heat capacity (c). Definition T ...

Accessible Housing
Accessible housing refers to the construction or modification (such as through renovation or home modification) of housing to enable independent living for persons with disabilities. Accessibility is achieved through architectural design, but also by integrating accessibility features such as modified furniture, shelves and cupboards, or even electronic devices in the home. Canada In Canada, Flexhousing is a concept that encourages homeowners to make renovations that modify their house over time to meet changing accessibility needs. The concept supports the goals of enabling "homeowners to occupy a dwelling for longer periods of time, perhaps over their entire lifetimes, while adapting to changing circumstances and meeting a wide range of needs"; Universal Housing in the United States and Lifetime Homes in the United Kingdom are similar concepts. United Kingdom Great Britain applies the most widespread application of home access to date. In 1999, Parliament passed Section M, an ame ...

Migrant Crisis
Migrant crisis is the intense difficulty, trouble, or danger situation in the receiving state (destination country) due to the movements of large groups of immigrants (displaced people, refugee or asylum seeker) escaping from the conditions (natural or refugees as weapons, artificially created) which negatively affected their situation (security, economic, political or societal) at the country of origin (departure). The "crisis" situation is not the refugee numbers (number of migrants seeking protection) but the system's failure to respond in an orderly way to the government's legal obligations. Some notable crises are; European migrant crisis, English Channel migrant crisis and World War II evacuation and expulsion. A refugee crisis refers to a movement of "large" groups of displaced people, and may or may not involve a migrant crisis. The United States, US government's legal obligations inadvertently created the 2014 American immigration crisis. The crisis developed because of una ...

Effects Of Climate Change
The effects of climate change impact the physical environment, ecosystems and human societies. The environmental effects of climate change are broad and far-reaching. They affect the water cycle, oceans, sea and land ice (glaciers), sea level, as well as weather and climate extreme events. The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions. The regional changes vary: at high latitudes it is the average temperature that is increasing, while for the oceans and tropics it is in particular the rainfall and the water cycle where changes are observed. The magnitude of future impacts of climate change can be reduced by climate change mitigation and adaptation. Climate change has degraded land by raising temperatures, drying soils and increasing wildfire risk. Recent warming has strongly affected natural biological systems. Species worldwide are mig ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Green Building
Green building (also known as green construction or sustainable building) refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages.Yan Ji and Stellios Plainiotis (2006): Design for Sustainability. Beijing: China Architecture and Building Press. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient u ...

Timelapse Of 3D-printer Construction Of The Clay House "Tecla" V1
Time-lapse photography is a technique in which the frequency at which film frames are captured (the frame rate) is much lower than the frequency used to view the sequence. When played at normal speed, time appears to be moving faster and thus ''lapsing''. For example, an image of a scene may be captured at 1 frame per second but then played back at 30 frames per second; the result is an apparent ''30 times'' speed increase. Similarly, film can also be played at a much lower rate than at which it was captured, which slows down an otherwise fast action, as in slow motion or high-speed photography. Processes that would normally appear subtle and slow to the human eye, such as the motion of the sun and stars in the sky or the growth of a plant, become very pronounced. Time-lapse is the extreme version of the cinematography technique of ''undercranking''. Stop motion animation is a comparable technique; a subject that does not actually move, such as a puppet, can repeatedly be m ...
