Architecture today

Main article: Contemporary architecture

 

Gare do Oriente Railway Station, Lisbon, by Santiago Calatrava.

Part of the architectural profession, and also some non-architects, responded to Modernism and Postmodernism by going to what they considered the root of the problem. They felt that architecture was not a personal philosophical or aesthetic pursuit by individualists; rather it had to consider everyday needs of people and use technology to give a livable environment. The Design Methodology Movement involving people such as Christopher Alexander started searching for more people-oriented designs. Extensive studies on areas such as behavioral, environmental, and social sciences were done and started informing the design process.

As the complexity of buildings began to increase (in terms of structural systems, services, energy and technologies), architecture started becoming more multi-disciplinary. Architecture today usually requires a team of specialist professionals, with the architect being one of many, although usually the team leader.

During the last two decades of the twentieth century and into the new millennium, the field of architecture saw the rise of specializations by project type, technological expertise or project delivery methods. In addition, there has been an increased separation of the 'design' architect [a] from the 'project' architect.[b]

Moving the issues of environmental sustainability into the mainstream is a significant development in the architecture profession. Sustainability in architecture was pioneered in the 1970s by architects such as Ian McHarg in the US and Brenda and Robert Vale in the UK and New Zealand. There has been an acceleration in the number of buildings which seek to meet green building sustainable design principles.

It is now expected that architects will integrate sustainable principles into their projects.[19]

The American Institute of Architects acknowledges that half of today's global warming greenhouse gas emissions come from buildings - more than transportation or industry.[20] AIA states that immediate action by the building sector is essential to avoid hazardous man-made climate change. They have an "Architecture 2030" plan[21] to reduce new building energy consumption by 90% in 2030, and net zero greenhouse gas emissions by 2035. Passive solar building design has been demonstrating essential elements of 70% to 90% energy consumption reduction in roughly 300,000 buildings since the 1978 U.S. Solar Energy Tax Incentives. Many of these energy efficiency features can be added at little-or-no additional net cost during construction. Newer zero energy buildings have reduced net annual energy consumption, producing excess energy and selling it back to the power company during moderate months. The demand for zero energy buildings is growing rapidly - subsidies are available for this type of building[22] - The supply of zero energy buildings has fallen far short of current demand. Off-the-grid buildings are now demonstrating total self sufficiency. The 2009 Bank of America Tower (New York) has many innovative energy features.

President George W. Bush’s 2006 Solar America Initiative expects architects and builders to design and construct new zero energy buildings by 2015.[23] The U.S. Energy Independence and Security Act of 2007[24] funded the new Solar Air Conditioning Research and Development Program, to develop technology innovations and mass production economies of scale. The U.S. Department of Energy and the National Renewable Energy Laboratory (NREL) also sponsor The Solar Decathlon,[25] an international competition among universities for solar energy alternatives when it comes to houses. The houses built by the team are exhibited on the National Mall for the public to experience.

Abstract

SiOC and SiZrOC ceramics were obtained starting from the hydrosilane system without and with zirconium n-propoxide (Zr(OnPr)4) by sol–gel route. The precursor architectures indicated that the presence of Sisingle bondH bonds leads to a different cross-linking mechanism of SiZrOC precursor, where the Sisingle bondH bonds were involved in the formation of Sisingle bondOsingle bondZr bonds. The presence of Zr caused a lower content of sp3 carbon in SiZrOC ceramics. At above 1400 °C, the sp3-C/Si ratio in both ceramics increased due to carbothermal reduction, especially rapidly for SiOC ceramics, suggesting the carbothermal reduction in SiZrOC ceramics has been strongly suppressed with the presence of ZrO2. Raman spectroscopy showed the graphitization degree of free carbon increased with temperature in both ceramics, but was always lower in SiZrOC ceramics. The SiZrOC ceramics has been found to exhibit remarkably high temperature stability with respect to carbothermal decomposition up to 1600 °C in comparison with the SiOC ceramics.

Seismic architecture, stratigraphy and evolution of a subtropical marine embayment: Maputo Bay, Mozambique

Abstract

The seismic stratigraphy, architecture and evolution of a large subtropical embayment, Maputo Bay, Southern Mozambique is described. Nine seismic units are documented; and show repeated phases of incised valley formation and transgressive infilling. Trangressive infilling alternates between the classic wave-dominated transgressive succession of fluvial and central estuarine bay deposits and the filling by intertidal flat and tidal bedforms developed during stages of inlet restriction and shallowing associated with barrier growth at stillstand intervals. Imprinted on the succession are several key facets of subtropical stratigraphy, hurricane-generated erosional surfaces and beachrock horizons. The upper stratigraphy comprises the highstand bayhead delta, a prograding feature constructed by several flood events. In comparison with literature from other similar systems such as lagoons, coastal lakes and estuaries, a generic three stage stratigraphic model of large marine embayments is proposed that includes incisionduring glaciations; transgressive infilling during deglaciations; and shallowing during thestillstand episodes of the recent deglaciation.
