Lightweight Landscape: Enhancing Design through Minimal Mass by Alessandra Zanelli, Luigi Spinelli, Carol Monticelli, Paolo

By Alessandra Zanelli, Luigi Spinelli, Carol Monticelli, Paolo Pedrali

This publication explains how light-weight fabrics and buildings may be deployed in constructions to satisfy excessive environmental and aesthetic criteria and emphasizes how the concept that of lightness in construction expertise and layout dovetails with the will to augment panorama. the 1st a part of the e-book, on light-weight building, goals to foster using membranes in the particular climatic context and specifically considers how light-weight fabrics and cutting edge applied sciences can increase the standard of transitority areas. the second one half focuses completely on panorama, featuring novel ways within the look for visible lightness and the hunt to enhance city areas. specific realization is paid to the Italian event, the place the conventional appreciation of brick and stone has restricted the scope to be used of light-weight buildings and membrane fabrics, usually relegating them to a secondary or beside the point function. The reader will come to understand how this perspective demeans a truly complicated effective area and neglects the traditional culture of transitority structure.

Urban Sprawl in Europe: Landscape, Land-Use Change and Policy

City sprawl is likely one of the most crucial different types of land-use adjustments at present affecting Europe. It more and more creates significant affects at the setting (via floor sealing, emissions via delivery and environment fragmentation); at the social constitution of a space (by segregation, way of life alterations and neglecting city centres); and at the financial system (via dispensed creation, land costs, and problems with scale).

Handbook of Research on Public Information Technology

Using details expertise within the public area has been an more and more trendy overseas development. With this swift growth comes many matters, demanding situations, and matters with regards to the appliance of public info know-how. The guide of analysis of Public details know-how compiles estimable learn at the international pattern towards the speedily expanding use of knowledge expertise within the public zone, discussing such concerns as e-government and e-commerce; venture administration and knowledge know-how overview; method layout and knowledge processing; defense and safety; and privateness, entry, and ethics of public details know-how.

Example text

Buckminster Fuller, 1949. 4 A. Zanelli Soft Materials, Adaptive Skins There is a real need to learn about these special materials that are so lightweight and deformable. However, if these special materials are used badly and in a makeshift manner, then one can cause more damage than using traditional materials. In the best scenario, one doesn’t achieve the desired lightness for the design; while in the worst scenario, the structure simply doesn’t stay up or collapses straight away. Some key points that help to fully understand the specific nature of textile architecture – using textile materials properly and as efficiently as possible – are: first, the best use of the chosen material; second, the volume and layout is suited to the chosen function; third, the structural conception is effective and fully consistent with the proposed architectural form.

During a famous interview he said: “One of the most important things you should do in a school of architecture is that every student when designing or drawing should make a list of all functional requirements and also materials and resources that are employed, in order to figure all the weights, amount of energy, amount of time; all of these must be on the drawing, every time, every drawing. As we do with the aeroplane, we know everything of its performances. The designers must be responsible for technology itself, where the resources are coming from, and how we get them… the designers must be responsible from beginning to end” (Pettena 1975, 1978).

Fig. 7 A case of a seasonal structure designed for the summer, which offers shade and shelter from heat radiation, El Cairo, Egypt (Source Zanelli 2007) 3 Lightweight Materials and Environmental Quality Requirements 37 A number of important design strategies may be identified by considering a building’s permanent or temporary nature from a lifestyle thinking approach: – For “permanent” buildings, more attention must be paid to the operational phase (energy requirements for heating and cooling, maintenance), including the need for more envelope insulation, greater mass, more materials, and consequently a greater environmental impact during production processes; consideration of what material and technological solutions to choose and their environmental impacts takes place subsequently.
