Urban designUrban design is an approach to the design of buildings and the spaces between them that focuses on specific design processes and outcomes. In addition to designing and shaping the physical features of towns, cities, and regional spaces, urban design considers 'bigger picture' issues of economic, social and environmental value and social design. The scope of a project can range from a local street or public space to an entire city and surrounding areas.
Ceinture verte (urbanisme)En urbanisme, une ceinture verte est une zone entourant une ville où l’urbanisation est interdite afin d’empêcher l’étalement urbain. Le concept a été créé au Royaume-Uni durant la première moitié du sous le nom anglais green belt. Bruxelles est entourée par la ceinture verte de Bruxelles Ceinture verte de Bruxelles Le concept est appliqué au Canada à partir des années 1950 pour la capitale, Ottawa, et prend la dénomination de « ceinture de verdure ».
Green urbanismGreen urbanism has been defined as the practice of creating communities beneficial to humans and the environment. According to Timothy Beatley, it is an attempt to shape more sustainable places, communities and lifestyles, and consume less of the world's resources. Urban areas are able to lay the groundwork of how environmentally integrated and sustainable city planning can both provide and improve environmental benefits on the local, national, and international levels.
ElastanceElectrical elastance is the reciprocal of capacitance. The SI unit of elastance is the inverse farad (F−1). The concept is not widely used by electrical and electronic engineers. The value of capacitors is invariably specified in units of capacitance rather than inverse capacitance. However, it is used in theoretical work in network analysis and has some niche applications at microwave frequencies. The term elastance was coined by Oliver Heaviside through the analogy of a capacitor as a spring.
