Cubiertas Verdes - HIDROTECHUSA

The landscape possibilities with intensive green roofs are virtually limitless. They are intended for recreational, sporting and leisure purposes and are often indistinguishable from natural gardens in appearance. Hydrotech’s Lawn and Intensive Garden Roof® Assemblies follow the same design concept as an extensive Garden Roof. However, the drainage/retention layer is usually deeper and filled with expanded aggregate to provide greater water storage and to support a greater depth of growing media. The depth of the intensive growing media, which contains a greater amount of organic matter than an extensive blend, will generally dictate the type and size of plants that can be grown.
Intensive green roof designs usually consist of a mixture of hard and soft landscaping. It is therefore important that the selected drainage/retention layer can support any type of landscape – from roadways and paths, to soil and trees, so as to permit excess water to drain unobstructed underneath. The water retention capacity of the Hydrotech drainage/retention layers is used to assist with the irrigation of the plants – it is not a substitute for an irrigation system, which should always be installed within either the intensive or lawn Garden Roof Assembly.
Features:
Require greater growing media depths 6”-36”
Can be used for recreation
Accommodate a wider variety of plants/shrubs/trees
Must be irrigated
Require regular maintenance

Autodesk Green Building Studio

Impresionante aplicacion, que combinada con Revit2009 produce un analisis online de las caracteristicas Sustentables de un proyecto.

Overview
Using the Autodesk® Green Building Studio® web-based energy analysis service, architects and designers can evaluate how building components impact energy consumption, and improve a project’s economic and environmental performance early in the design process.
Compatible with the Revit Platform
Autodesk Green Building Studio—facilitating team collaboration and information sharing—interoperates with Revit® Architecture and Revit® MEP software, as well as other compatible energy-analysis software. Subscribers can now directly access the web service from within the Revit platform for BIM using a plug-in that is available for download from the Green Building Studio web service.
Learn how to get started
Evaluate Energy Profiles of Building Designs
Green Building Studio tools enable architects and designers to evaluate the energy profiles and carbon footprints of their building designs early in the design cycle. Files can be shared between engineering software programs, and among engineers and architects, making sustainable design more efficient, and cost effective.
Capabilities of Green Building Studio Tools
Capture early sustainable design analysis to support the process of reducing negative environmental impacts
Communicate among the extended building design team using Autodesk design applications, and other compatible energy and green analysis software
Help gain a competitive advantage with increased client satisfaction and improved environmental performance

ebook Cultivando Mejores Ciudades

Cultivando Mejores Ciudades

This is the Spanish edition of " Growing Better Cities". The United Nations predicts that over the next 25 years nearly all population growth will be in the cities of the developing world. At current rates, 60% of the world's total population will live in cities by 2030. As the cities grow, so does the number of urban poor. Unemployment, hunger, and malnutrition are commonplace. In the big city, most of any cash income the poor might bring home goes to feeding themselves and staying alive; any food that does not have to be bought is a bonus. As a result, more and more people are attempting to grow at least some of their own food to supplement poor diets and meager incomes. But farming in the city - urban agriculture - is too often seen by municipalities as a problem to be eradicated rather than as a part of the solution to making the city and its environment more sustainable. In fact, urban agriculture has a long history. Throughout the developing world, municipal policymakers are waking to the fact that properly managed agriculture can make a major contribution to a city's food security. It also has potential to provide employment, improve the environment, and make productive use of vacant spaces within the city. More than 20 years ago, IDRC became the first international agency to formally support research on urban agriculture. This book reviews the research experience of IDRC and its partners, including local governments, into the issues surrounding urban agriculture, with a particular emphasis on the influence that research has had on government policies. It describes the growth of city networks in Africa and Latin America that focus on accommodating urban agriculture and improving the lot of urban food producers. And it offers specific recommendations aimed at helping policymakers at all levels of government to maximize the potential of urban agriculture. The book concludes with a vision of how such policies might transform cities in the near future. This book serves as a focal point for an IDRC thematic Web site on urban agriculture: www.idrc.ca/in_foucus_cities. The full text is available online and leads the reader into a virtual web of resources that explores two decades of research into this important issue.
