The newly released book Sustainable Urban Environments - An Ecosystem Approach ‘helps the reader grasp opportunities for integration of knowledge and technologies in the design, construction and management of the built environment.’ In the first edition of the Delft Environment Initiative Lecture Series on 21-09-2011 several contributors to Sustainable Urban Environments discussed their views on the most pressing challenges facing us in the urban environment today and how they should be integrated in education. These are the slides accompanying the ‘elevator pitches’ they gave. http://home.tudelft.nl/en/research/environment/mini-symposium-sustainable-urban-environments/
8. Chapter 2(Eco)system thinking: ecologicalprinciplesfor buildings, roads, industrialandurbanareas Hein van Bohemen Former lecturer Ecological Engineering At present: EcoEngineeringConsultancy
9. Passion for Ecoengineering Integration of civil and ecological engineering (example roads in the landscape, green roofs and green façades) Based on EcoSystemThinking (inspiration: H.T.Odum, William Mitsch and John Todd) Realization of Value for humans as well as for nature
13. Challenge: Realizationof full integration of as many aspects (env., ecol., econ. ,social, cultural) as possible on all levels of scalesbased on symbioticrelationshipbetween humans andtheirnatural environment
14. Chapter 3Urban ecology, scale and identity Prof.dr.ir. Taeke M. De Jong motivation: ‘Architecture is a kind of ecology, design is differentiation’
15. Differentiation is a risk cover for life The number of plant species per km2 in Zoetermeer is related to its physical diversity The more physicaldiversity, the more species willfind a fitting place
18. Identity is difference with the rest and continuity in itself What is the difference with other regions? (30km radius) What is the difference with other conurbations? (10km) What is the difference with other townships? (3km) What is the difference with other districts? (1km) What is the difference with other neighbourhoods? (300m) What is the difference with other ensembles? (100m) Anyone looking for a location will ask such questions, Designers have to answer them.
19. Built environment Chapter 6 Sustainable Urban Metabolism_ Towards use of resources design strategies and constructive solutions Loriane M. Icibaci PhD research Roughly 75% of waste is land filled Average within the European Union 25% of the waste is recycled (however, Denmark, the Netherlands and Belgium already achieved recycling rates of more than 80%). Building industry is one of the largest consumers of natural resources_average40% (Kibert 2002). Most of the considered dangerous waste is not always separated from other forms of waste and thus contaminate land fills or recycled inert wastes (European Commission 2000). Nearly three tons used annually for each person on the planet. (WBCSD 2002) Cement industry contributes to about 5% to global anthropogenic CO2emissions_____50% is from the chemical process_______40% from burning fuel ______10% electricity and transport (WBCSD 2002; (Worrell et al. 2001). Cement manufacturing requires mainly mineral extraction from quarries (besides water and energy for its production).
20. Dutch building LCA Sustainable Urban Metabolism_ Towards use of resources design strategies and constructive solutions Loriane M. Icibaci PhD research Level of building decree (EBI 200) High Tech building (EBI 500) Energy Neutral building (EBI 1000) A building considered to be sustainable according to Dutch regulations in 2010 [equivalent to an Environmental Building Index (EBI). A building in which high-tech methods have been used to radically reduce energy consumption (equivalent to an EBI of 500). An energy-neutral building (equivalent to an EBI of 1,000) which has no environmental impact in terms of energy. Haas 2009
21. Urban Metabolism_ studies illuminate basic trends in human energy and material fluxes. Sustainable Urban Metabolism_ Towards use of resources design strategies and constructive solutions Loriane M. Icibaci PhD research Decker et al. (2000) More self reliant By mapping flows of materials it is possible to propose closed loop solutions leading to less input/ and less output leading to more efficient and therefore a more self sufficient urban structure. Integrated solutions Combining flows of materials with different coefficients and indicators of a city-region requires consideration of the complex interactions between economic, environmental, and social factors. Support for future prognostics Caring capacity estimated through time line; avoiding exhaustion of materials and consequent region decay. Detects consumer, households, industrial and commercial behavior and consequences. Intra and interrelationships among other regions (resource dependency or waste dependency). Pollution prevention (from cars or industrial activities, etc.) Food and water security. Diagnosis As a living organism, it is assumed that by using UMM it is possible to detect pathologic cycles, environmental, and even economic.

43. Using a high efficiency condensing boiler is non-sense?Then read Chapter 5: Energy in the built environment
44. Urban transport and sustainability Bert Van Wee – DUT Perspective: transport is fantastic, but comes at high costs. What is ‘good’ policy? Difficult, but very challenging and important question

Hinweis der Redaktion
Make use of local opportunitiesSignificantly reduce resource flows (and reuse)Look for synergies, also in connection with agricultureIn collaboration with people living in the area and actors (public and private) deciding on the area
Built environment requires bulk amounts of material. A large chain of problems is affected by such demand during its life cycle such as transport, land use, biodiversity, toxicity, material scarcity
Through Urban Metabolism Models, building materials is on the top relevant material flows in every urbanized area together with energy, water and food items.
The bigger art of the Randstad consists of the Dutch lowlands are below seal level, excepting the natural rivers. But why are the Dutch lowlands so low. The following slides will give you explanation.
