Bipolarity and Ambivalence in Landscape Architecture
Our discipline of landscape architecture contains bipolarity, not only in terms of landscape and architecture but also because the idea of landscape is both aesthetic and scientific. Furthermore, within landscape architecture there is a gap between design (as implied by architecture) and planning (implying land-use plan and policy orientation) on one hand, and a similar gap between design (associated with artistic activity, concerned with aesthetics as well as science) and research (considered as scientific activity Landscape architects often retain as much ambivalence between design and planning, as they do between design and research
Shifting Core and Slipping Foundation: An Uncertain Future of Landscape Architecture in European Universities
Faced with the dual and often conflicting necessity to be scientific and design practices the discipline of landscape architecture today is challenged to re-examine its core and intellectual foundation. There is a growing trend toward design as reflective practice. The discipline is maturing and needs autonomous theories and methods. Global and social externalities favor attention to landscape and landscape-based design. Landscape is not only an integrative and evolving concept and practice but also a trans-disciplinary cultural concern. Under such circumstances the core of landscape architecture is shifting and its intellectual foundation is questione
On a landscape approach to design and eco-poetic approach to Landscape
For Landscape Architecture to become an academic discipline it must present its own coherent theory and methodology for the planning, designing and management of (built) landscapes. This also requires not only an articulated if difficult differentiation of planning, design and management and the interrelationship between them, but also clarification of the term landscape itself
Sustainable energy transition: properties and constraints of regenerative energy systems with respect to spatial planning and design
Before transforming the built environment, one must understand the characteristic of regenerative systems. The aim of this study was is to compare fossil-fuel energy systems with regenerative systems. It explores key properties and constraints of regenerative energy systems with respect to spatial organization and design of the built environment. The findings of this comparative analysis are illustrated with the help of a regional case-study in South Limburg, the Netherlands
Thermal conductivity and electrical resistivity of porous materials
Process for determining thermal conductivity and electrical resistivity of porous materials is described. Characteristics of materials are identified and used in development of mathematical models. Limitations of method are examined
Wind and solar powered turbine
A power generating station having a generator driven by solar heat assisted ambient wind is described. A first plurality of radially extendng air passages direct ambient wind to a radial flow wind turbine disposed in a centrally located opening in a substantially disc-shaped structure. A solar radiation collecting surface having black bodies is disposed above the fist plurality of air passages and in communication with a second plurality of radial air passages. A cover plate enclosing the second plurality of radial air passages is transparent so as to permit solar radiation to effectively reach the black bodies. The second plurality of air passages direct ambient wind and thermal updrafts generated by the black bodies to an axial flow turbine. The rotating shaft of the turbines drive the generator. The solar and wind drien power generating system operates in electrical cogeneration mode with a fuel powered prime mover
Fundamental study of transpiration cooling
Isothermal and non-isothermal pressure drop data and heat transfer data generated on porous 304L stainless steel wire forms, sintered spherical stainless steel powder, and sintered spherical OFHC copper powder are reported and correlated. Pressure drop data was collected over a temperature range from 500 R to 2000 R and heat transfer data collected over a heat flux range from 5 to 15 BTU/in2/sec. It was found that flow data could be correlated independently of transpirant temperature and type (i.e., H2, N2). It was also found that no simple relation between heat transfer coefficient and specimen porosity was obtainable
Dreijen Regeneration Study: Professional Academy 2007
This year the students of the “Professional Academy”, a combined theory and design class in landscape architecture, elaborated on a vision on the campus “de Dreijen” in Wageningen. This campus will be left by the university within the coming decade, university functions mainly moving towards the new campus “de Born” in the North of the city. Their “research by design” study brought about very different visions, but they all reflected the main theories learnt about urban sustainability and ecolog
Ancient Organic Residues as Cultural and Environmental Proxies: The Value of Legacy Objects
Often treated as an accessory science, organic residue analysis (ORA) has the capacity to illuminate otherwise hidden aspects of ancient technology, culture, and economy, and therein can play a central role in archaeological inquiry. Through ORA, both the intact vessel freshly excavated from a tomb and the sherd tucked away in a museum storage closet can offer insights into their contents, their histories, and the cultures that created them—provided the results can be carefully calibrated to account for their treatment during and after excavation. The case study below presents ORA data obtained from a range of artifacts from Late Bronze Age Crete, setting results from freshly-excavated and legacy objects alongside one another. Although legacy objects do tend to yield diminished results from both a quantitative and qualitative perspective, our comparative work has demonstrated both their value and untapped potential when their object biographies are carefully considered. It also sheds light on biomarker degradation processes, which have implications for methodologies of extraction and interpretation of legacy objects. Comparative studies such as these broaden the pool of viable ORA candidates, and therein amplify ORA’s ability to reveal patterns of consumption as well as ecological and environmental change. They also highlight the role and value of data-sharing in collaborative environments such as the OpenARCHEM archaeometric database.
