Abstract This paper addresses the limitations of existing Solar Envelope (SE) methods to explore the trade-offs of solar radiation and urban shading, and to simultaneously account for several different Key Performance Indicators (KPIs). It offers an alternative parametric workflow - the Solar Block Generator (SBG) - which is based on an additive voxelization method by which multiple solar-driven massing alternatives are generated and evaluated for a given site, corresponding to a set of user-defined environmental KPIs. This method is tested here on an urban redevelopment case study in the Mediterranean (Tel Aviv). The results help achieve a more holistic approach for solar driven urban design.

The coleorhiza is a nonvascular sheath that encloses the embryonic radicle in Poaceae, and is generally the first tissue to emerge during germination. Delicate hairlike extensions develop from some coleorhiza cells prior to radicle emergence. Similar to root hairs, coleorhiza hairs are extremely sensitive to desiccation and are damaged by exposure to negative water potentials. The coleorhiza of Lolium perenne is somewhat spherical when first visible, after which a knob forms at a right angle to the caryopsis due to inner pressure from the elongating radicle. This knob increases in length until the radicle finally punctures the coleorhiza. Standard fixation procedures cause severe desiccation of coleorhiza cells and hairs, making morphological study of the coleorhiza difficult. This study was conducted to determine a more successful process for coleorhiza preservation.

The debate about the so called “excluding design” has been a focus for applied philosophy for several years. The structure of this debate is constituted by deontological and consequentialist’s applied ethics and as well as agonistic democratic approaches. This paper asks for the applicability of these points of view to the particular socio-political reality of Montevideo. Examining this reality closer, I hold that we cannot comprehend the recent aestheticization of the excluding design there through these contemporary philosophical frameworks. As an alternative philosophical procedure, I analyze the aestheticization of excluding design in Montevideo from Rahel Jaeggi’s immanent criticism. I hold that this process of aestheticization implies an ideological regressive “form of life”. And I also argue that the Uruguayan democracy is affected by this ideological regression. Nevertheless, because this aestheticization is not an exclusive Uruguayan phenomenon, this paper intends to open one direction in applied philosophy of urban design.
