The effects of the implemented CSUD features on the existingmasterplanningThe climate-sensitive planning for the Heidestrasse/Europacity intendedto bring valuable suggestions aiming to tackle the problematic,ahead of the appointed “Sustainability Workshop Buildings” in 2011.“The master plan was not conceived as a rigid, restrictive set of rulesand regulations” (SenStadt 2009, p. 11) and welcomes detailed considerationstowards climate-sensitive design. Thus, the planning suggestedin this Thesis has been understood as an adjustment of theexisting urban design proposal and has brought a number of interestingconclusions:The urban form, with the exception of a few minor adjustments, remainsas in the original proposal, for it is as such conforming to the appointedclimate-sensitive design characteristics. The main Heidestrasseartery’s proportions as well as the original urban block structure remain.There has however been a change in the height dispersion ofthe buildings for improving turbulent ventilation conditions, althoughwithout significantly influencing the overall urban density. The urbanblocks furthermore gain openings for better local air circulation andwind penetration; and local additions in the number of storeys do notonly enhance the desired turbulent ventilation but also (as a positiveside-effect for the developer) balance out the loss of the floor space.The main input regarding the urban form is thus in strengthening oflocal circulation and general wind conditions. The other, not less significantcomplementation lies in the decentralized rainwater managementand in the accentuation of vegetating measures. The main mean is thesurface design in the open space as well as on the buildings.Fig. 92/P17 Proposed CSUD conceptFig. 93/P48 Proposed street and courtyardprofile of the residential areaPlan flat vegetated roofsthat have cooling effectthrough evapotranspirationand can be combined withphotovoltaic systemsUse façade vegetation onevery vertical built surface(except windows).Provide parkinglots with vegetatedpergolas and withpermeable pavingElevate privategardens abovethe parking lotaccess roadUsepermeablepavementmaterialsReduce ceiling’s height to2.6 m for more efficientuse of space (morestoreys fit onto smallerground space)Design pebble/soil stripes alongthe façades toenable buildings’greeningInvolve vegetatedswales for rainwaterevapotransirationand infiltration witha min. width of 2 m.Reduce the street widthto the minimum ofthe required width forautomobile traffic in theopposite direction (4 m).Use semipermeablesurfaces forroads, sidewalksand parking lots.Collect theinfiltratedrainwater forre-use with anoverflow drain3 Climate Sensitive Urban Design (CSUD) in moderate climate zone57
4 ConclusionsBased on the need to address the climate-related problems in – and caused by – citieswith the help of urban design, this Thesis aimed to review the literature that brings recommendationsand guidelines addressing extreme heat conditions in moderate climatecities; and to use the findings as a base for a set of Climate-Sensitive Urban DesignGuidelines.The Thesis summarized the climatic features of cities, being dry and hot and thus havingthe effect of “concrete deserts” (that are accepted even within many “sustainable”developments). Throughout the world, there are researchers and designers addressingthis issue. Among them, Givoni (1998) and Emmanuel (2005) are considered the mostauthorative sources for urban designers. The review however showed that while focusingon the urban form and geometry, these sources do not address in depth the environmentalaspects of urban climatic considerations – the issues of energy flows and watercycle; and additionally avoid suggesting particular recommendations for designing inmoderate climates. Other sources focus well on the environmental processes in cities,such as the climatic aspects of energy flows and water cycles (Sukopp and Wittig 1998;Kravčík et al. 2007; Marzluff 2008); these sources however omit particular design recommendations.This gap, fortunately, is filled by other valuable sources that address thenatural water cycle and energetic processes – particularly by guidelines implemented byvarious cities (Chicago 2003, NYC 2007, Berlin 2010).Referring to the reviewed sources, this Thesis aimed at a connection of the main streams– the “environmental” and “architectonical” – in understanding the climatic aspects ofthe built form of cities. The main legacy is: Learn from nature, where the streams ofwater and ventilation are unobstructed (fig. 94).Fig. 94 Diagram of energy flows, water andwind in an idealized urban environment58Climate Sensitive Urban Design in Moderate Climate Zone: Responding to Future Heat Waves.
