We solve such problems iteratively by proposing a solution, analysing it and testing its suitability until the solution satisfies all conditions and objectives. Normally we solve such problems based on experience and knowledge, which does not work for the problems we are confronted with for the first time. An alternative approach is generative design, where we focus on defining a problem with its objectives and constraints in terms of a parametric computational model and leave the solution to the algorithms. The result of the generative process is a set of solutions the analysis of which helps us to solve the problem. The main idea of the approach is the collaboration between the designer and the intelligent tool, which has complementary capabilities, such as sorting large amounts of data, generating many alternatives, analysing the solutions, and incrementally improving them. The approach is general and can also be applied in other areas of civil engineering. In this paper, we question the capacity of such an approach and whether it aims to replace the designer in the design process. Therefore, in the first part we present the key elements of generative design, in the second part we apply the generative design process for the design of shading elements, and in the last part we present the results and compare them with the usual approachPri načrtovanju se velikokrat srečamo s problemi, za katere moramo določiti ustrezno rešitev. Takšne probleme običajno rešujemo iterativno (predpostavimo rešitev, jo analiziramo in preverimo ustreznost, dokler rešitev ne zadosti vsem pogojem in ciljem) na podlagi izkušenj in znanja, kar pa ne deluje pri problemih, s katerimi se soočimo prvič. Alternativni pristop je generativno načrtovanje, kjer se osredotočimo na definiranje problema s pripadajočimi cilji v obliki parametričnega računskega modela, ki ga prepustimo v reševanje algoritmom. Ti na podlagi optimizacijskih metod iščejo ustrezne rešitve glede na podane kriterije in omejitve. Rezultat generativnega postopka je množica rešitev, ki nam z ustrezno analizo pomagajo učinkovito rešiti zastavljen problem. Glavna ideja pristopa je sodelovanje projektanta z inteligentnim orodjem, ki ima komplementarne sposobnosti: pregled velikega števila podatkov, generiranje velikega števila alternativ, analiza množice in iterativno izboljšanje rešitev. Pristop je splošen in zato uporaben pri načrtovanju na vseh področjih gradbeništva. V prispevku se vprašamo o zmogljivosti takega pristopa in če ta vodi k nadomestitvi projektanta v procesu načrtovanja. Tako v prvem delu predstavimo ključne dele generativnega načrtovanja in njihovo delovanje, v drugem delu na primeru uporabimo proces generativnega pristopa za načrtovanje elementov za senčenje, v zadnjem delu pa predstavimo rezultate obeh pristopovTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza društev gradbenih inženirjev in tehnikov Slovenije
