This paper discusses the results of a survey regarding state of the art and possible future opportunities for the application of robotic technologies in the construction industry. The survey was conducted by submitting two distinct questionnaires to Arup's1 most experienced technical and business leaders. The first questionnaire was designed in order to understand the state of the art of robotic technologies in the construction industry, while the second one aimed at identifying promising application scenarios from both the industry and the research point of view. The paper discusses how the questionnaires have been designed and presents the corresponding results.

This paper presents a generative grammar producing a language o f patterns for the south fa5ade o f a prototype sustainable house. The patterns are produced through the activation o f the electrochromic material that is applied on the windowpanes o f the facade. The class o f the performatively effective configurations o f the facade is approached as a visual language and the productive (generation), combinatorial (enumeration) and performative (verification) attributes o f this language are examined. Random, performance driven, patterns could supply sufficient interior daylight without acknowledging the visual potential o f facade pattern generation. The uniqueness o f the chosen approach is that the shape grammar encodes the performative constraints pertaining to the generation of facade patterns in a visual manner by associating principles o f two-dimensional pattern generation to levels o f illuminance.Light is an essential aesthetic and perform ative aspect o f architecture. The lighting o f interior spaces typically involves natural and artificial light sources. G iven that artificial lighting contributes considerably to energy consum ption, natural lighting is favored during daytime. This paper presents an exam ple o f how shape gram m ars, artificial intelligence (AI) m ethods for building control, and electrochrom ic technology can be com bined to regulate natural lighting in the interior o f residential buildings. The association between a specific architectural elem ent o f a prototype house-a fapade involving 100 electrochrom ic w indow s-and the adjustm ent o f the natural lighting conditions in the house interior is treated algorithmically. The facade operates as a dynam ic filter betw een interior and exterior perm itting the H Current address:
