Abstract

In New Zealand’s (NZ) mild climatic conditions, mostresidential houses are ventilated naturally, mainly by opening windows. However, maintaining the indoor thermal comfort characteristics ofa house by modulating natural ventilation is particularly challenging,as the solution is not explicit. Determining a solution requires atechnique that adjusts openable window area while encapsulating thecomplexity, dynamics, and nonlinearity associated with the naturalventilation driving forces and building thermal behavior. By verifyingthat there exists a significant potential of regulating indoor thermalcomfort of a relatively airtight and insulated house by adjustingwindow openable area; this work additionally confirmed an excellentcapability of Artificial Neural Network (ANN) technique in predictingair temperature time-series of the naturally ventilated house. Onthe basis of these examinations, this work particularly developed aco-simulation strategy between building thermal-airflow model andthe ANN model and demonstrated that windows could be regulatedintelligently to modulate the natural ventilation and maintain indoorthermal comfort level during the summer period by applying ArtificialNeural Network (ANN) based predictive controller technique.

OtherThe territories of computational design are ever-changing and represent a substantial region that remains uncharted; one with expanding and permeable boundaries that continue to be fully breached. This ocean of opportunity implores researchers to embark on ambitious journeys of exploration. Undulating and temporal, computational design needs research that engages explicitly with the innovative, intelligent and informed exploitation of computational design, and with the array of computational technologies that the discipline may engage with. Human intelligence and creativity deliver the hegemonic direction for the field of computer-mediated architectural design research; an area where the computational component is a core aspect of the investigation. The actors in this are both witness to, and instigators of, the exciting, consequent, well-founded research that continues to deliver new knowledge, insights and information. This, then, explains the specific overarching theme of the conference: ‘Intelligent & Informed’.
