We are more obsessed with visual impact and less with needs and functions. Our design manifestations are nothing but a celebration of technology.The spaces we create have no soul. We try to justify them after they have been created. This paper calls for a paradigm shift in the way we approach our design interventions. Our spaces should be created based on the activities we are supposed to perform in them. Our activities should be based on circadian rhythms and chronobiology. Tangibly and intangibly our main source of energy is the sun. Our entire biological clock is synergetic with the earth’s orbit and the position of the earth relative to the sun. A correlation matrix is sought to be established between the position of the earth, human circadian rhythms, chronobiology, proposed activities and climate. It is argued that if our architectural expressions are evolved based on scientific processes they would be more relevant and meaningful. The various ways in which this can be achieved is briefly discussed and presented. The advantages of this approach are briefly enumerated. It is also ensured that all the proposed solutions are sustainable, co friendly and have the least impact on the environment.

INTRODUCTION Architecture is based on the principle that Anthropos or Humans are the centre of concern and all design concepts and manifestations should be focused towards this goal. Ergonomics, Anthropometrics and Ekistics were some of the sciences developed with this objective. These sciences have done their bit and continue to address the physical comforts of humans. Physical comforts are the tangible aspects. The critical fact which seems to have been missed out is that humans are not creatures of logic-they are creatures of emotion. Unless they are emotionally happy they can never appreciate physical comforts. Our design interventions should focus on these intangible aspects for the solutions to be accepted, appreciated and implemented. To implement this we need to understand the basic fundamentals of circadian rhythms and chronobiology. Importance of circadian rhythms The importance of this study can be illustrated by the fact that the Nobel Prize in Physiology for the year 2017 was jointly awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their discoveries of molecular mechanisms controlling the circadian rhythm. Refer to the following image no-1 for the press notification.

This science was conceived by a renowned French astronomer Jean Jacques d’Ortous de Mairan in the eighteenth century. RESEARCH ARTICLE OPEN ACCESS
