Geo-engineering explorations are not limited to planet earth alone. As computational science advances, design architects have joined mechanical engineers to find technological solutions reaching the loftiest frontiers of space exploration. India is poised to play a very substantive role in the years to come. The primary objective of this article is to illustrate the integration of sustainable architectural designing and computational thermal analysis of the habitation module for Mars. It involves a first-time off-line simulation of Planetary Weather Research and Forecasting to yield the solar insolation, temperature and pressure plots to determine the ideal site for habitation. The rectangular building form is chosen for the ease of transportation and exploration, with carefully positioned skylights and vents to enhance the sustainability. Most importantly, many sensitivity tests were performed on the building fabric to obtain the optimal U value (thermal transmissivity) by varying the thickness of the man-made fabrics. Ecotect simulations have been used to show the most plausible orientations that will modulate solar insolation patterns. The Computational Fluid Dynamical (CFD) simulations help us concretize the form and fabric that regulate the cool and warmth within the inhabited shell housing four human being. This unique combination of planetary meteorology and eco-architecture is exciting and achievable by India's young engineering talent pool. © 2015 Taylor & Francis.
