A system and method for computing design parameters for a thermally comfortable environment is disclosed. In one embodiment, a surface heat transfer coefficient (hea1) is obtained for each body part of one or more thermal manikins in a uniform thermal environment by performing a 1 D numerical analysis on the uniform thermal environment based on a given set of boundary conditions for the uniform thermal environment. Further, equivalent temperature (teq) limits for each body part corresponding to the thermal comfort limits are obtained from known design standards.
