Based on the investigation on the residential buildings in Vietnam, we created a typical tube house model for Vietnam. Effects of various passive methods, such as thermal insulation on the interior side of walls, exterior blinds, heat reflective glass, double roofs with air layers, etc. on the model house are examined with simulations. An energy saving house model is proposed combining all the effective passive methods mentioned above. It is clarified that cooling load can be reduced by the energy saving model by 47% and 35% when only the main bedroom or the whole house is air-conditioned, respectively. Based on the analyses, proposals are made for the design of tube houses in Vietnam.
