Building materials were a major influence on the condition of the air inside the building covering the walls and roof of the building materials. This was caused by an area of the walls and roof that dominates the surface area of the building. Buildings that save energy by sustainable building is a building that is much use of local building materials. One wall of the building materials which are of local building materials and do not use a lot of energy in the manufacturing process is compressed earth block (CEB). Energy for heating and cooling of buildings are depending on the location where the building is located. This study aims to determine the appropriate building walls for warm and cold climate areas. Simulations carried out by using a model of the building with a size of 3 x 3 x 3m. Heat energy and embodied energy of building materials in the building model is calculated using the program. Variables research are CEB wall thickness and fiber concrete panels. Optimization was done to determine the model of the building that has heat energy and embodied energy balance. Results of the study are as follows a model that is suitable for hot climates are model-walled half-brick and concrete fibre panels coated on both sides. Model suitable for cold climates is a model that has a brick wall and covered by fibre concrete on the outside.
