 A high energy efficiency class for residential buildings can be achieved if the insulation principles are more stringently considered. Also, it is necessary to analyze and define where the heat losses occur realistically. However, there is a question whether the calculation of energy gains (solar, from electrical devices, and people) that is recommended in some Rulebooks on the energy efficiency of buildings is sufficiently accurate and reliable. It is known that energy gains can only increase the guarantee of achieving the projected energy class of the observed facility, and therefore, it should be careful in their calculation. In this paper, it is presented with constructive solutions of the walls and floor plates that are made with less volume of ordinary concrete and bricks in order to reduce the ability of thermal energy accumulation. All foundations must be completely thermally insulated with lightweight concrete, and balconies have to be fully concreted with lightweight concrete as well as gable walls. Energy-efficient design and construction solutions for lightweight cassette floorboards and facilitated walls are proposed. There is warm air beneath the ceiling of the rooms, so thermal insulation must be placed on the ceilings of the floorboards of each floor. It is a solution and a condition to prevent thermal energy input into the floor concrete slab and to transfer it to the walls. In this case, the warmer air below the ceiling would naturally move around the room to the floors in the physical tendency of heat transfer and thermal heat equilibrium. This would help prevent heat loss and a general sense of heat for occupants on the floor of the room. The walls at the corners of the buildings should be semi-circular because in this way we prevent the occurrence of significant linear losses of thermal energy. Another reason for such corner solutions is increased safety in case of seismic actions. The aesthetic appearance of such buildings is superb and worthy of the attention and admiration of both building occupants and passers-by.
