Abstract	The solution of accumulating and keeping the heat in the walls is through insulating from the outside, a common method used in Europe although it hadn't been confirmed on the physical basis, in regards with the conditions of continental climate, may it be in winter or in summer. In effect, during summer season part of the heat gets inside despite the insulations in the walls and over the night the condition within doesn't improve as the insulation would not let it pass through. During winter season, it is unacceptable to sacrifice solar energy when there is still plenty of a sunny day, for the reason that the insulation on the external side of the walls is blocking the sun's energy. From aspects of thermodynamics, the best solution would be to set the insulation on the ceiling and to use walls with optimal thermal insulation thru their entire thickness and at the same time, which are sound- and fireproof as well. This article recommends technical solutions, confirmed by positive feedbacks; StiroFert and a lightweight formwork-insulating concrete blocks, demonstrate and execute a high energy efficiency (energy consumption for heating and cooling of 64 $KW/m^{2}$ on an annual basis). In order that heating and cooling system through the use of heat pumps with downhole heat exchangers and with the coefficient of thermal efficiency of 1∶5 to 1∶6, it is necessary to implement this solution of transferring the solar energy into the ground around the downhole heat exchangers, so it could be applied not only individually but also in major cities. This technology would not only return the seized energy from the ground but could also bring in the ground a much larger amount of totally free solar energy by transporting through the thermal oil from solar collectors to the ground around the downhole heat exchangers. The leading consumers of energy in the world are buildings. In average, they use 50% of the total produced energy. The consumption would be reduced enormously in up to 15% using the described solution. Thus, the result would be the end of all crises that have befallen the world (energy, ecological, economic), improvement of world economy, social development and prosperity of mankind.
