This is a heating and cooling system, and method that utilizes the roof of a home or building as a solar collector. A heat barrier material is secured to the inside free edges of the roof rafters to reflect radiant heat into air flow passage ways formed between the rafters, the attic side of the roof and the heat barrier materials. A loft or upper attic floor is built in the upper portion of the attic and is also covered with the heat barrier material. The attic is divided into separate areas that are connected by a ducting system that includes a filter, an evaporator and a blower. The blower produces airflow through the filter and over the evaporator coil and into a separated portion of the attic. Airflow moves through selected formed channels between rafters, barrier material and inside roof to the blower for re-circulation. This closed loop system is usable with conventional air-to-air heat pump systems, with portions of such systems or with other well-known devices such as heat exchangers and heat engines.

The method according to claim 5, wherein the adjusting speed is <2.5 mm/min. 7. The method according to claim 5, wherein, for a constant casting speed and with the solidification point of the billet having passed the first and second segments, the exit side of the first segment and the entry side of the second segment in the casting direction are advanced in a first one of the adjusting steps toward the billet by moving the first and second segments at a joint connecting the first and second segments toward the billet controlled in accordance with a set-point, and after the first and second segments have reached a target position, an exit side of the second segment and an entry side of the third segment in the casting direction are advanced in a second one of the adjusting steps toward the billet by moving the second and third segments at a joint connecting the second and third segments toward the billet, and after the second and third segments have reached a target position, the third and further segments are advanced toward the billet sequentially in the same manner in further ones of the adjusting steps until all segments have reached a target position. 8. The method according to claim 7, wherein the segments are adjusted at a constant adjusting speed with dynamic position control without surpassing a predetermined force threshold value, the method further comprising the step of determining an adjusting speed of the segments for advancing the segments based on permissible billet elongation limits and a current casting speed in combination with a current format adjustment of the section or based on a required volume flow of the billet. 9. The method according to claim 8, wherein the adjusting speed is calculated, based on the current casting speed, the segment length, and the format thickness change, by the equation V=Ds/Ls*Vcast wherein Ds is the format thickness change, Ls is the segment length, and Vcast is the current casting speed. 10. The method according to claim 9, wherein the adjusting steps are carried out by hydraulic adjusting devices, further comprising the step of monitoring the adjusting steps via current cylinder pressures of the hydraulic adjusting devices, wherein, when a predetermined force threshold value is surpassed, force control is applied instead of position control and wherein, when the target position has beer reached, the position control is applied again. 11. The method according to claim 10, wherein the adjusting steps are hydraulically controlled and wherein the adjusting steps begin at an exit side of the first segment in the casting direction and are successively continued at the entry side and the exit side of the successively arranged segments, and wherein the adjusting speed of two successively arranged segments is inevitably synchronous. 12. The method according to claim 4, wherein, when the billet guide has at least four segments, the billet profile for increasing the section is formed by the steps of: at a selected length zero of the billet, moving an exit side of a first of the segments and an entry side of a second of the segments away from the billet; subsequently, time-delayed or travel-delayed by a length of the second segment, moving an exit side of the second segment and an entry side of a third of the segments away from the billet; subsequently, travel-delayed by a length of the third segment, moving an exit side of the third segment and an entry side of a fourth of the segments away from the billet; and subsequently, travel-delayed by a length of the fourth segment, moving an exit side of the fourth segment away from the billet, wherein all segments are moved away from the billet until a preset final thickness is adjusted. 13.
