Disclosed are methods and functional elements for enhanced thermal management of predominantly enclosed spaces. In particular, the invention enables the construction of buildings with reduced power requirements for heating and/or air-conditioning systems since under certain conditions less energy for heating or cooling is required to maintain, within certain boundaries, desirable temperatures inside such buildings, habitats, or other enclosed spaces.

In some instances the invention is in part based on dynamically changing functional elements with variable properties, or effective properties, in terms of their electromagnetic radiative behavior and/or their thermal energy storage properties, or the spatial distribution of the stored thermal energy, which permits the application of methods and algorithms to control the overall thermal behavior of the entire structure in such a way that desired levels of inside temperature can be reached with reduced consumption of external energy (typically electricity, gas, oil, or coal).

In some instances no conventional heating of cooling is required at all, whereas in other instances the expenditure of external energy for conventional heating or cooling is reduced. In some instances the invention enables the reduction of the time to reach desired temperatures inside such buildings, habitats, or other predominantly enclosed spaces.

A concentrated solar thermal receiver is mounted on a tower to receive concentrated solar thermal energy from a concentrating array of solar reflectors. The receiver comprises a single layered array of tubes configured to carry a heat transfer fluid such as sodium and defining in combination an exposed concentrated solar thermal energy receiving surface. The array of tubes have a lower fluid inlet header communicating with an inlet conduit, and an upper fluid outlet communicating with an outlet conduit. The tubes are arranged in a serpentine configuration and define a fluid flow path which is predominantly transverse and upward. The receiver includes a thermally insulating cover movable between an open position and a closed position in which the solar thermal energy receiving surface is covered to block or reduce the incidence of solar flux on the tubes or to reduce heat loss from the array of tubes when they are not operational.
