A method and apparatus for controlling the temperature of (e.g. cooling and/or shading) an area is described. A hollow, translucent or transparent panel 10 is mounted adjacent the area and fluid is passed through it a rate proportional to the degree of temperature control required. The fluid may be heated and/or cooled; it may be transparent, translucent or opaque; it may be coloured. The panel may be flat or curved and has in it a plurality of fluid tight passageways (generally linear or sinuous) coupled to fluid supply means 26 energisable responsive to the temperature on one side of the panel. Enclosures (figures 4 and 5) are described formed of a number of similar panels mounted in a framework, which enclosures comprise permanent or temporary buildings or other structures, or temporary extensions for buildings or vehicles. The framework may be used to pass the fluid to/from the panels.
