Embodiments generally relate to a method for purifying air of an interior space by oxidizing a plurality of pollutant compounds suspended in the air. The method comprises exposing the air of the interior space to a photocatalytic layer, wherein the photocatalytic layer is disposed onto an at least one surface of a porous substrate material located in the interior space, wherein the photocatalytic layer comprises a plurality of photocatalyst particles, and activating the photocatalytic layer with a light source, wherein the activated photocatalytic particles promote a reaction between the pollutant compounds and the air.

Vehicles and methods for cooling a cabin using a cold roof of the vehicle are provided. The vehicle includes a roof, a cabin, and an insulation layer disposed between the roof and the cabin. The vehicle also includes a passage that fluidly couples the roof with the cabin. The passage is switchable between an open mode and a closed mode. The passage is switched between the open mode and the closed mode depending on a relationship between a roof temperature, a cabin temperature, and/or a threshold temperature. The passage may be formed through the insulation layer or extend outside of the insulation layer fluidly coupling the roof with the cabin.
