Through the reformulation of a predesigned Velux element (solar tube) and the investigation of the photosynthesis process, we have designed a new anatomical concept of housing based on the gaseous secretions of plants, capable of absorbing carbon dioxide to convert it into oxygen and in passing low temperatures that act as natural refrigerants of the environment. These plants, located on a lower level of the house to allow cold air flow up through the levels, are supplied with daylight through the rethought solar tube to reach dimensions that allow its insertion throughout the entire house. up to the level where the plants are located. Thus, this tube acts as a feeder for these and, by means of openings inside the tube directed towards the spaces that surround it, the cold air that rises through the tube circulates without losing its property and original concept: lighting hidden spaces inside the home . All this design is finished off with the anatomical reinvention, inverting the classic roof slopes inwards to repeat the solar rays inside the tube and act, in a third instance, as a water collector for the same plants with low care and high absorption of dangerous gases like formaldehyde, being useful both in summer and winter in different areas.
