Digestible Gulf Stream

-Using this project [Digestible Gulf Stream] as a precedent for a current project and previously for Biophilia : Technophilia, Philippe Rahm portrays an architecture that is both unbounded by the partitioning of space and interwoven with the human physiological system. As the atmosphere surrounding the plates is conditioned within a thermal pocket, spatial structuring is no longer bounded by physical partitioning, but rather forms an open network interconnected with the space of the environment as it bleeds and merges into the physical surrounding. This projects shows how architecture and spatial organization may be constructed in a way that defies our modernist and industrial notions of cordoning space into polar oppositions. As we move further into the twenty-first century and beyond, as all space becomes public space, and our world becomes ever more integrated it may be so that our spatial constructions too follow suit–networking and fluidly merging. This project marks the first in a line of precedents as I move forward with my next project which will challenge such spatial conceptions through the merging natures of info, techno and bio.

Architecture as meteorology, architecture as gastronomy

The problem of global warming has placed as the relationship between climate and architecture at the center of current preoccupations. In order to assume our responsibility in the face of these new ecological concerns, we must make the most of the moment in order to reappraise the field of architecture in a broader way, extending it to other dimensions, other perceptions, from the physiological to the atmospheric, from the sensorial to the meteorological, from the gastronomic to the climatic. A ‘Digestible Gulf Stream’ is the prototype for architecture that works between the neurologic and the atmospheric, developing like a landscape that is simultaneously gastronomic and thermal.

Architecture as Meteorology
Architecture should no longer builds spaces, but rather create temperatures and atmospheres. Here, two horizontal metal planes are extended at different heights. The lower plane is heated to 28°C, the upper one is cooled to 12°C. Like a miniature Gulf Stream, their position creates a movement of air using the natural phenomenon of convection, in which rising hot air cools on contact with the upper cool sheet and, falling, is then reheated on contact with the hot sheet, thus creating a constant thermal flow, akin to an invisible landscape. What interests us here is not the creation of homogeneous, established spaces, but of a plastic, climatic dynamic, the activation of forces and polarities that generate a landscape of heat. In this case the architecture is literally structured on a current of air, opening up a fluid, airy, atmospheric space. This architecture is based on the construction of meteorology. The inhabitant may move around in this invisible landscape between 12°C and 28°C, temperatures at the two extremities of the concept of comfort, and freely choose a climate according to his or her activity, clothing, dietary, sporting or social wishes.

The concept of thermal comfort depends not only on external temperature, but also on clothing, the physical activity of those who live in the space and their diet. For example, when we feel too hot, we have five ways of cooling down, which act on different scales:

1. reducing the air temperature in the room, for example by air conditioning (atmospheric solution);
2. drinking (physiological solution);
3. taking off clothes (social solution);
4. resting (physical solution);
5. stimulating a sense of coolness with the mind (neurological solution).

Each one of these solutions is architecture. Architecture is a thermodynamic mediation between the macroscopic and the microscopic, between the body and space, between the visible and the invisible, between meteorological and physiological functions.

Architecture as Gastronomy
We then propose to add two culinary/pharmaceutical preparations to the two plates that directly stimulate the sensory receptors of hot and cold at the cerebral level and that can be eaten or applied to the body.The first preparation, on the upper cold plate, contains mint, which has molecules of crystalline origin known as menthol that cause the same sensation in the brain as the coolness perceptible at a temperature of 15°C. The menthol activates the TRPM8 (transient receptor potential) molecular sensory receptors on the skin and in the mouth that stimulate the group of peripheral sensorial neurons known as cold-sensitive units. The second composition, on the lower hot plate, contains chilli, in which one of the molecules, capsaicin, activates the neuro-receptor TRPV1, which is sensitive to temperatures over 44°C.

The traditional field of architecture thus expands, operating on both the atmospheric and gastronomic scales, breaking down the barriers between internal and external, body and space, neurology and physiology. The sensations of hot and cold may be perceived as much inside the body (diet) as outside (atmosphere). So the question of diet also comes into the field of architecture, on a par with its climatic dimension.

Our architecture extends between the microscopic and the macroscopic, the gastronomic and the atmospheric, the visible and the invisible. Architecture becomes a ‘Gulf Stream’ that polarises the contrasts on different scales (hot/cold, low/high, clothed/unclothed, internal/external, rest/activity) to give rise to architecture as a convective movement of air, creating a place like geography, designing space like climate, atmosphere and gastronomy.
