Experimental Pavilion

The Experimental Pavilion is the result of a research process centered on a single question: what does architecture look like when climate performance is treated not as a constraint to be managed but as the primary design generator?

The conventional approach to high-performance building envelopes prioritizes certified systems Passivhaus-compliant panels, triple-glazed curtain walls, prefabricated composite solutions that achieve their targets at considerable cost. Our research began from the opposite premise: accept severe cost constraints and find solutions that exceed performance benchmarks despite them.

The breakthrough was the envelope itself: standard industrial tubes, packed with high-density insulating material. This system, assembled in a continuous surface across the building's curved profile, achieves a thermal transmittance of 0.1 W/m²K significantly better than the Passivhaus standard of 0.15 W/m²K  at a construction cost lower than conventional alternatives.

The curved geometry of the building is not an aesthetic decision. The curved profile minimizes the surface-to-volume ratio of the enclosed space, which directly reduces heat loss per unit of interior volume. In thermodynamic terms, the curved form is more efficient than a rectilinear one. The form follows from the physics.

This inversion form as the result of research rather than form as a starting point — is what makes the project architecturally honest. Its beauty, such as it is, arises from logic rather than from imposed composition.
