holesin

Holesin is a fictional design concept used to illustrate how deliberate voids can influence the performance and aesthetics of built environments. The term combines "holes" with the preposition "in" to denote voids embedded within a surface or structure. In this concept, holes are not defects but intentional features engineered to achieve multiple functions.

The core idea of holesin is to control the size, shape, spacing, and connectivity of holes within a material or facade. Perforations may be regular or irregular and can vary with depth, creating a three-dimensional network that interacts with light, air, and sound.

Design goals of holesin include improving natural ventilation, enabling daylighting, reducing weight, and creating distinctive visual textures. The perforated patterns can also influence thermal performance by shading or cooling surfaces, depending on climate.

Applications span architecture, product design, and urban furniture. Examples include perforated building facades for passive cooling, lattice panels in interior partitions to modulate sound, and 3D-printed components with internal void networks to reduce material use.

Challenges involve balancing structural integrity, weather resistance, and maintenance with the desired level of porosity. Computational tools such as parametric design and finite element analysis are commonly used to optimize holesin patterns.

Holesin remains a theoretical construct used in design discourse and is not widely adopted as a formal standard. See also perforated architecture, porosity, lattice structures.
