Sunmay

Sunmay is a term used in speculative design and future-energy studies to describe a holistic approach to integrating daylight, solar energy capture, and building performance within urban systems. The concept envisions buildings and districts that maximize natural light and passive solar heating while coordinating on-site solar generation, storage, and smart control to align energy supply with demand and occupant comfort. The name combines sun with May, signaling a seasonal emphasis on daylight-rich periods in temperate climates, though the concept is intended to be adaptable across locales.

Origin and usage: Sunmay emerged in design fiction and thought experiments in the early 2020s, appearing in scholarly essays and public demonstrations exploring low-carbon urban futures. It is not a single standardized blueprint but a family of scenarios that share the aim of tightly coupling daylight and solar resources.

Principles: Core ideas include orientation and fenestration strategies that optimize daylighting; dynamic shading and responsive façades to modulate heat gains; integration of photovoltaic and solar-thermal systems with modular storage; and digital control layers that forecast weather and occupancy to minimize energy use while maintaining comfort.

Applications: In theory, sunmay informs architectural design, district-level planning, and microgrid development, guiding decisions on envelope design, glazing ratios, shading devices, and energy storage sizing.

Reception: Critics note that sunmay is a conceptual framework rather than a turnkey technology; its real-world realization depends on advances in materials, data analytics, and governance structures for shared energy resources.
