Liao Liao One Cup is a single-story cafe pavilion built next to the Luoyang Museum in Luoyang, China. The building applies passive house principles to reduce the need for mechanical cooling. An undulating roofline, inspired by the ancient Luo River, draws air through the open-plan interior and forms the main architectural feature. Weathered Corten steel and mirror-polished stainless steel clad the exposed steel frame, removing the need for added finishes. A raw stone ceiling provides thermal mass, and floor-to-ceiling glazing brings in daylight.
Press Kit
- Unique Properties
- This cafe pioneers passive house application in commercial hospitality, using the undulating roofline as both environmental system and cultural landmark. Natural ventilation replaces mechanical cooling while Corten steel and mirror-polished stainless steel create a bold material vocabulary. Adjacent to a major museum, the design establishes a new architectural identity for sustainable public gathering spaces in heritage contexts, proving innovation and cultural resonance can coexist.
- Dimensions & Packaging
- Single-story cafe pavilion featuring passive ventilation roofline, weathered Corten steel and mirror-polished stainless steel cladding, exposed steel structural framework, raw stone thermal mass ceiling, and floor-to-ceiling low-E glazing. Climate-responsive roof geometry optimized for natural airflow and daylight penetration. Minimal mechanical cooling systems required.

- Production Technology
- The undulating roofline integrates passive house engineering with sculptural fabrication. Corten steel panels and mirror-polished stainless steel were precision-formed to optimize natural airflow patterns derived from computational climate analysis. Exposed structural frameworks eliminate the need for secondary finishes, reducing material waste. Raw stone ceiling textures provide thermal mass for passive temperature regulation. The entire construction strategy prioritizes long-term environmental performance alongside minimal site intervention.
- Design Challenge
- The core challenge was threefold: achieving passive house performance through architectural form alone, creating a recognizable cultural landmark adjacent to a major heritage institution, and proving these goals are complementary rather than contradictory. The resolution embedded environmental function within the sculptural roofline, allowing a single design element to serve as climate system, cultural symbol, and brand identity simultaneously.
- Project Duration
- Completed adjacent to Luoyang Museum, Luoyang, Henan Province, China in 2025
- Operation Flow
- The passive ventilation system shapes the visitor experience from arrival. The roofline draws air naturally through the open-plan interior, creating thermal comfort without mechanical noise. Floor-to-ceiling glazing connects visitors to the museum landscape while maximizing daylight, reducing energy consumption. Material transitions from raw Corten to polished steel guide movement through zones of varying intimacy, each defined by sustainable material honesty rather than decorative excess.
- Research
- This project advances passive house application beyond residential typology into public commercial architecture. The roofline functions simultaneously as cultural landmark and environmental system, demonstrating that climate-responsive innovation can generate architectural identity rather than constrain it. Situated in a heritage district, the design proposes a replicable model for sustainable cultural landmarks that honor context through contrast rather than imitation.
- Inspiration
- Situated beside the Luoyang Museum, this project was inspired by the challenge of creating a new cultural landmark that advances sustainable building practice. The sculptural roofline channels the ancient Luo River, embedding climate-responsive innovation within cultural symbolism. The vision was to prove that passive house principles can define the next generation of public architecture in heritage districts, where environmental innovation and cultural identity reinforce each other.
