GASPER – Climate-Responsive Architecture for Tropical Regions

Gasper is an experimental architectural proposal conceived for tropical climates, where high humidity, intense solar radiation, and fluctuating wind patterns demand innovative environmental strategies. Developed as a children‑oriented facility, the project translates climatic forces into architectural form, creating a building that behaves like a living organism—breathing, adapting, and responding continuously to its surroundings.

The project was designed by Yeganeh Esmaeilkhani, Afshin Razmi, Elnaz Samandari, and Ali Khani, and was awarded the People’s Choice Award in the Form Follows Climate 2020 competition.

At its core, Gasper embodies the principles of climate‑responsive architecture, where form, envelope, structure, and spatial organization work together to minimize energy consumption while maximizing comfort, daylight, and natural ventilation.

Building Envelope as a Living Skin

The architectural concept begins with the building envelope, treated as a responsive skin rather than a static boundary. Inspired by marine sponges and porous natural systems, the envelope integrates walls, roofs, floors, and fenestration into a unified climatic interface.

Like human skin, the envelope reacts to environmental stimuli. Its porous surfaces allow air to flow freely, enabling cross‑ventilation and stack effect cooling, while selectively filtering daylight to reduce glare and overheating. The envelope is directly integrated with the structural shell and mechanical systems, allowing individual façade components to open or close in response to extreme weather conditions.

This responsive envelope becomes a key driver in the project’s identity as a sustainable and adaptive architectural organism.

Site Strategy and Modular Logic

The site planning follows a clear modular system based on 30×30 spatial units, scaled to the step length and movement patterns of children. These modules are arranged along prevailing wind axes to enhance natural ventilation and ensure effective airflow across all spaces.

Strategically placed voids between modules amplify daylight penetration and strengthen the building’s natural ventilation performance. Transparency at ground and intermediate levels creates visual continuity between interior and exterior spaces, reinforcing a sense of openness and safety.

Green terraces, pilot areas, and photovoltaic ring structures are layered into the overall massing, transforming the site into a multi‑climatic landscape rather than a single enclosed building.

Passive Design Strategies

Gasper integrates a wide range of passive design strategies that define its climate‑responsive architectural approach:

• Incorporative shading elements that reduce direct solar gain
• Self‑shading façade openings that regulate sunlight throughout the day
• Cross and stack ventilation supported by sub‑floor airflow systems
• Rainwater harvesting systems for collection and reuse
• Photovoltaic panel rings generating renewable energy
• Solatube daylighting systems delivering natural light deep into interior spaces

Together, these strategies significantly reduce dependency on mechanical cooling while ensuring thermal comfort in tropical conditions.

Interior Experience and Spatial Planning

Internally, Gasper is designed as a fluid and playful environment that encourages movement, exploration, and social interaction. Curved walls, soft materials, and organic geometries create a child‑friendly atmosphere while maintaining spatial clarity and safety.

A central courtyard anchored by palm trees functions as a climatic heart, drawing air through the building and creating shaded communal spaces. Interior zones are organized to support educational, recreational, and restorative functions, including classrooms, workshops, amphitheaters, and quiet treatment areas.

The layout conceptually reflects the footprints of a mother and child placed side by side, symbolizing protection, care, and emotional bonding. This metaphor translates into zoning logic, where service areas are absorbed into the building’s larger boundary, leaving primary spaces uninterrupted and flexible.

Functional Zoning and Circulation

The building is distributed across multiple levels with clear functional separation:

• Ground Floor: Amphitheater, supporting areas, and primary circulation
• First Floor: Kids’ activity zones, classrooms, and shared learning spaces
• Second Floor: Green terraces, educational zones, and vertical connections

Vertical circulation elements double as ventilation shafts and daylight channels, reinforcing the building’s environmental performance while enhancing spatial orientation.

Energy Performance and Sustainability

Energy analysis demonstrates the effectiveness of the project’s climate‑responsive strategies. Cooling demand is significantly reduced through passive airflow systems, while daylight‑optimized interiors lower artificial lighting requirements. Electricity consumption is partially offset by photovoltaic systems, and water efficiency is enhanced through rainwater harvesting and reuse.

The building operates as a low‑energy system where architecture itself becomes the primary environmental regulator.

A Living Architecture for the Tropics

Gasper stands as a compelling example of climate‑responsive architecture in tropical regions—one that merges biomimicry, sustainability, and social sensitivity. By treating architecture as a living organism rather than a static object, the project demonstrates how design can simultaneously nurture human well‑being and respond intelligently to environmental challenges.

Through its porous envelope, modular planning, and passive strategies, Gasper offers a visionary model for future educational and community spaces in climate‑vulnerable regions, where architecture must not only shelter life but actively support it.
