Building for the Next Millennium: The HHF Cement-Less Mosque

This is outlines a revolutionary, fully sustainable architectural blueprint designed to withstand the harshest desert climates. By combining ancient passive physics with cutting-edge materials science, this project redefines how we build places of worship in arid coastal regions.

Traditional construction relies heavily on Ordinary Portland Cement (OPC), a major contributor to global carbon emissions. In extreme desert environments, standard buildings fight nature with high-energy air conditioning and rely on vanishing or trucked-in water supplies.

The HHF Cement-Less Mosque is a 2,000 m² two-story sanctuary that works with the desert. Built completely without cement, it generates its own freshwater from the sea and uses the constant temperature of the earth to keep its indoor climate perpetually cool.

1. Structural Mastery: Building Without Cement

To eliminate cement entirely, the mosque utilizes advanced Geopolymer Concrete for every structural element—from the underground footings to the towering central dome.

• The Material Composition: The structure replaces cement with industrial byproducts like fly ash and slag, chemically activated using a liquid sodium silicate binder.

• The Dome & Walls: The self-supporting half-sphere dome and the 2-story frame are cast with this geopolymer mix, producing a white finish that reflects harsh solar radiation.

2. The Integrated Cooling Matrix: Defeating the Desert Heat

Instead of consuming massive amounts of electricity via traditional HVAC units, the mosque relies on a continuous, closed-loop shallow geothermal and thermodynamic airflow design.

Ground Source Synergy

• Shallow Geothermal System (SGS): A network of subterranean piping loops runs deep beneath the mosque's foundation, tapping into the earth's stable, cooler underground temperature.

• Water-to-Water Heat Pumps: High-efficiency heat pumps extract warmth from the building and dump it into the ground loop, chilling a central thermal storage water tank.

Passive Aerodynamics

• Raised Access Flooring: Chilled air is quietly distributed through an underfloor plenum directly into the main prayer hall, cooling the zone where congregants gather.

• The Venturi Air Duct & Dome Cowl: As solar heat warms the outside of the geopolymer dome, it creates a natural thermal siphon. Low pressure created at the top Venturi cowl pulls warm air up and out of the building naturally, drawing fresh, geothermally cooled air up through the floors without the need for loud, high-energy fans.

3. Infinite Fresh Water: Sea Water Desalination

Positioned on a desert seashore, the mosque avoids straining local municipal grids or groundwater tables by hosting its own modular, stainless-steel Seawater Desalination Facility.

This combined system ensures a reliable supply of fresh water for ablution (Wudu), drinking fountains, and local landscaping, while completely eliminating chemical waste streams. This design develop at www.biocom.id.
