Hlibivka is conceived as a self-sufficient complex that needs no electricity grid, gas supply, or water well or bore. There will be no earthworks.
The complex blends into the natural landscape. All structures touch the ground delicately and allow a continuous green blanket to form. To provide energy efficiency, the modules have super-insulated envelopes that comply with passive house standards.
Each living module is fully independent, so the complex can be built gradually, as financial capacity allows. The life-support engineering systems are located on the first level.
Almost every ecological and engineering function is expressed architecturally: water harvesting and water strategy, energy efficiency, energy generation, sun shading, ventilation, and interaction with the landscape.
Nine systems of one module
- 1Architectural means for energy efficiency. The overhang shields the panoramic south window from the high summer sun and lets the low winter sun in. Side panels block western and eastern rays. The canopy collects rainwater and solar energy and creates a ventilated double roof.
- 2Geometry for natural ventilation. About 3 m of vertical difference between air intake and outlet drives a passive draft: air enters on the cool north side and leaves on the warm south side.
- 3Life support system. The heart of the building, ensuring uninterrupted, independent operation without any external engineering networks.
- 4Rainwater harvesting and filtration. Half of the south canopy is retractable and changes position with the weather. About 110 m² of projection area feeds a 30-35 m³ tank sized for a daily demand of 350 litres; recirculation can cut that volume by up to 50%.
- 5Electricity production and storage. Wind generators of 10-15 kW in total, up to 18 m² of solar panels (3 kW) or hybrid panels, and 30-40 kWh of batteries.
- 6Heat generation and heating. Solar collectors or hybrid panels provide warm water, a 5-10 m³ heat accumulator stores excess heat, and an air-to-water heat pump of about 4 kW covers the main heating and hot water.
- 7Grey water recirculation. A recirculation unit purifies water from the shower and sink, covering about half of the daily demand and halving the rainwater tank.
- 8Black water treatment. Water with organic matter goes to a local treatment plant and is discharged to the environment in a safe state; a composter takes the solid fraction.
- 9Life support as an exhibition. With a constant rotation of visitors, the complex becomes a platform for demonstrating the life-support systems and the possibilities of sustainable solutions.
