Zero-Emission, Eco-Friendly, Passive, Low-Energy Wooden Kindergarten in Selnica ob Dravi

The kindergarten, completed in 2024 by GIC Gradnje, LUMAR, and Studio Baza, provides space for 200 children within its 3,000 m² area. Constructed using Slovenian wood—harvested, processed, and manufactured entirely in Slovenia—the build minimises transportation emissions and ensures a low carbon footprint. The natural properties of wood allow the building to have negative CO₂ emissions, with wood storing carbon dioxide throughout its life. The structure utilises 510.2 m³ of Slovenian spruce wood.

An innovative dowel-joining method, which employs wooden screws instead of traditional adhesives, was employed. This method, recognised with the German Innovation Award in 2024, is free from chemicals, enhancing indoor air quality. For the flooring, wooden fibres and special linoleum were used, which aid in natural moisture regulation, fostering a healthy environment. Heating and cooling are managed by a heat pump that already draws 58% of its energy from renewable sources.

A solar power plant with a capacity of 43 kW was installed on the roof in 2025, catering for approximately 50% of the building’s electricity needs and taking the share of renewable energy sources above 80%. The energy systems are integrated into a sophisticated remote control system, enabling real-time energy optimisation. Sensors monitor temperature, humidity, CO₂, and particulate matter to adjust ventilation according to actual indoor conditions, ensuring optimal air quality.
