Since the 1970s, bio-architecture has explored underground construction, focusing on reducing ecological footprints and enhancing microclimates.
These structures not only blend seamlessly into the landscape but also offer substantial energy savings and adapt well to complex topographies. Key benefits of subterranean buildings include stabilised internal temperatures due to the thermal inertia of the ground and superior thermal and acoustic insulation.

IGLU’® GREEN ROOF: The Sustainable Choice

To achieve efficient and sustainable underground buildings, the selection of appropriate materials and technologies is crucial. IGLU’® GREEN ROOF, a formwork system made from recycled plastic, exemplifies the fusion of ecological benefits and high technical performance, enabling the creation of green roofs with multiple advantages:

• Water Retention and Gradual Drainage: IGLU’® GREEN ROOF excels in retaining and storing water, promoting gradual drainage during heavy rainfall, which prevents vegetation loss due to either water scarcity or excess.
• Environmental Sustainability: This system enhances both the macro and microclimates, improving air quality and contributing to overall environmental health.
• Thermal Insulation: It contributes to the thermal insulation of the building, reducing heat loss in winter and offering natural cooling in summer, thus ensuring year-round indoor comfort.
• Acoustic Insulation: IGLU’® GREEN ROOF effectively mitigates sound transmission, reducing noise propagation to the rooms below and enhancing indoor comfort.
• Increased Property Value: The aesthetic and functional benefits of green roofs significantly enhance property value, making buildings more attractive and valuable.

Applications in Various Building Types

IGLU’® GREEN ROOF is ideal for a wide range of structures, including residential housing, commercial buildings, and public infrastructure. Its application in underground projects improves the sustainability of these buildings and enhances their appeal, creating more welcoming and pleasant environments for occupants.

The adoption of underground buildings offers an innovative response to modern environmental and urban challenges. With Daliform Group’s IGLU’® GREEN ROOF, projects can achieve a blend of sustainability, energy efficiency, and landscape integration.

By utilising modern technologies and thoughtful design, underground buildings can revolutionise construction and living spaces, contributing to a greener, more resilient future.
