Green Facade

The green facade forms a central part of Biohavn’s initial concept and explores how building envelopes and selected interior structures can move beyond passive architectural functions and actively contribute to environmental performance.

Within this approach, microalgae are integrated into transparent facade panels or architectural elements. The microalgae grow through photosynthesis using either natural sunlight on exterior facades or artificial light, such as LED systems, in interior applications. Through this process, the facade can contribute to carbon dioxide absorption and moderation of environmental conditions both outside and inside buildings.

The feasibility of algae-based facades has already been demonstrated in practice. A notable reference is the BIQ House in Hamburg, Germany, where microalgae panels were implemented at full building scale.

As embodied carbon and carbon-related taxation in the construction sector continue to gain importance, green facades offer not only environmental value but also a potential economic benefit by helping buildings reduce long-term carbon-related costs and remain compliant with evolving regulations.

Biohavn’s work on green facades focuses on gradual development and alignment with architectural practice, technical requirements, and regulatory frameworks in Denmark and the European Union.
