The potential of lichen and moss in sustainable contemporary
Transcript of The potential of lichen and moss in sustainable contemporary
What is a lichen?
Association of a photobiont and a mycobiont
"Lichens are fungi that have discovered agriculture"
Which parameters influence the bio-receptivity of a substrate?
What are the advantages of having lichens on a facade?
Influencing factors attributed to the
Influencing factors attributed to the
Distance from the sea
Presence or absence of vegetation
Composition of substratum
Wetness of facade (porosity, roughness)
Architectural parameters inducing micro-humidity
Cross section of a lichen
Same advantages of a Green facade with no need for apposite structure
Natural substitute for paint
Change colors in different seasons
Building Profile Beautification
Improved Air Quality
Biodiversity & Habitat
Biophilic Design and Inhabitant Health
Increased Thermal Insulation
Can be used as bio-monitor for air quality
Experiments to understand which material is better as substrate for lichen colonization
Lichens grow well in Iceland because it is one of the least polluted countries in the world. They draw their nutrients from the environment and are easily contaminated indeed.
Icelandic lava stone
Red lava stone
Icelandic lichen (Xantoria)
The moss wall at the Reykjavik City Hall (Studio Granda)
Collecting and casting the specimens to be used as substrates
Collecting the lichens both from Iceland and Denmark
"Gluing" the lichens to the substrates through a growth media
Observing if lichens attach to the substrate and if they grow.
From the outdoor experiment we will be able to define which substrate better fits for biocolonization by the specific type of lichen, and which exposition, orientation and type of structure is better for the lichen's growth.
From the indoor experiment we will be able to define how porosity influences the way lichens attach to surfaces.
