Green walls & living facades

Vertical greening systems — from climbing plants on a facade to modular living walls — that replace conventional cladding with a vegetated building envelope; commercial and still a small share of the facade market.

1 · What it gives

Vertical greening systems (VGS) support vegetation growing on a building facade or wall, from simple climbers to modular living walls with engineered substrates. They act as an alternative to conventional cladding in stone, concrete or fibre cement, turning a flat finish into an active, vegetated envelope. The technology is a mix of pilot and commercial: monitored pilots such as an 850 m² wall installed in 2010, and field tests of bioreceptive concrete panels running since 2021. VGS is estimated at 1–2 % of the global facade market.

3 · How to implement 5 steps

1
Feasibility and design
Assess the site and climate context and the feasibility of the system.
2
Typology and species
Choose the system type (facade-climbing or living wall) and the plant species.
3
Frame and irrigation
Install the supporting structure and the irrigation system.
4
Planting and substrate
Set up the substrate and install the plants.
5
Operation
Establish a maintenance, monitoring and irrigation protocol.

5 · Rules & route to market

Route into Russia / EAEU: NOVEL · Rospotrebnadzor / EAEU
state registration as a new type of food; no fixed term published
Information, not legal advice — confirm the procedure for your product. (2026-10-06)

United States

The sources reviewed on 2026-10-16 identified no the US regulator or standard specific to this technology. Treat the route as case-by-case and ask for a check.

European Union

Rules sit in standards and municipal planning tools rather than one regulator: Austria’s ÖNORM L1136, Italy’s Law of 14 January 2013 No. 10, and area-based planning tools such as the Biotope Area Factor and the Seattle Green Factor.

China

The sources reviewed on 2026-10-16 identified no China regulator or standard specific to this technology. Treat the route as case-by-case and ask for a check.
