# Choosing a green facade: systems, costs and maintenance for commercial buildings

## What is a green facade?

A green facade is an exterior wall with living vegetation. It can use climbing plants on a support structure, plants in a vertical garden or moss on bioreceptive concrete. The system determines how the vegetation is installed, watered and maintained.

For a commercial building, the choice starts with the existing facade or building design, available space and maintenance requirements. Respyre advises on facade greening with moss concrete, climbing plants and vertical gardens. This guide helps you compare the options. Explore our [moss facade services](https://gorespyre.com/mosscrete/) to see the applications Respyre offers.

## Which green facade systems are available?

The key difference is where the vegetation grows: in a root zone at the foot of the wall, in modules attached to it or directly on a bioreceptive surface. Each approach brings different facade and maintenance requirements.

Comparison of three facade greening systems

| System | Construction and water | Maintenance | When to consider it |
| --- | --- | --- | --- |
| [Mosscrete](https://gorespyre.com/mosscrete/) | Moss grows on bioreceptive concrete, as a finish or within a facade system. Rainwater and humidity support growth; assess water availability for each site. | Periodically inspect moss coverage, moisture conditions, drainage and the facade. | Where the substrate or panel assembly is suitable and a gradually developing moss facade fits the brief. |
| [Climbing plants](https://gorespyre.com/climbing-plants/) | Plants grow from a root zone along cables, trellises or a frame. Suitable soil and sufficient water are required. | Care for and prune plants; inspect supports and the water supply. | Where there is room for roots and supports and seasonal growth suits the intended appearance. |
| [Vertical garden](https://gorespyre.com/vertical-gardens/) | Plants grow in modules attached to the facade. Most systems need a water supply or irrigation provision. | Check plant health, irrigation, supports and drainage; prune and replace plants where needed. | Where visible planting from the start and variety are priorities, and ongoing care can be arranged. |

## What determines the cost of facade greening?

Costs depend on the full scope: preparing the facade, selecting the system, installation and maintenance. Compare proposals that cover the same work and period of use.

- **Facade area and layout.** Large, continuous surfaces are more efficient to work on. Windows, corners and recesses require custom detailing.
- **Substrate and structure.** The condition of the wall determines preparation. Roughening, repairs or an additional panel assembly affect installation.
- **Access.** Height, working space and access for equipment determine how installation and later inspections can be carried out.
- **Water and planting.** The system and location determine the water provision, plant selection and care required.
- **Related building work.** Include facade insulation, renovation or prefabrication in the comparison when they form part of the project.
- **Maintenance.** Agree who carries out inspections, pruning, any replacements and upkeep of water systems.

## Can an existing building have a green facade?

Yes, facade greening can be part of a renovation, provided the existing wall and proposed assembly are suitable. Assess the substrate, load-bearing capacity, facade details and access first.

Mosscrete plaster needs a coarse mineral substrate, such as concrete or masonry. An overly smooth surface needs roughening first. Direct plastering is unsuitable on a non-mineral substrate; a facade panel system is an alternative to assess. Where insulation is being added, greening must fit the complete facade assembly. See the [insulated facade application](https://gorespyre.com/insulated-panels/) and the [conditions for Mosscrete](https://gorespyre.com/request-a-quote/).

## What changes for a new building?

In a new build, vegetation can be coordinated with the structure, facade layout and water supply from the design stage. This allows greening to be combined with prefabricated panels or another planned facade assembly.

Provide maintenance access and align the programme with growth. The moss coating is applied between March and September. [Sandwich panels with Mosscrete](https://gorespyre.com/sandwichpanel/) are one application for a new building; the final choice depends on the design.

## When is Mosscrete less suitable?

Mosscrete needs additional consideration where sun and wind exposure are high, moisture is limited or the facade cannot carry the selected cladding. Shaded facades are most suitable. South-facing walls may need additional design and irrigation measures.

A non-mineral substrate cannot receive Mosscrete plaster directly. Many small surfaces and interruptions make installation more complex. If an immediately planted wall or flowering vegetation is the main priority, compare vertical gardens and climbing plants as well: a moss facade develops gradually.

## What maintenance does a green facade need?

Every green facade needs care suited to its system and location. Mosscrete focuses on periodic inspection; climbing plants and vertical gardens also need plant care.

For a moss facade, inspect coverage, moisture conditions and drainage. Climbing plants also require attention to pruning and supports. In a vertical garden, irrigation and individual plant health need attention. Agree access and responsibilities in advance.

## The Hague: combining an existing facade with insulation

At Spui in The Hague, a commercial building was redeveloped for Leiden University. Ground-based greenery was not a viable option and the facade needed external insulation. The project used a bioreceptive surface over 220 m² as part of the insulated facade system.

The lesson for your project: where facade renovation and insulation are already planned, assess greening alongside that work. Read the [The Hague project description](https://gorespyre.com/commercial-real-estate-den-haag/).

## Kortrijk: integrating greening into a prefabricated new build

At the industrial building in Kortrijk, 450 m² of a facade made with prefabricated sandwich panels was greened with Mosscrete. The application is linked to rainwater harvesting. Here, greening formed part of the new facade from the outset.

The lesson for your project: in a new build, the panel assembly and water provision can be designed together. The Hague shows work on an existing building; Kortrijk shows how Mosscrete was included in prefabricated construction. Read the [Kortrijk project description](https://gorespyre.com/west-flanders/).

## How do you choose a service for your commercial building?

Start by describing your facade, growing conditions and maintenance requirements. Then work with Respyre to choose an approach that fits.

- **Describe the building.** Explain whether it is a renovation or new build, which substrate is present and whether insulation is part of the brief.
- **Describe the site.** Share its orientation, sun and wind exposure, available root space, water supply and access.
- **Define the appearance and care.** Do you want a gradually growing moss layer, seasonal greenery or a planted wall? Establish which care you can arrange.
