Case for change

Population growth in Australian cities is influencing government policies around sustainable living and urban greening within high-density living areas. The growing interest has been encouraged by increasing availability of technologies that make their construction easier and more economical. As such, there is an increasing demand for skills in developing rooftop gardens and green walls.

Industry consultation has identified the need for skills standards and training in the design, construction, installation and maintenance of green walls and rooftop gardens in Australia.

The Australian Industry Skills Committee (AISC) approved this project, out of the 2019-2022 IRC Skills Forecast and Proposed Schedule of Work.

Skills Impact and the Amenity Horticulture, Landscaping and Conservation & Land Management Industry Reference Committee (IRC) will manage this project, consistent with the 2012 Standards for Training Package Development.

Project Plan

Green walls and rooftops help to cool our cities, manage storm water and improve air quality. These ‘living’ roofs and walls are growing with popularity, as they offer city residents healthy, environmentally responsible buildings. The growing interest is encouraged by government policy, as well as increased availability of technology that makes their construction and maintenance easier and more economical. This is opening up job opportunities in industry, with skills and knowledge adapting to respond to the needs of this specialised sector.

Landscapers are familiar with building constructions, such as garden beds and tree landscapes at ground level. However, the skills and knowledge required to design, construct, install and maintain these sorts of infrastructure on walls and roofs is specialised. Consideration needs to be given to drainage and filtration systems, soil/media and plant selection, waterproof barrier selection, nutrient requirements, working at heights on elevated work platforms, and local government legislation. Knowledge of environmental factors and microclimates is also important, as well as how much weight a structure can bare. The unique skills requirements of workers in this sub-sector will be identified as part of this project and reflected in the national skills standards, to support the skills development and career opportunities in this growing occupation.

Australian city dwellers will be all too familiar with the fierce heat that can be experienced on a hot summer’s day, when surrounded by closely constructed buildings, concrete and other solid surfaces. Green walls and roof tops can offer respite from these ‘urban heat islands’, where space for traditional parks is limited.

In recent years, Australian city councils have pledged to increase green walls and rooftop gardens to reduce the urban heat island effect. Melbourne has a Green Our City Strategic Action Plan, Sydney has the Green Roofs and Walls Policy, and Brisbane has introduced a non-statutory New World City Design Guide – Buildings that Breathe.

Project Scope

Units of competency will be reviewed and revised if necessary to address the additional skills and knowledge required for the design, construction, installation and maintenance of green walls and rooftop gardens in Australia.

Stakeholder Consultation Process

A list of key stakeholder organisations has been identified for this project. Skills Impact will ensure contact is made with each of these organisations during the development of this project to seek their involvement and their views on the draft qualifications, skill sets and units.

If you are aware of an organisation that you think should be involved, please contact the project team to ensure they are contacted by us.

Of course, all and any interested industry participants are encouraged to engage in the consultation of this project, when the draft qualifications, skill sets and units are available for feedback via this webpage and workshops that take place around Australia. Consultation is not limited to the organisations on this list. This list simply helps us to identify those organisations that, because of their industry role, size or specialty, are likely to have a key interest in the development and outcomes of this project.

 

Development

Green walls and rooftops are increasing in popularity for their capacity to cool our cities, manage storm water and improve air quality. Thanks to the encouragement of government policy and improved availability of the technology to construct and maintain green walls and rooftop gardens, job opportunities are opening up.

Specialised skills and knowledge are required to design, construct, install and maintain these sorts of infrastructure. As part of this project, work is now underway to review skill sets and units of competency to address these skills needs.

In September, a workshop was held with stakeholders and subject matter experts who work directly in this field. At this meeting the required functions, roles and tasks involved to create and maintain green walls and rooftop gardens were discussed. It was identified that the skills required for design vary to those needed for construction. Education for the maintenance of green walls and rooftop gardens was also identified as an important area.

Consultation Workshops – Registrations Open!

Thank you to those stakeholders that have been involved and provided feedback and advice so far. The draft skill sets and units of competency will be made available on this webpage for public consideration and feedback early November 2019 (under the ‘Drafts Available’ menu above). Face-to-face consultation workshops will also take place across states, with a webinar planned for those unable to attend in person. Registrations for these workshops are now open.

Drafts Available

Green walls and rooftop gardens offer city residents healthy, environmentally responsible buildings, helping to cool our cities, manage storm water and improve air quality. With city councils encouraging this trend through policy and the increased availability of technology, these features are becoming more common, opening up job opportunities in the sector. As industry adapts its skills and knowledge to the unique requirements of green walls and rooftop gardens, it’s important to ensure this is captured in the skills standards for the sector.

Three new skill sets and three new units of competency have been developed as part of this project, covering the skills and knowledge required for individuals to design, construct and maintain rooftop gardens, green walls and green facades.

Thank you to those who provided feedback on the draft units of competency and skill sets that were made available on this webpage for feedback from 30 October – 1 December 2019. 

During this time, feedback was collected via the online feedback hub, five face-to-face consultation workshops, a webinar, and email. The drafts, including any comments made on the feedback hub, are still available for viewing below.

Feedback will inform the work on the final drafts which are expected to be available for industry validation in February 2020. A summary of the feedback and how it was addressed in the final drafts will also be available.

Validation

Roof gardens, vertical gardens, and green facades offer many benefits for city residents, helping to cool our cities, manage storm water and improve air quality. Such infrastructure is becoming more common, as technology and council policies make it easier to build. This is opening up job opportunities in the sector, requiring industry to adapt its skills and knowledge to the unique context of the work. Capturing the skills standards required to design, construct, install and maintain such infrastructure is essential to supporting job roles in this field.

Thank you to those who provided feedback on the final draft skill set and units that were made available on this webpage for feedback from 7 February – 1 March 2020.

They have been revised to include terminology consistent with that used within industry, which is reflected in the updated proposed titles and throughout the documents. Concern was raised during consultation that the scope of the proposed unit AHCGRIXX1 Design rooftop gardens, green walls and green facades was too large as it contains 36 Performance Criteria (PC) and a learner would have to design for three different situations. Consultation with Subject Matter Experts confirms that the unit needs to be kept as one unit as it is common for workers to use a range of building styles and techniques across one project.

Subject Matter Experts also considered the issue of prerequisites for the individual units as well as entry requirements for the skill sets. The units are proposed to be added as elective units to a number of existing qualifications, none of which currently have entry requirements, meaning a person could undertake the units (and RTOs could package the individual units into a short course) from existing qualifications without entry requirements. As an alternative to entry requirements or prerequisites, wording has been incorporated into the units and skill sets to indicate a level of experience may be necessary, and RTOs can and should determine individual learner capabilities for enrolment. This will keep the units and skill sets accessible to a wider range of potential learners.

The final drafts will shortly progress through to the Finalisation stage of the project which includes quality assurance of the documents and review and feedback from the State/Territory Training Authorities. They will then be forwarded to the Amenity Horticulture, Landscaping and Conservation & Land Management Industry Reference Committee (IRC) for consideration and sign off, before being submitted to the Australian Industry and Skills Committee (AISC) to consider and approve for publication on training.gov.au.

Finalisation

Roof gardens, vertical gardens and green facades provide a range of environmental, social, and aesthetic benefits to urban populations. Australian city dwellers will be all too familiar with the fierce heat that can be experienced on a summer’s day, when surrounded by closely constructed buildings, concrete and other solid surfaces. With limited space for traditional parks, this kind of infrastructure can offer respite from ‘urban heat islands’, along with the ability to improve air quality and help manage storm water. Australian city councils have recognised the appeal, developing plans and policies to increase the number of roof and vertical gardens. This support, combined with better access to technology, has helped green infrastructure to become more popular and open job opportunities. 

While job roles in this area draw on skills and knowledge relating to horticulture and landscaping, specialist skills and knowledge are required for this unique context. The design, construction and maintenance of green infrastructure requires consideration of a range of factors, including how much weight a structure can bear, safety working at heights, access points, nutrient requirements, installation of waterproof barriers, drainage and filtration systems, environmental factors and microclimates, and local government legislation. 

Thanks to the contributions of those who participated in this project, the unique skills required for work with green infrastructure have been captured in three units of competency and three skill sets. 

The skills sets and units of competency have all been carefully considered and reflect what I, and the industry, consider to be key in training those entering the industry. I currently employ staff who work in this field and ultimately would like to have staff formally trained in these skills standards prior to commencing employment, in addition to the practical/onsite training that currently occurs. 

– Michael Casey, Director Evergreen Infrastructure 

The units and skill sets were published on the training.gov.au website on 24 December 2020, within the AHC Agriculture, Horticulture and Conservation and Land Management Training Package. They are available for use by registered training organisations (RTOs).

Key Outcomes
  • Three skill sets developed to cover the knowledge and skills required to:
    • Design roof gardens, vertical gardens and green facades for commercial and or residential projects, in consultation with building, landscape and horticultural professionals.
    • Safely construct roof gardens, vertical gardens and green facades for commercial and or residential projects.
    • Maintain green infrastructure specific to commercial and or residential roof gardens, vertical gardens and green facades.
  • Five units developed to capture the skills and knowledge required to:
    • Design roof gardens
    • Design vertical gardens and green facades
    • Construct roof gardens
    • Construct vertical gardens and green facades
    • Maintain roof gardens, vertical gardens and green facades.
Summary of consultation

The units and skill sets were developed with guidance from a group of Subject Matter Experts (SMEs). The broader industry were then consulted on the draft documents at two different stages – the ‘Drafts Available’ and ‘Validation’ stages – with feedback collected through consultation workshops, site visits, the online feedback hub, email, telephone and online surveys. A summary of the feedback received during these stages and how it was considered and applied can be downloaded below.

 

The draft skill sets and units were then reviewed by the Amenity Horticulture, Landscaping and Conservation and Land Management IRC. The IRC considered draft recommendations from the project, and after further consultation with industry experts, decided more work was needed to describe the skills being trained, facilitate the ease of delivery, and ensure learners have adequate opportunity to gain the required competencies.

The drafts were updated in consultation with industry experts and made available for an additional two rounds of public consultation, from 6 – 19 July and again from 29 July – 12 August 2020. Feedback was sought on key updates to the draft units for the design and construction of roof gardens, vertical gardens and green walls, and the development of these skills standards from two units to four, so that the different knowledge and skills required for design and construction of roof gardens compared to green walls and facades could adequately be covered. A summary of feedback collected during the additional round of the ‘Drafts Available’ stage is available for download below. A summary of the additional ‘Validation’ phase will be available soon.

 

 

The skill sets and units were endorsed by the Australian Industry and Skills Committee (read the communique) and State and Territory Ministers after undergoing an edit and equity and independent quality assurance process and consideration by the State/Territory Training Authorities (STAs/TTAs). A Case for Endorsement was submitted alongside the draft skill sets and units, including a rationale of why these changes are needed and evidence of industry support.

Companion Volume Implementation Guide

A Companion Volume Implementation Guide has also been produced to assist industry and registered training providers (RTOs) deliver the skill sets and units. It contains key information to help trainers adapt to any new changes, as well as additional information about the impacts of regulation and licensing implications and workplace health and safety on their training.
