To deliver low carbon, resource efficient and environmentally sensitive places.
To lead environmental performance across Landcom developments by committing to being carbon neutral and water positive, with zero waste and net positive ecological outcomes by 2028.
Landcom’s Climate Resilient Places pillar is focused on a leadership goal to ‘enable carbon neutral, water positive, zero waste and net positive ecological outcomes by 2028’.
This leadership goal was developed to reflect Landcom’s contribution towards the Paris Agreements2 long-term goal of keeping the increase in global average temperature well below 2°C, the United Nations Sustainable Development Goals3, and reducing the impact of shocks and stresses to communities and infrastructure as identified by Resilient Sydney4 (part of the Rockefeller Foundation 100 Resilient Cities Program), such as extreme weather and water crises.
Within this pillar Landcom focusses on environmental sustainability and resilience. It encompasses environmental management and the adoption of independent third-party rating tools and certifications, engaging with our supply chain, supporting communities to reduce their operational costs of living, and developing our projects in a way that reduce impacts on the environment.
Environmentally sustainable communities are balanced in meeting the needs of the natural, and urban environment. They take into account the needs of people today, and the needs of our future generations. Landcom believes that the built environment should incorporate green spaces and retain a connection to our natural habitats, for the benefit of the environment, and our communities.
Landcom addresses environmental sustainability through the following focus areas:
• Energy & Emissions
• Environmental Management
• Climate & Resilience
• Waste & Materials
Each of these focus areas includes a suite of targets to measure our success.

Toward the end of FY19 Landcom launched its first Sustainability Rebate to home buyers at Macarthur Heights, and in FY20 we saw the first claims for this Rebate. This is a new incentive to encourage greater sustainability and resilience of new homes in Landcom communities.READ MORE
Every Landcom project is unique and requires a bespoke approach to environmental sustainability. We use the sustainability modelling tool PRECINX5 to identify opportunities for performance improvement across our Energy & Emissions and Water targets.
Our approach to Energy & Emissions includes influencing the reduction of greenhouse gas (GHG) emissions (stationary and transport) at a precinct scale across our communities and influencing the onsite production of renewable energy. We approach Water in a similar way, by looking at the reduction of potable water use across a precinct and identifying opportunities for recycling and reuse.
We also set ourselves targets to limit stormwater discharge pollutant loads from our sites. This minimises downstream water quality impacts in the communities we develop. Urban stormwater modelling software such as MUSIC6 is used to measure pollutant loads across our projects.
5 Landcom commissioned the development of PRECINX in 2009 as an accurate predictive modelling tool of greenhouse gas emissions, water consumption, transport outcomes and cost of living impacts of development in the built environment. Landcom now licenses the tool, as do many other developers, utilities, and local and state government organisations.
6 MUSIC Overview (2018) https://ewater.org.au/products/music/music-overview/
Landcom is committed to adopting independent third-party rating tools and certifications or exceeding regulatory requirements. We believe it is important to have independent verification of our sustainability performance. This is aligned to our targets for Environmental Management. Our preferred rating tools are outlined below.7
For our FY20 activities related to Environmental Management, see Environmental Management Performance Results below.
7 In some instances Landcom may also agree to use other rating tools in lieu of, or in addition to, those outlined. This is at Landcom’s discretion.
Landcom’s approach to Climate & Resilience includes understanding our physical and transition risks to climate change and its impacts, ensuring our communities are adaptable to change, addressing known risks such as urban heat island,8 and maintaining our commitment to enhancing local biodiversity and ecology.
During FY18 Landcom built its internal capacity for assessing asset exposure to physical climate change risks. This included adopting a risk assessment framework, Resilience-In-Design checklist, prompting project teams to consider common climate risks during the early phases of a project’s design, and completing community resilience plans9 designed to enhance the resilience of our communities in the way they live day to day.
In FY19 we expanded our remit and sought to better understand our physical and transition risks to climate change. A gap analysis aligned with the Task Force on Climate-related Financial Disclosures Recommendations and 2019 Global Real Estate Sustainable Development Resilience Module was undertaken to determine Landcom’s current level of preparedness for the transition risks of climate change, and how Landcom currently addresses physical risks at its assets. This included business wide stakeholder engagement and a review of Landcom’s systems and processes. The results found that Landcom is comprehensively addressing the physical risks to assets, and there is opportunity to enhance our preparedness to transition risks.
In FY20 Landcom has commenced reporting against the Task Force on Climate-related Financial Disclosures Recommendations. This is a key component of our approach to addressing climate change physical, transition and social risks.
We are already taking steps to address known physical risks immediately, which includes reducing the effects of urban heat island across our new communities. As one of Sydney’s most significant climate-related risks, early design interventions that address urban heat reduction are essential in the creation of new communities. We also continue to invest in research to address urban heat, including through Landcom funded Roundtable projects (see Research Investment).
Finally, Landcom seeks to address resilience in the natural environment. This is achieved when we maintain strong diversity of our ecological systems. We abide by legislative requirements including the Commonwealth Environmental Protection and Biodiversity Conservation Act, and the NSW Biodiversity Conservation Act when addressing areas of biodiversity. When we purchase biodiversity offsets for our development approvals, we use the NSW State Government BioBanking Scheme which commits land owners to enhancing and protecting the biodiversity values of their land. We use our Biodiversity Calculator to measure the quality and quantity of ecological communities beyond any legislative requirements, pre- and post-development. We aim for a net positive outcome at the completion of our projects.
For our FY20 performance against our Climate & Resilience targets, see Climate & Resilience Performance Results below.
8 Urban Heat Island Effect (2018) http://www.cityofsydney.nsw.gov.au/vision/towards-2030/sustainability/carbon-reduction/urban-heat-island
9 Eligible assets include those that have been assessed for climate change risks.
Landcom’s environmental leadership goal for 2028 includes enabling zero waste communities. To do this we are advocating for responsible use of resources, and diversion from landfill. Landcom has long held a waste diversion from landfill target, which is maintained in our Sustainable Places Strategy.
While we are focused on reducing waste within our own offices it is construction waste that is material to Landcom’s operations. As part of our ongoing commitment to reduce waste and increase responsible materials use, Landcom continues to engage with our site superintendents and principal contractors to reduce, reuse or divert waste from landfill.
We also include the responsible sourcing of timber for all construction works within our approach. This increases engagement with our supply chain, and supports our work underway within our Accountable & Collaborative Places pillar.
For our FY20 performance results against our Waste & Materials targets, see Waste & Materials Performance Results below.
Our Sustainable Places Strategy identifies a number of initiatives as future opportunities to enhance our Environmental Management, Climate & Resilience, and Waste & Materials focus areas. This includes:
understanding Landcom’s role for improving air quality within our communities
determining the value of adopting a Landcom materials Red List
establishing how life cycle assessments may improve our supply chain and reduce embodied carbon at our projects.
In FY20 we progressed investigations into how Landcom can positively influence air quality within the areas we operate, and a strategy for this, including actions and targets, is currently in development. As part of our FY19 materiality review, air quality became a material for Landcom as part of Natural Capital Protection & Management. As we finalise our approach to addressing air quality, we will update our management approach.
We continued to support research at the Centre for Smart Modern Construction to develop methodologies for estimating embodied carbon in construction supply chains. We see a future for tools such as this which will help us to track actual embodied carbon through the delivery of our community infrastructure and civil works.
See below our performance results for each of the reporting areas within our Climate Resilient Places Pillar.
Landcom’s Sustainable Places Strategy addresses Climate & Resilience. This focus area forms part of our Climate Resilient Places pillar and is a representation of our commitment to delivering resilient communities that balance ecological outcomes, reduce climate related stresses and build community resilience.
The below table outlines our FY20 performance against our Climate & Resilience Targets.
All new projects to undertake a Climate Resilience Assessment.

Greenfield Projects: 50% project site area
Renewal or High Density Projects: 20-50% project site area (calculation in accordance with Green Star Communities)
In FY20 Landcom continued to collaborate with consulting firm AECOM to enhance our current project portfolio’s resilience to climate-related risks, and increase our internal capacity to ensure all future projects are resilient.
We complete climate change resilience assessments for all new projects. We use a consistent pro forma to assess Landcom projects, which was developed in 2018 in line with Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) climate projections for 2030 and 2090.11 We also use our Resilience-in-Design checklist to guide informed decision making for projects during the concept design of a development.
All our new projects at the launch of the Sustainable Places Strategy, and all relevant legacy projects, now have climate risk assessments in alignment with the IPCC AR5 Representative Concentration Pathways 4.5 and 8.5 climate projections, and adaptation plans developed to reduce the physical and social risks of climate change to the project and community.
All new projects identified as in scope at the commencement of the Sustainable Places Strategy now have completed Climate Resilience Assessments and Climate Adaptation & Community Resilience Plans, bringing us into full attainment of these targets.12
In FY20 several new projects were announced, which also have completed or scheduled assessments, including Fennell Bay, Glenfield and Queenscliff. As our Schofields project is in proximity to the SMNW Places Tallawong precinct it will leverage that site’s climate risk assessment.
“Extreme risk” of extreme heat is common to almost all Landcom sites, which is consistent with the top risks to Sydney identified by Resilient Sydney.13 This finding confirms the importance of Landcom’s priority to reduce or mitigate the effects of urban heat island and build community resilience to heat at all new projects. Bushfire is also a consistent risk across Landcom’s project portfolio.

Heat continues to be a major stress for many cities across Australia, as confirmed by our climate change risk assessments. Landcom’s commitment to reduce urban heat island effect (UHI) will contribute to reduced risk of extreme heat at our projects. This will enhance the resilience of our communities and the residents that live there.
Three new projects are in scope for our Urban Heat Island Reduction target in FY20, including Tallawong, Hills Showground and Macarthur Gardens North. Macarthur Gardens North is achieving the target through the retention of bushland on the site. Tallawong and Hills Showground were sold14 to the private sector with conditions of sale to deliver on these targets. All other new projects announced during the year remain out of scope as they progress through the masterplan phase, and we are aiming to achieve our UHI target.
14 Contract of Sale has been exchanged, the sites have not settled.
FY20 is the third year Landcom will report the contribution we make to biodiversity and ecological systems. To support the business in measuring this, in 2018 we developed our Biodiversity Calculator based on the Green Building Council of Australia’s change in ecological value calculator provided in Green Star tools.
Landcom’s Biodiversity Calculator is designed to measure the change in quality and quantity of biodiversity at a given project site, from pre- development to post development. The calculator goes beyond just assessing high-value and significant biodiversity (which legislation requires to be conserved) and factors a broader spectrum of biodiversity value into the assessment. Depending on the level of quality and quantity change, the calculator determines whether a net positive or net negative impact has been achieved. It is possible to have a net positive outcome in biodiversity, despite a reduction in physical area — if the quality of that area has been significantly improved.
The scale provided by the calculator is as follows:
We acknowledge that land development and retention of biodiversity are sometimes at odds. Despite our best efforts to retain existing flora and fauna at all our sites, sometimes this is not possible. However, we do aim to always have a net positive outcome at our projects. Some methods we may use include biodiversity offsets,15 and restoration works such as improving eroded riparian corridors to full health.
Projects in scope for FY20 include precincts within the SMNW Places program,16 Macarthur Gardens North and Edmondson Park, of which 71% are currently making a net positive biodiversity contribution. Overall 23.86ha of biodiversity will be protected and restored by National Parks, local councils or other entities aligned with legislative guidelines.
Edmondson Park and Macarthur Gardens North will reduce the overall area of onsite biodiversity from pre-development to post-development, but return net positive outcomes due to the preservation of significant good quality habitat.
At each of these projects native habitat offsets will be employed to manage the reduction in habitat area.
The remaining sites assessed form part of the SMNW Places program. Each site is co-located with a metro station being delivered by Transport for NSW (TFNSW). TFNSW is also the land owner of these projects, and Landcom has been appointed as the master developer for the surrounding communities. Of these, Kellyville and Bella Vista will reduce the overall onsite area of biodiversity, however return a net positive outcome. Conversely, Epping is forecast to contribute a very good (net positive) change in biodiversity value, as the site design doubles the available biodiversity area compared to pre- development. Tallawong and Hills Showground have a poor (net negative) change in biodiversity. As Landcom is not the landowner of the SMNW Places sites, management of biodiversity offsets and other approvals is beyond our operational control, and is undertaken by TFNSW. Landcom will continue to review opportunities to elevate the performance of SMNW Places sites through project divestment and delivery strategies.
At each of these projects native habitat offsets will be employed to manage any reduction in habitat area.

Landcom’s Sustainable Places Strategy addresses Energy & Emissions. This focus area forms part of our Climate Resilient Places pillar and is a representation of our commitment to delivering energy efficient communities that reduce greenhouse gas emissions, advance uptake in renewable energy technologies, and reduce the cost of living to residents.
All new projects modelled to reduce greenhouse gas (GHG) emissions at a precinct scale (transport & stationary) by 50% against 2016 reference case (CCAP PRECINX).
FY20: 13% portfolio weighted reduction
Forecast: portfolio weighted reduction (%)
5% of predicted precinct energy demand supplied from onsite renewable energy, where site constraints permit.
Our Emissions Reduction target seeks to minimise stationary and transport emissions through the adoption of energy efficient design, renewable energy infrastructure, transport mode split and parking strategies, and uses incentives to encourage efficient building systems and appliances. The emissions reported are the predicted operational emissions of a masterplan at completion and are calculated using the sustainability modelling tool PRECINX and a NSW metro average baseline of 2016. The global warming potential account factors align to the National Greenhouse and Energy Reporting (NGER) Act.
In FY20 Tallawong and Hills Showground were sold to the private sector with conditions of sale to deliver on these targets. As contracts have exchanged, however not settled, we have articulated performance results for these as ‘commitments’. When future development planning approvals are provided by relevant consent authorities for these precincts, and Landcom settles on the projects we will report any shift between the commitments made by the proponents, and the actuals achieved.
Across these two sites, the aggregated emissions reduction agreed via contracts of sale is 13%, compared to the metro average. Both sites are relatively constrained, and dominated by high density residential land uses. In isolation this makes it challenging to attain a 50% emissions reduction, however it should be noted the sites are part of the broader SMNW Places program and as more sites are delivered the aggregated average performance is forecast to significantly improve.
Throughout the reporting period Landcom has also continued to engage with the successful proponent of these sites. Through this engagement process, the developer has been able to elevate the BASIX Energy scores from a building code minimum compliance of 25, to a certified 33 for most apartments at Tallawong. The average NatHERS rating for those apartments is also over 7 Stars.
Landcom anticipates that industry demonstration of beyond BASIX compliance will provide market confidence that Landcom’s targets are achievable, and contribute value to developers of high density residential projects.
New projects, or individual precincts within ongoing projects currently in the planning and design stages are also in scope for FY20 reporting.17 Forecast results include SMNW Places precincts of Kellyville, Bella Vista and Epping precincts, and Edmondson Park with a weighted average GHG emissions reduction of 49%18 (see Figure 1).
New higher-density projects continue to present the greatest challenge in attaining material emissions reductions, due to the reduced site area and roofspace available to incorporate renewable energy technologies in a cost-effective way.
Over the past year we have dedicated significant effort to improving how high-density projects can respond to emissions reductions. Overall, accounting for commitments made in exchanged projects, and those which remain in our forecast, the comparison represents a 13% improvement.
In FY20 residential dwellings continued to be our most material emissions source, following by transport and non-residential land uses. Non-residential emissions emerged in FY20 as a material emission source due to the inclusion of the Bella Vista precinct which has a considerable portion of non-residential land uses (see Figure 2). In FY21 we will continue to focus on opportunities to further reduce residential and transport emissions.
While our emissions target is designed to address new projects, in FY20 we sought to make a meaningful impact at projects that have already moved through the planning and design phase. In FY19 we launched Landcom’s first Sustainability Rebate at Macarthur Heights, incentivising residents to build sustainable new homes.
The rebate is designed to be a market-based lever to lower emissions and improve the cost of living in established communities, while driving sales (see Case Study: Sustainability Rebate). In FY20 we saw the first claim against this rebate and look forward to seeing ongoing uptake as new homes become eligible during their construction process.
17 Performance is based on projected performance for all new Landcom projects, until such time as the delivery or divestment strategy for each project is confirmed. At this time, results will become ‘actuals’.
18 Reduction from the reference case. Landcom chooses to use its PRECINX tool for modelling potable water and Greenhouse Gas emission reductions. 2016 reference case is defined as the normalised relevant metropolitan average applied to a masterplan.
Landcom’s onsite renewable energy target is for 5% of total site demand at the precinct scale to be delivered by onsite renewable energy. This extends beyond the inclusion of solar panels on residential homes, and requires a strategic precinct scale response. The intent of this target is to drive innovation and large scale integration of renewable energy sources at the project site.
In FY20 Landcom had two projects in scope for reporting the inclusion of onsite renewable energy, including Tallawong and Hills Showground. Both projects were sold to the private sector with conditions of sale to deliver on this target.
Landcom’s Sustainable Places Strategy addresses Environmental Management. This focus area forms part of our Climate Resilient Places pillar and is a representation of our commitment to deliver communities that achieve or exceed independent third party rating systems or standards.
Our FY20 performance results are presented below. All Environmental Management targets were in scope for reporting.
All projects will adopt the use industry recognised rating tools at a masterplan and built form scale, achieving not less than ‘Australian Best Practice’ equivalent (Green Star preferred).
Out of scope
(Legacy project Green Square awarded 6 Star Green Star Communities rating).
NABERS: Office, Hotel & Retail – Commitment Agreement or designed to 5 Star Energy and Water.
Out of scope.
BASIX energy: Detached & Semi - 60; Low-Rise - 55; Mid-Rise - 45; High-Rise – 40
BASIX water: all dwellings - 60
Out of scope - no certificates approved with dwellings completed in the reporting period.
Green Star, administered by the Green Building Council of Australia, is Landcom’s preferred independent and voluntary rating tool for precincts and built form. Landcom is committed to achieving ‘Australian Best Practice, 5 Star Green Star’ project certifications for all new projects.19
In FY20 Landcom registered Macarthur Gardens North to pursue a Green Star Communities rating, targeting not less than a 5 Star rating. We anticipate sharing our certified results in the coming reporting year. In addition, SMNW Places precincts Tallawong and Hills Showground were sold to the private sector, and included conditions of sale to achieve this target.
19 In some instances, Landcom may seek to use, or require the use of, the Green Star Design & As-Built rating tool.
Landcom adopts the National Australian Built Environment Rating System (NABERS)20 as its preferred independent and voluntary rating system to validate the operational sustainability of eligible nonresidential built form. NABERS measures a building’s operational energy efficiency, carbon emissions, water consumption and waste production on an annual basis, and awards a star rating out of six.
Landcom is committed to requiring a NABERS rating at new projects that include office, retail or hotel built form. A NABERS rating can only be ensured at Landcom projects through collaboration with future building owners and operators through conditional requirements within contracts of sale to future site owners.
Landcom had two projects in scope within the reporting period. This included two SMNW Places precincts Tallawong and Hills Showground which were sold to the private sector, and included conditions of sale to achieve this target.
Landcom had two projects in scope within the reporting period. This included two SMNW Places precincts Tallawong and Hills Showground which were sold to the private sector, and included conditions of sale to achieve this target.
20 What is NABERS? (2018) https://www.nabers.gov.au/about/what-nabers
We measure the energy and water efficiency of homes built by Landcom in accordance with the Environment and Planning Assessment Act Building Sustainability Index (BASIX).21 BASIX is administered by the Department of Planning, Industry and Environment (DPIE), applies to residential developments, and aims to deliver equitable, effective water and greenhouse gas emission reductions across NSW.
BASIX targets are calculated as a percentage of savings against the NSW average benchmarks (being the average per-person water consumption and greenhouse gas emissions levels across the state). These percentage savings are then expressed as a target, i.e. BASIX 50 represents a 50% saving against the benchmark. BASIX assesses a proposed dwelling based on these benchmarks, and takes into account regional variations such as soil type, climate, rainfall and evaporation rates.22
BASIX certificates are generated in accordance with the design of a new residential development, based on the specifications of that building. A BASIX certificate must accompany any development application or complying development application before approval for that building is provided. Once construction is complete a BASIX completion receipt is issued, if an independent certifier confirms the home has been built in accordance with the BASIX specifications. Landcom uses the BASIX completion receipt to validate the percentage of homes within our portfolio designed and delivered in accordance with our targets.
In FY20 we had two SMNW Places precincts in scope, including Tallawong and Hills Showground. Both sites were tendered to market with Landcom’s BASIX targets requested for achievement. Unfortunately we were unsuccessful in negotiating agreement to deliver on Landcom’s targets. However, since the exchange of contracts the successful proponent has demonstrated a willingness to collaborate and achieve higher than compliance BASIX performance. When future development planning approvals are provided by relevant consent authorities for these precincts, and Landcom settles on the projects, we will report any shift between the commitments made by the proponents, and the actuals achieved.
21 What is BASIX? https://www.planningportal.nsw.gov.au/planning-tools/basix
Landcom’s Sustainable Places Strategy addresses Waste and Materials. This focus area forms part of our Climate Resilient Places pillar, and is a representation of our commitment to delivering communities that reduce waste, and source materials responsibly. These focus areas contribute to our leadership goal to enable zero waste communities by 2028.
The below table outlines our FY20 performance against our Waste & Materials Targets.
All new projects divert minimum 95% construction waste from landfill (excluding contamination or hazardous materials).
No new projects in scope.
100% timber sourced for construction (by cost) is Forest Stewardship Council Certified or agreed equivalent (ie Australian Forestry Standards).
No new projects in scope.
Landcom continues to place a high value on transparently reporting our impact on local environments. We are advancing our approach to focus on how we can achieve net positive environmental outcomes, including zero waste communities.
In calculating our waste diversion from landfill target we exclude hazardous waste and contamination volumes from the figures to align more closely with the standards set out in the Green Star rating tools.
In FY20 Landcom we had two projects in scope for reporting against our Waste diversion target. This included Tallawong and Hills Showground, which were all sold to the private sector with conditions of sale to deliver on this target.
Existing Landcom projects that generated waste in FY20 reported a 97% diversion from landfill. The majority of waste was generated at Airds, Lachlan’s Line and Oran Park, with fill (soil) and virgin excavated natural material (VENM) being the most significant recycled materials. As these projects are operating under contracts that pre-date the adoption of our Sustainable Places Strategy, they are technically out of scope, however we are disclosing their waste diversion attainment in FY20 for completeness.
Consistent and accurate waste reporting remains a challenge across the development industry. In FY19 we commenced the development of an online data collection process for waste to mitigate the need for manual ‘paper’ based workflows. The process being developed is part of the Work Health and Safety reporting portal and is in the testing phase. We anticipate moving to user acceptance testing and roll out in FY21.
In FY20 there were two projects in scope for reporting against our target for 100% Chain-of-Custody Certified timber. This included the SMNW Places precincts Tallawong and Hills Showground, which were all sold to the private sector with conditions of sale to deliver on this target.
Through negotiations at both sites Landcom accepted a contractual target of 95% Chain-of-Custody certified timber is deemed equivalent, as it aligns with the Green Star rating credits the developer is also required to target. As such we are reporting attainment of this target for both sites.
Landcom’s Sustainable Places Strategy addresses Water. This focus area forms part of our Climate Resilient Places pillar and is a representation of our commitment to delivering communities designed for best practice water sensitive urban design which actively conserve potable water. These focus areas contribute to our leadership goal to enable water positive communities by 2028.
The below table outlines our FY20 performance against our Water Targets.
Water Sensitive Urban Design strategy for all projects, pollutant discharge loads not to exceed Nitrogen 45, Phosphorus 65, Suspended Solids 85, Gross Pollutants 90.
All new projects modelled to reduce mains potable water demand by 50% at the precinct scale, against a 2016 reference case (CCAP Precinx).
weighted portfolio reduction
Forecast: Weighted portfolio reduction (%)
Landcom views Water Sensitive Urban Design (WSUD) as integral to the sustainable water cycle management of our projects. WSUD can include the rehabilitation and protection of natural waterways, design elements such as wetlands, rain gardens, water harvesting and storage and efficient fittings, and alterative water sources such as recycled or blackwater.
In FY20 Macarthur Gardens North, Edmondson Park and SMNW Places precincts of Tallawong, Hills Showground, Kellyville, Bella Vista and Epping were in scope for reporting against our WSUD target. All projects either achieved or exceeded Landcom’s WSUD targets.
The Macarthur Gardens North site includes a riparian and biodiversity corridor that will undergo enhancement works, with a focused WSUD approach.
Our potable water reduction target seeks to reduce the use of unnecessary potable water and improve the efficiency of potable water that is used. The potable water consumption reported is the predicted operational consumption of a community at completion and is calculated using the sustainability modelling tool PRECINX.
During the reporting period the SMNW Precincts of Tallawong and Hills Showground achieved a 39% reduction based on commitments in the sale contract. As contracts have exchanged, however not settled, we will be articulating performance results for these as ‘commitments’. When future development planning approvals are provided by relevant consent authorities for these precincts, and Landcom settles on the projects we will report any shift between the commitments made by the proponents, and the actuals achieved. The typical strategies used to achieve the target is to maximize the water harvesting, and adopt higher efficiency appliances and fittings in built form.
We also report our forecast for new projects, and individual precincts within ongoing projects currently in the planning and design stages.23 Across Landcom projects residential land uses continue to dominate potable water consumption, which is consistent with our operations predominantly as a residential developer (see Figure 6).
The weighted average potable water reduction forecast for new projects is 52%24 (see Figure 7) which is in line with FY19. The residential component of our new project portfolio is forecast to achieve 51% potable water reduction (consistent with FY19 forecasts), and non-residential water reductions have improved to 54% reduction from 23% in FY19. This improvement in forecast performance is due to the SMNW Places Bella Vista precinct coming into scope. The site is forecast to achieve full attainment of Landcom’s NABERS water targets across the 150,000m2 commercial gross floor area. This assumption is based on successful uptake of Landcom’s NABERS targets at Tallawong and Hills Showground.
New projects without access to recycled water present Landcom with the greatest challenge to meet our targets. Without access to recycled water infrastructure, potable water reductions greater than 50% at the precinct scale become technically challenging, and infrastructure such as private grey and blackwater treatment systems can ultimately have a negative impact on cost of living for our residents. Despite the challenges this presents there are also opportunities for innovative design, partnership and technology solutions.
23 SMNW Places precincts Kellyville, Bella Vista and Epping, Edmondson Park and Macarthur Gardens North.
24 Reduction from the reference case. Landcom chooses to use its PRECINX tool for modelling potable water and Greenhouse Gas emission reductions. The reference case is defined as the normalised relevant 2016 metropolitan average applied to a masterplan.
