What Are Mesh Blocks & How Are They Used in Real Estate

What Are Mesh Blocks & How Are They Used in Real Estate

What are Mesh Blocks?

As defined by Australian Bureau of Statistics (ABS), mesh blocks are the smallest geographical area of the Australian Statistical Geography Standard (ASGS) and ABS’s classification of Australia into a hierarchy of statistical areas.

Mesh Blocks are essentially a set of geographic boundaries designed to segment Australia into very small areas. These boundaries are used to apply a systematic grid over the entire country, dividing it into tiny sections called Mesh Blocks.

Each Mesh Block is a polygon that outlines a specific piece of land, which can range from a single block in a city to a vast, sparsely populated area in the countryside.

In 2021, the ABS reported 368,286 Mesh Blocks covering the whole of Australia without gaps or overlaps.

Mesh Block design

Mesh Blocks for the current ASGS Edition 3 are designed according to a standard set of design criteria first developed for ASGS 2011.

Most Mesh Blocks are designed to contain 30 to 60 dwellings, although some low dwelling count Mesh Blocks exist. They are permitted in order to account for other design criteria.

The reasons for the minimum dwelling count of Mesh Blocks is so they’re small enough to aggregate to a wide range of areas, allow comparisons between geographic regions but also prevent accidentally exposing confidential information of individuals or businesses.

 

Mesh Block changes

Mesh Blocks are updated (or redesigned) every 5 years to stay relevant.

Mesh Blocks for the current ASGS Edition 3 was redesigned to ensure it still meets the design criteria first developed for ASGS 2011 and reflects the growth and change in Australia’s population, economy and infrastructure.

How are Mesh Blocks created?

Each Mesh Block is assigned a unique numerical code or identifier. This code is used to reference the Mesh Block in statistical databases and geographic information systems (GIS).

The format of the code can vary but often includes digits that signify hierarchical levels of geography.

In Australia, Mesh Block identifiers are 11-digit codes.

The 11-digit Mesh Block code comprises: State and Territory identifier (1 digit), and a Mesh Block identifier (10 digits).

How are Mesh Blocks used?

The ABS does not and cannot provide detailed segmentation data (Census data) that can be directly connected to individuals or businesses. Instead, they provide anonymised and aggregated data against geographic areas. Mesh Blocks are the smallest geographic area that the ABS provide statistics against, so it offers population and dwelling counts at a hyper-local level – this is particularly useful for Census analysis.

These geographic boundaries allow for the aggregation of data from individual Mesh Blocks into larger geographic units, such as suburbs, towns, cities, and regions. This hierarchical structuring makes it possible to analyse data at various levels, from very detailed local information to broader regional or national trends.

Most businesses, including proptechs, looking to augment their analysis with population segmentation data will adopt Mesh Blocks as their default level geographic unit to gain the highest level of accuracy. The popularity of Mesh Blocks mean many businesses will use it for geographic statistics regardless of whether or not the Census data is being leveraged.

What role do Mesh Blocks play in proptech?

Mesh Blocks play a vital role in Proptech, geospatial data, and the real estate industry in Australia. Some example uses include:

Granular geographical data

Since Mesh Blocks are the smallest geographical units, providing a granular level of detail in geographic data, its precision is valuable for analysing real estate trends at a hyper-local level.

Accurate small area statistics

Mesh Blocks are designed to fulfill the need for accurate small area statistics. In Proptech, having precise data at this level is instrumental for understanding localised property markets, demographics, and trends.

Spatial mapping and analysis

Geospatial data, including Mesh Blocks, facilitates spatial mapping and analysis. Proptech platforms can leverage this data to visualise and analyse property-related information, helping users make more informed decisions based on geographical insights.

Enhanced property valuation

Proptech applications can utilise Mesh Blocks to refine property valuation models. The data on dwellings and residents at this level allows for a more nuanced understanding of property values, considering localised factors.

Land use identification

Mesh blocks broadly identify land use, such as residential, commercial, industrial, parkland, and so forth. Land use information is valuable for proptechs involved in property development, urban planning, and investment strategies.

Targeted marketing and outreach

Proptech businesses can use Mesh Block data to tailor marketing and outreach strategies to specific geographical areas. Understanding the demographics and dwelling counts at this level allows for targeted and effective location-based campaigns.

Census-driven insights

The inclusion of Census data within Mesh Blocks, such as the count of usual residents and dwelling types, provides proptech platforms with up-to-date demographic information. This can aid market analysis, customer profiling, and investment strategies.

Integration with digital boundary files

The availability of Mesh Block boundaries in digital boundary files enhances their usability in Proptech applications. These files can be readily integrated into geospatial systems, making it easier for developers and analysts to work with this geographical data.

The foundational building blocks in real estate

Mesh Blocks are foundational building blocks for geospatial and proptech applications, providing granularity and accuracy for understanding local real estate markets, demographics and land use.

To aid proptechs, The Proptech Cloud offers its Geography – Boundaries & Insights dataset which includes all mesh blocks and their spatial areas for analysis and location-based visualisation of statistics.

The integration of this important information can enhance the precision and relevance of analyses within the proptech and real estate sectors. Read our following blog to learn how to incorporate Mesh Blocks into datasets.

Understanding Auction Clearance Rates: Why Do Calculations Differ?

Understanding Auction Clearance Rates: Why Do Calculations Differ?

Auction clearance rates can serve as a barometer of Australia’s real estate market strength, particularly across its major cities.

These rates are generally a superficial gauge of market strength, because private treaty is still the most common means of property sale in some cities. Nevertheless, property predictions can be drawn when auction clearance rates are analysed alongside other factors and data points.

Clearance rates for Australia’s major real estate markets can be helpful for proptechs who leverage data, analytics, and technology to advance various aspects of the real estate industry.

What Is An Auction Clearance Rate?

The auction clearance rate typically represents the percentage of properties that sold on its advertised auction date in a specific market versus the number of properties that didn’t sell during a particular time frame (typically a week or month).

How Are Auction Clearance Rates Calculated?

There are variations in how clearance rates are calculated and reported, so it’s important to consider this and understand your data provider’s calculations. The variance in calculations means these metrics offer different views and are not interchangeable.

 

Variations to the Calculation

Includes properties sold prior to, during and after auctionPercentage of properties sold prior to auction plus on auction date plus after auction date during a particular period (week or month)Sold prior + at + after auction Calculation 

 

What Do Auction Clearance Rates Tell Us?

Auction clearance rates are a crucial market indicator of real estate activity by gauging the numbers of buyers and sellers in a specific market during a certain time frame.

Generally, higher auction clearance rates indicate a higher buyer demand for property in that market, limited supply of available properties and/or with an increased likelihood of rising price, i.e. a hot market for sellers.

Conversely, low auction clearance rates indicates weak buyer demand, possible over-supply of properties and chance of reduced prices which is more favourable to buyers.

In Sydney and Melbourne, a clearance rate above 70% signals a seller’s market, below 60% suggests a buyer’s market, and 60-70% indicates balance.

But the true significance of auction clearance rates lies in its contextual analysis alongside factors such as listing numbers, days on market, withdrawn auctions, fluctuations and regional disparities.

By tracking these rates alongside additional metrics, analysts can anticipate market direction, and measure buyer and seller confidence.

Where Can I Find Clearance Rates For Australia’s Capital Cities?

Auction clearance rates in Australia are reported on a weekly basis.

Some organisations collect data from sales agents and aggregate the data by city and region, such as:

Some news outlets, auction houses and real estate agencies may also publish auction clearance rates for specific regions. Industry reports and analyses related to real estate may also compile this data to provide a comprehensive view into trends.

How Important Are Auction Clearance Rates?

For anyone involved in or impacted by the real estate market, auction clearance rates are an important indicator of demand levels, market sentiment, and potential shifts in property values. But when comparing available data, its crucial to understand the methodology behind the calculations of auction clearance rates.

Auction clearance rates should be used as part of a comprehensive analysis alongside other property data, localised research, and broader market factors. While auction clearance rates offer valuable insights into the direction of the property market, they are just one of many factors to consider, and a holistic approach incorporating various data points is recommended for a thorough understanding of market conditions.

How Might Auction Clearance Rates Be Used By Proptechs?

While not exhaustive, these are a few examples of how auction clearance rates might be used by proptechs and businesses working with real estate data.

  • By analysing clearance rates and buyer demand, price trends can be used to gauge competitiveness of the market. These could all be incorporated into tool development or software development, it could be used to optimise platform features, or to guide content creation to engage users.
  • Combining this information with localised data for property investment, integrating clearance rate data into risk assessment models could allow for more informed investment decisions.
  • Property valuation models could be enhanced with the use of real-time clearance rate data which provides more accurate and dynamic property valuations in areas of high auction activity.

5 Things A Title Search Can Tell You

5 Things A Title Search Can Tell You

When you’re buying or selling property, proving ownership, or refinancing a mortgage, conducting a title search for a Certificate of Title is essential. But what is a Certificate of Title, and what detail can it provide about a property?

A Certificate of Title (sometimes referred to as a title deed or a land title) serves as a public and legal record of land ownership, including interests and restrictions on the land.

In the past, these certificates were physical papers, but with the availability of e-Conveyancing, they are now available electronically.

In Australia, state land registries hold title information. This title information is accessible through a Title Search from an authorised provider in as little as 60 seconds. A title search unveils crucial details, including property owner/s names, land restrictions, mortgage and lease details, and other important information.

Here are five key revelations from a title search:

1. Ownership Details

The Certificate of Title discloses the names of all landowners, specifying the type of ownership—either tenants in common or joint tenants.

This information is vital for understanding the property’s ownership structure and potential implications.

2. Easements

Easements, granting non-owners the right to use land for a specific purpose, are highlighted.

Common easements include drainage, service access and right of way.

Being aware of these easements is crucial as they can impact land use and construction possibilities.

3. Covenants

Covenants, acting as guidelines or restrictions on the land, outline limitations on construction.

Developers create covenants to maintain quality and aesthetics. Understanding these rules is essential for compliance during property alterations.

4. Caveats

Caveats serve as warnings that others have an interest in the property, preventing certain actions like selling.

A caveat is lodged with the state land registry, signaling potential claims to the property.

Buyers must be vigilant for caveats as they indicate potential issues with the property’s title.

5. Mortgages

The presence of a mortgage is disclosed – if one exists – indicating that the bank holds the Certificate of Title instead of the property owner.

This information is crucial for buyers, as the seller must discharge the mortgage before settlement to avoid delays.

Conducting a title search provides a comprehensive understanding of a property’s legal and ownership status, and the careful consideration of these details not only ensures compliance but also helps avoid potential issues, to help individuals, investors or businesses make more informed decisions in real estate transactions.

Understanding Housing Affordability: Key Metrics and Statistics

Understanding Housing Affordability: Key Metrics and Statistics

Housing affordability is a significant concern in many parts of the world, affecting the quality of life and economic wellbeing of individuals and families.

Professor Nicole Gurran from the School of Architecture, Design and Planning says governments around the world are searching for solutions to fix housing affordability, with two opposing schools of thought seeing the solutions as:

  1. Increasing supply. Those in support of this point of view see housing as more expensive because there’s not enough new supply. They see land use regulation and planning processes as restrictive to new construction, adding costly delays and uncertainty to the development process.
  2. On the flipside, others argue that ‘demand side’ factors underlying global house price inflation, such as low cost credit under financial deregulation, or government incentives to encourage property investment are being ignored. They highlight the political influence of property industry groups sustaining housing demand while advocating for reduced regulations. Some even suggest that extensive rezoning reforms may trigger surges in redevelopment and gentrification, potentially displacing individuals with lower incomes.

To truly understand the dynamics of housing affordability we need to take a detailed look at a range of different metrics and statistics to gain a full picture.

Shedding light on these crucial measures can offer insights for homebuyers, policymakers, real estate professionals, and urban planners.

1. Median and Average Home Prices

These figures provide a baseline for understanding the cost of purchasing a home in a particular area, with the median providing a middle point and the average presenting an overall trend.

2. Price-to-Income Ratio

This critical ratio compares home prices to average household incomes. A higher ratio suggests that homes are less affordable relative to income.

3. Housing Affordability Measures

A Housing Affordability Index (HAI) assesses whether a typical family can afford the mortgage on a median-priced home, based on their income. An index above 100 indicates greater affordability.

The issue with the HAI is that it primarily focuses on purchase affordability.

The Australian Institute of Health and Welfare (AIHW) broadens what they classify as housing costs in measuring housing affordability.

AIHW defines housing costs as

the sum of rent payments, rate payments (water and general), and housing–related mortgage payments”,

AIHW expresses housing affordability as

“the ratio of housing costs to gross household income”,

While housing stress is typically described as

lower-income households that spend more than 30% of gross income on housing costs“.

The second measure is a more comprehensive approach which considers a range of housing costs, the complexity of housing affordability and its impact on households.

4. Rent-to-Income Ratio

Rent-to-Income Ratio compares a tenant’s monthly rent to their gross monthly income expressed as a ratio. For those in the rental market, this ratio measures how much of a household’s income is spent on rent, with higher values indicating less affordability.

Rental property

5. Mortgage Interest Rates

Interest rates directly affect the cost of borrowing money for home purchases.

An increase in mortgage interest rates typically mean an increase in mortgage repayments, which can negatively impact affordability.

While a reduction in rates typically means reduced mortgage repayments, which may improve affordability.

6. Mortgage Payment as a Percentage of Income

Mortgage payment as a percentage of income is an important measure of affordability by demonstrating the burden of mortgage payments relative to a household’s income.

This percentage is calculated by dividing monthly mortgage repayments by gross monthly wages. 

The recommended figure is 28% of pre-tax income. Or in other words, no more than 28% of gross monthly income should go towards monthly mortgage repayments.

7. Homeownership Rates

Broad changes in homeownership rates can signal shifts in affordability, and the overall health of the housing market. 

To gain an idea of homeownership rates in Australia, AIHW shares a view of Home ownership and housing tenure in Australia.

8. Cost of Living

Several measures are published to calculate and help gauge changes in the cost of living. Changes in cost of living impacts our household purchasing power and has implications for housing demand. 

The main ways we measure cost of living is the Consumer Price Index.

Consumer Price Index (CPI)

According to the Australian Bureau of Statistics, CPI is a measure of the average change over time in the prices paid by households for a fixed basket of goods and services (which is grouped into 11 categories: Food and non-alcoholic beverages, Alcohol and tobacco, Clothing and footwear, Housing, Furnishings, household equipment and services, Health, Transport, Communication, Recreation and culture, Education, and Insurance and financial services).

 It’s important to note that the calculation of CPI does not include the cost of buying established dwellings, nor mortgage repayments. However, it does include rents, the cost of new dwellings (excluding value of land) and major alterations and additions to dwellings. 

Included in CPI

Not included in CPI

  • Rent
  • Cost of new dwellings (excluding value of land)
  • Major alterations and additions to dwellings
  • Rates and charges
  • Utilities
  • The cost of buying established dwellings
  • The cost of purchasing land
  • Mortgage repayments
  • Costs associated with servicing a mortgage
Consumer Price Index

9. Gini Coefficient of Home Prices

The Gini Coefficient statistical measure is typically used as a measure of income inequality, although it can be used to assess inequality in various other contexts, including home values in a real estate market.

A Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality.

This measure can indicate the inequality in home values within a market, with higher values suggesting greater disparity.

10. Building Permits and Housing Starts

Building permits and housing starts are indicators of building activity and housing supply.  They can signal future market changes which may impact affordability.

11. Vacancy Rates

A vacancy rate is a measure of the percentage of all rental properties that are currently vacant and available for rent.

Fluctuations in vacancy rates can impact rental prices, as elevated rates often correlate with decreased rents, and conversely, lower vacancy rates may lead to higher rental prices.

12. Debt-to-Income Ratio

An individual’s Debt-to-Income Ratio is calculated by taking their total debt and dividing it by their annual income.

This ratio reflects a person’s capacity to afford housing in light of their existing debts.

14. Population Growth and Urbanisation

Rapid population increases or urbanisation can heighten housing demand, affecting affordability.

A Multifaceted View of Housing Affordability

These range of metrics offer a multifaceted and broader view of housing affordability, reflecting the many factors that impact pricing, while implicitly highlighting the complexities of the housing market.

They’re essential for making informed decisions, shaping policies, and understanding market trends.

By keeping a close eye on these indicators, stakeholders can better navigate the challenges and opportunities within the housing sector.

How to Develop a Comprehensive Wildfire Risk Rating for Properties

How to Develop a Comprehensive Wildfire Risk Rating for Properties

The Australian 2019/2020 bushfire season is one of the world’s worst in recent memory. It began in November 2019 in New South Wales and spread across Victoria, Western Australia, South Australia, and the Australian Capital Territory. The extensive fires, fueled by high temperatures and prolonged dry conditions, led to widespread devastation, with a number of lives lost, thousands of homes destroyed or damaged and billions of dollars worth of agricultural damage.

Australia frequently experiences both bushfires and grass fires.

These fires are a natural and integral part of Australia’s environment. Many Australian plants and animals have evolved to not only survive but also benefit from the effects of fire, with some flora depending on fire to assist in its reproduction and growth.

According to Australia State of the Environment 2021, bushfires include all types of fires in the bush – prescribed burns for weed control, cultural burns, fuel reduction burns and wildfires.

Wildfires are bushfires that are out of control, whether they are managed fires that have escaped control or fires that were not deliberately lit.

With the increasing prevalence of bushfires and wildfires globally, assessing the risk they pose to people, properties and infrastructure has become more critical than ever.

Steps to Develop a Wildfire Score Rating

A Wildfire Risk Rating score provides a quantifiable measure of this risk, guiding governments, financial institutions, insurance companies, homeowners, developers and buyers in making informed decisions.

Here we’ll outline a high-level structured approach to developing a comprehensive wildfire risk rating for properties.

1. Defining scoring criteria and scale

Firstly, we establish a scoring scale, typically from 1 (lowest risk) to 5 or 10 (highest risk). It’s important to define clear criteria that contribute to bushfire or wildfire risk, ensuring a comprehensive evaluation.

2. Key factors to consider

Several factors play a pivotal role in determining fire risks:

    • Location and topography

      Proximity to fire-prone areas and the property’s topography can significantly influence risk levels.
      Tools like Archistar have features to determine if your site is in a bushfire-prone zone. With built-in bushfire layers, Archistar can provide accurate and reliable data.

    • Vegetation and landscaping

      The type and maintenance of vegetation around a property are crucial, as some plants are more flammable than others.Australia’s unique geography and climate makes it prone to bushfires. In Australia, hazard reduction burns or prescribed burns are controlled fires undertaken by fire agencies, land managers or by rural landholders to remove vegetation. These are often conducted ahead of the warmer summer months as a means of mitigating the impact of bushfires and reducing fire risks.

      Examples include Forest Fire Management Victoria Reducing Bushfire Risk program and the ACT Government’s Fire Management Policies and Plans aim to reduce the risk of bushfires.

    • Climate and weather patterns

      Weather is a key driver of bushfire ignitions, with a number of factors affecting wildfire activity. Many factors contribute to fire weather, such as a lack of rainfall in the lead-up period, low humidity, strong winds and high temperatures, which all contribute to fire risk on any given day. They can also increase moisture stress on vegetation in the lead-up period.

      Local climate, current and historical weather patterns, including wind conditions and drought frequency, are critical considerations in the development of a Wildfire Risk Rating.

Weather patterns
  • Historical wildfire data

    Historical wildfire data is important because understanding past wildfire occurrences in the area helps predict future risks.
    There is a range of open data sources for historical bushfire data. In Australia, the Australian Government shares a range of bushfire related datasets on data.gov.au and University of NSW shares 100 Years of Bushfire Data.

    This type of data, combined with other data sets conveniently accessible from the one location, the Snowflake Marketplace, can help to develop a fuller picture about historical wildfire in specific areas. For example:

    • Access and infrastructure

      Good access for firefighters and robust utility infrastructure are important for fire response and prevention.

    3. Data collection and analysis

    Gathering relevant data, such as GIS mapping, climate data, and historical fire records, is the next step.

    The Proptech Cloud curates a range of useful datasets available on Snowflake Marketplace to make this process easier.

    Analysing this data allows us to assign a sub-score to each factor based on our scale.

    4. Assigning weights to each factor and calculating the overall score

    Each factor is assigned a weight according to its impact on bushfire risk.

    This step is essential to ensure that more critical factors have a greater influence on the overall score.

    By combining these sub-scores and considering their respective weights, we calculate the property’s overall Wildfire Risk Rating.

    5. Validation and adjustment

    It’s important to validate the scoring system against historical bush and wildfire incidents and expert opinions, adjusting it as necessary for accuracy and reliability.

    6. Regular updates

    As environmental conditions and land use change, it’s important to regularly update the scoring system to maintain its relevance and accuracy.

    The Role of Wildfire Risk Rating

    A well-structured wildfire risk rating is an invaluable tool, helping property stakeholders to understand, assess, and mitigate the risks posed by bushfires. By adopting this methodical approach, we can enhance our preparedness and response to this growing environmental threat.

    Environmental Risks in Real Estate: Essential Metrics for Assessment

    Environmental Risks in Real Estate: Essential Metrics for Assessment

    Driven by greater awareness and demand, environmental considerations are increasingly at the forefront of property development and investment.

    Environmental factors can significantly impact site selection, regulatory compliance, property values, safety, infrastructure, sustainability, insurance costs, and the overall desirability of real estate.

    To adequately build resilient properties for our future, understanding and assessing environmental risks in real estate is crucial.

    Examining the key metrics and statistics used to measure these risks can also provide valuable insights for property stakeholders who are building climate intelligence as a means of value creation and strategic differentiation in the real estate industry.

    On the other hand, the real estate industry contributes approximately 39% of total global emissions. This highlights how factors as broad as the choice of building materials, construction methods, real estate planning and development can influence and help to mitigate global climate change and environmental risk.

    Environmental assessment metrics provide important intel to stakeholders and businesses in and around the real estate industry. 

    Here we examine the top 16 key metrics used in assessing environmental risk in real estate.

    1. Flood Risk Assessment

    Managing flood risk is an important aspect of adapting to global climate change and flood risk assessments have become an important part of risk management practices. The estimation of risk is somewhat challenging and involves careful consideration of a number of varying factors such as location, historical flood data, and elevation.

    Flood risk is a concern, especially for properties near water bodies.

    Flood

    2. Earthquake Risk Score

    In earthquake-prone areas, earthquake risk score is vital. It evaluates the probability of earthquakes and their potential impact, factoring in seismic activity and building standards.

    Earthquake risk metrics can support stakeholders in developing risk reduction measures such as emergency response plans, building design codes, or insurance-related decisions.

    3. Wildfire Risk Rating

    Properties in or near wilderness areas must consider the risk of wildfires. This rating looks at location, vegetation, and climate conditions. There are a number of data and solutions in the market that help decision makers with deeper location intelligence insights, such as CoreLogic with their climate risk solutions and Precisely with their wildfire risk data.

    Then there are those protech innovators who actively incorporate environmental risks into their solutions, such as Nearmap who’ve recently acquired BetterView, will also be integrating risk ratings for data decisions given the ever-changing nature of bush fires, floods, and other disasters.

    4. Storm Surge and Tsunami Risk

    While storm surges and tsunamis are caused by different events, they both have the potential to cause significant harm and damage, such as substantial erosion of beaches and coastal highways, and waves pose a threat to boats and buildings along the shoreline. As the surging waters move inland, rivers and lakes may experience adverse effects, contributing to the escalation of flood levels.

    Coastal properties are evaluated for their vulnerability to storm surge and tsunamis, crucial in today’s changing climate.

    Sea levels

    5. Sea Level Rise Projections

    With climate change, assessing the long-term risk of sea level rise is essential for coastal real estate investments.

    Climate Central’s Coastal Risk Screening Tool is a handy tool for quick future projections.

    6. Air Quality Index (AQI)

    Air pollution stands as the most significant environmental threat to global public health, resulting in an approximate annual total of 7 million premature deaths.

    AQI impacts property desirability and occupant health, making it a significant factor in urban and industrial areas.

    7. Soil Contamination Levels

    Soil contamination can limit property use and affect value, necessitating thorough assessments.

    Australian soil information is collected by government and held by the states and territories. Soil Science Australia, the national soil science body, shares a handy list of Soils Data, Maps and Information Sources for reference.

    Soil

    8. Water Quality Assessments

    Our water systems, including surface and groundwater, catchments, as well as estuarine and marine bodies, constitute intricate ecological networks that we engage with daily. These waterways and wetlands play an important role in:

    • Providing drinking water
    • Supporting irrigation and agriculture
    • Receiving and purifying effluent and stormwater
    • Facilitating recreational and commercial activities such as fishing and boating.

    The quality of local water sources is a key consideration, as it affects usability and desirability

    9. Heat Island Effect

    Urban areas influence the surrounding atmosphere and engage with climate processes, resulting in distinct microclimates within cities.

    This heat island phenomenon leads to urban areas experiencing notably higher temperatures compared to their surroundings, particularly in areas with limited green cover and increased hard surfaces that absorb, retain, and emit heat.

    Urban heat islands can increase energy costs and affect living conditions, and is an important factor in urban planning.

    10. Noise Pollution Levels

    The World Health Organization (WHO) recognises noise pollution—defined as unfavorable noise caused by human activity—as an underestimated threat that can cause a number of short- and long-term health problems.

    As well as contributing to health, noise pollution is often seen as a less-than-desirable attribute contributing to liveability.

    Properties exposed to high noise levels from traffic or industry can affect their value.

    11. Environmental Regulation Compliance

    In Australia, compliance with legislation including protection of threatened plants, animals and ecosystems, wildlife trade, hazardous waste, air quality and monitoring compliance with the conditions of approvals granted under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) is conducted by The Department of Climate Change, Energy, the Environment and Water.

    Compliance with environmental regulations is critical to avoid legal issues and maintain property value.

    Soil erosion

    12. Land Stability and Erosion Rates

    Land stability and erosion rates is affected by soils, surface cover, topography, and climate; all of which are interrelated.

    Particularly in areas with unstable soils or steep terrain, assessing the risk of landslides or erosion is essential for many aspects of real estate such as site selection, development planning and insurance, while these risks can also have an influence on property valuations.

    13. Proximity to Hazardous Facilities

    Numerous research studies have indicated a correlation between living in close proximity to sites with hazardous wastes, industrial facilities, pesticide-treated cropland, busy roadways, nuclear power plants, and gas stations or repair shops, result in an increased likelihood of detrimental health effects.

    Government may form regulations and implement procedures for permits and enforcement to limit pollution.

    As such, properties in close proximity may face increased regulations, risks or insurance costs.

    14. Biodiversity and Wildlife Protection Areas

    With a sustained need for housing, urban planners and conservation managers are consistently exploring alternative strategies for residential development that aim to reduce adverse effects on biodiversity and ecosystem functioning.

    Thus, proximity to protected areas can limit development options and affect property value.

    Biodiversity

    15. Carbon Footprint Analysis

    Climate change is already underway, with an escalating impact that is increasingly affecting all of us around the globe.

    Without immediate and systemic action to address its destructive consequences, the impact is expected to be substantial.

    For greater visibility into the environmental footprint of transactions and impacts of our consumption and production activities, organisations such as FootprintLab provide current, credible and commercially ready carbon data. This information can aid consumers, producers and governments in decision-making that aligns with their sustainability goals.

    Managing carbon emissions from the construction industry is one crucial step in limiting these effects on climate change and a property’s carbon footprint is becoming a significant factor in light of global climate concerns.

    16. Sustainability Certifications

    A green building certification is a verification process ensuring that a building is designed and constructed to enhance energy efficiency, decrease water usage, foster a healthier indoor environment, manage resources and waste effectively, and limit environmental impact.

    The process generally requires adherence to specific guidelines and criteria, often assessed by an accredited third-party organisation, leading to the certification of the building.

    There are different green building certifications around the globe, with LEED in the United States, BREEAM in the United Kingdom and NABERS in Australia, each with its own set of criteria and scoring systems.

    Properties with these certifications are often seen as less risky and more desirable.

    The Proptech Cloud’s Environment and Energy Efficiency Data provides energy supply data and NABERS energy rating data to guide decisions on energy sourcing as part of a robust sustainability strategy.

    Managing Environmental Risks

    Understanding and mitigating environmental risks is important in the real estate sector. By using these metrics, stakeholders can make informed decisions, adapt to environmental challenges, uncover business opportunities and invest in sustainable and resilient properties.

    As the world continues to focus on environmental sustainability, these considerations will become increasingly integral to real estate assessment and development.
