GBCSA launches custom pilot rating tool for industrial properties

The Green Building Council South Africa (GBCSA) has launched a new Green Star - Existing Building Performance (EBP) Custom Industrial pilot rating tool, now available for all industrial properties to use.

Industrial buildings form a notable portion of South Africa’s existing building stock. Better-managed and better-performing green industrial buildings have great potential to decrease energy and water consumption, as well as reduce waste-to-landfill production. Furthermore, warehousing and distribution centre types of buildings often have the capacity, because of their roof-space-to-energy-use ratio for solar panels, to generate more energy than the building demands, enabling them to be exporters of energy.

“Industrial buildings, such as warehouses, manufacturing plants, and logistics facilities, play a key role in the smooth running of national and regional economies. It’s vital that these assets are future-proofed for the impacts of a changing climate and the rising costs of energy, water, waste, and emissions, as well as delivering a range of other benefits for their tenants,” explains Errol Taylor, head of asset management: industrial at Growthpoint - sponsors of the new tool.

Rewarding sustainably managed buildings

The GBCSA’s existing Green Star EBP tool is aimed at rewarding buildings that are managed sustainably well, can demonstrate good operational performance over a measured period, and that contribute towards better quality spaces for tenants. “When the original EBP tool was developed, it endeavoured to take as many building typologies as possible into account, but there were nonetheless limitations and, in reality, it has largely been applied to the commercial office segment of the market,” explains GBCSA head of technical, Georgina Smit.

The customisation process was adopted to ensure that GBCSA can offer the market standardised guidelines for energy and water benchmarking of industrial buildings, as this currently does not exist in the South African property market. Furthermore, nuances around industrial building ownership needed to be slightly reconsidered within the tool to better serve the market.

For example, many single tenancies operate on triple net leases which places a lot of the operational decision-making with the tenant and not the landlord. “A custom tool is not a new one, but instead focuses on customising the existing tool for a new typology to better suit the functionality and user profile of that typology,” explains Smit.

What’s different about the new EBP Custom Industrial pilot tool?

The Custom Industrial pilot rating tool follows the same structure as the current Green Star – EBP v1 tool but with clarifications and benchmarks specific to the industrial sector. Some specific differences property owners can expect to see are:

  • Credits that are better aligned with the varied kinds of industrial building typologies. With respect to energy and water, benchmarks have been put forward for specific sub-categories such as distribution centres, warehousing, light manufacturing, and workshops. All energy and water usage is included within the benchmarking process, with certain conditions set out for the exclusion of unusually large process loads.

  • A new Energy and Water Benchmark Framework that can be used when following benchmarking operational performance for the industrial sub-categories. This has been developed from a dataset collected specifically from existing industrial buildings and will perform the function of providing a simplified industry benchmark, but one that has taken some normalising factors into account. Existing operational performance data was contributed by major REITS, analysed by the appointed sustainability consultants, and new benchmarking parameters were set to form this framework.

    “The significance is that it will tangibly support industry by offering a standardised methodology for analysing energy and water performance data both for comparisons (that is, to compare apples with apples) as well as in offering indicative benchmarks based on primary data that has been collected,” adds Smit.

  • Credits that support property owners and tenants working together at improving assets. As with the EBP v1 tool, property owners are able to address some credits without necessarily involving tenants. However, for many of the credits relating to building management practices such as waste management, green cleaning, and so on, it will be necessary to have the tenant commit to implementing such procedures.

Taylor anticipates that over time the new tool will demonstrate that Green Star – EBP Custom Industrial certified buildings outperform non-certified industrial buildings against ESG criteria and financial returns on investment.

Smit concludes: “GBCSA hopes to support the market transformation of the industrial sector in the same way it supported the journey of the commercial office space with this tool. We are also hoping to embark on a journey of continuous energy and water data collection in order to refine benchmarks for future iterations of the EBP tool.”
