The Green Building Council South Africa (GBCSA), together with rating tool sponsor Nedbank Corporate Property Finance,  announced the development of the new Green Star SA Existing Building Performance rating tool in September 2013, – addressing demand from an entirely new segment of the property market in South Africa.

The new rating tool will allow effective and objective measurement of an existing building’s environmental performance in operation. It will assess key performance indicators (KPIs) relevant to specific environmental issues, such as energy and water consumption.

“This is a powerful tool, giving property owners the chance to make every building a greener building, thus leveraging the benefits such as  lower operating costs, higher returns on assets and increased property values,” says Frank Berkeley, Managing Executive: Nedbank Corporate Property Finance.

To date, the GBCSA’s efforts have focused on new buildings – advocating specific design and technical interventions to be implemented before and during construction to improve environmental impact and performance.

“It is a natural progression of the rating tools currently at our disposal, and unlocks a whole new frontier for the GBCSA,” says GBCSA CEO Brian Wilkinson. Because new buildings only account for about 1-2% of a company’s property portfolio, the Existing Building Performance rating tool is a game changer – allowing all property owners to embrace environmental sustainability across their entire building stock,” adds Wilkinson.

This new rating tool signals the GBCSA’s shifting focus to include transformation of the existing building stock in South Africa, where a critical mass can be leveraged and make a substantial difference in the impact of the built environment on the natural environment.

Identify, Manage, Improve
“The Existing Building Performance tool focuses firstly on understanding the issues, and then managing existing buildings more efficiently and sustainably. It will allow building owners to analyse and benchmark their property portfolio, set out plans for improving the performance of their building stock, and create a common language recognising the value of high performing buildings which can be communicated to both tenants and investors,” explains GBCSA project manager Francois Retief.

The credits of the rating tool will fall within three broad categories, and will consider:  measurable performance indicators such as water, energy and waste management, lease agreements, management contracts or procurement policies that define performance requirements and building attributes that inform performance.

Specific design solutions on how to achieve KPI’s will not be prescribed, but links to other resources and education in this regard will be given. The rating tool will also provide resources to ensure that the building’s environmental performance can be maintained or improved upon over time.

The Green Star SA Existing Building Performance rating tool can be applied to a number of different building typologies, such as offices, retail establishments, industrial buildings, hotels and public buildings and hospitals.
The Green Star SA – Existing Building Performance rating tool will profile and highlight buildings that are being well operated, and ensure that they stand apart from those which are doing more damage than good.

Streamlined process
Significant stakeholder engagement through the International Property Databank (IPD), showed that the South African market wanted a performance rating tool to be accessible and simple; for certification to be viable within operational budgets; and for building tenants to see the value of certification.

As such, a streamlined online certification process will be used for the first time within the GBCSA. Through simplicity and minimising documentation, the cost of certification is also reduced. Aspirational value will also be maintained and aligned with the current Green Star SA brand, and 4, 5 and 6 Star certifications will still represent SA Best Practice, SA Excellence and World Leadership respectively.

“The streamlined process allows large volumes of existing buildings to start on the Existing Building Performance journey, showing incremental improvements in their buildings as they work toward higher star ratings,” explains Retief.

Environmental imperative
Assessment and improvement of South Africa’s existing building assets is a necessity, just as responsible and green building of the country’s future building stock is vital to improve the built environment’s impact on the planet.

Globally the built environment is responsible for about 40% of the world’s energy consumption, and generates one third of global carbon dioxide emissions – thus this sector presents the single largest, and most cost-effective opportunity to tackle climate change, and limit natural resource depletion.

“It is incredibly humbling to see the level of interest and support from the industry in the development of this rating tool. It truly is a rating tool developed for the market by the market,” adds Retief.

“Nedbank Corporate Property Finance is extensively involved in financing new Green Star Rated buildings, and as financiers and occupiers of green buildings, we look forward to the value that this new rating tool will add to the journey of a more a sustainable environment,” concludes Berkeley.
