The Green Star Rating System and its value to business

What is the green star rating system?

The Green Star Rating tool system is a certification from the Green Building Council of Australia (GBCA) that has been designed to help promote sustainable practices in the building industry and operational sustainability in built environments. Importantly, GBCA’s internationally recognised rating system is not solely focused on sustainable construction, although how a building is constructed has specific categories in the Green Star Rating system.

The rating system has a strong commitment to the ongoing management and operation of sustainable buildings. This is important when considering the impact the built environment has on carbon emissions, and the effect of the operation of the built environment on the health of people.

Why do we need sustainability in our built environments?

According to studies into building sustainability, the ongoing operation of the global built environment contributed to 27% of global emissions.  This figure is even higher than the emissions from the construction industry of new buildings (20%). 

Additionally, there have been countless studies on the negative impact of the office environment on workers who spend long hours inside corporate buildings.

It’s no wonder that corporate sustainability is fast becoming a key element to a businesses’ sustainability credentials.  Greening, energy conservation and sustainability has been promoted in residential housing for more than a decade, and now house buyers highly value sustainable homes.

It’s not difficult to imagine that this shift will happen in our corporate worlds.  Already there are headlines where employees and customers are demanding more of a focus on sustainability.  This expectation from stakeholders has led to greenwashing, where the corporate world is promoting its sustainability credentials. 

The demand for sustainability and a lack of accountability for sustainability has given rise to programs such as the Green Star Rating system.  It provides guidelines which are independently verified before someone can earn the rating.

Green Star Ratings and corporate sustainability

The Green Star Certification is a certification that has arisen out of a demand from customers and employees of businesses to become more environmentally responsible. But what does that mean?

GBCA has created four categories to assess the environmental performances of the built environment in the corporate world. These four categories of Green Star certified buildings are;

Green Star – Communities

The trend for development companies across Australia is to build city-style large projects that are built with development rules or covenants for residential builders, and/or have multi-use developments. A developer will often include retail space, commercial/office space, community space, and facilities such as schools, childcare, and even hospitals as part of a development.

GBCA recognised this trend in development and the importance of having broad sustainability guidelines, so created a category for sustainable building or community project design.

Green Star Buildings – Design and As Built

This category is targeting the construction industry, which makes up more than 20% of global emissions. It’s at the design and construction stage that the greatest leaps in sustainability can be made in our built environment. GBCA recognised this by creating this category. However, new buildings make up only about 2% of total built environments each year. That’s why the following two categories are so important in promoting corporate sustainability.

Green Star – Interiors

This category and its related Green Star Rating Tools are for new fit outs. The recommendations and regulations of this category aim for businesses to develop sustainable space for workers in confined office and commercial spaces through interior design and internal construction.

The GBCA’s Green Star category for such internal fit-outs has identified that there are a handful of benefits that arise when you achieve a Green Star Rating. These benefits include productivity gains (higher return on investment, attracts tenants, time and resource efficiency and environmental benefits) and sustainable reputation gains (market recognition).

Green Star – Performance

This category is the most relevant for commercial spaces looking to develop more sustainable practices through its operations, including adding green space. The Green Star Rating system provides guidelines and pathways for existing buildings to incorporate sustainability practices in their operations.

There are nine key criteria assessing the sustainability of operations. These criteria are management, energy efficiency, transport, water, materials (construction and demolition waste management), land use and ecology, emissions, innovation, and indoor environment quality.

Creating green space helps to meet the criteria of indoor environment quality, because green space in communal areas and on desks improves workers psychological well-being, air quality, and reduces noise. The natural feel also helps to create a calm atmosphere.

According to GBCA, including indoor environment quality in the Green Star voluntary sustainability rating system improves an occupant’s experience of the space and contributes to their wellbeing. It also helps to deliver a better company image. A recent study into the top things a company can do to make employee’s lifestyles sustainable was to green rooftops and create vertical gardens in the office.

How does earning a Green Star Rating help your business?

A Green Star Rating is more than just an opportunity for a company to greenwash its operations, because the rating system is independently assessed, and the criteria is based on sustainability fundamentals.

Earning a Green Star Rating can offer some significant benefits to businesses. The first is giving a business the reputation as socially responsible. The second is employees’ expectations are changing and value working in an environment that embraces a healthy lifestyle, and they want to work for companies that value sustainability and are socially responsible.

Recent surveys of office workers across Asia and the Pacific has revealed that more than 50% of workers would prefer to work for a company that valued and operated using sustainability principles.

Promoting your sustainability credential through the Green Star Rating system will help to attract workers, and is important when vying for workers in a competitive labour market.

Increase your company’s appeal by creating green space

As we have discussed, promoting sustainability can benefit your business – but it’s worth revisiting why creating green space is valuable.

To sum it up, green space in an office will give direct and immediate benefits to your built environment. It improves air quality, helps reduce noise in the office, and promotes the psychological wellbeing of your workers. The GBCA has recognised this value by making it an important indicator of corporate responsibility.
