The hotel sector demonstrates how quickly this dynamic can reshape investment patterns. NABERS hotel ratings jumped 40 per cent in 2024/25, driven by government procurement policies, consumer awareness through booking platforms, and investor requirements all aligning. Hotels appeared in the Sustainable Portfolios Index for the first time, with CapitaLand and the Schwartz Family Company bringing around 6,000 rooms into measured performance reporting alongside traditional office and retail.
What makes the hotel story particularly interesting is the consumer-facing visibility. NABERS ratings now display on Google Travel with an "eco-certified" tag and are recognised by Travalyst's global platform. This puts performance data directly in front of millions of travellers making booking decisions. When sustainability credentials start influencing occupancy rates, they are influencing asset valuations and measurement moves from a reporting exercise to something that affects revenue.
The Sustainable Portfolios Index expanded to 67 portfolios across 30 companies covering over 500 assets. New indicators tracking renewable energy and electrification show some portfolios achieving close to 100 per cent renewable energy and 99 per cent electrification. Three shopping centre portfolios reached full carbon neutral coverage, with this level of transparency setting performance benchmarks that influence where institutional capital flows.
The integration of NABERS into Australia's sustainable finance framework addresses a practical challenge, demonstrating that the substantial capital required to upgrade thousands of buildings to meet net zero commitments is being deployed effectively. High NABERS ratings provide verified evidence of actual performance rather than projected targets, giving investors and lenders confidence that sustainability claims can be measured.
Buildings covered by the Commercial Building Disclosure programme have improved their energy intensity by 29 per cent over twelve years, demonstrating that measurement drives improvement. With the CBD expansion roadmap released in October 2024 broadening these requirements, NABERS ratings are increasingly functioning as both compliance evidence and competitive advantage.
What this means for owners and buyers of commercial property
For owners holding assets with weak or no NABERS credentials, access to capital is becoming more conditional on verified performance. The gap is widening between buildings that qualify for green finance and those that don't, which has implications for both holding costs and exit strategies.
For buyers, buildings with strong NABERS ratings provide financing advantages that extend beyond the purchase. As lenders and investors align with the Sustainable Finance Taxonomy, assets that meet the criteria will have access to capital pools that others won't, affecting acquisition feasibility today and disposal options in the future.
For developers, building to high NABERS specifications ensures the asset will be financeable and marketable as government mandates expand and investor requirements tighten. The hotel sector's 40 per cent ratings surge demonstrates how quickly policy requirements, consumer preference, and capital availability can align to make performance measurement essential.
The pattern from 2025 is clear, performance measurement has moved from a reporting requirement to a determinant of asset value. Whether driven by procurement policies, consumer-facing platforms, or finance framework criteria, NABERS ratings have become the standardised measure that determines access to capital. In a market where financing increasingly requires verified credentials, measurement has become the link between sustainability performance and the ability to finance, hold, and transact commercial property.
