The British Council for Offices (BCO) is piloting a new grading framework, moving away from the outdated “Grade A” badge. Offices will now be scored across four tiers: Prime (≥80 points), Grade A (50–79), Grade B (30–49), and Grade C (<30).
BCO chief executive, Samantha McClary, says: “As demand for high-performing, sustainable and amenity-rich workplaces continues to grow, the industry needs a shared language to distinguish truly exceptional space. The proposed framework supports the market’s flight to quality and provides clarity for investors, developers and tenants alike. It’s about creating offices that deliver long-term value – for people, for performance and for the planet.”
The Redefining the Market: Beyond Grade A report found that Sustainability is now central and that 96.5% of respondents rated sustainability certifications (e.g. EPC, BREEAM, NABERS) as essential to office quality – more than any other factor.
That’s where CSR Sustain is helping lead the way. Through our AI-powered HVAC optimisation platform, we are already supporting landmark assets such as Exchange Quay in Manchester cutting energy waste, lowering carbon, and improving occupier comfort.
And it’s not just BCO grades at stake. Achieving strong NABERS Energy in-Use ratings also relies on HVAC optimisation. The reality is that design standards alone can’t close the performance gap - only continuous, data-driven operational improvements can. Moving beyond NABERS Design for Performance to real-world optimisation is critical for any building aiming to prove its sustainability credentials in use.
The benefits are clear:
Lower energy costs and emissions through real-time optimisation of HVAC systems
Healthier workplaces with improved comfort and air quality
Predictive maintenance that reduces downtime and avoids unnecessary spend
Future-proof assets aligned to both BCO and NABERS Energy standards
With both BCO scoring and NABERS in-use ratings raising the bar, AI-driven HVAC is no longer just a smart upgrade. For offices targeting Prime, Grade A, or high NABERS stars, it’s becoming essential to close the gap between aspiration and performance.
