Thank you for walking together through Hong Kong Green Week and World Green Building Week 🌍💚 

“If we walk alone, we walk fast; if we walk together, we walk far.” 

At AEC Group, we choose to walk together with our clients and partners turning ambition into measurable outcomes. Hong Kong Green Week and World Green Building Week amplified the call for climate action – from green finance to the built environment.  

Why it matters: 
• Buildings drive ~37% of global CO₂ and ~one third of global energy use – the built environment is a powerful climate lever. 
• Embodied carbon can be ~50% of a project’s total emissions – the “hidden” carbon from making, transporting and constructing materials.  Please reuse and low carbon materials are essential. 
• Around half of the buildings that will stand in 2050 are not yet built especially in fast growing regions – that means what we retrofit today and design tomorrow will lock in outcomes for decades. 
• Smart upgrades can cut building energy intensity by up to 38% (≈ 12% lower global energy demand) and reduce staff sickness by ~20–30% when health focused (IEQ) measures are included. 
• Everyday behavior helps too: as we shared on our LinkedIn, wearing breathable, loose fitting fabrics keeps people comfortable at higher AC setpoints like ~25.5 °C – and each +1 °C can save ~3% AC electricity in typical office conditions.
