The property sector is under increasing pressure to deliver on sustainability. Rising energy costs, stricter regulations and growing tenant expectations mean that greener buildings are no longer optional, they’re essential. Technology is at the heart of this transformation, helping owners and investors cut emissions, reduce costs and enhance asset value. Here’s how:
Smart building management systems
Modern building management systems (BMS) integrate heating, ventilation, air conditioning, lighting and power into one intelligent platform. These systems monitor and adjust operations in real time, responding to occupancy and external conditions. Studies show BMS can cut energy use by up to 30% through optimisation and predictive maintenance.
IoT sensors and data analytics
IoT sensors track energy consumption, occupancy and environmental conditions. Combined with analytics, this data helps identify inefficiencies and optimise performance. This supports ESG compliance and reduces waste.
Energy-efficient upgrades
LED lighting with smart controls: LEDs use up to 90% less energy than traditional bulbs.
AI-controlled HVAC: AI-driven systems can reduce HVAC energy use by 8–19%.
Renewable energy integration: Solar panels and heat pumps lower reliance on fossil fuels and cut carbon emissions.
Digital twin and simulation technology
Digital twins create a dynamic, data-driven replica of a building that mirrors real-world conditions in real time. This allows owners to test scenarios before committing to physical changes.
For example, you can simulate the impact of adding solar panels on energy consumption and carbon output, helping you forecast savings and validate ROI before installation.
Green building certifications
Tech-enabled buildings are better positioned for certifications like BREEAM, LEED and WELL, which validate sustainability practices and enhance asset value.
Automation and centralised IT
Automated workflows streamline maintenance and lease administration, reducing labour and energy costs. Centralised IT unifies disconnected systems, such as access control, HVAC and lighting for greater efficiency.
AI and machine learning
AI analyses large datasets to forecast energy demand and recommend retrofits. This enables smarter investment decisions and maximises ROI while reducing environmental impact.
Sustainable construction and circular economy
Sustainability starts with how buildings are designed and built. Digital tools enable low-carbon materials, modular construction and design for reuse, reducing embodied carbon and waste.
Optimising logistics is equally important. CACI’s work with major retailers shows that advanced route planning and transport management can cut supply chain emissions by up to 25%, helping construction projects lower costs and support circular economy goals.
Real-world impact
Smart buildings can reduce energy costs by up to 40% through integrated management systems.
Examples include The Edge in Amsterdam, which generates more energy than it consumes, and The Crystal in London, which achieved BREEAM Outstanding and LEED Platinum certifications.
