Solutions
Reducing complexity, impacting where it matters
REAL RESULTS
HVAC REVOLUTION
Buildings waste energy every day trying to guess what cooling they’ll need. GRAM changes that.
Advanced Machine Learning
Understands airside and waterside characteristics to enable intelligent control.
Intelligent Loads Synchronisation
Continuously aligns cooling load with chiller efficiency in real time, adapting quickly to all tenants’ needs.
Smart Equipment Diagnosis
Detects real-time airside responsiveness which supports timely maintenance.
Fast, Non-Intrusive Deployment
Integrates directly with BMS; no extra sensors, no disruption to tenants.
Developed at NTU and co-founded by its inventor, GRAM Tech is a smart software that combines machine learning with real-time optimisation to automate HVAC control tailored to each building’s behaviour.. At GRAM, we believe that data-driven insights are key to achieving efficiency. GRAM Tech doesn’t just respond to static conditions; it continuously learns from data and adjusts based on real-time environmental and operational needs, ensuring that every building’s cooling system operates optimally at all times.
Although GRAM Tech only influences the airside, its intelligent adjustments result in reduced energy consumption on both the airside and waterside—without the need for hardware retrofits or IoT sensors. This makes deployment easier and more scalable across different types of buildings. Our software dynamically adjusts airside setpoints based on real-time demand, allowing every tenant to enjoy their own ambient comfort, while also improving energy efficiency.
Innovation is at the core of GRAM Tech, enabling us to continuously evolve and refine our solutions to meet the demands of modern buildings. While we’re focused on cutting-edge, adaptive technology, we also place a strong emphasis on trust and transparency. By relying on real-time, reliable insights, we empower building operators to make informed decisions, ensuring that energy use is optimized without compromise.
Unlike off-the-shelf solutions, our close connection to the technology means we can adapt it quickly to different building systems and operational needs. No additional sensors. No hardware retrofits. Just better results. Tested in various environments, GRAM Tech has achieved up to 20% HVAC energy savings—while keeping tenants comfortable and operations teams in control.
By reducing unnecessary cooling, we help buildings cut energy waste and lower their carbon footprint—contributing to more sustainable, climate-ready cities.
