Zodhya is proud to have become a global pioneer in the ATOM (Adaptive Thermal Optimisation and Mapping) approach.

Why do we need ATOM?

A building’s heating and cooling needs are constantly changing. They fluctuate throughout the day based on factors like weather, solar gain, occupancy, equipment loads, and HVAC performance. Yet many facilities still rely on outdated systems that assume everything is steady. This is where the problem begins.

Our research shows that approximately 60–70% of energy consumption in commercial buildings is used for heating and cooling, making it one of the largest sources of energy demand in the built environment. Despite this, traditional HVAC systems continue to rely on static setpoints and fixed schedules (powered by their automation/ control/ BMS systems), which don’t adjust to the real-time needs of the building.

Such scenarios are leading to the following consequences that include:

• Over-conditioning of spaces
• Peak-time discomfort
• Wasted energy
• Higher operational costs
• Increased wear on HVAC equipment

There’s energy and money to be saved!

And there’s a way to solve this, and it’s much smarter than relying on existing static settings.

The ATOM Approach: A Smarter Way to Optimise Energy

The ATOM approach uses advanced mapping to capture a facility’s real-time thermal behaviour. By integrating local weather data, indoor conditions, and HVAC system performance, the SaverX platform precisely calculates the heating and cooling loads required at every moment.

According to ASHRAE, systems that incorporate adaptive control can achieve 25–30% better energy efficiency than traditional systems that rely on static control methods (ASHRAE Guideline 14, 2019). Our platform, SaverX, automates this process by continuously adjusting HVAC settings based on real-time thermal conditions. This adaptive, closed-loop control replaces outdated static setpoints and schedules with data-driven decisions, ensuring optimal performance throughout the day.

How ATOM helps you operate HVAC better

Here’s what you can expect when you implement the ATOM approach via the SaverX solution:

Reduce operating expenses: By eliminating chronic over-conditioning of spaces, we ensure HVAC systems aren’t overused, saving both energy and money.

Stable comfort: Thanks to real-time adjustments, comfort levels are maintained consistently across all building zones, no matter the time of day.

Extend HVAC equipment life: ASHRAE recommends maintaining proper system load management to avoid unnecessary stress on HVAC components, which can extend system lifespans and reduce repair costs (ASHRAE Standard 90.1, 2016).

Easy, transparent performance tracking: Real-time metrics, aligned with IPMVP (International Performance Measurement and Verification Protocol) and ASHRAE guidelines, provide clear insights into energy use and system performance, making it easier to track savings and improvements.

Why ATOM Makes Sense

The ATOM approach works because it is based on the principle that buildings are dynamic. Real-time thermal mapping, combined with adaptive optimisation, ensures that only the energy needed is used at the right time. This not only reduces energy waste but also helps facilities operate more sustainably, avoiding the costly inefficiencies of traditional systems.

ASHRAE reports that adaptive systems, such as SaverX, that use real-time data can achieve up to 30% more energy efficiency compared to static systems (ASHRAE Guideline 14, 2019), which speaks volumes about the power of real-time adjustments.

The ATOM Benefits in Action

Here’s how ATOM has benefited different industries:

Office Buildings (Chennai, India):

• Annual savings: 78,861 kWh
• Energy cost reduction: 25%
• Emissions reduced: 56,780 kg CO₂/month

Airports (Hyderabad, India):

• Annual savings: 126,000 kWh
• Energy cost reduction: 15%
• Emissions reduced: 90,720 kg CO₂/month

IT Facilities (Tokyo, Japan):

• Annual savings: 17,200 kWh
• Energy cost reduction: 14%
• Emissions reduced: 10,519 kg CO₂/month

These results highlight the proven effectiveness of the ATOM approach in reducing energy consumption while ensuring occupant comfort.
