Thermal Mass vs Active Structural Energy Storage

How Termobuild Turns Concrete into Energy Infrastructure

Concrete has long been valued for its thermal mass – the natural ability of heavy materials such as concrete to absorb and release heat slowly.

Termobuild builds on this principle by activating the structure as part of the building’s energy system, allowing energy to be intentionally stored and delivered when needed.

Passive Thermal Mass vs Active Structural Energy Storage

Concrete Does More Than React.

Concrete has long been valued for its thermal mass. Termobuild builds on that principle by enabling the structure to function as an actively managed energy storage system.

While both rely on the thermal storage capacity of concrete, passive thermal mass reacts to environmental conditions, while Termobuild actively manages the structure as part of the building’s energy system.

Thermal mass moderates temperature. Termobuild makes buildings proactive.

The Evolution of Thermal Mass

Passive thermal mass was an early strategy for improving building performance.

Termobuild evolves this concept by turning the structure into active building energy infrastructure.

Benefits include:

• lower peak loads
• simplified HVAC systems
• stable radiant comfort
• consistent performance across climates
