Activate the Structure You’ve Already Paid For
Luxury-level radiant comfort - without added systems or cost.
Structural thermal energy storage that reduces mechanical infrastructure and peak energy demand.
Analyze a ProjectSee How It Works
From Reactive Buildings to Proactive Comfort
Conventional buildings react to temperature swings.
HVAC systems constantly adjust – leading to hot and cold spots, oversized systems, and higher energy demand.
Termobuild makes buildings proactive.
By storing thermal energy in the structure itself, buildings deliver stable, resilient comfort throughout the day – with less mechanical infrastructure, lower capital cost, and reduced peak demand.

Reactive Buildings vs Proactive Buildings
What This Looks Like in a Real Project
675,000 sq.ft K–12 Campus
Deployed across 5 schools using structural thermal energy storage
• ~10% reduction in mechanical capital cost
• 38% reduction in maintenance costs
• EUI reduced to 14–21 (vs ~150 typical)
• Stable radiant comfort throughout the building
Most Buildings Ignore the Energy Already Inside Them
Every modern building already contains thousands of tons of concrete. That structure has enormous thermal capacity - but in most buildings it does nothing.
Termobuild activates the building structure itself as thermal energy storage. Most conventional buildings are reactive - HVAC systems constantly react to temperature swings - leading to hot and cold spots and occupant complaints.
By storing thermal energy in the structure itself, Termobuild makes buildings PROACTIVE, delivering stable and resilient comfort throughout the building.

Why Structural Thermal Storage Changes Building Economics
Through integrated HVAC and rechargeable floor design, concrete floors and ceilings become thermal energy storage systems – delivering:
- $10-$30 per sq.ft. lower up-front capital costs
- Up to 75% lower daytime HVAC energy demand
- Stable radiant comfort with fresh air ventilation
- Long-term operating savings
No changes to your specification guide
Results based on modeled and operational performance from Termobuild projects across multiple building types and climates.
Proven Performance
• Canada’s two most efficient schools
• 678,000 sq ft net-positive development in South Carolina
• 18+ years operational performance
What This Means
• No exotic equipment
• No complex mechanical systems
• No new technology risk
• No changes to your specification guide
Simply a smarter use of the building structure.
Proven integration. Lower risk. Better outcomes.
The Result
Buildings that are:
• More comfortable
• More energy efficient
• Less expensive to build
• Simpler to operate
• Thermally stable instead of reactive buildings
All by activating what the building already contains.
The Future of Buildings Is Energy Storage
Structural thermal storage lets buildings store energy when it is cheapest and deliver comfort when it is needed.
- Electrification is increasing peak loads
- Grid constraints and peak demand are increasing
- Mechanical infrastructure costs continue rising
- Traditional HVAC designs increase peak demand
- Structural thermal storage reduces peak loads and simplifies systems while improving indoor comfort.
With over 18 years of experience in education, healthcare, commercial, residential, and civic buildings. These projects demonstrate how activating the building structure can deliver superior comfort while reducing capital costs and energy demand.
Where Termobuild Works Best
- Universities and campuses
- Hospitals and healthcare
- Commercial buildings
- Luxury residential
- High-performance buildings
- Energy-constrained developments
Termobuild works with project teams early in design to deliver better buildings at lower cost.
By activating the structure as thermal energy storage, buildings shift from reactive HVAC control to proactive thermal stability - reducing cost, improving performance, and increasing long-term value.How We Work With Project Teams
A straightforward way to partner with us and elevate your building project outcomes.
Project Evaluation
The first step is a review of your new building design or retrofit project. We start with mechanical design brief and architectural plans - to determine if our integration is a strong fit.
Cost-Benefit Analysis
Next, we conduct a cost and performance analysis so your team can evaluate the financial and operational impact before designs are finalized.
Mechanical Strategy
Finally, our engineering team works closely with your project team from planning through construction to seamlessly integrate the system into your architectural design and mechanical strategy.
Backed by a globally insured guarantee
Structural thermal storage stores energy when it is cheapest while delivering luxury-level radiant comfort and fresh air ventilation throughout the building.
Request a Project Cost-Benefit Analysis
Both new construction and retrofit projects may benefit from structural thermal energy storage integration.
We’ll review your building design to determine whether Termobuild can reduce capital cost and peak energy demand.
