Analyze a ProjectSee How It Works

Most modern buildings lack radiant comfort and high levels of fresh air ventilation because the systems required are too expensive.
Termobuild makes luxury-level radiant comfort possible – while lowering capital and energy costs.

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.

Termobuild makes buildings proactive.

Charge the Structure

Off-peak air conditions the concrete structure when energy is cheapest.

Store Thermal Energy

The structure becomes a massive thermal battery.

Release Stored Energy

Stored heating and cooling energy is released slowly throughout the day - reducing HVAC demand while delivering stable radiant comfort across the building.

Termobuild works with owners, architects, and engineers early in the design processhelps project teams deliver better buildings at lower cost. The result is a building that performs better financially and operationally for decades.

We help teams increase project profit and NOI, accelerate construction timelines, and deliver smarter healthier spaces. By activating the structure as thermal energy storage, buildings shift from reactive HVAC control to proactive thermal stability.

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.

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.
