For architects and design teams

Design more value into the building.

Rechargeable concrete floors. Radiant comfort. Less mechanical demand. A stronger financial case.

Same structure. Different strategy. Termobuild integrates ductwork into rechargeable cast-in-place or hollow-core concrete floors. Building controls are shown with a built-in thermal energy storage algorithm and a separate control-signal connection to HVAC. The concrete stores heating or cooling energy ahead of demand. Diffusers deliver conditioned air into the occupied space, and the concrete supports radiant comfort. Illustrative curves compare conventional HVAC demand with load shifting. Project-dependent outcomes: up to 75 percent less daytime energy use and 38 to 50 percent potential HVAC capacity reduction.

A better starting conversation

Bring the opportunity into the room early.

The architect can help connect design intent, the mechanical strategy and the owner’s investment.

Before systems are sized, ask what the concrete floor can contribute to comfort and load management. Termobuild uses integrated ductwork and active controls to store heating or cooling in the concrete ahead of demand.

That gives the project team another design path to evaluate: one where the building itself carries part of the thermal load.

Evaluate it while floor, ventilation and mechanical decisions can still be coordinated.

Make it relevant to your project

Three conversations worth having before systems are sized.

Can comfort stay in the design through budget review?

Evaluate radiant comfort and fresh-air delivery alongside the mechanical scope and capital budget. Put the occupant experience into the same discussion as the owner’s economics.

How much of the load can the floor carry?

Ask the engineering team to compare a conventional approach with active concrete thermal storage. Project modeling can inform potential changes in HVAC capacity, energy timing and operating costs.

What should we coordinate now?

Bring the floor system, air routes, diffusers, ceiling strategy and controls into early coordination. Their relationship matters to both the architecture and the engineering.

Performance belongs in the experience of the space.

The University of Windsor project connects this conversation to a completed architectural setting. Termobuild features it as an example of radiant comfort and fresh-air ventilation.

Use the animation to explain the mechanism. Use the built space to discuss what matters to the people inside.

Project fit + coordination

Start with the floor. Coordinate the rest.

Cast-in-place and hollow-core concrete floors can be evaluated. Fit depends on the building, floor configuration, occupancy, climate and mechanical strategy.

  • Cast-in-place concrete
  • Hollow-core concrete
  • New construction and selected retrofits

Questions to bring to the team

Architecture
Comfort goals, occupancy, spatial priorities and the ceiling strategy.
Structure
Floor configuration, duct integration, openings and penetrations.
MEP + controls
Ventilation, air connections, load modeling, equipment selection and the operating sequence.
Termobuild
Thermal storage assessment, modeling and integration support alongside the project team.

Conventional HVAC systems remain part of the strategy. Equipment selection and specifications stay with the project’s mechanical engineer.

A practical next step

Bring a project. Start a useful comparison.

Early drawings and mechanical design criteria give the discussion a concrete starting point.

  1. Share what is taking shape.

    Bring the building type, location, design stage and preliminary architectural drawings. Identify the floor approach and the owner’s priorities.

  2. Compare the opportunity.

    Review the potential effects on HVAC capacity, capital cost, peak demand and long-term operation against the project’s design criteria.

  3. Coordinate the next decisions.

    Use the initial assessment to decide what warrants further development with the owner, architect, structural engineer and MEP team.

Before you bring it to the team

A few practical questions.

The right conversation starts with your project’s actual design conditions.

When should we introduce Termobuild?

During early design, while floor, ventilation and mechanical strategies can still be considered together. An initial evaluation is most useful before mechanical capacity and related scope are finalized.

Is this limited to hollow-core or cooling?

The approach can be evaluated with both cast-in-place and hollow-core concrete, for heating and cooling. Floor configuration and operating conditions determine the project-specific integration.

Does this require a proprietary HVAC package?

The approach integrates with conventional HVAC. Your engineering team retains equipment selection; Termobuild supports the thermal storage modeling, controls strategy and coordination.

What should we bring to an initial review?

Architectural drawings and mechanical design criteria, together with the project location, design stage and key owner priorities. The initial review can identify opportunities and questions for further engineering evaluation.
