Surface collection
SECTA treats selected external surfaces as low-temperature thermal collectors, gathering available energy from solar gain, ambient conditions, rainfall effects and the near-surface ground environment.
SECTA is an engineering-led approach to harvesting low-grade thermal energy from external surfaces and making it useful through controlled accumulation, hydraulic separation and water-to-water heat pump integration.
A finished surface can become part of a wider engineered energy system — but only when the design, controls and responsibility boundaries are properly defined.
SECTA has been developed for projects where the external surface is already important — a driveway, courtyard, pathway, public realm, service area, podium, car park or specialist resin-bound finish — and where that same surface could quietly do more.
SECTA treats selected external surfaces as low-temperature thermal collectors, gathering available energy from solar gain, ambient conditions, rainfall effects and the near-surface ground environment.
The collected energy is not left to chance. A Ground Array Accumulator provides a controlled interface between the surface collector and the building-side energy system.
SECTA is not a resin surfacing trick. It is a coordinated system philosophy involving hydraulic design, controls logic, heat pump integration and commissioning discipline.
We do not ask surfacing contractors to become heating engineers — and we do not ask heating engineers to guess the surfacing.
SECTA sits at the interface, where the clever work normally gets lost between trades.
The difference is not simply the pipe beneath the surface. The difference is the design responsibility around it.
SECTA is intended for architects, landscape designers, developers, local authorities, resin-bound surfacing specialists and M&E professionals who want to explore whether an external surface can become part of a credible heating and cooling energy strategy.
SECTA has been shaped from long-standing HVAC, hydronic and heat pump design experience, with a practical understanding of what happens when an attractive concept meets real groundworks, real plantrooms and real commissioning.
The result is a surface energy approach that respects traditional engineering basics: flow, temperature difference, controls, heat transfer, access, responsibility and maintainability.
New idea, old-fashioned discipline. That combination tends to keep the wheels attached.
Use the surface that is already being built. Collect what the environment offers. Accumulate it sensibly. Then integrate it through competent HVAC design rather than marketing optimism.
The best time to consider SECTA is before the external surface design, drainage strategy, plantroom concept and heat pump approach are fixed. Early advice costs less than late excavation — a truth known to every engineer with muddy boots.
