YomaBouw is an innovative company building with future-proof biobased products such as hempcrete. We delivered a plug-and-play sensor network and data-analysis service to support their research efforts.

The problem

YomaBouw is researching to what extent street furniture made of hempcrete cools its environment. Quantifying this effect requires precise, continuous measurement across a real-world test location — without disrupting the research setup.

Scope · GCSC

We designed and delivered a sensor network at their test location, capturing temperature, humidity, and environmental conditions at the resolution needed to characterise the cooling effect of hempcrete. Alongside the hardware we provided a data-analysis solution so the research team could extract meaningful conclusions directly from the measurements.

Building on the control architecture developed in Phase 1, GCSC and VenFeld are advancing the VirtuHot solar-thermal platform from a validated prototype to a market-ready MVP — hardening the hardware, refining the software, and preparing the system for commercial deployment.

From Phase 1

Phase 1 established the full-stack control architecture: custom PCBs integrating industrial protocols, a closed-loop controller, and an operator-facing interface. Phase 2 picks up where that foundation left off, stress-testing it against real-world conditions and closing the gap to a shippable product.

Scope · GCSC

Maturing the embedded hardware and software stack into a robust, manufacturable product: improving reliability, tightening tolerances, and delivering the integration work needed to bring VirtuHot to its first commercial installations.

Supported by the Kansen voor West 3 programme and co-financed by the European Union, alongside commercial investment.

GCSC and VenFeld are developing the control hardware and software for the VirtuHot solar-thermal system: a platform engineered to raise thermal efficiency, cut CO2 emissions, and ease pressure on the electrical grid.

Scope · GCSC

Five custom PCBs integrating industrial protocols and mixed signal types, running a closed-loop controller alongside an operator-facing interface.

System synergy

VirtuHot collectors charge a thermal buffer that feeds the source side of a water-to-water heat pump. A warmer source raises the COP, so the same heat output costs less electricity — compounding two benefits: lower CO2 emissions and flatter peak loads that reduce grid-congestion risk.

Full-stack delivery

  • System architecture: unified logic binding collectors, storage, and heat pumps into one coordinated plant.
  • Custom hardware: IoT-capable PCBs handling PWM, analog, Modbus, and SPI on a single board.
  • Embedded software: low-level firmware and protocol stacks tuned for reliability, speed, and robustness.
  • Advanced controls: feedback loops and real-time optimisation driving continuous efficiency gains.

GCSC is developing Soma, a smart climate control platform that makes existing heating installations efficient without renovation or upfront investment, delivered as a single subscription covering hardware, installation, software, and service.

The problem

SMEs, schools, and healthcare organisations in ageing utility buildings are falling behind on sustainability. Classical retrofits are technically feasible but blocked by high CAPEX, disruptive construction, and lack of service, so buildings responsible for roughly 14% of Dutch CO2 emissions stay stuck on inefficient heating.

Scope · GCSC

A plug and play control layer, combining wireless sensors, smart radiator valves, and a boiler gateway on a Zigbee hub, driven by a predictive algorithm that uses weather, occupancy, and building thermodynamics to hold every room inside its comfort band at minimum energy.

Full stack delivery

  • Smart hardware: Zigbee sensors, smart radiator valves, and CV gateway installed directly on existing radiators and boilers, with no rewiring and no downtime.
  • Predictive control: an optimisation algorithm combining weather forecasts, occupancy, and building dynamics, heating only when and where it's needed.
  • Cloud monitoring: remote tuning, real time energy and CO2 dashboards for facility managers.
  • Subscription delivery: installation, software, and maintenance bundled. CAPEX becomes OPEX, savings start day one.
  • Validated impact: targeted 20 to 30% reduction in heating energy use without comfort loss.

GCSC is developing Griddle, an edge native monitoring system that gives distribution operators real time insight into the low voltage grid: the layer where solar, EVs, and heat pumps connect, and where most operators today are blind.

The problem

Low voltage grids were never designed for two way power flows. With rapid connections of solar, EV chargers, and heat pumps, operators lack visibility below the MV/LV transformer and fall back on worst case assumptions when planning reinforcement.

Scope · GCSC

Custom sensing hardware paired with an edge inference stack running a physics informed neural network state estimator, enforcing Kirchhoff's laws on device, without cloud dependency for critical calculations.

Full stack delivery

  • Sensing hardware: Rogowski coils and voltage probes, sampling at 8 kSps with capture up to the 80th harmonic.
  • Edge compute: on device inference, with critical calculations running without cloud dependency.
  • State estimation: physics informed neural network enforcing Kirchhoff voltage and current laws.
  • Grid integration: IEEE 1588 PTP time sync (±1 µs), IEC 61850 MMS + GOOSE output, 4G/LTE connectivity.
  • Dynamic envelopes: real time Dynamic Operating Envelope computation and sub Hz oscillation detection (0.2 to 1 Hz).
