Not a Lab Box. A Full-Scale Room.

Across our published papers and research, we refer to this facility as the TESTCELL. It's more than a simulation room. It's a calibrated, full-scale instrument for in-situ testing of innovative product prototypes.

The vision of our TESTCELL is to examine how products behave under the full spectrum of renewable energy generated, consumed, and the ultimate comfort level, all accomplished in the room in accordance with international standards.

This north-facing facility replicates the thermal behaviour of a real occupied space. A 7.5 m² glass wall, walls insulated to Australian standard, and high-standard instrumentation throughout.

Measured Against the International Benchmarks

ASHRAE Standard 55

Thermal Environmental Conditions for Human Occupancy. The comfort benchmark used globally for building system evaluation.

ISO 7730

Ergonomics of the thermal environment. PMV, PPD, and draft risk metrics applied across sampled occupant positions.

Real-World Scenarios

Heating, cooling, and mixed-mode tests across a range of outdoor conditions, not just a steady-state chamber.

High-Standard Measurement Across Every Run

From thermal comfort carts to heat flux sensors, every channel is logged continuously for full-run analysis.

ISO 7730 thermal comfort cart

Thermal Comfort Carts

2× ISO 7730 / ASHRAE-55 compliant carts measuring PMV, PPD, operative temperature, and draft risk.

Thermal imaging camera on tripod

Thermal Imaging Camera

Thermal imaging results displayed on monitor

Live Results Display

Real-time visualisation of thermal data during a test run for rapid iteration.

Heat flux sensor

Heat Flux Sensors

Hukseflux FHF-series sensors measuring heat transfer through assemblies and panel surfaces.

Thermocouple array

Thermocouple Arrays

Distributed air-temperature measurement across vertical and horizontal planes.

Campbell Scientific data logger

Data Logger

Campbell Scientific CR10X continuously logs every sensor channel for full-run analysis.

On-site weather station

Weather Station

On-site monitoring of outdoor conditions: ambient temperature, humidity, solar radiation, wind.

The Environmental Service Pod

The TESTCELL is powered entirely by our own Environmental Service Pod (ESP), run on renewable (solar PV) energy. The ESP is a modular, prefabricated unit that consolidates every energy service into one system.

  • Battery / inverter storage and conversion
  • Polyvalent heat pump for simultaneous heating and cooling
  • Thermal storage tanks (hot and cold)
  • Hydronic Operations Distribution Module (HODM)

Renewable Energy → Hydronic Conditioning & Hot Water

One closed loop: solar generation, heat-pump conversion, thermal storage, distribution, delivery.

From Baseline to Performance Report

1

Baseline measurement

We characterise the room's thermal behaviour without any conditioning system active. This is the reference signature every test is measured against.

2

System installation

The product under test is installed exactly as it would be in a real building. No lab shortcuts.

3

Controlled scenarios

Heating, cooling, and mixed-mode tests run across a range of outdoor conditions to capture real performance.

4

Continuous data collection

Every sensor channel logs continuously: comfort metrics, energy consumption, and system response times.

5

Analysis, reporting & continuous improvement

Results are compiled into a performance report with recommendations you can act on. Every test also feeds back into EES R&D, so we learn from each run and refine our own products.

Current & Future Research

Currently in test: our modular hydronic ceiling panel innovation. The first system of its kind designed for standard Australian ceiling grids.

Coming next:

  • Dynamic facade systems
  • Shading product testing
  • Comparative testing: conventional split-system vs. radiant hydronic conditioning

A Real Room Built for Real Testing

The TESTCELL is a full-scale, instrumented room constructed inside the workshop. It's not a sealed laboratory chamber. It's built to behave like a real occupied space, with solar gain through glass, ventilation, and thermal mass. That's the point: we test under the same conditions our products will face in the field.

Every element was designed and constructed in-house: steel framing, insulation, glazing, ceiling grid, plumbing, and instrumentation. The room is aligned to ASHRAE-55 and ISO 7730 testing standards.

How We Built the TESTCELL

From steel studs to a fully instrumented simulation room. Every element was designed and constructed in-house.

Steel stud framing of the TESTCELL structure inside the EES workshop

Steel Frame Construction

The room was framed from steel studs to Australian Standard specifications. A permanent structure with proper wall and ceiling framing, not a temporary enclosure.

Envelope and Membrane

Building wrap membrane applied over the full structure. The room sits inside the larger workshop but is thermally isolated from it. It behaves as an independent building envelope for testing purposes.

Glazing and Insulation

A 7.5 m² commercial-grade double-glazed window was installed on the north face to simulate worst-case solar gain. R2.0 batt insulation throughout all walls. The window is the most thermally challenging element in any real building, so we built around one.

Hydronic ceiling panels installed in the suspended grid Installer fitting a hydronic ceiling panel into the suspended grid inside the TESTCELL

Ceiling Panel Installation

Hydronic ceiling panels were installed into the standard 600 × 1200 mm suspended ceiling grid. The ceiling is divided into bays, each fitted with a different architectural finish, allowing direct comparison of surface performance under identical conditions.

Plumbing and Hydraulics

PPR (polypropylene) piping with brass fittings connects each panel to the central manifold. A system-wide flow meter provides feedback control across the entire circuit. The hydraulic system runs on 24 V DC for safety.

Completed and Commissioned

The finished TESTCELL: a fully enclosed, instrumented room with timber flooring, finished walls, suspended ceiling, and full environmental monitoring. Hydraulic equipment and water storage sit immediately outside the room for short pipe runs and minimal thermal losses.

Built, Tested, Iterated.

Alongside the TESTCELL, our in-house workshop fabricates the panels and components required for each experiment, enabling rapid iteration from prototype to tested product.
