Seven 3-axis Gill R3-50 sonic anemometers, measuring three-component wind velocity and direction, were deployed: two within the cube itself and five outside. The two sonic anemometers closest to the instrumented cube and two internal sonic anemometers were mounted on masts, with the centre of the sonic anemometer at 3.5 m above ground level (in line with the opening centre). The Channel mast sonic anemometer was at 2.9 m (maximum height for the equipment) and logged at 20 Hz. All others were logged simultaneously at 10 Hz to a MOXA UC 7410 Plus fan-less compact computer.  


The cube surface pressure was measured using pressure taps: 7 mm holes located centrally on 0.6 m2 steel panels, which were mounted flush onto the cube cladding. Pressure signals were transmitted pneumatically, using 6 mm internal diameter plastic tubes to transducers within the cube. The individual transducers meant that the pressure tap measurements were simultaneous at 10 Hz. The pressure differential sensors for pressure taps 1-16 were Honeywell 163PC01D75 differential pressure sensors with a range of -2.5 to 2.5 inches of H2O (~-498-498 Pa). Pressure taps 17-32 were Honeywell 163PC01D76 differential pressure sensors with a range of -5 to 5 inches of H2O (~-1245- 1245 Pa). All pressure sensors had a manufacturer stated response time of 1 ms.


30 external pressure taps and 2 internal pressure taps were used. The internal pressure measurements were located under the openings. The 30 external pressure taps used were split across the four faces, four on the roof, four in a horizontal array on the centre line across the North and South faces and nine on the front and back faces, with five of those in a vertical array down the centre and four in a horizontal array at half building height.

Temperature measurements inside the cube allowed determination of thermal stratification, and along with the external temperatures, the thermally-driven ventilation component. External temperature was measured on the Channel mast using a Vaisala WXT520 weather station (manufacturer�s stated error at an air temperature of 20 °C = ± 0.3 °C), which was positioned to minimise solar gains. Internal temperatures were measured at 24 points at 10 Hz using RS components K-type 1/0.2 mm diameter thermocouples (measurement range -75 °C to 250 °C). Sampling at 10 Hz allowed for the average to be taken of a large number of samples, leading to a reasonably accurate mean half-hourly value.

Eight thermocouples were horizontally strung between the windows at a height of 3 m. The other 16 were in four vertical profiles of four thermocouples, put at varying heights and limited in height to being below 4 m due to access limitations. The size of the thermocouple errors (0.45 % ± 2 °C, junction plus thermocouple) are unsuitable for measuring instantaneous fluctuations in temperature (Kaimal and Finnigan, 1993).
