During 2019-2020, Our team joined an R&D program, “Smart Ublo; Ventilation Sensor Phase 1”, as the Didimdol Startup Growth Project, granted by the Ministry of SMEs and Startups in South Korea. It was for calculating the capacity of buoyancy ventilation with a ublo window and developing its IoT sensor to find occupants’ comfort zones by natural ventilation.

There was another opportunity to have joint research with Yonsei University on “Zero energy building package engineering advanced track”, which reinforced the experiment by comparing the numeric values from CFD simulation and on-site experiment data.

Ventilation sensor development scenario

1. Calibration of Hugo Sensor based on valid data
2. Optimized positions of sensors inside Ublo
3. Locating Mesh sensors to find valid data for occupants
4. Building ventilation map with a Ublo window

Sensor concept: when do we open & close operable window for ventilation?

Preliminary research for gauging the UBLO’s ventilation performance

Phase 1 -1
The performance of this study was to compare the buoyancy ventilation performance of Ublo windows. Its flow equations with finite methods were realized with Solidworks flow simulation, done by Christophe Szukala at VS-A HK.

Phase 1-2
Comparing the buoyancy ventilation of ublo with the general casement window. The CFD model was callibrated by the actual values as a part of joint research program with Yonsei University.
