Real-time monitoring of occupancy activities and window opening within buildings using an integrated deep learning-based approach for reducing energy demand (2021)
Journal Article
Tien, P. W., Wei, S., Calautit, J. K., Darkwa, J., & Wood, C. (2022). Real-time monitoring of occupancy activities and window opening within buildings using an integrated deep learning-based approach for reducing energy demand. Applied Energy, 308, Article 118336. https://doi.org/10.1016/j.apenergy.2021.118336

Occupancy behaviour in buildings can impact the energy performance and operation of heating, ventilation and air-conditioning (HVAC) systems. HVAC, which uses conventional control strategies or “fixed” setpoint schedules, could not adjust to the cond...

Performance evaluation of combined solar chimney and radiative cooling ventilation (2021)
Journal Article
Suhendri, S., Hu, M., Su, Y., Darkwa, J., & Riffat, S. (2022). Performance evaluation of combined solar chimney and radiative cooling ventilation. Building and Environment, 209, Article 108686. https://doi.org/10.1016/j.buildenv.2021.108686

Passive cooling is inevitable for buildings to be resilient to global warming. While many forms of passive cooling techniques have been developed, passive radiative cooling (RC), as an emerging technology, is still not widely applied in buildings. Du...

The impact of thermal insulation on cooling energy consumption and optimal insulation thickness for underground tunnel (2021)
Journal Article
Wang, Y., Wang, C., Gao, S., Zheng, X., & Darkwa, J. (2021). The impact of thermal insulation on cooling energy consumption and optimal insulation thickness for underground tunnel. Sustainable Energy Technologies and Assessments, 47, Article 101495. https://doi.org/10.1016/j.seta.2021.101495

The provision of mechanical cooling in deep mines comes with a significant energy cost as a significant amount of heat transfers from surrounding rock to the airflow. Thermal insulation can be applied to reduce such heat transfer, thereby cutting dow...
