Webinar on development of an IoT-based smart window by integrating a solar PV blind and ventilation system

The BD Division and our co-organisers, the Hong Kong Institute of Construction Managers (HKICM) and The Hong Kong Institute of Surveyors Quantity Surveying Division (HKIS-QSD), were pleased and honoured to have Dr Minhyun Lee deliver a webinar presentation via Zoom on a research project to develop Internet of Things (IoT)-based multi-function smart windows for zero energy buildings (ZEB) on 23 July 2021.

Dr Lee, an Assistant Professor in the Department of Building and Real Estate (BRE) at the Hong Kong Polytechnic University, specialises in smart and sustainable building management. Dr Lee conducted a research in a multi-function smart window as a combination of PV blinds and ventilation system.

Her research was conducted in different phases using seven prototypes, starting from the development of a simple solar PV blind to an integrated film solar PV blind with natural or mechanical ventilation systems, and eventually to an loT-based multi-function smart window using a mono-Si solar PV blind and hybrid ventilation system.

In addition, software was developed to monitor and control the smart window in real time based on the NI LabVIEW software  programme. By using automatic control technology for both the solar PV blind and the ventilation system, the smart window could maximise solar PV blind electricity generation and optimise indoor air quality.

The design of smart windows, to a certain extent, can address the energy consumption problem in the building sector and improve the quality of the air in indoor environments. It is expected that the smart window could be widely applied in building to help realise ZEB in the future.

We would like to thank Dr Lee for her fruitful and informative presentation, and her great contribution to innovation in energy saving.
