Thank you the Society of Operations Engineers (Hong Kong Region) (SOEHK), for inviting us to collaborate on a webinar with us. Felix Chan and Faris Lui were the speakers sharing on “Towards Smart City decarbonization empowered by digital technologies”. We were thrilled to receive an overwhelming response from the audience. We are welcome to cooperate events and webinars related to smart building, ESG, decarbonization or any other topics related to energy saving with different associations and societies to promote future building to the public.
