Abstract

The traditional way to control energy systems is by strategies based on principles of physics. Now there is a transformation where the decision-making is driven by information and data technologies. In this talk, we will briefly review some data-driven applications. With an increasing number of applications, a new challenge is to support such applications at scale. The main problem is how to handle various levels of heterogeneities in different building energy systems so that data and machine learning models can be automatically handled by a platform with minimal human involvement. We present our recent works to automatically translate data into standards and extract data under various local data conventions; as well as schemes to evaluate appropriate machine learning models at scale. We are working with the Electrical and Mechanical Services Department (EMSD) of the Hong Kong government to benchmark data and machine learning models, in the hope to accelerate AI deployment in the campaign towards a smart city and a green city.
