A Digital Twin (DT) refers to a digital replica of a physical entity which holds a dynamic copy of the physical entity's state. With the rise of energy consumption in the built environment, it becomes an urgent matter to improve energy efficiency in buildings. DT has the potential to improve energy efficiency in a building. It can not only aid in optimizing energy usage in a building, but also act as a platform for testing building control systems. Current development of DT mainly focus on the field of smart manufacturing and product design and less on the building level. This paper presents a framework to create a digital twin for indoor environments for the purpose of occupants' satisfaction and energy efficiency. The initial experiment result builds a foundation in future DT development with a digital-physical heat loss comparison. The limitations, challenges, and future direction in creating DTs for the built environment are also addressed.
