People’s interaction with the indoor environment plays a significant role in energy consumption in
buildings. Mismatching and delaying occupants’ feedback on the indoor environment to the building
energy management system is the major barrier to the efficient energy management of buildings.
There is an increasing trend towards the application of digital technology to support control systems
in order to achieve energy efficiency in buildings. This article introduces a holistic, integrated, building
energy management model called ‘smart sensor, optimum decision and intelligent control’ (SMODIC).
The model takes into account occupants’ responses to the indoor environments in the control system.
The model of optimal decision-making based on multiple criteria of indoor environments has been
integrated into the whole system. The SMODIC model combines information technology and people-
centric concepts to achieve energy savings in buildings.

Humankind is confronted by great threats from                   However, energy consumption in buildings is
climate change and energy famine. Recent                        strongly related to occupants’ satisfaction and their
energy consumption figures show that buildings                  behaviour when using energy to improve their
