Abstract

Productivity of workers is greatly affected by their comfort in the workplace. Research has shown that thermal comfort is one of the most influential parameters on worker productivity, and that the running costs of a Heating, Ventilation and Air Conditioning (HVAC) system could be up to ten times lower compared to productivity losses that would be incurred in a free-runing building. With the increased availability of Internet of Things (IoT) devices, it is now possible to continuously monitor multiple variables that influence a user’s thermal comfort and to act pre-emptively to prevent discomfort situations. Smart buildings make use of technology that enable them to become more efficient, reduce costs and emissions and become more transparent in terms of operation. To this end, this work has the following aims; develop a machine learning model to predict setpoint temperatures in an HVAC system; use exploratory data analysis techniques to evaluate the current operation and energy performance of an HVAC system in an office block; and finally, identify and compare patterns and trends between BMS parameters and thermal comfort standards.
