TLDR
In this paper, an IoT end-to-end system was developed to collect relative humidity (RH), CO 2 concentration and occupant count of a University classroom, and the RH and CO 2 data has been used to compute estimates of student occupancy using regression based estimation models.Abstract:
An IoT end to end system has been developed in this work to collect relative humidity (RH), CO 2 concentration and occupant count of a University classroom. The RH and CO 2 data has been used to compute estimates of student occupancy using regression based estimation models. Multiple linear and quantile regression models have been explored for occupancy estimation by using RH, CO 2 , and both RH as well as CO 2 concentration respectively. The estimation performance of these models has been compared by using mean absolute percentage error. The quantile regression based models have been found to be the most accurate with a mean absolute percentage error of 2.47%.read more

Importance of occupancy information for building climate control
TL;DR: In this paper, the authors investigated the potential of using occupancy information to realize a more energy efficient building climate control, focusing on Swiss office buildings equipped with Integrated Room Automation (IRA), i.e. the integrated control of Heating, Ventilation, Air Conditioning (HVAC) as well as lighting and blind positioning of a building zone or room.
