According to the Department of Energy,
HVAC systems are responsible for about 40% of the total
energy consumption. Increasing the energy efficiency of
these systems can radically reduce the energy
consumption. This paper aims to compare two case
studies using different automated HVAC systems in terms
of their energy efficiencies.
Previously, HVAC systems were manually operated
and monitored which made it quite tedious and
inefficient. In the recent decades, integrating HVAC
systems with IOT has turned out to be quite effective and
efficient. Building automation systems and Building
energy management systems are two such systems which
use smart sensing networks.
This paper analyses two case studies based on the
different energy efficiency measures and performance of
the automated HVAC systems. Further it discusses the
importance of automation in increasing the energy
efficiency, facilitates easy maintenance and makes the
system cost effective.
