Research in energy-efficient buildings is a burgeoning field, which has led to increased use of sensors in building applications. Green building construction has become easier with the advent of smart sensors and actuators, as information on local environment and occupancy enables building automation systems to utilize energy in an efficient manner.
New analysis from Frost & Sullivan, Sensors for Energy Efficient Buildings and Building Management, finds that sensors are gradually becoming an integral part of buildings, allowing the demand-based control of systems such as lighting, heating, ventilation, and air conditioning. Equipping buildings with motion and air quality sensors too has become a popular trend in the construction sector in recent times.
The integration of wireless communication techniques in sensors has helped overcome the challenges posed by wired sensor networks.
Incorporating energy harvesting techniques in sensors will ensure that zero power is drawn from the electricity grid while also reducing maintenance by eliminating the need for battery replacements. Sensor errors such as not being able to detect human presence or indicating the presence of an occupant even when no person is present can limit widespread implementation.
Multi-sensing capabilities for various parameters such as temperature, humidity, carbon dioxide levels, and light intensity along with occupancy sensing will facilitate comprehensive monitoring of the environment and minimize sensor reading errors to a large extent, the report says.
