The Energy & Environment Expo 2014 (17th–19th June 2014, ExCeL London) addresses the challenges of sustainable energy supply and usage. Visitors to the EnOcean Alliance stand M1645 can experience batteryless wireless sensor solutions that help to monitor and to reduce energy consumption in buildings.
The technology uses an energy harvesting principle that enables sensors, switches and actuators to operate without batteries. This offers high installation flexibility and comprehensive monitoring with minimal maintenance required. On the stand, Pressac Communications and EnOcean will highlight their latest product developments. EnOcean will present energy harvesting wireless components, alongside demonstrations of the Pressac Sensing range of energy monitoring devices from Pressac Communications.
Batteryless wireless systems that monitor and control energy efficiency in buildings can detect potential energy savings and reduce consumption on a large scale. This is achieved via energy harvesting wireless technology from EnOcean, which powers communications by collecting energy from the surroundings such as motion, indoor light and temperature differentials. Due to this, the products do not need batteries or maintenance while offering flexibility in system planning and implementation.
EnOcean technology achieves international standard ISO/IEC 14543-3-10. The EnOcean Alliance has more than 350 member companies worldwide, developing and promoting products and systems based on the EnOcean standard. Promoters build the organisation’s highest membership class. In this role, companies like Pressac and EnOcean lead, define and drive the Alliance as innovative key players.
Highlights at the EnOcean Alliance stand M1645 include:
Pressac Communications will be exhibiting a broad range of its new Pressac Sensing energy monitoring solutions. For electricity measuring purposes the company offers the patent pending wireless current transducer (CT) clamp. The clamp doesn’t require batteries, wiring or interruption to the power supply and can simply be clipped around any AC cable to measure the current flowing in a single mains conductor. Using this product, energy or facility managers can understand the operational costs of each appliance on a daily basis. The CT clamp is suitable for plant energy monitoring, energy reduction targeting, sub metering or HVAC optimisation.
For air quality monitoring within buildings, the range includes a CO2, temperature and humidity sensor. This fully wireless, solar-powered room sensor is powered by ambient light from the surrounding environment and allows fast and easy installation with minimal disruption for retrofits.
An IP-based gateway provides connectivity between IP-based networks and EnOcean-based wireless devices. Users can monitor and control EnOcean networks from IP servers and devices in real-time and bi-directionally. This is a cost-effective enabler to integrate building/plant processes with enterprise software and to enhance a system’s intelligence including remote monitoring and control.
The Pressac sensing dashboard is a web-based analytics platform that provides energy usage alerting and reporting. It delivers a simple way to identify inefficiencies and diagnose issues within buildings. The dashboard is cloud-based, so there is no software to install, and its appearance can be individually configured to suit the users’ specific requirements. Also, Pressac Sensing will preview three new products at one exhibition: a mini temperature and humidity sensor, a relay switch and a pulse counter.
EnOcean GmbH will present its complete range of energy harvesting wireless solutions. The comprehensive platform includes energy converters, ultra-low power radio, wireless modules, energy management and software. Based on the technology, a wide range of self-powered applications is available, including batteryless switches, intelligent window handles, temperature, humidity and light sensors, as well as occupancy sensors and heating valves. These products act as the sensory organs, “the eyes and ears” of a building, supplying the necessary information for energy-efficient control.
