Meeting Room Assistant Joan is the greenest meeting room scheduling solution available, with energy consumption so low, it supports a battery life of several months. Installed in meeting rooms around the world, Joan uses 99 percent less power than other room scheduling solutions, and is easily attachable on all surfaces, even glass. Joan displays room availability, announces upcoming events and allows for spontaneous meetings booked at the door.

Running on Visionect’s electronic paper driving board, the device features a 6-inch E Ink interactive electronic paper display, which uses electricity only when the content on it is changing. This makes Joan extremely energy efficient and completely independent from the power grid. In fact, the device can boast a battery life of several months on a single charge. Because of this, the E Ink label requires no cabling and is easily attached on any surface via the enclosed magnetic strip.

Most digital door labels are an exercise in energy consumption with displays that need to be charged daily or require constant access to the power grid. The never-ending energy drain makes implementing a room scheduling gadget heavy on a company’s budget. In fact, different office equipment is reported to be the fastest growing energy user in the business world—its consumption representing 15 percent of total electricity use in offices, with the figure expected to double by 2020.

Even when implemented, energy-heavy door labels can require significant construction works when installing the device wiring, which often makes mounting hard if not impossible on certain surfaces. D.Labs, an app developer company, was just one of the companies faced with this issue. Their glass meeting rooms could not successfully support the cabling necessary to sustain an electronic door label.

Unlike other room scheduling labels, Joan features an E Ink display, with a 180-degree viewing angle, paper-like readability and no glare or light pollution. E-paper doesn’t consume electricity when static, making the power consumption of Joan’s touchscreen zero when not actively used.

As a consequence, Joan is able to run for several months on a single battery charge, which eliminates the need for wires or cables supplying power to the device. This never-before-seen energy efficiency means that Joan can be easily attached to any surface, even glass or wood, via a magnetic stick-on strip located at the back of the device, without the need for heavy drilling.

Joan also supports additional energy-saving settings, such as setting office hours, outside of which the device is in hibernation mode. When not being used, Joan’s screen is turned off, but the information displayed always remains clearly visible.

For D.Labs, as well as other companies, implementing Joan brings the option of a room scheduling device that is easily fixable on glass, wood, brick or concrete alike. No drilling is necessary. The device is charged once every few months, showing room availability and allowing for booking on the spot or via online calendars already in use.

Even more, because Joan’s technological features enable minimal power consumption, 99 percent less than that of comparable room booking solutions, using Joan results in extreme energy savings. Put in context, if 55 million conference rooms worldwide were equipped with iPad minis for room booking, this would result in about 110 Megawatts of constant energy consumption. Energy-saving Joan would reduce this consumption by 99 percent, leaving enough power to provide lighting for 2 million average households and saving approximately $100 million USD in electricity bills each year.

Visionect was nominated for a DSE 2016 APEX Award in the Business & Government Services category.
