secure

how Coris works

Each Coris Gateway module can support up to 35 ICTs. Once your Gateway is connected to a router with an Ethernet cable, it automatically connects to Coris' secure servers in the cloud. The ICTs are then able to communicate with the servers.

Whether you have rooftop air conditioners or package units, your existing thermostats can be replaced with Coris Internet-Controlled Thermostats (ICTs).

Once installed, Coris' encrypted wireless mesh network enables ICTs to communicate with one another to reach a Gateway module.

a few features

schedule DR events online, in advance

As soon as the ICTs are communicating with the servers, you can view their status and setup Demand Response event schedules via the web-based Coris interface. Here is an example of a one-hour curtailment test at a New York City office building using Coris' Automated Demand Response (ADR) controls.

The scheduling interface is very intuitive—once you're satisfied with the schedule you've defined for one day, you can apply it to multiple days quickly.

DR curtailment schedules can be activated with the click of a button. At the end of the DR event, normal HVAC schedules will resume. The ability to setup HVAC schedules and monitor system performance becomes a powerful tool for energy efficiency throughout the year.

graphs and downloadable data for analysis

graph of ICT settings and temperature readings

This is our customers' favorite ICT graph, available on the Coris web-based interface. For each ICT, you can view this for any time period you choose. As you hover over different times on the graph, a dot appears on each data set represented, and the values at those times are shown in the upper right corner of the graph.

easy horizontal zoom function of y-axis

If you want to see more detail along the y-axis, simply highlight an area to zoom-in.

easy vertical zoom function of x-axis

If you want to see more detail along the x-axis, simply highlight an area to zoom-in—same as y-axis zooming.

thermostat names and organization

Similar to how file folders work on a PC, Coris Folders make it easy to organize large numbers of devices by location with simple “drag-and-drop” operation.

Coris Folders can contain all the devices in a particular department or all the devices in a particular location. There is no limit to the number of folders and subfolders you can use—allowing sophisticated organization by schemes such as by country, by region, by city, by building, by floor, by restaurant, etc.

sub-accounts allow you to delegate controls and access

For institutions with large numbers of installed Coris modules, access to the logged data can be limited based by assigning sub-accounts. These sub-accounts exist within an overarching user account, but only have access to those folders and devices that the main user deems appropriate.

"The Coris system performed extremely well, and this bodes well for our other ADR ventures."

Coris in action

Large Restaurant

A large restaurant with banquet areas installed Coris thermostats to control the large air conditioning units in the restaurant. Since most DR events were scheduled from 1pm to 5pm, the restaurant pre-chilled the dining areas on the mornings of an event (they were notified the night before of an upcoming event); they use the Coris controls to turn the A/C units off at 1pm, but keep fans running. Lunch usually lasts until 2pm, so the dining areas remain comfortable. With the A/C turned back on at 5pm, the dining areas were comfortable for dinner.

Golf Course

A golf course installed Coris thermostats and Coris water pump controls to participate in DR events. Similar to the restaurant mentioned at left, the dining and active member areas are pre-chilled before DR events, but the bar area is left alone because it includes an informal dining area and is occupied most afternoons. The large pumps that move water between ponds (reservoirs for sprinkler systems) are turned off during DR events.

Office Building

The owner of a 450K-square-foot office building wanted to participate in the local utility’s demand response program. Their electrical usage usually peaked at 1,500KW during warm summer days. The demand response aggregator worked with the owner to determine the amount of load that could be shed without causing discomfort for tenants or operational problems. A goal of 500KW to be shed during DR events was agreed upon, and Coris HVAC controls were installed to manage the load shedding. During the testing and validation, Coris provided support to the building owner’s staff, and they were able to exceed the goal. They have successfully exceeded their goals for all DR events since installation.

FAQs

Is there a limit to load that can be controlled by Coris?

No, any number of air conditioning units, lights, pumps, or other high-wattage devices can be controlled through the Coris web-based control interface.

Can I remotely control multiple facilities with Coris modules?

Yes, there is no limit to the number of facilities or locations that can be controlled through Coris' web-based control interface.

Can I prevent tenants from changing settings?

Yes, the thermostats can be "locked out" during DR events—prohibiting manual adjustments to individual thermostats.

Can I pre-chill the building prior to a DR event?

Yes, many buildings pre-chill 4° to 6° below the normal target temperature before the event starts; by pre-chilling, tenant space is still comfortable by the end of the event. This can also be done with a single click using the Coris system.
