The OED system has a number of features. This page highlights some of the more important ones. A nice way to see many of these features is to try looking at our released/production system at production system or you can look at our demo system that has features that are almost ready for production release at demo system. We also have a development system with features that are being prepared for release. People interested in seeing these features and providing feedback should contact the project.
The OED system can display the energy data it has acquired. You can
choose what meter(s) and/or site defined group(s) that you want to
graph. Currently the data can be displayed as a line or bar chart
where you can select the time duration represented by each bar.
The system can also show comparison of current usage over a
specified period of time to the past. When you are only part way
through a time period, e.g., one week, then an estimate is given of
expected usage for the whole time period based on usage to
date. This is under development and currently compares the current week to the
The OED system allows a site to define any arbitrary combination of meters or other groups and save this by an administrator of the system. For example, you might have three floors in a building named DormOne with each one having a (sub)meter. You could create a group named Dorm1 and select these three meters to include in this group. If you now select Dorm1 to graph you would see the total energy used by these three meters as a single line or bar. Suppose you do the same thing for DormTwo which has four meters. Graphing Dorm2 would show the total for these four meters. You could also select to graph Dorm1 and Dorm2 at the same time and that would show two lines/bars where each showed the total usage for one dorm.
Groups can also be used the same as meters. Let's assume you have a total of three dorms where Dorm3 only has a single floor with a meter named meterDorm3. You could create another group and name it AllDorms where you place the groups Dorm1 and Dorm2 and the meter meterDorm3 into this group. Now, if you graph AllDorms you see the total energy for these three dorms. You could also graph Dorm1, Dorm2, meterDorm3 and AllDorms on a single graph to see the usage level of each dorm along with the total for all the dorms.
This system is very general. Thus, you can create a group of all the first floor meters if you wanted. If you then combined this with the AllDorms group you would be including the first floor meters two times. Don't worry, the system will automatically figure this out and only count each unique meter.
There are many requests for meter groupings that this addresses (it should do them all). For example, you could have a group for renewable energy, food service energy, athletic energy, etc. You can then combine them to get all residential usage or the entire campus usage. The difference in OED is that you can decide, create, and use any grouping of meters at any time so it is all under your control. This means you don't need to ask OED to do what you want. The flexibility is built into the system.
OED allows for creation, editing and deletion of groups.
Here is the system editing groups where you can see there are three types of floors
(first, second and third). The figure shows the members of the first and second floors containing
meters and the three floor (first, second and third) groups combined
to form a new group of all the floors in all three buildings:
Here is a graph combining the three floors (first, second and third) groups and all floor group with the Aldrich Ground meter. This was needed since the ground floor is not included in the other three floors. This also demonstrates you can graph any arbitrary combination of groups and meters:
We are committed to making our system open. That goes beyond just the software to the information inside of our system. Thus, you can export the data represented on any graph as a CSV file (a non-proprietary file similar to a spreadsheet and readable by all spreadsheet programs). If you want all the data then you can simply graph a wide range of dates to get that. We have worked hard to make the graphing system fast and responsive so graphing large date ranges with lots of meters will not be an issue. We feel this is a nice feature since you can look at the data visually before you decide to export it. This will allow you to do your own analysis of the data or import it into other systems. The figures above show the button to click to export the graph data.
We also support import of data into our system. You can create a CSV file (can use a standard spreadsheet program to do this) with one column as the data/time and another with the energy reading. You can then import that file into the system via a web page on the OED system. The data will now be available in the same way as if it was read from a meter. You can import data for a meter that is not automatically read or to add missing data from a meter already in the system. This has been used to bring in historical data before the system was in place.
We can read in certain types of data from Johnson Control's Metasys export. This allows you to transfer information from that system into our system. This is somewhat trickier than a straight CSV file since the data may be the energy usage from the previous reading, cumulative and/or reset at midnight. If you have data from another system then please contact us as we are willing to try to import it into our system. Also, since this is an open source project, either you or another vendor could create the software to do this.
OED is built on a modern framework of software that
automatically adjusts to the screen resolution. Thus, menus will
adjust size and ultimately become dropdown as the screen size (really
the browser window) gets smaller. This means the system will work on
everything from a large monitor to a tablet to a cell phone. We are working to make
this even more responsive,
but here is a screen shot on a lower end smart phone with 480x800 pixel
and if you click on the options button a menu will appear (this would be visible on a higher resolution screen as shown in the images above):
There are many features that are planned in the coming months and in the longer-term. Please visit the release page for more information.
