Coefficient (mathematics/statistics)
A constant value multiplies a variable by its value. For example, in the following formula, ‘
‘2’ is the coefficient in front of the variable ‘x’. This means that every value of x in the formula is multiplied by 2. Similarly, the coefficient doesn’t have to be a number but can be a letter, representing an unknown, unchanging number. For instance in
‘a’ and ‘b’, are coefficients, and the letter ‘c’ represents a constant value. (Source: Wolfram Alpha)

A Coppertree logical concept to describe a subset of a site by means of a set of device number ranges. (e.g. device 100..199, 2000..3999). Multiple device ranges may be used to completely describe the location. Locations are commonly used to describe the individual buildings within a campus-wide site.
Location ID
Kaizen assigns a unique building ID named for every building added so that the information collected from the buildings through CopperCube will populate the correct locations in the database.
Logic Block
The fundamental building element forms a logic flow. There are three types of logic blocks:
- Input Blocks: Provide input e.g., weather data, trend logs
- Function Blocks: Process 1 or more inputs and generate 1 output
- Output Blocks: Output the data for storage i.e. Calculated Trend Logs

A polling Trend Log collects data at consistent user-defined intervals (every 15 minutes, once a day, etc). The other option is a ‘CoV’ Trend Log.
Q
R
Report
A snapshot of information at a particular point in time for a particular period of time. Kaizen can create Reports that render processed data into a visual format such as a graph or table. Reports are scheduled to be run and delivered via email to users or groups who have subscriptions to the report.
- Reports can be run on demand.
- Reports can be scheduled to run at a specific time schedule on a recurring basis; see subscription.
RTU
Roof Top Unit – an Air Handler Unit which heats and/or cools air located on the roof of a building.
Rule Template
A logic template that contains the Logic Flow and allows users to set parameters such as Insight type, trigger block, trigger type, and aggregation interval.The template from which Working Rules are created. Users can download Rule Templates into their building from the Community Library, copy from an existing Template or create them from scratch.
S
SaaS
Software as a Service – a software delivery model in which software and associated data are centrally hosted on the cloud. Sometimes referred to as “on demand” software.
Schedule-driven
Refers to a task such as automatic report delivery via email initiated by a schedule where the exact date and time are defined.
Site (CopperTree)
A SET of BACnet devices that may communicate using only BACnet protocol. The devices are uniquely numbered within the SET. The SET may contain one or more interconnected BACnet networks (i.e. an Ethernet backbone & several mstp networks). Graphically a SITE is depicted as:
- Two examples of a SITE:
Below is a diagram which is NOT an example of a SITE; since the devices on A cannot communicate with the devices on B. This is TWO SITES: - Not a site – but rather this is 2 separate sites.:
Be aware: Delta partners and Delta/CopperTree customers often use ‘site’ to describe a collection of BACnet devices belonging to a given client (i.e. City of Edmonton) or which are geographically co-located (i.e. SFU campus) as a site. But this is often incorrect as the collection of devices does not meet the strict definition of SITE – i.e. not all the devices can ‘see’ (communicate) with each other. - Quattro uses the above definition of SITE. Quattro is MULTI-SITE capable, since it may communicate with multiple SITES simultaneously. However, the SUPERSET collection of devices created by Quattro’s multi-site capability does NOT make the SUPERSET a SITE. E.g: The collection [C] is NOT a SITE. It remains multiple distinct SITES [A] and [B].
- Quattro as a Multi-SITE (SUPERSET):
Subscription

T
Tag
Kaizen Systems adds a tagging model to allow descriptive data within Kaizen. Tags are simple keywords or terms assigned to a piece of information (such as a BACnet object) and are used to categorize the content. The list of tags available in Kaizen comes from the tags listed and defined by Project Haystack.
Template
See Chart Template or Rule Template.
Trend Log (BACnet)
Also called a TrendLog or TL. A BACnet object that collects data in the form of time-value pairs from a specific monitored object (eg, schedule, analog input, binary variable, etc.). These values can be captured at either regular polling intervals or on a Change of Value (CoV) of the monitored object property. When the time interval passes, or a Change of Value occurs, a log is produced with the property value and a date/time stamp which is placed into a buffer for future retrieval. This buffer can be optionally fixed in size by the user. Trend Log data is used in Kaizen for many types of analytics. ( Source)
Trigger Block
A binary output logic block that can be used to trigger when insight has been detected.
Trigger Type
