The intended audience of this article is partners or power users who are working closely with Noda to setup the system.
Like most things in Noda, we rely on the data coming from the equipment in your building to transform the user interface and support your operations. Floor plans specifically have more stringent requirements so we can show comfort, air exchange, air quality, automated demand management and lighting zone details. We have listed the points Ontology Alignment Project codes we require below.
1. HVAC
Equipment Types
FCU (any equip with base code FCU, except those with variant code FCUZCHOE)
AHU (any equip with base code AHU)
VAV (any equip with base code VAV)
Heat Pumps (any equip with base code HP)
Unit Heaters (any equip with base code FCU and variant code FCUZCHOE)
Radiant Floor Heaters (any equip with base code RADF)
Exhaust Fans (any equip with base code FAN)
An equipment type will be hidden if no HVAC zone on that floor has an equip of that given type.
1a. HVAC - Comfort
Displays if the HVAC Zone has one of the following functions:
HEATING, COOLING
HEATING_COOLING
HEATING_VENTILATION
COOLING_VENTILATION
HEATING_COOLING_VENTILATION
With both cooling setpoint (EFFZTCLSP) and heating setpoint (EFFZTHTSP) available:
With heating setpoint (EFFZTHTSP) only:
With cooling setpoint (EFFZTCLSP) only:
With one setpoint (EFFZTSP for ZT or RATSP for RAT) and no heating setpoint nor cooling setpoint:
Uses the first equip of the selected type within the HVAC zone for the calculation; all other equips are ignored.
If none of the above cases are met, the zone will be grey.
Points
ZT (default)
Cooling setpoint: EFFZTCLSP
Heating setpoint: EFFZTHTSP
Setpoint: EFFZTSP
RAT (may be configured on a per building, per equip type basis, via Noda-api)
Setpoint: RATSP
Cooling/heating setpoints are NOT used
Ex: You have 2 buildings with ACUs and only RAT. You set each building individually to use RAT for ACUs. Then, if you other equipment, like FCUs, they keep the default Zone Temp configuration. Alternately, if one building has ACUs that have ZT and the other only RAT, you can have each building configured to look for the available temp point.
Units
Differential (as seen on diagrams) is 2 if the unit of the point is celsius, 3 if fahrenheit
1b. HVAC - Air Exchange
Displays as a filter if the HVAC Zone has any of the following functions:
VENTILATION
HEATING_VENTILATION
COOLING_VENTILATION
HEATING_COOLING_VENTILATION
Uses the first equip of the selected type within the HVAC zone for the calculation; all other equips are ignored.
Points
ZCO2 (only "ppm" unit is supported)
If between 0-750ppm, the zone is green
If between 750-900ppm, the zone is yellow
If between 900-1800ppm the zone is red
1c. HVAC - Communication Status
Always displays as an available filter.
Points
CMST
An equip is considered online when its CMST curValue corresponds to the first element in the point's enumValues array
E.g. if curValue is "online" and enumValues are ["online", "offline"], the equip is considered online
Considers ALL the equips of the selected type within the HVAC zone
If EVERY equip of the selected type is online, then the zone is green
If ANY equip of the selected type is not online AND there is at least one equip with a CMST point, then the zone is yellow
If NO equip of the selected type has a CMST point, then the zone is grey
1d. HVAC - Automated Demand Status
Displays as a filter if the building has the ADM feature flag turned on.
Points
LDSHST
An equip is consider on when its LDSHST curValue is "true"
Considers ALL the equips of the selected type within the HVAC zone
If ANY equip in the HVAC zone is on, then the zone is blue
If NO equip in the HVAC zone is on AND there is at least one equip with a LDSHST point, then the zone is dark grey
If NO equip of the selected type has a LDSHST point, then the zone is grey
2. Environmental Sensors
2a. Environmental Sensors - Air Quality
Equipment Types:
Any equip that has one of MTS, SURS, OCCS, AIRS, LTS as its base code AND has a variant code with the function AQM according to the OAP
At the time of writing, this corresponds to equips with the variant code EQS or AQS
Specific Measurements:
Includes CO (ZCO), CO₂ (ZCO2), CH₂O (ZCH2O), NH₃ (ZNH3), NO₂ (ZNO2), Ozone (ZO3), PM01 (ZPM01), PM2.5 (ZPM25) , PM10 (ZPM10), TVOC (ZTVOC)
Measured as Unhealthy, Moderate, or Normal (see legend within Noda for the ranges for each measurement)
Note that the ranges might change depending on the unit of the point
Overall Measurement:
For each measurement type calculate the IAQ based on linear interpolation within the "Normal" range
Choose the lowest IAQ Score
If the score is Moderate/Unhealthy, subtract 2 points for each additional measurement that is in the same range (i.e. also Moderate/Unhealthy)
2b. Environmental Sensors - Gas Detection
Equipment Types:
Any equip that has one of MTS, SURS, OCCS, AIRS, LTS as its base code AND has a variant code with the function TCGM according to the OAP
At the time of writing, this corresponds to equips with the variant code GDS
Specific Measurements:
Includes CO (ZCO), NO₂ (ZNO2)
Measured as Unhealthy, Moderate, or Normal (see legend within Noda for the ranges for each measurement)
Note that the ranges might change depending on the unit of the point
Overall Measurement:
Identical to Air Quality sensors
3. Lighting Zones
Points
EFLTLVLSP
0, the zone is yellow" } ], "type": "paragraph" }" data-slate-object="block" data-key="825"If curValue > 0, the zone is yellow
If curValue is 0, the zone is dark grey
If no EFLTLVLSP point is found, the zone is grey
