What is the N3smart portal?

• The N3smart portal is also called the operations portal and this is where you will find all the data associated with the sensors you have at your locations.

   

  The portal gives you an overview of:

   

  N3smart – activity sensors in entrance areas and in carpet banks

  N3Assets – activity sensors on floor washing machines and other washing equipment

  N3Environment – sensor that measures and provides data on indoor climate

   

  In the portal, you will see statistics, you can retrieve reports and you can also activate notifications (Notifications) which means that you are notified in the event of deviations from the set cleaning plan or in the event of deviations in the indoor climate.

How do we use the data we get in the portal?

• The portal with a solution for notifications in the event of non-conformities will always ensure that you have control that planned cleaning is carried out according to the time set.

   

  Furthermore, you will be able to retrieve current or older data at any time to document and ensure quality time spent on cleaning or indoor climate status via the report solutions we have.

   

  If necessary and by further agreement, advisers from N3 will also contribute with a review and assessment of the data you collect. We will then provide our input on the analysis of data and which measures we recommend based on the measures packages we use in collaboration with the Norwegian Asthma and Allergy Association (NAAF).

   

  Finally, you as a user will also be able to go to the package of measures for indoor climate on the page that has been developed in collaboration with NAAF. You can find it by clicking here.

What does the Finish time show for completed cleaning?

• What do finish times mean?

  Finish time is the time when the sensor in a machine (carpet beater or other floor washing machine/robot) sends data to the server and shortly afterwards it is displayed in the portal as you can see in the example below.

  

  The sensors work so that they start recording data after 1 minute of activity and send data when the sensor has been inactive for 15 minutes. This means that Finish time shows the finish time plus approx. 15 minutes for when cleaning has been completed. If it says 09.30 on the Finish time, the cleaning is finished at about 09.15.

   

  Why do several zones have the same end time?

  As you can see from the picture above, several zones may have registered the same Finish time for cleaning. This is completely correct according to how we register data since the end time is the time data is sent from the sensor to our server.

   

  This means the following:

  If, for example, the same carpet banks are used on several entrances without the carpet banks standing still for a minimum of 15 minutes between cleaning each entrance - the Finish time for all of these will be the same - as in the example above.

High temperature in the first hours on the dust meter

• Why does the dust meter show such a high temperature in the first hours?

   

  The dust meter (N3smart Indoor Air Quality Sensor) runs on electricity, but there is also an emergency battery inside the sensor that will be used if the power goes out, for example.

   

  When the dust meter is installed, this emergency battery will be fully charged and it then emits some heat, which in turn means that the temperature displayed is 2-3 degrees higher than usual. However, this normalizes quickly and after a maximum of one day the displayed temperature will be correct.

How long does the emergency battery in the dust meter last?

• The lifetime of the emergency battery in the dust meter is around 66 hours. This means that in the event of a power cut or when someone accidentally pulls out the plug, the battery will last between 2 and 3 days.

How many users can we have in the portal and how much does it cost?

• Free number of users

  There is no limit to the number of users you can have in the portal. As a customer, you choose this entirely yourself and your administrators can register new users themselves.

   

  No additional cost for users in the portal

  There is no extra cost regardless of the number of users you have in the portal. The price for the solution is controlled based on the subscription to the sensors you have.

How does the outdoor environment affect the indoor climate?

• Utemiljø an important supplier of indoor climate and HSE.

   

  How the outdoor environment is organised, maintained and operated has an impact on the indoor climate and HSE in the workplace. Simple measures such as regular cleaning of walkways for sand and debris. Facilitating scraping ridges outside the outer door and moisture-absorbing mats inside the outer door are installations that contribute to less wear and tear on floor coverings and bone wax.

How does temperature affect indoor climate?

• Indoor climate – Temperature conditions
  The thermal environment deals with thermal conditions in the building, the temperature conditions, and how each individual staying in the room should manage to stay warm indoors. There are five different factors that come into play, more specifically air temperature, air humidity, air speed, radiation temperature and temperature variations. In addition, personal factors such as clothing and level of physical activity in the room in question must be taken into account.

   

  Requirements specifications
  The recommended indoor temperature is between 20 °C and 24 °C in winter, and between 23 °C and 26 °C in summer. Exceedings are accepted in the summer, but preferably no longer than two weeks according to the Directorate of Health. TEK17 recommends 19-26 °C for the combined effect of thermal radiation and air temperature for light work. The Norwegian Labor Inspection Authority and NAAF emphasize that the indoor temperature should be lower than 22 °C during the heating season. The floor temperature should be between 19 °C and 26 °C, the vertically measured temperature difference must not be more than 3 °C per meter and the maximum air speed is 0.15 m/s. This is to avoid the experience of drafts.

   

  Health effects
  If a room has too high temperatures, this can cause concentration difficulties, fatigue, dry skin, dry mucous membranes, headaches and respiratory tract irritations. The experience of dry air can also be due to high temperatures. In the case of too low temperatures or drafts, which are often experienced at air speeds higher than 0.15 m/s, one can experience restlessness and muscle tension.

How does humidity affect indoor climate?

• Indoor climate – Humidity
  The thermal environment deals with thermal conditions in the building, the temperature conditions, and how each individual staying in the room should manage to stay warm indoors. There are five different factors that come into play, more specifically air temperature, air humidity, air speed, radiation temperature and temperature variations. In addition, personal factors such as clothing and level of physical activity in the room in question must be taken into account.

   

  For the atmospheric environment, the focus is on the air quality of the indoor air we breathe, as well as static electricity and air ions. Indoor air can contain particulate matter from organisms such as bacteria, viruses, allergens, molds, mites, algae and inorganic dust and fibres, as well as odours, steam and gas.

   

  Requirements specifications
  Indoor humidity arises from building materials and users of the building. If there is insufficient ventilation, the relative humidity (RH) will be too high. RH is the ratio between the amount of water vapor in the air and the maximum content of water vapor the air can contain in a saturated state. In winter, when temperatures are low, the humidity should be low, with a RH of between 20-40%. In summer when the temperatures are higher, the RH can be up to 60-70%.

   

  When air with a high RH is cooled against cold surfaces, condensation will occur, which provides a good basis for microorganisms to grow on organic materials or on dust that collects on surfaces. Other sources of moisture are leaks from installations, building moisture and water penetration from external sources. According to SINTEF Byggforsk, 76% of all process-caused building damage is due to some form of moisture. Moisture and mold damage must not occur indoors and must be removed.

   

  Health effects
  High humidity can give an experience of heavy air, where headaches and fatigue can occur. With condensation in the building, it is also possible to develop respiratory diseases, in addition to the risk of microbial growth. Microbial growth can damage building materials and construction, and cause several health symptoms in humans. These symptoms include asthma or worsening of asthma, wheezing, upper respiratory tract infections and allergic alveolitis. Allergic alveolitis is a general term for lung diseases that are caused by an inflammatory reaction in the lung tissue after breathing in organic dust, such as fungi or bacteria.

How does Co2 affect indoor climate?

• Indoor climate – Air quality
  For the atmospheric environment, the focus is on the air quality of the indoor air we breathe, as well as static electricity and air ions. Indoor air can contain particulate matter from organisms, such as bacteria, viruses, allergens, molds, mites, algae, inorganic dust and fibres. Odour, steam and gas also occur.

   

  Requirements specifications
  In order to maintain good air quality, the recommended maximum air content of CO2 is 1000 ppm in public and work buildings, which is 600 ppm more than the basic level of CO2. The proportion of CO2 in the air depends on the activity exercised, and is proportional to the number of people in the room. In classrooms, the supply of fresh air must be at least 26 m3/h per person, on the basis of air pollution from people during light activity. It is important that the ventilation in the premises works in such a way that the given limit value is not exceeded, and the fresh air supply must therefore be adapted.
  The amount of air pollution also depends on the room's materials, installations and products. Therefore, the fresh air supply must be at least 2.5 m3/h per m2 when the room is in use and 0.7 m3/h per m2 when the room is not in use. Rooms with special pollutants, such as toilets, must have an exhaust so that the air quality in the room is satisfactory.

   

  Health effects
  If the air quality is too poor, the students' ability to concentrate and learn will deteriorate, they may get headaches and experience fatigue, and respiratory irritation and worsening of asthma may occur. One can also experience various complaints from bad smells, and some can develop perfume intolerance.
  The degree of humidity can also affect health. If the humidity is too low, you can get a feeling of dry hair and skin, dry mucous membranes and problems with your eyes if you wear contact lenses. Dry air does not have to be caused by too low humidity, but can be due to high temperatures, or dust and other particles in the indoor air. With high humidity, you can get an experience of heavy air, where headaches and fatigue can occur. It is also possible to develop respiratory diseases due to condensation, such as asthma, and microbial growth can occur which can cause building damage.

What happens if we lose or destroy a sensor?

• If you should lose a sensor or destroy a sensor, it is important that this is reported to N3 as soon as possible. Then contact us on 02131 or kundeservice@n3.no so that we can help you.

   

  The procedure will generally be as follows:

   

  • You report which sensor is broken/lost and that you need a new one
  • N3 registers a new sensor in the portal
  • N3 sends over a new sensor to you per post that you install yourself. You will receive help from our Customer Success Team via Teams/telephone if you need this
  • Any damaged sensor is placed in the box and sent back to N3
  • There is a one-off cost for a new sensor in accordance with the current price list that is invoiced when a new sensor is sent
  • The subscription price will remain the same

Is data from sensors stored even if they are not connected to the network?

• All SIM-based activity sensors, whether for carpet cleaners or robots/machines, can stack up to 50 messages if, for one reason or another, they cannot connect to the mobile network or server.

   

  In practice, this means that data can be stored for many days, given that there are few activities per day before some data is lost.

   

  As soon as a device reconnects with the network and sends data to our server, the buffer is emptied using the FILO principle, i.e. first in-last out, i.e. the most recent data always arrives first, and then historical data back in time buffered from previous activities.

   

  For Activity sensors with BLE, data will be stored for up to 7 days before overwriting starts.
