Meeting Room CO Monitoring Malaysia Why Conference Rooms Need Indoor Air Quality Monitoring Introduction A meeting room may feel perfectly comfortable when it is empty. The air conditioner is running. The temperature feels cool. There is no obvious smell. But once 8, 10 or 15 people enter the room and close the door for a long meeting, indoor conditions can change. One of the most useful parameters to monitor is: CO In occupied indoor spaces, CO monitoring can provide useful information related to occupancy and ventilation. For offices in Malaysia, meeting rooms, conference rooms and training rooms are particularly useful locations for CO monitoring because occupancy can change rapidly throughout the working day. Why Meeting Rooms Are Different from Open Offices An open office may have: Larger floor area More air volume More distributed ventilation More movement between areas A meeting room is often: Smaller Enclosed Highly occupied for short periods Closed during meetings This means environmental conditions can change much more quickly. An Empty Meeting Room Can Look Perfect Imagine checking a meeting room at 8:30 AM. The room is empty. CO is relatively low. Temperature is comfortable. Everything appears normal. At 10:00 AM: 12 people enter. The door closes. The meeting lasts 90 minutes. The environmental condition at 11:00 AM may be very different from the condition measured before the meeting. This is why measurements should reflect actual occupancy. Why CO Increases in Occupied Rooms People produce CO when they breathe. When several people occupy an enclosed space, CO can accumulate if ventilation is insufficient relative to occupancy. The rate of change depends on factors such as: Number of occupants Room size Ventilation Meeting duration HVAC operation Door opening Monitoring helps show how the actual room behaves. “The Air Conditioner Is On, So Ventilation Must Be Good.” Not necessarily. Air conditioning and ventilation are related building services, but they are not the same thing. An air-conditioning system may provide: Cooling Recirculation Filtration The amount of outdoor air supplied depends on the actual HVAC design. Therefore: Cool room ≠ Automatically well-ventilated room CO monitoring can help facility teams investigate this. Why People Describe Meeting Rooms as “Stuffy” Employees may say: “The room feels stuffy.” “I feel sleepy during long meetings.” “The air doesn't feel fresh.” “The room is okay atfirst, but not after one hour.” These comments can have many possible causes. Instead of guessing, facility teams can collect environmental data. Monitor CO Throughout the Meeting A useful investigation is: Before Meeting Record CO. ↓ Meeting Starts Record occupancy. ↓ 30 Minutes Observe CO. ↓ 60 Minutes Observe trend. ↓ Meeting Ends Continue monitoring. ↓ Observe Recovery This provides much more useful information than one reading taken when the room is empty. Recovery Time Matters Too After people leave, CO should change as the room exchanges air. Monitoring the recovery period can help facility teams understand how quickly the room returns toward its unoccupied condition. This creates a useful pattern: Empty Room ↓ People Enter ↓ CO Rises ↓ People Leave ↓ CO Falls Historical monitoring makes this pattern easy to see. Compare Different Meeting Rooms A company may have several meeting rooms. For example: Meeting Room A 6 persons Meeting Room B 10 persons Conference Room 20 persons Training Room 30 persons The ventilation performance of each space may be different. A portable CO monitor can help compare them. Temtop C10 2nd for Meeting Room CO Monitoring For straightforward monitoring involving: CO Temperature Relative humidity the Temtop C10 2nd can be considered. It is particularly suitable for general indoor applications such as: Meeting rooms Conference rooms Training rooms Offices Classrooms Home offices For users whose main question is: “What is the CO level in this room?” a CO-focused monitor is often the logical starting point. Temtop M100 for CO + Particulate Monitoring Some offices need more than CO. During haze in Malaysia, companies may also want to monitor: PM2.5 PM10 CO AQI For this type of application, the Temtop M100 can be considered. This makes it useful when the company wants to investigate both: Ventilation-related conditions and Haze / particulate conditions. Temtop M10 for Broader Indoor Monitoring Where the requirement includes: CO PM2.5 VOC Temperature Relative humidity the Temtop M10 can be considered. Its supported connected functions can also be useful where users want to observe environmental changes over time. Which Model Should You Choose? A simple way to select is: Temtop C10 2nd Choose when the main requirement is: CO + Temperature + Humidity Temtop M100 Choose when the requirement includes: CO + PM2.5 + PM10 + AQI Temtop M10 Choose when the requirement includes: CO + PM2.5 + VOC + Temperature + Humidity + Connected Monitoring The correct model depends on the monitoring objective. Meeting Rooms During Haze Haze creates another challenge. An office may keep: Windows closed Doors closed Building openings reduced to limit outdoor particulate pollution entering. However, meeting rooms remain occupied. This creates a situation where facility teams may want to monitor both: PM2.5 and CO rather than focusing on only one parameter. PM2.5 Low, CO High This situation is possible. For example: Windows closed Air purifier operating Meeting room occupied Limited ventilation PM2.5 may be relatively controlled while CO increases. This demonstrates why one environmental parameter cannot describe every aspect of indoor air quality. CO Low, PM2.5 High The opposite can also occur. For example: Outdoor haze Significant outdoor air entering Low room occupancy CO may appear relatively low while particulate concentration is elevated. Again: CO and PM2.5 answer different questions. Training Rooms Training rooms deserve special attention because they may contain many people for: One hour Half a day Full-day training Monitoring can help facility teams understand hw environmental conditions change throughout the session. Boardrooms Boardrooms may also have: Long meetings Closed doors High occupancy relative to room size A room that feels excellent with three people may behave differently with fifteen. Measurement helps show the difference. Interview Rooms Small interview rooms can also experience rapid occupancy-related changes. Even though only two or three people may be present, the room volume may be small. Portable CO monitoring can help investigate these spaces. Video Conference Rooms Modern video conference rooms are often acoustically enclosed. This is useful for privacy and sound control. However, the environmental behaviour of the room still depends on ventilation. CO monitoring can provide useful information during extended video conferences. Meeting Room Occupancy Study A company can perform a simple study. For each room, record: Room name Approximate room size Number of occupants Meeting duration Starting CO Maximum CO CO at end of meeting Recovery time After several meetings, patterns may become visible. Portable Survey Strategy A facility team can begin with one portable monitor. Monday Meeting Room A Tuesday Meeting Room B Wednesday Conference Room Thursday Training Room Friday Boardroom This provides an initial understanding without immediately installing a large system. When Portable Monitoring Is Not Enough Suppose the company has: 20 meeting rooms Several floors Hundreds of employees Management may want to know: Which rooms regularly experience elevated CO during occupancy? Moving one meter around manually becomes inefficient. This is where fixed monitoring becomes more useful. Continuous Meeting Room Monitoring A fixed monitoring system can provide: Real-time readings Continuous data Historical trends Multiple room monitoring Central dashboard Alerts where required This allows facility teams to review environmental behaviour over weeks or months. Example Multi-Room Monitoring System A corporate office could monitor: Meeting Room 01 CO + Temperature + RH Meeting Room 02 CO + Temperature + RH Boardroom CO + Temperature + RH Training Room CO + Temperature + RH Open Office CO + PM2.5 ↓ Communication Network ↓ Central Monitoring Platform ↓ Historical Database ↓ Facility Management This creates a much more complete view of office environmental conditions. Historical Data Historical monitoring can answer: Which meeting room has the highest CO? What time does it normally occur? How many meetings happen before the room recovers? Does the problem occur only at full occupancy? Does HVAC scheduling affect the room? Are Monday and Friday patterns different? This is where continuous monitoring becomes particularly valuable. Use Data Before Making HVAC Changes Instead of immediately changing the HVAC system based on complaints, facility teams can first collect baseline data. A practical process is: Measure ↓ Identify Pattern ↓ Investigate HVAC / Occupancy ↓ Make Adjustment ↓ Measure Again ↓ Compare Before and After This provides a more evidence-based approach. CO Monitoring Does Not Replace HVAC Engineering A CO monitor provides measurement information. It does not by itself determine: Required outdoor airflow Air changes Duct design HVAC capacity Ventilation compliance Where detailed ventilation assessment is required, appropriate HVAC engineering evaluation may also be necessary. From One CO Monitor to Smart Building Monitoring The development path can be: Temtop C10 2nd ↓ Meeting Room CO Survey ↓ Compare Multiple Rooms ↓ Identify Recurring Patterns ↓ Fixed CO Sensors ↓ Historical Data ↓ Central Dashboard ↓ Multi-Floor Monitoring ↓ Corporate Indoor Environmental Monitoring System A relatively small CO enquiry can therefore become a larger building-monitoring project. Example Customer Enquiry Instead of: “Please quote CO meter.” a useful project enquiry could be: Application: Corporate Office Meeting Rooms: 15 Training Rooms: 2 Parameters: CO + Temperature + Humidity Additional Requirement: PM2.5 in common areas Monitoring: 24/7 Historical Data: Required Dashboard: Required Alerts: Required This immediately identifies a larger monitoring opportunity. Information Needed for a Meeting Room Monitoring Proposal Customers can provide: Number of meeting rooms Approximate room sizes Typical occupancy Maximum occupancy Typical meeting duration Required parameters CO monitoring requirement PM2.5 requirement Portable or fixed monitoring Number of monitoring points Historical data requirement Dashboard requirement Alert requirement Number of floors HVAC information if available Floor plan if available This helps determine whether a portable monitor or continuous system is more appropriate.
