Intelligent environmental monitoring system for office buildings

Intelligent environmental monitoring system for office buildings applies IOT technology to monitor indoor temperature, humidity, light, particulate matter (PM2.5/PM10), carbon dioxide, VOC, formaldehyde, noise, oxygen and other environmental factors, collects the required data and transmits the collected data to the monitoring terminal and display terminal in real time. The collected data is transmitted to the monitoring terminal and display terminal in real time, so that the management personnel and visitors can view the environmental data through the monitoring terminal and multimedia display screen.

Indoor Pollution Sources

In a modern office environment, there are many sources of pollution, including ozone and hydrocarbons generated by various types of office equipment (printers, etc.), formaldehyde, ammonia, benzene, VOC and other toxic and harmful gases emitted by office decoration and office furniture, as well as various types of respirable particulate matter (PM2.5, PM10, etc.).

Intelligent environmental monitoring system for office buildings program, as a component of the building automation system, in the protection of the health of the working environment, increasingly highlights its application value. Fully networked deployment creates a “visible” environment for users.

Regulations and Indoor Air Quality Monitoring

Commercial buildings are increasingly demanding real-time indoor air quality monitoring and building automation. Employee exposure to indoor pollutants is increasingly under government scrutiny. Recently, the U.S. Environmental Protection Agency announced the Clean Air Challenge for Buildings, a set of guidelines for indoor air quality in public places.

 

Currently, regulations on indoor air quality focus on carbon monoxide levels, but in the future there may be regulations that require detailed data and evidence that the air does not cause other health problems.

 

For example, New Jersey has an indoor air quality standard that regulates buildings occupied by public workers during normal business hours.

 

This is one of the indoor air quality regulations in the United States, but it won’t be the last. Public employers are required to check carbon dioxide levels and ensure that building HVAC automation systems are operating effectively.

What is a building automation system?

A building automation system (BAS), sometimes referred to as a building management system (BMS), is a network of integrated equipment that allows a building to run smoothly and efficiently.

Whether it’s a commercial air conditioning unit, lighting, security, scheduling or energy management, it’s likely to already have some form of automation. There is a growing need for BAS in commercial applications.

A BAS acts as a computer network system that monitors and controls various building components.

The whole goal of BAS is to collect different build systems and help them communicate across platforms, software and languages.

Benefits of Building Automation

Building automation controls with Intelligent environmental monitoring system for office buildings offer a number of benefits. For example, IoT automation is critical for energy efficiency and heating, ventilation and air conditioning (HVAC).

According to a recent study by the Pacific Northwest National Laboratory, a properly tuned building management control system can reduce commercial building energy consumption by approximately 29 percent.

BAS can also help control a building’s thermostat and collect data on indoor air quality, temperature and humidity.

How Intelligent environmental monitoring system for office buildings can control air quality

Indoor air quality sensors can be used in conjunction with Demand Controlled Ventilation (DCV) and integrated with the BAS. This will provide dynamic data and visibility of the DCV in operation. the DCV will optimize the building based on occupancy demand.

Indoor air pollution can be divided into two broad categories. Some of the pollution comes from humans and some from exhaust gases not related to human activity.

The needs of high-traffic days are very different from those of evenings and nights when occupancy is low.

When building occupancy is low, there are fewer sources of indoor air pollution. Therefore, excessive ventilation rates are not required to improve indoor air quality.

Occupancy can also be measured by metrics such as ticket sales or security card swipes. Carbon dioxide buildup can also vary by occupancy rate.

DCV can also be applied to empirically predicted schedules. Occupancy can be estimated based on known scheduled use or expected occupancy based on repeated historical data. As a result, the ventilation rate of a conference room can be maximized when the room is booked and reduced when it is not in use.

CO2 Sensor is an important factor in controlling ventilation on demand. Facility managers can use additional inputs from TVOC (Total Volatile Organic Compounds) sensors.

Its helpful to measure occupancy and ensure adequate air quality, as VOCs are a significant indoor air pollutant.

Keeping an eye on indoor air quality conditions

Particulate matter is another concern for indoor environmental quality. High levels of outdoor particulate matter can significantly affect IAQ.

Buildings may be located in areas with high levels of outdoor air pollution. Pollution events such as wildfires can also increase outdoor particulate matter.

Facility managers can combat this pollution by using outdoor and indoor Particulate matter sensors. This helps automate air filtration and ventilation and optimize indoor air quality for building management systems.

For example, sometimes outdoor Particulate matter levels are higher than indoor levels. If this is the case, the air recirculation rate should be increased to mitigate the intrusion of outdoor air pollution.

Conversely, if indoor particulate levels are high, facility managers can take the opposite steps. Particulate matter sensors are critical because they can help manage air filtration systems. Indoor particulate readings help facility managers understand whether current air filtration is adequate.
