How to use the innovative LPWAN technology to achieve efficient use of workspace
In the past decade, the workplace has changed dramatically. From large companies to small startups, workplaces have become more flexible and quickly transformed into a “anytime, anywhere†concept. As a result, expensive office space is not being used effectively.
Office space expenses are the second-largest operating expense after wages, and the annual cost of each workplace continues to rise globally. According to an office space research report released by Cushman & Wakefield, Hong Kong and London have expensive office market, while in New York and Silicon Valley, office occupancy costs increase by 6% per year.
Field workers need to have the right workspace, whether they work in the office every day, or only a few days a week to attend meetings and collaborate with colleagues. Companies need to work hard to achieve the goal of efficiently saving and shrinking office space, while creating a pleasant and efficient work environment.
A new survey of nearly 400 multinational companies by real estate company CBRE found that two-thirds of companies plan to adopt shared office by 2020. Their research also shows that Millennials regard the overall workplace experience as a decisive factor in accepting a job. Millennials believe that their office is not just a workplace, but also a community where they can participate.
Use technology to solve space utilization challenges
How to monitor the use of desks and conference rooms to ensure adequate space has been a challenge for many facilities and office providers. The emergence of new low-power wireless connectivity technology and the less-obtrusive occupancy sensor that is compatible with the GDPR standard is replacing the cumbersome manual approach to solve this problem.
In response to new demands in the modern office environment, Semtech and OpenSensors work together to leverage the Internet of Things (IoT) technology and provide a proven space utilization management solution. Semtech's LoRa devices and radio frequency technologies (LoRa devices and LoRaWAN protocols) have evolved into a global standard for low power wide area network (LPWAN) connectivity.
A LoRaWAN-based network, coupled with LoRa-enabled sensors and gateways, forms the foundation for a remote, low-power, flexible application solution that delivers cost-effective, reliable communications and captures accurate data. To understand how the team works.
In the smart building application scenario, the technical advantages of the LoRa device and LoRaWAN protocol include:
· Provide low power, remote sensing
· Easy to install small 1.5-inch wireless sensor
· Long battery life
· Open standards, security and proven reliability
Use data to drive workplace optimization
A comprehensive space management strategy based on historical data enables companies to make decisions about the current needs of the facility and to anticipate future needs. Before an organization considers iterative and influential changes to its work environment, there are some key factors that must be benchmarked. By monitoring usage and the ratio of people to desks, companies can make more informed decisions about the mix of their facilities and office space.
The first is to define business goals: Do you need to switch to an activity-based work environment, improve space capacity planning or initiate a workspace redesign project? With clear goals, the process will be more specific to the appropriate integration solution and the indicators that need to be monitored. Clear. Key data points that need to be measured include:
Average and peak utilization
The first data point is the average utilization of desks and meeting rooms. Previously, this was done by manually recording the number of employees on each floor or business unit, and today, with the power of the Internet of Things, occupancy sensors are an effective way to analyze how buildings and office space are being utilized and provide real-time data every day. .
Monitoring usage will generate average and peak usage of office space. For most companies, the average utilization rate of workstations is 45%-50%, and the utilization rate of conference rooms is around 40%. The utilization rate of each item should be between 60% and 80%.
After getting at least one month of data, the staff can gain insight into trends and anomalies. Office desk and conference room occupancy rates are also significantly different on different days of the week and in different business units. These key data identify the employee's work patterns and optimize the workspace and provide the following recommendations:
• Encourage people to enter during off-peak hours
• Work at home during peak hours
• It is recommended that employees choose other places with lower utilization rates during peak hours.
2. Ratio between staff and desk
New space management trends have led organizations to move to a flexible and agile work framework and transform units into more flexible work environments. Companies are shifting from 1:1 (one desk at a time) to a desk for two or more people. Sensor data helps determine the ideal ratio for each team, department, or building.
For example, a highly mobile sales team is very different from the finance department that enters the office every day and needs a fixed desk. The finance team needs a 1:1 desk-to-person ratio, and the sales team can easily operate at a 1:5 ratio, with most modern companies averaging between 1:1.2 and 1:2.
Increasing the ratio of people to desks can be achieved:
· Improve the utilization of the workspace (for example, desk space is always in use)
· accommodate more employees in a building or a facility without having to rent more office space.
3. Small changes can save a lot of cost
Anonymized and GDPR-compliant information about occupant occurrences, location, occurrences, and activity can be used to optimize facility management, and a 10% increase in occupancy will have a significant impact. For example, in Silicon Valley, the cost per desk is $15,000. If you use 10 flexible desks or a sharing strategy, you can save $150,000 a year.
In addition to optimizing space, employers need to continue to solicit feedback after the change is launched to ensure employees receive a high level of happiness and productivity.
Four small changes produce results:

“When I talk to the company, they often tell me that they want to reach 80% usage. This is a very ambitious idea, but I encourage them to start from a bit of change, because 10-20% change can actually Bringing a huge difference." -Yodit Stanton, CEO and founder of OpenSensors
How to deploy an intelligent building system
Deploying an intelligent building system requires an end-to-end managed solution service and a corresponding provider that enables organizations to understand how their workspace is being used. Explore the Smart Building System Practice with OpenSensors, analyze the “how to†deployment and propose recommendations for maintaining an intelligent building system in five steps:
Site survey
Assign a project manager to oversee a team of IT staff and key stakeholders. Start by identifying any potential risks that need to be mitigated and predicting potential problems that may hinder the smooth operation of the project, review and select a provider and service provider who can be responsible for solution design, hardware, and logistics solutions to ensure technical goals and established business. The goal is consistent with the KPI.
The service provider will begin its process by establishing a detailed site survey plan, and they will evaluate the location to place sensors and gateways to achieve large signal strength. OpenSensors uses a star network configuration that places one gateway per layer (or every two layers) to serve hundreds of sensors.
2. Select sensor
Next, the service provider will purchase the appropriate battery-powered sensors to match the established goals and data that the company wants to measure. Because the LoRaWAN protocol is an open standard, sensor network providers can access hundreds of interoperable sensors and gateways from different professional manufacturers, such as those with membership in the LoRa Alliance.
The three sensors commonly used in the work area are:
• Passive infrared (PIR) sensors installed under the desk to provide data for anyone who stays at the desk or in the conference room for more than 10 minutes.
• Conference room passive infrared sensors measure occupancy, and they have a wide focus range for higher accuracy.
• Meeting room counting sensors are available for smaller meeting rooms that can capture the number of people entering and leaving the room.
• The footstep sensor has a wider focus area that allows people to travel in different directions. The captured data helps building managers understand the use of open areas such as entranceways and shared spaces. Various sensors for tracking environmental factors such as noise, brightness, temperature and air quality can also be integrated into intelligent building systems.
3. Connect to the network
One of the main considerations for intelligent building systems is how to reliably transmit signals from sensors to gateways and then to the cloud-based platform. Technologies such as Bluetooth or Wi-Fi have difficulties in transmission and frequency issues within buildings. Relatively speaking, LoRaWAN is the ideal network protocol for intelligent buildings. Devices from different manufacturers using this technology provide seamless interoperability with each other. The LoRaWAN-based network, combined with LoRa-enabled sensors and gateways, provides the necessary long-distance, low-power connectivity for cost-effective and reliable data communication.
LoRaWAN is available on both public and private networks. Enterprises can create a private network based on LoRaWAN that gives building owners complete control over data from sensors, gateways to the Internet, or individual local servers.
The data is transferred to the platform and displayed in real time on the display interface. The network is completely isolated from the corporate Internet and IT resources. To further ensure proven end-to-end device security, consider deploying a gateway with TLS security and sensors that use AES encryption.
4. Division phase and implementation
Install the hardware kits in stages and test each configuration before it is implemented in the building at the site. This preparation phase eliminates potential challenges and ensures that the system meets quality standards. With proper planning and preparation, installations can usually be completed during off-hours. For example, OpenSensors deployed a system with more than 2,000 sensors for a financial services customer during the weekend.
These sensors are compliant with the GDPR standard and do not collect any personal data. They only measure the occupancy of a desk or conference room and are not connected to a specific individual. It is important to inform the employee of the space utilization management system immediately before and after installation.
5. Delivery
After the device is deployed, a customized display interface allows you to display real-time metrics for each KPI, including visualizations and blueprints. The solution includes an asset management feature that makes it easy to manage and track each sensor deployed and synchronize with the floor plan when changing locations.
In addition, data needs to be analyzed to provide unbiased recommendations. By establishing a monthly or quarterly centralized meeting, you can monitor progress and make the necessary adjustments to your strategy. Continuous training on how to manage the analytics platform and evaluate monitoring reports is also provided throughout the life of the project.
Summary: use space to reach its full potential
Modern workplaces significantly reduce operating costs by incorporating activity-based work principles into workspace design. Companies that monitor the way their employees work can create an environment that enhances the employee experience.
The digital transformation in commercial buildings has begun and is gaining momentum. Companies of all sizes can benefit from the IoT revolution, which has brought new efficiencies to facility management. Most workplace management systems generate a return on investment within a few months of deployment.
Data-based occupancy data from smart sensors eliminates guesswork and provides the team with actionable data to improve the workplace; it also provides the basis for future designs to accommodate a growing workforce. Ultimately improve employee output.
