Consumer IoT is different than Industrial IoT
Consumer IoT
Low range, Wi-Fi available
Appliances are replaceable
Low complexity

Consumer IoT is different than Industrial IoT
Industrial IoT
Large Facilities, No Wi-Fi widely available
Equipment expensive to replace
High complexity and requires scalability

Commercial Buildings have Building Management Systems (BMS)
To automate individual tasks No data integration or insight into the data Smaller buildings dont have BMS
IoT in Commercial Buildings is Often Overlooked

Dramatically more efficient Building
Operations
-Reduce energy use [30%]-Repair and maintenance
New revenue generation opportunities
-Reselling the data
Differentiation
-Sustainability programs-New Services to tenants
IoT is an easy and cost-effective solution to add tremendous value to a property
Why Now? Technology Enablers & Industry Trends
8
Before:
Solutions that allow you to collect a single type of data have been available, but they are limited and can be expensive
Now:Green Buildings and sustainability trends are helping lower the cost of
sensors, cloud data storage, and connectivity.
Why Now? Technology Enablers & Industry Trends
9
The perfect storm that allows IoT to move to the forefront of this industry
What to look for in a solution to maximize IoT value:
Aggregate multiple types of data Act on the data
Analyze the data

When an equipment has communication capabilities or if there is an existing network of sensors/BMS, IoT devices can be directly connect.
Architecture may vary based on the solution: Each IoT Device can be directly connected to the Internet or each IoT device can connect wirelessly to an
Internet Access Point. Each IoT device can be from a different manufacturer

What is LEED?
15
LEED, overseen by the US Green Building Council (USGBC), is a highly recognized sustainability certification with over 15.7 billion total commercial square feet of certified space in over 162 countries.
LEED v4 is the latest version. Credits are earned through real-time monitoring of energy (demand & consumption), water, and indoor air quality, in addition to other programs.

What is Measurement and Verification?
25
The role of Measurement and Verification (M&V) is to verify savings associated with energy conservation measures (ECMs) and strategies
M&V includes1: Determine baseline and estimate savings Develop the measurement and verification plan Conduct post-installation measurement and verification activities Conduct annual measurement and verification activities during the performance period

Access to critical data from equipment is usually done by walking around. That data is also sometimes available in a BMS. IoT can be used to make that data available remotely.
Examples: Detect faulty equipment before
equipment breaks Detect pipe freezing before
flooding happens Detect water leaks and get
alerted before expensive damage

How to monitor critical data in real-time?

A lot of legacy equipment can only be controlled manually and locally. IoT can turn that legacy equipment into connected devices.
IoT can also be used to feed new types of data into BMS for more efficient controls
Examples: Controls Fans in garage that are based on mechanical clocks or
temperature sensors Controls Lights that are based on mechanical clocks Control HVAC units that are not part of a BMS Create a BMS in the cloud to remotely control thermostats, etc.

Facility managers and engineers react to tenant complaints and work orders because they dont have data to be pro-active.
Examples: Fix Air Quality issues before
tenants realize conditions are changing
Provide information about space utilization
Know when trashes are almost full and need to be emptied

How to collect data to help with tenant comfort?

Distance
Looking at the data
Space temperature monitoring
Be alerted and react to abnormal temperature increase before tenants complain
Conclusion
Benefits of IoT* IoT is a simple and cost effective way to increase property value: through optimized
operations, better differentiation, and new sources of revenue * IoT pans across multiple domains: from helping with certifications to automation and
improved tenant happiness* IoT solutions are affordable so it is a perfect time to start adopting an IoT strategy in your
organization
41
How to get started?* Identify problems or tasks that consume a lot of your/your teams time* Read meters* Tenant work orders and complaints* Traveling to remote sites* etc.
* Find a solution that can address most of your issues, even if you only start by addressing one inefficiency
42
Implementation * Ideally, all of the devices need to be able to work together. * Importance of the Software/Service layer* IoT projects can be simple and can be implemented by your own building engineers or
technicians
