IoT Applications

What does Internet of Things mean?

IoT definition is an evolving concept

A proposed development of the Internet where everyday objects have network

connectivity, allowing them to send and receive data

Physical Device

Suite of technologies and applications that equip devices

Instant data analysis and, ideally, smart action1.

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

IoT can augment a BMS or even can act as a 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

IoT Device

How to monitor critical data in real-time?

Prevent pipe freezing

Thermistor Probe

Make sure purge system is working

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?

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
