Smart Buildings & The Internet of Things (IoT)
The Internet of Things (IoT) is increasingly becoming the agent of change for how properties, both residential and commercial, are managed. Affordable technology is now available to monitor critical conditions in the property, instantaneously notifying the Property Manager of environmental changes that can seriously degrade the integrity and operating efficiency of the building.
Asset Management is the foundational level of a ‘Smart Building’ infrastructure, and the good news is that what was once an expensive proposition has now reached a price point where the return on investment for the property owner may be immediate.
A Smart Building architectural design can go well beyond asset management, with convenience features such as automated lighting, appliance control and dynamic HVAC configurations. Real-time monitoring and management of building parameters such as energy usage, access control, and alarm conditions, all contribute to improved operating efficiency for the property. An inter-connected network of IoT sensors, aggregating data into a cloud-based management system, yields a user-friendly, remotely-accessible property management tool for the Property Manager.
What is a Smart Building?
At its core, a Smart Building creates a safer, more responsive environment for residents, employees and the property owner. Ubiquitous sensors placed throughout the building monitor key indicators within the property. By continuously monitoring environmental conditions such as temperature, humidity, water leakage and carbon monoxide levels, potentially catastrophic problems are immediately identified, resulting in a safer space for the occupants, and a protected asset for the property owner. Protecting the building and its occupants should be priority one for any Smart Building.
With a smart foundation in place to address building safety, IoT technology can also be employed to enhance the operating efficiency of the property, primarily through energy management. With smart meters, all utilities can be continuously monitored. Data analytics applied to the energy usage data collected over time; i.e., trend analysis, will reveal a deterioration in the performance of the energy systems.
Installing IoT-connected load shedding switches allows the utility to perform demand management, in exchange for a lower energy rate.
A Multi Dwelling Unit (MDU) property is an ideal candidate for a smart infrastructure, providing numerous management features, which facilitate the everyday responsibilities of the Property Manager. A single screen of a tablet app graphically displays the temperature and other environmental conditions of an entire floor. Using the same tablet app, the Property Manager can place an unoccupied living unit in the “vacant” mode, automatically arming the door entry and motion detection sensors, and setting back the temperature.
Residents who enable a beaconing feature on their smartphone, or choose to wear a panic button pendant, can be immediately located in a building, an important feature for aging in place and assisted living facilities.
Now we come to the futuristic lifestyle, so commonly associated in popular culture with a Smart Building. With the interconnection of property sensors, human sensors and appliance control, myriad convenience features can be realized. A motion detector in the master bedroom turns on the heated flooring in the master bathroom, but only during typical wake-up hours in the morning. Sensing that you’ve arrived at home at the end of a work day, the system turns on the TV to your favorite news channel. Hundreds of “if this, then that” scenarios can be envisioned and programmed into the Smart Building system.
Lastly, a Smart Building enables an unprecedented opportunity for academic research into human behavioral analysis on a broad scale. The sensors imbedded in a smart building infrastructure collect data on everyday human activities, sending the data (in anonymous form to protect the privacy of individuals) to a data analytics engine for analysis by private and public enterprises. The insights gleaned from this research holds the promise of societal advancements in a wide array of disciplines, including urban planning, telemedicine, and human factors and ergonomics, ultimately leading us to a world in which Smart Cities are commonplace.
How Does IoT Work:
There are three functional layers in the IoT system model: Sensing, Aggregation, and Services. The Sensing layer can be segmented into two sub-classes: property sensors and human sensors.
Property sensors are embedded in the building infrastructure to monitor key environmental indicators such as air quality, temperature and humidity, to generate security alerts such as door open/close and motion detection, to measure energy consumption, and to facilitate location awareness.
Human sensors are associated with human activity, and are typically worn or carried; examples are wearable wrist bands, panic button pendants, and even a mobile phone. In a Smart Building, the combination of fixed property sensors and mobile human sensors produces a tremendous amount of data for the system to interpret and act upon.
It is advisable to use wired sensors whenever possible for fixed property sensors, to circumvent the need for periodic battery replacement. However, wireless sensors powered by a battery are the practical choice for human sensors.
Data from the sensors are collected at the Aggregation layer; this typically takes the form of an IoT Gateway or Hub. For example, in an MDU application, each living unit may have an IoT Gateway installed as part of the building infrastructure, to collect data from the wired and wireless sensors in the living unit. The intelligence associated with interpreting and acting upon the collected data may reside in the gateway, or the gateway’s role may be limited to only collecting the data and passing it up to the next level. In many cases, a hybrid approach is the best solution, in which some limited functionality is performed locally within the gateway, while the majority of the system intelligence is at the next level.
That next level is the Services layer, consisting of management software residing in the cloud or on an on-property computer. Here, at one central location, is the repository for all the collected data. The Services layer interprets the data for the purpose of passive monitoring, real-time control, and “if this, then that” functionality. And, performing data analytics on the accumulated data produces insights for a multitude of business, lifestyle and societal applications.
Another component of the Services layer is the User Interface (UI). The consumers of the IoT data, whether they be the Property Manager, resident, security personnel, etc., access and view the information reported by the IoT system with a UI. The UI can take many forms: a smartphone, smartwatch, tablet PC, a laptop, a smart TV, a voice control device such as the Amazon Echo, or a management console in a monitoring center. Certain UI types are more appropriate for different consumers; for example, a smartphone app may be most convenient for a resident, while the larger screen of a tablet PC is more suitable for a Property Manager.
