Buildings are expensive to maintain and still they are constantly under-performing. They waste energy, contribute to excessive CO2 emissions, and fail to consistently deliver quality comfort conditions. Manual monitoring is still commonplace requiring enough experienced staff to monitor multiple properties continuously. The International Facility Management Association (IFMA) estimates that with active controls and IoT-enabled technology, data-driven facilities can expect a 50 percent increase in cost efficiency, including energy, maintenance and other recurring costs.
Becoming data-driven starts with situational awareness, knowing the status right now and when something happens. Then, comes the benefits from running operations remotely that adapts, automate, optimize and enable premium services.
requires access to data
With IoT sensors, you can acquire a trove of new useful data. For instance, the temperature in all spaces, water usage, vacancies, and more. Just adding one new set of data can make a huge difference. See this example of how to combining different sensor data to acquire essential insights into the usage of a classroom.
Operations with IoT and legacy systems is a complex environment, for which Sensative have developed Yggio to integrate and manage it all.
You don’t have to start with a comprehensive project involving all systems in many properties across the nation to realize a fast payback. Your first IoT project can and should be small, allowing you to learn from the experience of your implementation. Then build on your success.
A Sensative customer measure temperature in all apartments and shared spaces with Strips LoRa MS-H sensors to gain energy efficiency insights from their extensive property portfolio. The data is consolidated using Yggio.
The expected result is 4% savings on energy cost per 1˚C lowered temperature, by just manually adjust heating based on this new knowledge.

water damage and mold in the U.S. alone
You get an alert that there is water under the sink in one of your tenant’s apartments. Previously, you would (hopefully) receive a call from the tenant once they’ve discovered the leak, but often there is already considerable damage done. Now, since you have installed water leak sensors under all sinks, the alarm reaches your customer service, and you can dispatch maintenance immediately.
Of course, it would have been even better to have the possibility to turn off the water remotely to prevent further damages before the maintenance staff can repair it.
A 10-year study shows that LEED certified properties enjoy an average of 3.7% rent premium and a 4% gain in occupancy. This translates into 8 to 10% increase in asset value over comparable non-certified properties.
LEED certification holds organisations accountable to meeting sustainability standards about building materials, water savings, energy efficiency, waste management and overall sustainable development.
This is an example of the certifications and regulations that are changing the way we think about how buildings and communities are planned, maintained, and operated.
IoT provides the data needed for accountability.
acting on data
Save money and improve service with remote operations
- Identify problems sooner and fix them earlier
- Reduce energy consumption
- Optimize and reduce waste
- Improve customer services
Remote multi-site operations immediately deliver payback when you avoid having to send a person to see what’s going on or act on a maintenance call. Fewer staff can monitor more buildings, decreasing the cost of staff traveling between buildings.
You will also have actionable data in real-time, not only when data is recorded on-site, reducing risks and improving performance.
The next step is immediate action through remote control. Either by interfacing existing control systems remotely or by installing new remote control equipment.
A call to customer services can often be managed directly, not having to wait for a technician to arrive at the site.
Integration is fundamental for creating efficient remote operations, a common interface to everything. When you automate you often need to be able to take data from one system or sensor from one vendor and have it trigger an action in a different system. For instance, a water leak sensor must be able to trigger a remote valve, even if they are from different suppliers.
Example: meeting room with smart ventilation
High levels of CO2 in a room makes people tired and reduces productivity. The easy solution would be to exaggerate ventilation, but that comes at a cost of higher energy consumption in the HVAC system. To optimize ventilation, the airflow should be balanced against the number of people present in the room.
One exciting solution comes from Sensative’s partner Axis Communications. By mounting a camera equipped with People Counter, the entry or exit of a person is signaled to Yggio, and through Yggio’s Rules Engine the signal is converted into a pre-programmed control command that can be sent to the room’s HVAC controller.
As an extra feature, the system can turn off lighting when the last person leaves the room.
The International Facility Management Association (IFMA) estimates that IoT capabilities allow building managers to implement predictive maintenance and analytics technology, allowing facilities to save up to 20 percent per year on maintenance and energy costs
In the life cycle of a building, maintenance costs largely exceed the construction costs.
IoT will drastically reduce operating and maintenance costs thanks to all the new actionable data. Sensors placed on equipment can monitor status that can be analyzed and used for planning maintenance to prevent failure and downtime. As a rule of thumb, predictive maintenance is 3 to 9 times cheaper than waiting for when the damage has already occurred.
Ventilation fan motors typically operate for 24 hours a day in a commercial building, and its health can be monitored with IoT sensors. A heat sensor that detects a slight rise in engine temperature or a vibration sensor that detects increased vibrations, could be an indication of an emerging problem. Order spare parts and schedule maintenance at the most convenient time before a more prominent problem emerges.
Don't forget the IoT equipment
When introducing the new IoT devices you should also consider the maintenance cost of these devices. Most sensors are battery-driven and will have a life span that must be taken into account. A long battery life makes a huge difference.
Batteries are cheap, replacing them is not. Sensative’s sensor batteries last up to 10 years without maintenance.
E.g.: 1,000 sensors * US$150 per battery replacement (battery and labor costs) = US$150,000
A normal battery life span can be 3 years, so a 10-year life span means you don’t have to replace the battery 3 times = US$450,000 in savings.
