Johnson Controls recently unveiled the findings of its 2018 Energy Efficiency Indicator (EEI) survey that examined the current and planned investments and key drivers to improve energy efficiency and building systems integration in facilities.
Systems integration was identified as one of the top technologies expected to have the biggest impact on the implementation in smart buildings over the next five years, with respondents planning to invest in security, fire and life-safety integrations more so than any other systems integration in the next year.
As advanced, connected technologies drive the evolution of smart buildings, security and safety technologies are at the center of more intelligent strategies as they attribute to overall building operations and efficiencies.
SourceSecurity.com spoke with Johnson Controls, Building Solutions, North America, VP of Marketing, Hank Monaco, and Senior National Director of Municipal Infrastructure and Smart Cities, Lisa Brown, about the results of the study, smart technology investments and the benefits of a holistic building strategy that integrates security and fire and life-safety systems with core building systems.
Q: What is the most striking result from the survey, and what does it mean in the context of a building’s safety and security systems?
The results show an increased understanding about the value of integrating safety and security systems with other building systems
Hank Monaco: Investment in building system integration increased 23 percent in 2019 compared to 2018, the largest increase of any measure in the survey. When respondents were asked more specifically what systems they we planning to invest in over the next year, fire and life safety integration (61%) and security system integration (58%) were the top two priorities for organisations.
The results show an increased understanding about the value of integrating safety and security systems with other building systems to improve overall operations and bolster capabilities beyond the intended function of an individual system.
Q: The survey covers integration of fire, life safety and security systems as part of "smart building" systems. How do smarter buildings increase the effectiveness of security and life safety systems?
Hank Monaco: A true “smart building” integrates all building systems – security, fire and life-safety, HVAC, lighting etc. – to create a connected, digital infrastructure that enables individual technologies to be more intelligent and perform more advanced functions beyond what they can do on their own.
For example, when sensors and video surveillance are integrated with lighting systems, if abnormal activity is detected on the building premise, key stakeholders can be automatically alerted to increase emergency response time. With integrated video surveillance, they also gain the ability to access surveillance footage remotely to assess the situation.

Q: How can integrated security and life safety systems contribute to greater energy efficiency in a smart building environment?
Hank Monaco: Security, fire and life-safety systems can help to inform other building systems about how a facility is used, high-trafficked areas and the flow of occupants within a building. Integrated building solutions produce a myriad of data that can be leveraged to increase operational efficiencies.
From an energy efficiency standpoint, actionable insights are particularly useful for areas that are not frequently occupied or off-peak hours as you wouldn’t want to heat or cool an entire building for just one person coming in on the weekend.
When video surveillance is integrated with HVAC and lighting systems, it can monitor occupancy in a room or hallway. The video analytics can then control the dimming of lights and the temperature depending on occupant levels in a specific vicinity.
Similarly, when access control systems are integrated with these same systems, once a card is presented to the reader, it can signal the lights or HVAC system to turn on. In this example, systems integration can ultimately help enable energy savings in the long run.

Q: What other benefits of integration are there (beyond the core security and life safety functions)?
Hank Monaco: Beyond increased security, fire and life-safety functions, the benefits of systems integration include:
- Increased data and analytics to garner a holistic, streamlined understanding of how systems function and how to improve productivity
- Ability to track usage to increase efficiency and reduce operational costs
- Enhanced occupant experience and comfort
- Increased productivity and workflow to support business objectives
- Smart-ready, connected environment that can support future technology advancements
Q: What lesson or action point should a building owner/operator take from the survey? How can the owner of an existing building leverage the benefits of the smart building environment incrementally and absent a complete overhaul?
Lisa Brown: Johnson Controls Energy Efficiency Indicator found that 77% of organisations plan to make investments in energy efficiency and smarter building technology this year. This percentage demonstrates an increased understanding of the benefits of smart buildings and highlights the proactive efforts building owners are taking to adopt advanced technologies.
There is an increased understanding that buildings operate more effectively when different building systems are connected
As smart buildings continue to evolve, more facilities are beginning to explore opportunities to advance their own spaces. A complete overhaul of legacy systems is not necessary as small investments today can help position a facility to more easily adopt technologies at scale in the future.
As a first step, it’s important for building owners to conduct an assessment and establish a strategy that defines a comprehensive set of requirements and prioritises use-cases and implementations. From there, incremental investments and updates can be made over a realistic timeline.
Q: What is the ROI of smart buildings?
Lisa Brown: As demonstrated by our survey, there is an increased understanding that buildings operate more effectively when different building systems are connected. The advanced analytics and more streamlined data that is gathered through systems integration can provide the building-performance metrics to help better understand the return on investment (ROI) of the building systems.
This data is used to better understand the environment and make assessments and improvements overtime to increase efficiencies. Moreover, analytics and data provide valuable insights into where action is needed and what type of return can be expected from key investments.
