Maintaining the Benefits ‣ Reality – Systems degrade over time ‣ Recognizing and maintaining the benefits takes a complete solution Connected building outcomes, enabled by analytics, visualization and service Facility use changes Sensor recalibration NOT performed Schedule overrides don’t get reset Alarms NOT set up to support staff Deferred maintenance Set-points get permanently changed Investments in energy efficiency systems Make conditions visible vs. inefficiencies going unnoticed Addressing issues - 16% ave. annual savings! (US DOE. LBNLStudy ) TIME Results through connected solutions! Building Efficiency- + Connecting equipment, systems, buildings…
- 12. Be Informed – Technical ‣ Standards still in flux with IoT in buildings ‣ Too many standards - no “standard” way of addressing interoperability ‣ Integration of disparate systems ‣ Lots of legacy communication protocols ‣ Fast-changing technology, lots of new tools and new skills, new standards Be prepared to make the most of IoT benefits…
- 13. Attention to Security ‣ IoT security – Major customer concern ‣ Needs to be designed into the system solution ‣ Impacts data collection and storage ‣ Requires collaboration between operations and IT teams ‣ Requires proper application hygiene Security is a business issue – and needs to be a top priority
- 14. Educate Yourself and Partner for Success ‣ Do your homework - understand the risk in the target application ‣ Update legacy systems to help ensure IT security ‣ Understand integration needs and capabilities of systems that connect with yours ‣ Partner for success. Leverage experts to bring solutions together ‣ Engage key stakeholders (internal and external) to raise awareness of both the opportunities and the risks associated with connectivity Overcome the challenges…

Editor's Notes
- - Good afternoon! - Thank you for the kind introduction. It’s a pleasure to be here to talk about Trane’s Connected Building Journey - Raise your if you are a fan of the San Diego weather. Since I live in Minneapolis I try to tell myself I love the weather. I know it’s only 20 F in MN, but the wind-chill makes it feel like 0.
- - In the next 25 minutes I will touch on a little history of HVAC building systems to provide a frame of reference - IoT enabled technology changes that are transforming building systems. - How we got started on the connected building journey - Example of how the transformation is effecting customer business outcomes - Common challenges we faced that are good to keep in mind when making similar transformations in your industries.
- 1913 - James & Reuben founded Trane in La Crosse, WI 1973 – Oil Embargo drove up energy prices, and created demand for energy conservation (EMS was born) 1978 – Trane purchased controls company in Minneapolis to develop building management system 1980s – Start of HVAC system integration, however many proprietary protocols 1990s – Movement to open communication protocols (like BACnet and LonWorks) 2000s – Movement to remote IP connectivity – This includes modums to access BMS devices and pull data Present – Advances in web based systems, wireless, cloud, mobile, analytics, visualization, etc… - This includes data being pushed, with remote access, analytics,, and advanced applications to support turning data into business value. -- Throughout the history of Trane, it should be pointed out that the service relationship was and continues to be the foundation
- - So what’s changing that enables the connected building transformation? This page helps illustration a combination of recent connected building technology innovations that are improving business results. - Advanced web-based controls with open standard protocols, mobile access, and pre-packaged applications – makes it quick and easy to collect and act on data - Cloud enabled remote monitoring for Intelligent Services with diagnostics, and predictive analytics – Makes it easier to combine data from many sources, run advanced analytics, and leverage centralized expertise to turn raw data into insights and actions. - Improved visualization tailored to specific roles to drive action and link to business outcomes - Finally, there is a “digital” transformation of business processes taking place to get closer to customers and align building system solutions with evolving business needs.
- Once we have a clearly defined strategy that identifies the business opportunities and benefits, the data needs become clear, which then drives the specific tactics. What data is needed, and the best source of data What databases need to be integrated Who owns the data and how best to leverage partners How to display the data to visualize what information and take action
- Energy efficient movie theaters that keep guests comfortable
- Steel fermentation vats on brewer factory
- Primary customer value comes from traditional benefits associated with comfort, energy savings and operational efficiency, however, in this example new benefits are being delivered in the areas of customer experience and increased sales FYI - Ingersoll Rand is engaged in project connecting all our plants….Walking the talk – stayed tuned….Connected building approach – bringing our own plants up to speed right now to phase them in.
- A new building that is properly commissioned will operate “as designed” and provides the benefits expected… - Unfortunately, the reality is systems degrade over time for a number of reasons. US Dep of Energy did a study of 600 buildings and found significant inefficiencies. Common causes of degradation result from Facility Use changes (reconfigured), Sensors not maintained, Alarms not set up or ignored, Schedule overrides and set points are changed permanently vs. temp Even found devices were missing like temperature sensors needed for proper control, dampers or valves for adjustments, etc. - Getting the benefits over time is supported by the connected buildings, but requires a complete life-cycle solution Once you invest in the right equipment and systems, they need to be connected, monitored, analyzed, and presented in a way that enables action (which quite often requires feet on the street). – Components fail, dampers get stuck, filters & coils need cleaning, and occasionally a critters chew through ductwork, die in vents, or get tangled up in the wrong place.
- Still the wild west with respect to IoT in buildings - Too many standards - no “standard” way of addressing integration (BACnet, LonTalk, Modbus, Zigbee, etc.) - Integration of disparate systems (HVAC, Lighting, Security, Meters, Grid,…) - legacy communication protocols (mostly proprietary supplier specific protocols) - fast changing technology, lots of new tools, and new skills, Image: Trane DAM image: Building3
- IoT Security – Major concern of customers & suppliers – could be an entire presentation, to stay on track I’ll only highlight a few areas 1- Needs to be thought of and designed as a system solution – not just the product… - “secure by design” involves the complete product life-cycle and associated governance - Upfront security requirements/standards, software architectural risk assessments, code reviews, verification & penetration testing, installation and access control, updates to defend against evolving threats and more... - Impacts data collected & how it is stored – Again gets at what is needed to deliver business value vs. what we can store, and who has access to the data that is available. - Operations and IT need to collaborate – this is changing the role of facility managers who traditionally focus on equipment vs. IT. - Proper application hygiene is critical – Awareness is still lacking, -- an analogy would be the best deadbolt in the world doesn’t matter if you hang the keys on the door knob. Of course we are trying make it fool proof and eliminate keys, but application configuration matters. - It is a business issue, and needs to be a priority – Agree on standards, and prioritize the work to drive actions.
