CABA PRESIDENT & CEO’S MESSAGE Ron Zimmer, CAE During the 27 year history of CABA, home automation and intelligent building technology has evolved similarly to other technology advancements in the automotive, aviation, or IT industries.
The earliest inventions and patents (i.e., X10, Modbus, etc.), laid the foundation for many other protocols, standards
and innovations. These technologies created opportunities for many organizations, some with great products and services. However, the market wasn’t ready for mass adoption.
Today, we have a “tsunami” of new technologies. The maturation of IP has helped create an “Internet of Things”
(IoT), that is projected to be as pervasive as electricity. However, a combination of factors is creating a “perfect storm” for organizations that provide the right product or service to the right business partner or stakeholder group. Advancements in wireless technology are finally allowing end-users to deal with existing infrastructure that allows for a less costly retrofit. We are finally observing a true effort to deal with interoperability issues, through organizations that are driving open standards and truly functional middleware.
There are too many to list, but witness the great reductions in energy usage through energy management sys-
tems, LED lighting and integration of renewables. Wait until batteries for homes and buildings become affordable and there will be a quantum leap in the use of renewable technologies. With a growing elderly population and an explosion in healthcare costs, telemedicine and telehealth can be one of the answers to impede these rising costs for employers, insurance companies and governments. We are just seeing the first wave of wearables, smart TVs and smart cars, which will all have projected adoption rates that will set mass adoption records compared to older technology.
Unfortunately, along with all the positives come the disadvantages of interoperable devices in the new connected
homes and intelligent buildings IoT ecosystems. Cybersecurity is the nasty side of this business due to people, organizations and countries that are willing to exploit the weakness in deployed systems. Remember that technology that was installed decades ago has in some cases been cobbled together with newer technology, which in many cases are wide open for hacking and exploitation. Unfortunately it will take more headlines in the Wall Street Journal before more organizations realize that the threats are very real. The CABA Board and various CABA Councils have recognized that cybersecurity needs to be understood not only the OEMs and service providers, but also every group in the ecosystem, right down to the end-user.
Therefore, at the April 14 CABA Board meeting two new Landmark Research Projects were launched and announced
at the CABA Intelligent Buildings & Digital Home Forum. CABA members will be funding the CABA “Intelligent Buildings and Cybersecurity” and the CABA “Cybersecurity and the Connected Home” research projects. Go to www.CABA. org for more information or contact the CABA office if these projects interest you.
Just remember…CABA has a plan and it includes you!

In a central hub solution, the various devices associated with the smart home are controlled by a central device, and this then can extend outwards to access a variety of secondary smart home features. Such a hub can also be managed itself by a more accessible, personal device such as smartphone or tablet. In the direct control view of the consumer IoT ecosystem each device has its own embedded protocols and capabilities, and can directly interact with other node devices. One significant factor that governs both the development of the wider market and ecosystem but also governs which of these topologies wins out, relates to issues around connectivity in the home. The consumer survey responses from this report emphasized how important interoperability is, and also demonstrated that consumers expect to some extent to be able to purchase connected devices from a range of suppliers and for these to work together and be controlled together. CABA members that participated in CABA’s Connected Consumer Roadmap project included: Alarm.com, Arizona Public Service Company, Arrayent Inc., Hydro One Networks, Hydro-Québec, IEEE, Intel Corporation, Intermatic, Panasonic, Pella Corporation, Philips, Qualcomm Incorporated, Schneider Electric, SecurTek Monitoring Solutions, Southern California Edison Company, Support.com, TELUS and UPnP Forum.

LARGE BUILDING AUTOMATION Building Operations: Opportunities and Issue Jim Sinopoli, PE, RCDD notes human resource and technology opportunities and challenges will arise in the facility management sector. Sizable buildings are now conceived, planned, financed, designed and constructed in a relatively short number of years. However, the cost of operating a building are generally measured in decades and is typically 65-80 percent of the total lifecycle of the building. There are capital costs to construct a building, but about 75 percent of the total lifecycle cost of a building is in building operation and maintenance. So the real issues with building operations for the owner is the duration of the building and the ongoing operating costs; essentially time and money. Oftentimes building owners involved in designing and constructing a new facility are totally focused on the initial capital budget and investment in the facility. While it’s a legitimate concern the design and capital spent needs to focus on long term operations, answering the question of what’s the best use of capital to operate the building over the long haul. Building operations span a very broad spectrum of issues. It’s not just hot or cold calls from occupants. There are many larger issues dealing with safety, profitability, energy, and management. The facility management group is expected to have the expertise and capabilities to manage and execute a variety of tasks and responsibilities. The International Facility Management Association (IFMA) has identified eleven core competencies of facility management: Communication – Communication plans and processes for both internal and external stakeholders Emergency Preparedness and Business Continuity – Emergency and risk management plans and procedures

LARGE BUILDING AUTOMATION
Technology Technology and innovation have always been part of the building industry going back to the last century with the invention of electricity distribution, elevators, and construction cranes, power tools, etc. Today’s innovative technology is not just new devices or equipment, it’s a relentless penetration of information and communications technology and a flood of innovative systems and equipment. Given our global society’s habituation to computers and smartphones, people and building occupants now expect technology laden buildings. The larger background for technology in buildings includes among other things smart cities, wearable technologies, big data, apps, analytics, and the Internet of Things. While standard IT networks have been a staple in buildings since the early 1980s, IT has now penetrated further. We have standard building communications protocols such as BACnet/IP, building management systems which are based on IT servers, using an operating system, and having IP addresses. There are ANSI standards for using IT cable for BAS systems and a host of other systems including IT-based lighting systems using Power over Ethernet (POE), the use of Wi-Fi in BAS controllers, IT-based access control, digital video surveillance, mass notification, DAS systems, paging, and plug load management systems. In the last four to five years, astute building owners and facility managers have embraced some IT functions such as data management and the use of analytic software applications for some of the building control systems. The results have been overwhelmingly positive. The industry may have been late to data management and mining but there’s now an awareness that there is tremendous value in data management and that it should be treated as an asset. During the design and construction of a building data will be generated; it is in the operations of the building that data not only will be generated but also consumed. Data management is required during every building phase: design, construction and operations. A key organizational element is to elevate the importance of data management by assigning a distinct job description with the responsibility and authority to manage all the facility data. In new construction we typically have two to three people tasked with managing various data; the LEED consultant, the BIM consultant and the architect. The use of BIM as a significant data management tool for new construction
8
provides the framework and starts the building on the right path. The BIM COBie data can be exported into to some of the facility management systems such as asset management and preventative maintenance and assist in getting the building operational quicker. The use of analytic software applications have demonstrated positive measurable results. A study by Lawrence Berkley Labs titled “Automated Continuous Commissioning of Commercial Buildings” in 2011, indicated 30 percent reduction in building total energy consumption and related costs over the baseline; and 30 percent reduction in building peak demand and CO2 emissions On top of that are operational savings related to such an application increasing personnel efficiency and effectiveness; facility engineers and technicians being more quickly alerted to a fault in a building system, provided improved information on potential system remedies, and monetizing faults to indicate the wasted energy. Given their track record, analytic applications have been successfully used in lighting systems, electrical distribution, conveyance equipment, data centers, etc. Human Factors
Innovative technology is disruptive. For building operations, technology disrupts the organization as well as the individual personnel requirements. Organizationally, many companies or building owners have an IT department as well as a facility management department. Potentially there are issues regarding the systems managed by facility management (HVAC, electrical, lighting, etc.) that have IT aspects; which begs the question, which department is responsible for responding and addressing the issues? An example could be a network controller in a building automation system that connects directly to an IT network; facility management may “own” the controller but the IT department may “own” the network. If the two departments have a good relationship any issue can be addressed together. If not, operations may be impacted. Some building owners have dealt with this by either bringing on some IT technicians within the facility management department, so they can self-perform or have created a “Systems Engineering” department combining both facility and IT. People are our greatest asset and conversely our weakest link. Yet, the larger picture related to building operations and Continues on page 20

RESEARCH VIEWPOINTS
Building Energy Management Systems Market Continues Expansion By Casey Talon
It is understood that our buildings are inefficient. The energy waste generated by the status quo represents a significant source of greenhouse gas emissions and potential laundry list of investments for facility improvements. The problem is evident, but the solution has been hazy due to limited regulatory mandate and corporate budget priorities. In the last few years, however, Building Energy Management Systems (BEMSs) have emerged as a cost-effective solution to help drive a shift in how run our commercial buildings. Navigant Research has been tracking the market and our new report, Building Energy Management Systems, sheds more light the business case for investment and the impact of BEMS adoption. Today, it’s all about data, and Building Energy Management Systems (BEMSs) are translating more and more data into action. We are seeing a transition from showcase pilots to broadening implementation across business segments. Microsoft, for example, has partnered with Iconics, and is helping take the lessons learned from its campus showcase, marketed as 88 Acres, to market with a new deployment in Washington’s King County. County buildings will be able to leverage the newly branded Smart Building Energy Tracking System. Carnegie Mellon University has partnered with IBM to deploy the new Building Management Center to leverage data across its campus to target energy cost savings of an estimated $2 million annually. BEMSs work for tech companies, government, and higher education, and are gaining traction across the building sector. In fact, our research indicates there is a growing business case for investment in BEMS from commercial real estate to fast-serve restaurant chains. Defining the Solution
an evolution in the approach to facilities and operations management. These solutions are defined by the convergence of traditional and innovative hardware, software, and services to bolster the control and automation of building systems and manual procedures. Our research indicates that in the last five years, investment in BEMSs is accelerating as demand increases for data-driven tools to support business decisions. Executives require transparency in how investments impact their business, and at the same time there is a growing understanding of how energy consumption can be a tangible metric of business performance. This is because energy efficiency improvements generate direct and quantifiable impacts on facility operations and maintenance, capital expenditures, and most clearly, utility bills. The core benefit of a BEMS investment is the transparency and accountability these solutions offer to corporate management. The term BEMS is applied to a broad set of solutions that have emerged in response to the demand for cost-effective, data-driven solutions to improve the energy efficiency of building operations. These products utilize data from traditional control and automation systems, smart meter interval electricity consumption data, supplemental submeters and advanced sensors, and/or other business intelligence offerings. Industry stakeholders report diverging perspectives on the precise definition of BEMSs. Navigant Research provides the following definition of BEMSs to clarify the boundary around technologies and services that shape this next generation in energy management solutions: “IT-based solutions that extend the capabilities of sensing, control, and automation hardware to direct both automated and manual improvements to system operations.”

First and foremost, in today’s state of the market, BEMS hone in on energy efficiency in one of two ways: via focused improvements in HVAC, lighting, plug loads, or fire and security systems; or via the integrated management of multiple systems. The reality is that BEMSs hold the promise of integrated, proactive, real-time system optimization, but most deployments target mechanical improvements, where the majority of energy demand stems from in most commercial building environments. The future, however, promises deployment of BEMSs that enable buildings to become integrated and responsive resources that support reliability and resiliency. What’s important is that even in these early days of the market, BEMSs change the energy management paradigm to deliver strategic and holistic management of facilities and equipment. A Maturing Market The BEMS market has emerged through a combination of efforts from large, international building automation and controls incumbents, IT vendors, professional service firms, and technology startups. The diverse vendor landscape reflects the universe of customer demands in this early adopter marketplace. The variety of BEMS offerings corresponds to the range in customer demands. What makes a valuable BEMS is defined by the customer’s position in an
10
organization and a segment of the economy. The BEMS solution complexity not only reflects the needs of a particular customer, but also the systems that are installed at any particular customer site. There are huge variances in the building stock in terms of infrastructure from very large facilities with complex building automation systems to small facilities without any controls. Even within these two sides of the spectrum there can be significant difference between facilities. Two very large facilities, for example, may have traditional controls, but one may be old and underutilized while the other is fully maintained and deployed. These circumstances will define the appropriate BEMS or the level of investment needed to implement more sophisticated solutions. Ultimately BEMS need data, and customers must determine the right solution for their business needs. This question can be daunting and there is a lot of room for market education. As a result, in these early years, there is low-hanging fruit just in bringing an understanding of what is happening within a facility’s walls. Less sophisticated solutions can deliver significant benefits to customers early on the path toward comprehensive and strategic energy management. For example, a corporate real estate executive may benefit from a visualization and reporting offering that analyzes simple energy billing data as a first step in developing a

baseline of the portfolio energy consumption. This investment can deliver significant return on investment (ROI) by helping to target specific buildings that can benefit from low- and no-cost energy conservation measures (ECMs) such as changing heating, ventilation, and air conditioning (HVAC) system setpoints or schedules. As customer needs become more sophisticated, they can leverage more sophisticated BEMSs. The result of this myriad of customer demand and building conditions is a spectrum of BEMSs offerings in four classes: Visualization and Reporting, Fault Detection and Diagnostics, Predictive Maintenance and Continuous Improvement, and Optimization. The figure below illustrates the range of offering in each of the four classes that can deliver benefits to address very specific customer pain points. While there is huge room for customer education, the market for BEMSs is starting to mature as customers begin to recognize the business value of investment. Each year, more customers understand the benefits of BEMS investment as demonstrations and installations in the market provide proof of concept to help accelerate adoption. The Business Case
Over the last few years, the BEMS market has experienced
CABA iHomes and Buildings Summer 2015
continued growth as energy efficiency has become a higher priority among businesses and governments and as these potential customers have demonstrated a broader understanding of the business value of BEMSs. The varied global economic, regulatory, and corporate market drivers signal continued growth in the BEMS market. Corporate social responsibility and climate change commitments are important drivers for large corporations at the international scale, but there are also distinct policy and economic drivers associated with the major geographies that affect BEMS market growth expectations. Today, customers need to see the economic impact of their energy efficiency investments, and BEMS are a valuable tool that provides transparency and insight into how operational changes, capital investments, and even behavioral changes affect the bottom line. How Much Investment is Underway
The market for BEMSs is growing across global regions and customer segments. The drivers, barriers, and technology design may differ across geographic and customer segments, but overall, the market dynamics worldwide continue to signal increasing revenue for BEMS providers through 2024. According to Navigant Research, the global BEMS market is expected to grow from $2.4 billion in 2015 to $10.8

RESEARCH VIEWPOINTS
billion in 2024 at a CAGR of 18.2 percent. The fastest-growing regional market is projected to be Asia Pacific with an estimated CAGR of 19 percent. Yet, the BEMS markets in the other major regions are also expected to grow at a rapid pace. Navigant Research expects BEMS revenue to grow at 2015–2024 CAGRs of 18.9 percent in Europe and 16.8 percent in North America. Market growth will be driven by regional policies mandating energy efficiency improvements, primarily pushed by climate change mitigation goals. Growing customer awareness of the economic benefits of investment in BEMSs will be the significant driver for investment in the near term. Despite political uncertainty, Navigant Research projects sustained, significant growth through 2024 because of the combination of the business case for investment and the momentum in bottoms-up (cities and regional) regulatory policies. What does it all mean?
Looking ahead, the BEMS market will continue to evolve as customer demands become more sophisticated and adoption becomes more widespread. Regional markets will likely mature at different rates, reflecting broader macroeconomic and policy conditions. Developments in specific localities, such as the new smart cities in India, will begin
to demonstrate the logistical and economic realities of implementing BEMSs among rapid urbanization. Such early case studies will have an impact on the future of BEMSs in developing regions worldwide. We expect that solutions for smaller facilities will see rapid growth in adoption as the pipeline of pilots demonstrates the economic impacts of energy efficiency and maintenance optimization across their portfolios. New BEMS offerings will continue to emerge from the lighting industry because of the opportunity to utilize cost-effective monitoring devices originating in lighting controls for more comprehensive energy management strategies. BEMS solutions that quantify the ROI on ECMs will succeed in the near term because of the current customer focus on energy cost savings. Solutions that offer the capabilities for integration across equipment types and incorporate algorithms for predictive maintenance and enable automated system improvements will generate the most business value in the mid-term as the market continues to mature.

air-conditioning). There are better ways of doing things electrically.
Kasier, we seldom have the choice of individualized options anymore. When a house is concerned, things
Integration and flexibility
are quite different.
Newer technologies lift electrical installation to greater heights. Because of their integration possibilities, they are capable of letting multiple subsystems in the home communicate with each other. This has opened up numerous possibilities that increase the residents’ comfort level, offering more user-friendliness, better communications possibilities, greater safety and lower energy consumption. Thanks to the flexibility of such systems, it is usually easy to make changes. The functions of switches and buttons can be changed through software. The installation can be adjusted to meet the residents’ changing needs at any time.
Residents have long benefited from traditional electrical home installations. Various devices making our lives easier, along with electric lighting, are generally taken for granted. Still, the traditional electrical installation with its various sockets, switches and lights is on its way out. The last two decades have seen many new technologies for electrical installations find their way into our homes in order to deal with the limitations of the traditional installation. History
Electricity inside the home was not always so easy. Not that long ago it was considered normal to use candles for lighting and manually spin the wheel to get the laundry barrel moving. Historically, electricity is a relatively young technology. Most people only had electricity inside their homes in the first half of the twentieth century. Interior spaces featured one light and one switch with a socket underneath. This increased as the number of electrical appliances grew, especially in the kitchen. In addition, new technologies such as dimming, time switches and motion sensors became widespread. Nevertheless, the electrical installation’s basic structure remained the same, and this has resulted in important disadvantages. Changeability or flexibility is non-existent. There is no communication between the traditional electrical installation and other subsystems inside the home (e.g., heating, door communications, alarm systems, audio,

Your car and your home, what is the difference? You cannot live in your car, nor can you go from point A to point B with your home. Chances are that you have more integrated technology in your car than in your home. To cite just a few examples, consider the windscreen wipers that turn on automatically as soon as it starts raining, or the headlights that switch on automatically when it gets dark. Finally yet importantly, the overhead light that switches on when you turn off the engine and turns itself off when you get out the car and lock the door. If you have a late model car, it is almost certain you have an onboard computer that lets you consult all types of information (e.g. current and average consumption, or miles to drive until the next petrol stop). You probably cannot do without cruise control, electrical windows, automatic doors, GPS, audio, climate control and various other creature comforts. All are widely available because they make life inside your car far more easy.
13
HOME SYSTEMS
Strangely, our way of thinking is far more conservative when it concerns the home. Some sockets and lights will still do in most cases. We have already welcomed digital TV inside our homes: we did not have a choice, because soon no TV stations will broadcast in analogue. We use our smartphones and their many awesome apps on a daily basis. However, using a remote or an app to operate the lights in our living room from the couch is too much. What is the difference between your home and your car?
When you’re walking over to your car, you unlock the car from a distance with what we will call your car’s access control system. A light will switch on automatically so that you can easily find the ignition in the dark. Once the engine is started (with a key or a badge), the light slowly goes out. When it is dark, the headlights and taillights will switch on automatically. The GPS will guide you to your destination without you having to take out a map. While driving, you can use the handles around or the buttons clustered on the steering wheel to consult your fuel consumption, the mileage left before you need to stop to refuel or recharge, determine your average speed, and other pertinent information available from your on-board computer. When traffic is light, you may want to use your cruise control. On top of that, your car probably also has a radio, a CD player, the possibility to listen to MP3 music files from a USB memory stick, and a Bluetooth connection to your smartphone, all of which can be controlled from the touchscreen or with your voice or hands on the wheel. The home with a traditional installation
The majority of European homes are still equipped with a traditional electrical installation. Besides a couple of power sockets, you have one or more switches for each light. Sometimes there is also a smoke detector, but that is probably operated by small replaceable batteries that you have to replace from time to time and not connected to the mains. Functionality is very limited. The flexibility of such traditional installations is nil. These installations are not capable of evolving with the changing needs of the residents, or with innovative and modern technologies. All of your electrical appliances and systems work, but separately from each other. There is no bilateral communication. They may work well but they standalone.
14
The home with an integrated home system
Homes are increasingly equipped with an integrated home system. Besides the traditional electrical components such as switches, there are also electronic components and software integrated as well to operate and control the home. Actions can be carried out even from a distance when desired. The technology has been around for more than 25 years and enables the integration of various standalone systems. An example: When you come home in your car, you open the garage door from inside the car with your remote control. When it is dark, the integrated home system will automatically switch on the lights in, for instance, the entry or kitchen. In addition, the heating or air conditioning receives a signal to switch to comfort mode. These are merely some of the many possible functionalities that can be adapted to your needs at any time. Car vs home
We tend to drive our car for several years (four to 10 years). Upon purchase, the car is already equipped with lots of functionalities and possibilities. We seldom have the choice of individualized options anymore. Today, everything is more or less standard with only one or two option packages available. Hence, upon purchase, the car is almost certainly equipped with the latest functionalities and possibilities. When a house is concerned, things are quite different. When buying or building a house, we generally have the intent to live there for 20 to 25 years. The electrical installation is one of the main building blocks of a house, as are the bricks and the roof. It is of utmost importance that we immediately opt for a modern electrical installation with functionalities and flexibility. Switching from a traditional installation to an integrated home system after a few years will be far more expensive than simply opting immediately for integrated home system. In the latter case, you are set for at least a few decades to enjoy the current and future potential of these systems. Tune your home as you do your car.

KEN WACKS’ PERSPECTIVES
Multimedia Networks in Buildings By Ken Wacks
Multimedia is being integrated into a diversity of commercial settings, ranging from corporate offices to educational facilities to transportation to government operations. These applications require an integrated infrastructure for distributing audio, video, and control from sources such as videodiscs, media servers, broadcasts, and Internet streams to displays. A high-quality multimedia experience is essential for conveying messages and information effectively to employees, business associates, and customers. The CABA Intelligent & Integrated Buildings Council (IIBC) White Papers Subcommittee that I chair has issued a paper on multimedia distribution networks in buildings. The paper is entitled, High-Quality Multimedia Distribution in Commercial Buildings. This article is a summary of the paper, which is available on the CABA Web site. Evolution of building cabling
“Building infrastructure cabling” has traditionally meant power wiring and support for building automation services such as environmental control, lighting, and communications. These core-building functions are usually included in the domain of the building management organization. Cabling for telephone and computer networks have traditionally been the responsibility of the tenants. The term structured cabling refers to an organized installation of wires in a building for data network applications. These wires may be bundled into a common sheath for ease of installation. National and international standards specify the topology and performance requirements of such cabling systems. Before there were standards, the installation of wiring for services such as telephone, data networks, and cable TV was not well organized. Typically, wires were run from device to device in an ad hoc fashion for rapid installation and minimum wire usage. This topology might deliver unequal

signals to the devices, which would result in a degradation of data transmissions and video reception. The structured cabling standards require “star wiring.” Star wiring consists of many wires emanating from a single distribution point in the building to each floor in a hierarchy. The elements of this hierarchy are the campus, the building, the floor, a possible distribution point on a floor to support an open-office plan, and finally the outlet where computer and audio/video (A/V) equipment are connected. Figure 1, adapted from the international standard ISO/IEC 11801, Generic cabling for customer premises, shows the topology of structured cabling for commercial buildings. Star wiring, in general, uses more cabling material than bus or device-to-device wiring. However, signal quality is controlled better with star wiring. Also, less drilling through wood studs in the wall is required when installing star wiring. The international standard specifies signal quality for the entire communications channel, which includes the wires, connectors, and any patch cords. Video distribution
Video distribution cabling has usually been limited to pointto-point solutions such as coaxial cables and specialty cables for projectors. Extending coaxial cables throughout a commercial building for high-quality multimedia distribution is not a practical option because of costs and content-protection agreements. The media industry has selected the High-Definition Multimedia Interface (HDMI) as the primary suitable interface between video players of commercial content on media (such as Blu-ray discs) and video displays (monitors, televisions, and projectors). This interface was designed for the transmission of uncompressed data carrying high-definition video. HDMI includes data encryption and a control

channel to protect the distribution of content considered high value. HDMI has been implemented in specialized cables that are typically 10 feet in length (with a limit of 50 feet). A plenum-rated 50-foot HDMI cable costs about $200-300 compared to less than $20 for a comparable Category 6 (Cat 6) Ethernet cable. Furthermore: • A 50-foot HDMI cable weighs about four pounds. • An HDMI cable is almost a half-inch thick. • An HDMI cable has a limited bend radius. • The HDMI connector assembly is large compared to other connectors. • HDMI connectors are complex and expensive, as are field termination tools and kits. Thus, HDMI is not practical for a building infrastructure. To address this distance limitation and yet provide all the features supported by HDMI, a new technology was developed called HDBaseT™.

External network
HDBaseT technology
HDBaseT converts signals passed via an HDMI interface into a format suitable for transmission via the same type of local area network (LAN) cabling as used for Ethernet data communications. Transmission distances can span hundreds of feet while maintaining the quality of the source material. HDBaseT technology consists of electronics that convert A/V and control signals, including uncompressed high-definition (HD) and ultra-high-definition (UHD) video, into a format suitable for RJ-45 Plug transmission on standard local area networks via RJ 45 connectors as illustrated. HDBaseT electronics may be externally attached to or embedded inside A/V sources and displays. Since HDBaseT uses the same type of infrastructure as data LANs, once cable installers are trained for LAN installations, they will have the skills to install high-quality A/V

networks with HDBaseT technology. HDBaseT carries all the HDMI signals (audio, video, and control) plus Ethernet, USB, and up to 100 Watts of direct current (DC) power, called Power over HDBaseT (PoH). Power over HDBaseT A new technology for delivering power to office equipment over local area network cabling was introduced in 2001. This power delivery system is called Power over Ethernet (PoE). DC power is delivered using the same wires that carry data. Two standards have been issued for PoE to supply about 13 Watts and PoE+ to supply 25 Watts via office network cabling. HDBaseT extends PoE to 100 Watts with a feature called PoH using four pairs of local area network wires. If PoH equipment is connected to a PoE line, the maximum common power will be passed between them, i.e., according to whether PoE or PoE+ devices are installed. The higher power of PoH compared to PoE is applicable to video equipment in the office such as:
• Digital signage displays • Displays for local video sources and streaming (Internet) TV • TVs (displays with tuners) for high-definition broadcasts
CABA iHomes and Buildings Summer 2015
• Video switching units • HDBaseT extenders PoH at 100 Watts is enough power for operating most TVs up to 60 inches (diagonal measure). The U.S. EPA (Environmental Protection Agency) Energy Star program for TVs requires consumption for a 60-inch TV to be no more than 98.7 Watts, down to 21.9 Watts for a 20-inch TV. HDBaseT applications and venues Static message boards are giving way to dynamic presentations with graphics and video using high-definition displays. The phenomenal market growth of LCD (liquid crystal display) high-definition and ultra-high-definition displays has resulted in low-cost, high-quality large-format displays for commercial applications. These video displays offer the opportunity for visual information presentation and corporate messaging in public spaces, company lobbies, conference rooms, and even office areas. Our increasing expectations for higher quality multimedia pose challenges for developing technology that can adapt to higher resolutions and faster data-distribution rates with lower latency (delay). The technology for high-quality multi-media distribution requires high-resolution source material, high-resolution displays, and a distribution network that can stream high-data-rate audio and video.

KEN WACKS’ PERSPECTIVES
HDBaseT achieves these performance goals to support a variety of applications in a variety of commercial buildings, as listed in the following table. Multimedia Applications in Commercial Facilities
• Integrated circuits and modules • Matrix switches • HDMI • HDBaseT converters • Projectors with HDBaseT ports • Displays with HDBaseT ports
Multimedia Applications in Commercial Facilities Corporate information networks for building visitors and employees Hospitality, such as hotels and cruise ships In-flight entertainment systems Fitness centers Education applications Conference rooms Public displays with multiple screens Government agencies Power system operators Healthcare
These components and products fulfill the requirements outlined by the HDBaseT Certification Program (http://hdbaset.org/certification). This program verifies that products comply with the HDBaseT specifications to promote interoperability among vendors of current and future HDBaseT products. Figure 2 illustrates a multi-media conference room designed with such equipment. Thus, high-quality multimedia can be distributed on a network that parallels a building data network and uses the same types of cables, connectors, and topology. Multimedia distribution in commercial buildings is now feasible, cost-effective, and easily installed without special cables, connectors, or additional training.

OPINION
HVAC Growth to be Driven by Retrofit, Energy Efficiency Improvements By Omar Talpur
The United States Congress, with bipartisan support, has passed a bill titled the Energy Efficiency Improvement Act of 2015. The bill aims to promote energy efficiency in commercial buildings in three ways: • By developing a new voluntary energy program within the current Energy Star framework. • By adopting new regulations for smart grid-enabled water heaters. • Promote benchmarking and public disclosure of energy usage for buildings so tenants and building owners can better understand the current energy performance level of their space. While it is presently unclear in the current language of the bill if or how the public disclosure of energy usage for individual buildings will be accessible to the general public, the HVAC industry could greatly benefit from such legislation if that is indeed the case.
Currently in the United States, Energy Star certifications act as a way for building owners to show the general public that they are doing their part in limiting energy usage. However, these programs are voluntary and there are no penalties when standards are not reached. If information on energy usage of buildings was accessible to the public, building owners and businesses that were found to use an exorbitant amount of energy could be put under pressure by environmental advocacy groups and the general public to find ways to cut power consumption. This could be an important development in promoting energy efficiency as many political leaders at the state and federal levels are unwilling to pass prescriptive and punitive energy reform measures for the fear of being branded anti-business. The bad public relations which could arise from the disclosure of energy consumption could force buildings to upgrade old and inefficient HVAC equipment at a faster rate. For example, in the United States nonresidential retrofit market, IHS forecasted total units of air conditioners to

grow from 475,000 in 2014 to 513,000 in 2017, a compound annual growth rate (CAGR) of 2.6 percent. With public pressure being an additional driving force behind replacement of inefficient air conditioning units, the CAGR could reach closer to five percent. In addition to higher spending in HVAC equipment, buildings could also invest in more comprehensive HVAC controls systems and spend more on the service and maintenance of the new equipment and controls. This would lead to a further boost in retrofit and replacement HVAC business in cities with a high number of commercial buildings. While the total construction market in the United States has grown at a modest compound annual growth rate (CAGR) of 2.4 percent from 2012 to 2014, IHS found in its recent report titled the “World Market for HVAC Equipment” that 65.2 percent of total HVAC units sold into non-residential buildings were retrofit sales. Due to the large installed base of equipment in the United States following the 2009 economic collapse, IHS was not entirely surprised by the high retrofit rate of HVAC systems; nevertheless, it was interesting to see the broad variations that can occur among end-users within the same country.
For example, using building stock and construction statistics, IHS found that 79 percent of air handling units (AHUs) sold into the education market in the U.S. went to retrofit projects, which equates to roughly 12,000 schools replacing one AHU. In comparison, only 58 percent of AHUs sold in the industrial market went into similar retrofit projects, which equates to 10,000 industrial buildings making one AHU replacement. This shows that while industrial building has rebounded, in both new construction and spend, budgets for buildings in the education vertical have been more geared to maintaining existing structures. Understanding the differences in the retrofit and new build markets has been extremely important for manufacturers over the past five years as economic progress has been slower than expected. As the United States continues its recovery and budgets are refreshed, tracking the retrofit and new build markets will remain an important metric for growth opportunity, especially as energy efficiency recommendations continue to evolve.

the “human factors” is the global lack of qualified facility engineers and technicians, and the new skill sets needed to manage and operate a building and its systems. Yes, some of the analytic software applications can help and support facility staff. Also we can expect some companies to take analytics to a another level and develop software that will not only detect faults but automatically remedy some but not all of the issues, such as changing set points or changing values or flow or pressure, etc. by extending analytic rules for the building systems. At some point however, a trained, competent human being will be required to diagnose and remedy problems or issues with equipment, tools and knowhow. A study in 2011 by IFMA found the average age of a facility manager is 49 years old. Yet the percentage of people in their 20s and 30s in building operations is relatively small. We face a dearth of qualified personnel worldwide. The industry needs and must come together to address how to attract younger people into the industry and how to train

people. Some of the potential avenues maybe include the educational system, trade associations, vocational schools, unions and internships. Some in the industry have tried to define the “Electrician of the Future” or the “Facility Engineer of the Future”. The expectation is that a person would not only be knowledgeable or an expert in mechanical, electrical, security, etc. but also versed in the basics of information technology. It’s fair to say that the next generation of facility personnel will have different approaches to communications and collaboration, using tools as social media, gaming, video and a number of apps, and potentially being attracted by the energy and environmental aspects of buildings.
