• Where Is the BAS Industry Going?  Further, without new manufacturers entering the market (which bring new, fresh ideas to BAS products) what will lead the industry to product improvements and innovations?
• Everything gets old – dealing with obsolescence  One of the goals of using an open protocol based system is to be able to avoid obsolescence.
• Variable Frequency Drives and Building Automation Systems  Part 1 Proper Selection
• Proactive BAS Alarming for High Performance Buildings  To start implementing a proactive alarm management process, it is necessary to prioritize the alarms.
• How Far We’ve Come  you can see readily observe the “state of the art” from the 1970’s and 1980’s in many existing buildings
  
• Integration Myths, Lies and Misconceptions  More and more projects are involving the integration of more systems and/or equipment, many whose function is not for HVAC. - Paul Ehrlich, Ira Goldschmidt & Angela Lewis Building Intelligence Group
• BAS Usability  Creating high quality graphics is only half of the picture to support system usability.
• Can Specifications Lead the Advancement of Systems Integration?  Perhaps, but keep in mind that specifications in and of themselves do not dictate who does what.
  
• Set it and Forget It?  We suspect that this is exactly the approach that most designers, owners and contractors would really like to be able to take with their BAS installations.
• Alarms Lead to Reactive Operations  An alarm event indicates that a problem has already occurred.
  
• Making Commercial Controls Work  Nearly everything about a controls system—the points, architecture, integration, etc.—comes from the requirements defined in the sequence of operation.  
• Networked Building Automation System (BAS)  It is amazing how little we know about what really goes on in most buildings.
  
• Closing the Feedback Loop  What type of feedback is needed by each party? Answering this question is a bit more complex. Angela Lewis, Building Intelligence Group
• Why is it that control systems don’t work?  Focus on thorough control design and installation, coupled with good training and tools for continuous commissioning and monitoring. These are the keys to the delivery of high performance building operation platforms.
• When Does Building Automation Become Industrial Automation?  However tempting or logical it might seem to use industrial automation in complex building projects, it usually leads to problems (generally due to the technical and business practices “gaps”) that are greater than the benefits.
• BAS as a Tool for Existing Buildings Operations  Operations teams are tasked with running buildings that have minimal documentation and may never have been properly commissioned. New tools, processes, and training can help overcome these issues.
• Intelligent Buildings in the Age of Pneumatic Control?  How intelligent can a building be if most of the temperature control is provided by antiquated controls? 
• Integrated Lighting Control  Providing an efficient building requires good lighting control that includes coordinated scheduling, occupancy sensing, and daylight harvesting.
• Why Do Open Protocol Myths Still Abound?   We see plenty of opportunities for the industry to educate itself sufficiently to overcome these myths.
• Fundamental Changes  In June, Engineered Systems and Building Intelligence Group will be conducting the first Sustainable Solutions Conference. 
• Is Hospitality at the “Fringe” of the Intelligent Building Industry?  Hospitality-centric products appear to have been immune to the market pressure of open protocols, so we have solutions that do not enjoy the benefits of this advance nor can they readily integrate to the commercial controls.
• BAS System Tune Ups  Improving efficiency can be fairly complicated and expensive, but many changes can be made simply by tuning up the systems that are already in place.
• Integrating BAS’s To Everything All The Time?  Equipment or systems integrated to a BAS and how they are integrated is a project-by-project decision based on the needs of the client and the design.
• Smart Buildings Meet the Smart Grid  Keep the Smart Grid in mind as you start to work on your next project and think about how you can make the building a smart part of the Smart Grid. 
• The Coming Evolution of BAS Design  A good BAS design starts with a well thought-out sequence of operation and point list. 
• Advanced Controls Optimization for High Performance Buildings – Part II Water Side Last month’s column focused on the control of the air side with the use of strategies including demand controlled ventilation and static pressure reset. This month we would like to explore the control of the water side.

• Commissioning An Intelligent Building  Interoperability testing is an important key to the success of multi-manufacturer BAS’s and will become even more important to the success of Intelligent Buildings.
• BAS and Advanced, Integrated Lighting Control  New technologies including the use of wireless communications, networking and open standards are making the deployment of advanced lighting control practical in both new and existing building projects.
• Building Automation Wishes for a New Year  As with technology in general each advance seems to reveal the need for more advances to achieve that elusive state of perfection.
• BAS Use of Ethernet / IP Infrastructure II  Use of Virtual Local Area Networks
• BAS Use of Ethernet/IP Infrastructure Simply put, should a BAS use its own dedicated Ethernet/IP system, or should it use that provided for the building’s business-enterprise communications and managed by the IT department?
• Data Center Building Automation  In many ways data centers come closest to blurring the line between commercial and industrial controls in our industry.
• Selecting the Building Automation or Systems Integration Contractor  The process that we use involves a formal “Request for Proposals” (RFP), allowing us to gather information and evaluate it in an impartial manner.
• Differentiating an Intelligent Building These three levels of an Intelligent Building system can result in a significant improvement of system operations, operational efficiency, and high level tools for facility assessment and optimization.
• An Intelligently Green Building  The imagination of the building design team (along with the willingness to research and specify the technology and products involved in this integration) is the only limit to creating intelligently green buildings. 
• Controlling Demand Response  A building that has been designed for demand response can readily drop electric loads with little impact on the occupants.
• Campus Automation Presents Unique Challenges  Multiple interfaces makes campus-wide optimization, data mining, and energy and operational analysis difficult.  
• More on the Challenge of Writing the Controls Specs….   Open/standard communications protocols is probably the most important example of where a specification should contain explicit, prescriptive requirements.
• Writing the Controls Specs…. One of life’s great challenges  In reality the design of the controls system really starts with the selections made for the mechanical and electrical systems and a good understanding of how the building will be operated.
• Green Intelligent Buildings – a Brief History  The original concept of Energy Management, which later became Building Automation, started in earnest as a result of the OPEC oil embargo in 1973. 
• How Automated Are Our Green Buildings?  The new draft “LEED for Healthcare” document is not poised to add any new warmth to our hearts.  A close look at this document (or any LEED rating system for that matter) reveals very little direct reference to the use of building automation.  In fact the term “building automation” appears to be used only once in the entire document!  
• New Year, New Beginnings  “We don’t plan to fail, but often fail to plan”.  
• Delivering Sustainability   Sustainability is a complex issue and involves many decisions ranging from the use of recycled materials to safe cleaning chemicals.
• Intelligent Buildings Roadmap  “The industry needs to get together to integrate or at least educate all of the people that are involved. The owner cannot integrate the industry, the architect cannot integrate the industry, the industry must integrate itself and take the lead…” 
• Intelligent Buildings – Today!  The concept of an Intelligent, Smart or “Next Generation” building has been around for years.
• Help Wanted: Building Systems Architect
• Why your next project should be an Intelligent Building  In addition to being a better building to live, learn, work and play in it can also be a very satisfactory investment for any owner.
