Intelligent Buildings is a well-known and leading-edge consultancy company in the smart building business. Veteran Tom Shircliff elegantly brings to light that the technology, all of the smart technology pieces needed for New Buildings, for Building Retrofits, for Building Analytics, and for Building System Cyber Security are here, but the challenge is how to scale this available technology into starting points — where building owners can get under-whelmed and start faster, with less risks, and all the while, make enlightened decisions quicker through Intelligent Building’s organizational alignment approach and the creation of a common language that all the stakeholders can understand. To ease and accelerate that sometimes arduous process, Intelligent Buildings has created their Advisory Starter Kits, which allow building owners to implement immediately, specific best practices and establish vital vendor standards, that will ultimately ensure a complete and successful future project solution.

Siemens releases two new products for use on surfaces where condensation must be avoided. Both the QXA2601 and QXA2602 are designed to prevent condensation from forming in chilled beam and chilled ceiling applications. Both devices operate identically via an SPDT relay that changes state when humidity level near the surface of the chilled water piping approaches 92%. The unit will automatically reset when the humidity level drops to approximately 87%.
The key difference is that the QXA2601 is a completely self-contained unit that attaches directly to the chilled water piping, while the QXA2602 features a remote sensing element that is easier to locate in small spaces. The QXA2602 includes 5’ of cable for connecting the remote element to the relay housing.
Product Description: The QXA2601 and QXA2602 Condensation Monitors are used to avoid damage due to condensation on chilled ceilings and in HVAC installations. They are equipped with an SPDT dry contact capable of switching 1 amp @ 24 Vac or 0.5 amp @ 24 Vdc. A two-color LED provides visual status indication. The QXA2601 includes hardware for installation on pipes with outside diameters from 0.39 to 3.94 inches (10 to 100 mm). The QXA2602 includes hardware for surface mounting on walls or ceilings.
Product Use: For monitoring condensation in buildings that utilize chilled beam or chilled ceilings or in HVAC installations. In general, the condensation monitor is for use on surfaces where condensation must be avoided and used in following applications:
• to prevent condensation on chilled ceilings.
• to prevent condensation at critical spots of HVAC installations or buildings (in air ducts, near fans, and so on).
• as a condensation switch.
Equipment Combinations: The QXA2601 and QXA2602 can be used in any 24V AC/DC control circuit and can be wired NO or NC to provide indication of pending condensation.
Mode of Operation: With its sensing element, the condensation monitor acquires the relative humidity close to the dew point (= 100% rh). The resistance of the sensing element rises sharply in the range of 90 to 100% rh. Before the dew point is reached, the electronics energize the relay. When, as in the case of chilled ceiling applications, the relay contact switches over and may be used to trigger a condensation avoidance sequence such as:
1. Cooling will be shut down via the valve or by a controller until the condensation signal is no longer present.
2. The water flow temperature will immediately be raised by an adjustable value (typically ≈ 2˚F) and slowly reduced again after the signal has disappeared. This application requires a specific function in the controller.
Simple to set up, with no software needed, this controller is powerful and functions equally as well as a stand-alone solution or the VAV controller of choice on a BACnet full-blown control system.
The SimplyVAV series of controllers are an easy and unique approach to operating a wide variety of VAV terminal units. The integrated actuators, internal airflow sensors, and wide variety of application programs make these BACnet Application Specific controllers ideal for either new or retrofit installations.
The controllers feature simple, menu driven setup choices when used with a SimplyVAV digital sensor. No special programming skills or software tools are required to choose applications, enter setpoints, set network addressing,and balance airflow. All options can be set by using only an STE-8001 sensor, which can be installed as the permanent room sensor or temporarily connected as a technician’s service tool.
All models are BACnet Application Specific Controllers that are ready to connect to a BACnet MS/TP network. Device instance, MAC address, and baud rate are set from an STE-8001 without special software.
The KMC Simply VAV Controller is sure to be in the hunt for an Award at the 2014 ControlTrends Awards.

All the Big IT companies are running campaigns touting their role in the coming Internet of Things (IoT) computing era. A common vision is that software, particularly mobile apps, will reign supreme over embedded systems-on-a-chip, sensors, wireless communications and other components making more of the physical world digitally addressable. But, it is building automation and control firms – sometimes called OT, or operations technology companies – that have had to slog through decades of navigating relationships with big equipment makers to tap silo-ed data and do the necessary integration. All this work deserves its rightful recognition. But, as long as all the IoT marketing leads to substantive progress in building energy efficiency, does it really matter who takes credit?
I’ve been thinking about this in light of the US General Services Administration’s (GSA’s) Smart Buildings Analytics project. This project might be as close to a ‘No Spin Zone’ for building operational analytics at portfolio-wide scale as exists in the United States today. In May 2012, IBM was awarded the GSA fulfillment contract and it brought in partner ESI — one of these OT pioneers. The scope of the first phase of the project was to bring 55 GSA buildings around the country under better control through data analytics. At the 2014 Building Energy Summit in April, IBM and ESI presented a status report on the project, and this presentation has just been posted on youtube with accompanying slides available from the Summit’s organizer, CoR Advisors. So we can all see for ourselves how the project is balancing its Big IT and OT components. I’ll say that if you do an IT vs. OT analysis of this content – glancing slide-by-slide or frame-by-frame in the video – it’s more OT than IT. But, again – not the point.
Notably, in late 2011, IBM did a lot of marketing about its own Intelligent Building Management Software. Despite this marketing blitz, for the GSA project, ESI took the operational analytics lead deploying the SkySpark’s analytics engine from SkyFoundry. The architecture called for the information about equipment maintenance needs and energy usage trend data to be streamed to the IBM Workplace Management suite for further decision making. Familiar to CTO’s and CFO’s, the Integrated Workplace Management software category is a flavor of Enterprise Resource Planning (ERP) software with custom-tailoring for facilities/real estate managers that want support in making financial decisions that relate to building and equipment assets, utility costs and carbon management reporting. IBM acquired TRIRIGA in 2011 to improve its offering and competitive position in this category.
The presentation gives a snapshot of the GSA project about 18 months in. IBM and ESI have proved the case for their Big Data approach to building energy efficiency, finding and correcting typical energy and money wasters like stuck dampers on air handlers and cases of simultaneous heating and cooling. More than that, the GSA project has revealed the real delimiting factor in continuing the data-driven approach. It’s not about IT or about OT – or about technology at all. Rather it’s about people and skills. Current facilities and building operations personal need retraining, or new digital natives need to be attracted into the profession. If the glossy and pervasive IoT awareness campaign can do this, everybody wins. Cheerios didn’t invent oats, but a great marketing campaign did get more kids to eat them. John Petze of SkyFoundry offers some great insight into the necessary mindset in his article “Considering Analytics? Start By Assessing Your Data Maturity Level.” Like other OT experts, he offers the message: Be inspired. There’s a great future in Buildings IoT. But be realistic too.
