BACnet Unplugged: Updates Made to Building Controls Standard   (ATLANTA)
Advances related to the BACnet standard, including recommending public review for an addendum that would tunnel BACnet over ZigBee wireless networks, were made during ASHRAE’s recent Winter Meeting.

Proposed Addendum q would lead to a significant reduction in the cost of installation at the sensor and controller level by reducing the amount of wired networking required in a building automation system, according to Jerry Martocci, convener of the BACnet committee's Wireless Networking working group.

"Marrying these two technologies seemed obvious," said Martocci. "BACnet already had the object and services model designed specifically for building automation but no wireless network, and ZigBee had the wireless capabilities but no object model for building automation. We just had to put the two together to benefit from the synergies."

The addendum recommendation began about two years ago with meetings between BACnet and ZigBee experts. "During this time we learned about ZigBee’s data communications, and they learned about BACnet’s networking and objects and services model," said BACnet chairman Bill Swan. "Together, we looked at a number of approaches and discussed the pros and cons of each."

For various technical reasons, battery-operated devices, including sensors, will probably be ZigBee only, but powered controllers would have BACnet/ZigBee capability. Martocci notes that the "mesh" networking among ZigBee nodes leads to self-healing networks, so that even if a link between two nodes is obstructed, the "mesh" network can route around the obstructed link, leading to reliable networks.

In other developments, the BACnet committee worked toward approval of nine additional addenda during the meeting. "Only a few of these are going out for first public review," said Swan, "but it is our expectation that these are all likely to pass without significant comments."

One such addendum is Addendum j, support for physical access control. This was drafted by the Life Safety and Security working group, comprised of BACnet and experts from the physical security industries. Public reviews of Addendum j have been announced in journals and other media serving the security industry, with long review periods to help ensure it gets the most complete review possible.

Another addendum being prepared for public review is Addendum i, support for lighting applications. This addendum was drafted by the Lighting Applications working group, comprised of representatives from lighting controls manufacturers and BACnet experts.

The BACnet committee continues to work on a broad range of other items, such as integrating buildings and the energy utilities, developing standard profiles for various building automation devices, CCTV control, and elevator monitoring.

 

International Code Council Takes Action on ASHRAE Proposals  (ATLANTA)

International building codes may soon incorporate requirements from a new load calculation standard from ASHRAE and ACCA under several recent proposals now under consideration.

ASHRAE made 15 proposals to the International Code Council (ICC), which develops model codes that may be adopted by code jurisdictions in the United States or internationally. After a public comment period of the committee recommendations of proposals, final hearings for the code change proposals will take place in September 2008. If the proposals are accepted, they would be included in the 2009 code. 

Under a proposal to both the International Mechanical Code (IMC) and the International Energy Conservation Code (IECC), references to load calculation guidance in the ASHRAE Handbook, Fundamentals, would be replaced with requirements from a new ASHRAE standard developed with the Air Conditioning Contractors of America (ACCA), ANSI/ASHRAE/ACCA Standard 183-2007, Peak Cooling and Heating Load Calculations in Buildings Except Low-Rise Residential Buildings. The standard establishes minimum requirements for building loads that are inclusive of as many procedural methods as possible while identifying core elements that impact heat loss and gains.

“The guidance in the ASHRAE Handbook was never intended to serve as a reference document to codes,” said Steve Ferguson, ASHRAE assistant manager of standards – codes. “Standard 183 provides an appropriate consensus reference standard that is appropriate for adoption in the ICC codes.”
Also approved were proposed changes regarding lighting stringency based on requirements in ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings. These changes include:

  • Adding exceptions for typical lighting requirements, which would eliminate conflicts with the code and accepted lighting design practice that are commonly applied.
  • Allowing calculation of track lighting wattage, which provides an important practical application. Without this provision, users may be forced to claim more wattage than it is possible to put into the application.
  • Modifying lighting power allowances, which would eliminate issues in the allowance section through appropriate and practical application of these additional allowances. While simplifying the application, it also will increase energy savings, according to Ferguson.

Also related to 90.1 was a proposal to modify chiller requirements. The proposal calls for, effective Jan. 1, 2010, an additional path of compliance for water-cooled chillers and consolidation of, and new requirements, for some of the existing categories.

Also approved was a proposal from ASHRAE to add new refrigerant classifications to the IMC from ANSI/ASHRAE Standard 34-2007, Designation and Safety Classification of Refrigerants.
 

Applicant to work in government advisory role ASHRAE and USGBC Cosponsor Washington Fellowship  (ATLANTA)

 

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the U.S. Green Building Council (USGBC) have joined forces to sponsor a one-year fellowship in Washington, D.C., that will allow the participant to work in the federal government in a technical advisory role. Members of ASHRAE or USGBC may apply.

Possible placement areas include Congress, a federal agency such as the Department of Energy, Environmental Protection Agency or the General Services Administration, or the White House Office of Science and Technology Policy.

“Federal government fellowships provide a valuable public service to the nation while at the same time providing engineers and scientists with a unique opportunity to participate directly in the policy-making process,” says Doug Read, ASHRAE program director of government affairs. “This is an exciting, rewarding, and educational period in their professional careers. This enriching experience enables fellows to bring back to their employers an insider's perspective on government decision making that can contribute significantly to the mission and vision of the organization.” 

“The fellowship is designed to educate participants on the inner workings of federal policy-making,” said Jason Hartke, director of public policy, U.S. Green Building Council. “The fellowship is an opportunity to provide scientific guidance and analysis to decision-makers, and to increase the visibility and involvement of scientists and engineers in the public policy arena.”

The fellowship runs from September through August 2009, and an orientation is conducted through the American Association for the Advancement of Science. A $50,000 stipend will be provided to the selected fellow.

Candidates should possess a doctoral or other terminal degree in engineering or another building-related scientific discipline. Final placement of the selected fellow depends on the needs of the government offices and agencies at the time as well as on the skills and experience of the applicant.

The deadline for applications is May 1, 2008. ASHRAE or USGBC members interested in applying for the fellowship should contact Doug Read, ASHRAE program director of government affairs, at 202-833-1830 or dread@ashrae.org.

Lessons from ASHRAE Roundtable on High-Performing Buildings Shared in Video  (ATLANTA)

Early involvement by all members of the building team is crucial to the success of high-performing buildings, according to panelists in a new video from ASHRAE.  “You can’t operate efficiently if the building hasn’t been designed with that in mind,” said Don Winston, P.E., director of technical services, The Durst Organization, Inc. “The operators will always win in the end. If you don’t design it in a way that it can be operated in accordance with its performance goals, it won’t be….it really goes back to the design process and a level of cooperation. Everyone has to be in on it, including the operations team, from day zero.”

Lessons learned in sustainable design can now been seen via a free online video at www.ashrae.org/roundtable. The video is a recording of a special roundtable, High-Performance Buildings: Lessons from the Leaders, originally presented at ASHRAE’s 2008 Winter Meeting.  The panelists discuss owner motivations, technical challenges, design choices and trade-offs, costs for these projects, and share perspectives about whether the expectations set early in the design process have been met once the buildings are occupied.  The panelists include representatives of New York’s best-known owner/developer firms. along with the engineering designers who bring their projects to reality. Their projects include some of the most sustainable buildings in New York City, such as 4 Times Square, the Chrysler Center, One Bryant Park and the New York Times Headquarters.
“What does high performance mean?,” questions panelist Tom Scarola, director of engineering, Tishman Speyer. “Up until even a few years ago, buildings were designed very prescriptively based on meeting codes, not challenging whether they could perform better. What we do today is called high performance but it is just good and efficient design. It is reasonable to believe that the issue is no longer if it is a high-performance building, the question is how high. Building a high-performance building means never having to say you’re sorry.”

The panelists agree that it is essential that planning for the design, operation and maintenance of high performing buildings start early and involve all members of the building team. They also agree that designers and engineers should strive to incorporate new technologies and design methods.
“Put behind you what’ve done for the last 20 jobs,” suggests panelist Scott Frank, P.E., partner, Jaros Baum & Bolles. “Get in the habit of saying ‘how can we do this differently,’ ask ‘why not’ at every turn, worship the god of common sense, and be sure every decision and recommendation you make is backed up by rigorous engineering.”  Dan Nall P.E., senior vice president/director-advanced technologies, Flack + Kurtz addresses sustainability outside the U.S. market.  “Perhaps the most informative experience I have had is working on projects in the Middle East, where the entire support infrastructure is being built at the same time as the buildings. This provides an opportunity to investigate the relations of multiple buildings to their support infrastructure and the opportunities that exist to create a complex cascading utilization of resources. The answer doesn’t lie in making individual green buildings – it lies in making green cities.”
