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.”
