National Institute of Standards and Technology

Since 1987 the American Society of Heating and Refrigeration Engineers has lead development of the de facto standard for campus building automation systems 135 BACnet® – A Data Communication Protocol for Building Automation and Control Networks. This title supports the #WiseCampus transformation in two important ways:

  • It defines data communication services and protocols for computer equipment used for monitoring and control of HVAC&R and other building systems
  • It defines an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

BACNet Committee: ASHRAE SSPC 135

Since the late 1970’s these systems have grown from single building control networks for environment air into multi-building campus-wide systems that conform to the ISO model of layered communication architecture.   Every large research university has long since installed facility management unit that monitors and controls points such as outdoor air intake, wet-bulb temperature, occupancy load, elevator action, time of day, outdoor lighting etc.    The University of Michigan, for example, monitors and controls nearly 1 million control points on its 6 square mile Ann Arbor campus.

The ASHRAE 135 technical committee has released a consultation on addendum cd regarding cipher suite application security profiles.  Several redlines are now open for public consultation and may be found here:

ASHRAE Public Review Drafts Standards

Consultation on several titles is open until March 20th.

This title, and several others in the ASHRAE catalog, are on the standing agenda of our Energy 200 and Energy 400 colloquium.  See our CALENDAR for the next online meeting; open to everyone.

“You shall above all things be glad and young…”

Weddings

…For if you’re young, whatever life you wear

it will become you; and if you are glad

whatever’s living will yourself become.

Girlboys may nothing more than boygirls need:

i can entirely her only love

whose any mystery makes every man’s

flesh put space on; and his mind take off time

that you should ever think, may god forbid

and (in his mercy) your true lover spare:

for that way knowledge lies, the foetal grave

called progress, and negation’s dead undoom,

I’d rather learn from one bird how to sing

than teach ten thousand starts how not to dance

e.e. cummings

Sonnet 116

 

Let me not to the marriage of true minds

Admit impediments.  Love is not love

Which alters when it alteration finds.

Or bends with the remover to remove.

O no! It is an ever fixed mark

That looks on tempests and is never shaken;

It is the star to every wandering bark.

Whose worth’s unknown, although his height be taken.

Love’s not Time’s fool, though rosy lips and cheeks

Within his bending sickle’s compass come;

Love alters with his brief hours and weeks,

But bears it out even to the edge of doom.

If this be error and upon me proved,

I never writ, nor no man ever loved.

 

— William Shakespeare
