TALL BUILDINGS

June 29, 2004

Nashville, TN

Minutes of Meeting

Chairman Simmonds called the meeting to order at 3:40 pm

The minutes of the Anaheim meeting were approved 6-0-0 (2 absent)

Chairman’s remarks – Peter Simmonds

  1. We will develop information to be included in the next Applications Handbook (2007). Lynn Werman will be our sub committee chairman for this project. Our source will mainly be the recently published “Design Guide”.
  2. Harvey Brickman reported that the “Homeland Security” ad hoc committee has been reappointed for another year. Harvey is our representative on the committee. They report that the teleconference was well received.

Programs – Dennis Wessel

  1. “Case Histories of HVAC Systems of Four of the World’s Tallest Buildings” That Are Completed and Occupied”. This will be scheduled for Orlando as a symposium. Ray Clark has submitted a brief synopsis for Jin Mao Tower. Harvey will contact Flack & Kurtz, Cosentini, and Jaros, Baum, & Boles to try to get 2 or 3 papers. Tom Kroeschell will be chairman. Dennis will submit application.
  2. We will propose something unique for Chicago. (With consideration to the high rise environment in Chicago.) We will request back-to-back symposium sessions on tall buildings. One would feature “Trump Tower” – a multi use tall building that should be under construction at that time. Sections to include HVAC, Life Safety, Fire Protection, Architecture, and Electrical. The other will feature “Seven World Trade Center” and “Freedom Tower” (Both JB&B – SOM buildings.) Harvey and Tom Kroeschell to Chair. Please note, that after the meeting, Peter discussed this with the program committee and they suggested that this be a public session. Dennis will submit application.
  3. We will propose a seminar for Denver on “Atria Ventilation”. Subject to be covered is CFD systems to reduce required exhaust air. This would be part talk with examples and allow time for open discussion regarding code interpretation. Peter to chair. Possible co-sponsor would be TC 5.6. Dennis will submit application.

Handbook – Lynn Werman

  1. The material will be included in the “Applications Handbook” (2007). An abstract and outline are included with the minutes. Sub committee assignments are shown on the outline.
  2. Authors will use the recently published “Design Guide” as a basis for write-ups.
  3. It will be mainly on commercial buildings; but it will include a statement regarding similarities between commercial buildings and residential buildings in the document.
  4. June 2006 is the deadline for submission.
  5. The sub committee will meet directly following the main committee meeting at Orlando.

Research – Mark Fly

  1. Regarding TRP-1130. “Case Studies of Mechanical Systems in Super Tall Buildings”. Mark Fly will rework the work statement and write a RTAR.
  2. Regarding TRP-11231. “Air Infiltration in High Rise Buildings”. Tom Kroeschell reported that Jim Braun will give us an assist by rewriting this work statement and he will ask Jim to write the RTAR also.

Mark Fly will resubmit both of the above projects.

Adjournment: The meeting was adjourned at 5:00 pm

ABSTRACT ON TALL BUILDINGS FOR ASHRAE HANDBOOK

Tall buildings have existed for more that 100 years. Tall buildings became possible through the invention of the elevator and gained popularity as populated cities of concentrated economic activities developed infrastructures that would support business enterprise on limited building sites. The design of any tall building is the result of a unique collaborative effort of owners, architects, structural engineers, mechanical engineers, and electrical engineers with specialized talents. Beyond the advent of air conditioning, over the past several decades a series of significant changes have modified the basis of design of the air conditioning systems for tall buildings. These changes have been addressed in ASHRAE’s recently published “An HVAC Design Guide for Tall Buildings”. As stated in this design guide, “Nowhere is it of greater importance than to the HVAC design professionals who are responsible for the documents that define the basis of the installations that are provided for any large commercial office building”.
