o New Committee members

Research – Werman

o TRP 1673- Revision to the HVAC Design Guide for Tall buildings- Bid evaluation- This was an executive sessionIt was moved and seconded that RP 1673 was be awarded to Building and Systems Analytics for $90,000. Principal Investigator; Peter Simmonds. The motion passed.

o RTAR written by Len Damiano co-sponsorship of research on building pressurization control - We approved Co Sponsorship in Las Vegas.

o RP-1478 under TC - 4.3 in progress but regarding pressure testing in tall commercial buildings including wind effects. Using blower door test. Funding was less than expected from Oakridge National Labs. Wanted 24 buildings. Tested 7 buildings 3 to go on list. They are hoping for a building of 10-12 story height.

Mark needs some help with additional material for the website.

Program – Mark Fly/John Carter

o New York – Simmonds – The Tall Building workshop consisting of six programs was very well received. A list of the topics and the evaluation sheets are included in Appendix A to these minutes.

o Seattle

Handbook – Wessel o We need to vote to approve at this meeting or in Seattle at the latest.o Next version should expand on stack effect in tall buildings. o Some additional comments have ben received and an attempt will be made to

get the draft chapter out to the committee before Seattle to be ready for a vost at the Summer meeting.

Old Business - None

New Business

o TC-5.6 funded a research project to link the program CONTAM to others to provide a better means of dealing with fire and smoke in tall buildings. The project is completed and ASHRAE has the result. TC-5.6 asked us if we are interested in trying to find someone who would take the result and making user friendly software.

o What do we need to do to attract new members especially outside US? o Invite some YEA members. o Write letter to tall buildings designerso CEC special conference on tall buildingso Pankaj Dharkar from India wants to make connections with-in his country.

o In China central mechanical floor (floor by floor) in most high rise. 5 per week being built?

o Liaison with CBTUHo Liaison with Chicago Committee on High Rise Buildings CCHRBo Scope: should we change our scope to include mega tall and super tall

buildings? Adjournment –

Workshop 5: Is ASHRAE Tall Enough for Tall Buildings?Track: Tall BuildingsSponsor: 09.12 Tall BuildingsChair: Peter Simmonds, Ph.D., Stantec, Sherman Oaks, CA

This presentation evokes discussion on ASHRAE's role in the design and development of tall, mega tall and super tall buildings. The present ASHRAE definition of a Tall Building is a building that is taller than 300ft (100m). The scope of ASHRAE’s subcommittee for Tall Buildings is being revise to include Mega Tall, 300m and Super Tall 600m buildings. With the increase of a buildings height come engineering challenges which must be resolved. Some of the world’s leading expert and designers of Tall Buildings around the world will discuss present day trends with the audience.

Seminar 30: Current Trends in Tall Building DesignsTrack: Tall BuildingsSponsor: 09.12 Tall BuildingsChair: Ray Sinclair, Ph.D., Member, RWDI, Guelph, ON, Canada

There is a proliferation of Super Tall and Mega Tall Buildings being built around the world. These buildings exceed the height of the Empire State Building at 380 m. These tall buildings can be very slender on relatively small urban site and have unique forms and mixed-use function. An architect, a structural engineer and a mechanical engineer present on current trends in design that must provide integrated solutions to complex issues that are of interest to ASHRAE members.

Seminar 39: Specific Engineering Solutions for Tall BuildingsTrack: Tall Buildings

Sponsor: 09.12 Tall BuildingsChair: Luke Leung, P.E., Member, Skidmore, Owings and Merrill LLP, Chicago, IL

One World Trade Center is the primary building of the new World Trade Center complex in New York City's Lower Manhattan, this 104-story supertall skyscraper stands on the northwest corner of the 16-acre (6.5 ha) World Trade Center site, On May 10, 2013, the final component of the skyscraper's spire was installed, making One World Trade Center the tallest building in the Western Hemisphere and the third-tallest building in the world by pinnacle height. Its spire reaches a symbolic height of 1,776 feet (541 m) in reference to the year of the United States Declaration of Independence. It has been the tallest building in New York City since April 30, 2012, when it surpassed the height of the Empire State Building. This seminar will focus on the comprehensive technical elements of the building, from the high performance curtain wall, energy consumption, elevators, fire protection to the HVAC system of the building.  Focus will be on the special systems, energy and human performances of this tallest building in US..

Seminar 40: ASHRAE and Tall BuildingsTrack: Tall BuildingsSponsor: 09.12 Tall BuildingsChair: Dennis Wessel, P.E., Karpinski Engineering, Cleveland, OH

This session presents advancements in ASHRAE produced design guides and documents for tall buildings, such as the proposed changes to the ASHRAE HVAC Tall Building Design Guide and trends in Asian tall buildings. The next generation of super tall buildings promise to be much taller, there are multiple “Megatall” towers under construction that will exceed 600 M in height.  To understand the energy and environment of these buildings are critical for their successes.

BuildingsTrack: Tall BuildingsSponsor: 09.12 Tall Buildings, 05.06 Control of Fire and SmokeChair: William A. Webb, P.E., Fellow ASHRAE, WEBB FIRE Protection Consulting, LLC, Brooksville, FL

The seminar discusses the challenges of providing elevator pressurization in tall buildings. ASHRAE TC 9.12 defines a Tall Building as at least 300 feet tall. The background and outline of code requirements, for the systems are presented by one speaker. Another speaker describes design features including calculation means for pressurization airflow and pressure differential. This speaker also describes the challenges in achieving these values while allowing the elevator to operate. The final speaker presents a case study and lessons learned.

Seminar 46: Natural Ventilation for Tall BuildingsTrack: Tall BuildingsSponsor: 09.12 Tall BuildingsChair: Andrew Reilman, P.E., Member, Syska Hennessy Group, Culver City, CA

This seminar presents the practicalities of designing and applying natural ventilation for tall building and will describe how weather modeling can be used to generate climate data and then in turn how it is used for building energy analysis. The weather tool will be described, and then several case studies presented that demonstrate the value of this approach. The case studies will include different climates and different building heights and will include the application of natural ventilation is controversial for most buildings. Results of studies made for adaptive comfort conditions in mega and super tall buildings will be presented.
