Using Life-Cycle Assessment in Designing High-Performance Buildings

Wednesday - October 29th, 4:00pm - 4:30pm
Session ID: LSW6
Session Speaker: Rita Seraderian, PE, FPCI, LEED AP (PCINE)

High performance structures go beyond being built sustainably to include a full set of environmental impacts during design to improve resiliency and long-term performance. Case studies will describe high-performance precast buildings and key elements to their performance including life-cycle assessment and environmental product declarations.

FREE WEBINARS

Designing Industrial Structures with Precast Prestressed Concrete

Presenters: Greg Winkler and Chris Lechner
Oct. 14 and 16

Risk

Description: The concept of ‘high-performance’ encompasses sustainability, and goes beyond a single criteria approach by requiring optimization of all relevant attributes for a project on a life cycle basis.

This webinar will education participants regarding how precast concrete systems allow an industrial structure to meet the demands of heavy use and dynamic production advancement. Additionally, the program explores the use of precast concrete components for specific industrial, retail, and manufacturing applications that take advantage of precast concrete’s fire-resistance and long roof span capabilities. Participants also discover benefits to the designer and owner in terms of increased durability, flexibility of design, high quality of manufactured products, versatility, high-performance, durable materials and speed of construction because precast components can be erected quickly once they arrive at the site.

Learning Objectives:

  • Identify and discuss the different industrial applications for precast, prestressed concrete systems
  • Discuss high performance attributes of precast concrete systems in industrial structures
  • Explain the benefits of using precast, prestressed concrete in industrial structures
  • Make an informed material choice for your next industrial building design

University of Massachusetts-Lowell South Campus Parking Structure, Lowell, MA

University of Massachusetts-Lowell South Campus Parking Structure

Administrators at the University of Massachusetts-Lowell needed to expand on-campus parking supply for faculty, staff and students. The site-selection process identified a location, footprint, and orientation that required the structure to be built into the side of a hill at the end of an existing surface lot. A structural-system selection study was performed to consider construction schedule, campus disruption, cost, availability, and long-term durability. The study identified precast concrete construction as the preferred system for the seven-level, 764-car facility.

“In the Northeast, it’s pretty common to use this system for parking structures,� says Christopher Brennan, director of operations and the project manager for Walker Parking Consultants in Boston. “It’s the most prevalent system used in this region for standalone structures, due to its availability, construction/cost efficiency, and durability.�

Frederick Avenue Bridge, Baltimore, MD

Frederick Avenue Bridge

Designers for the Frederick Avenue Bridge in Baltimore faced a challenge becoming more common today: The existing two-span, closed-spandrel wall-arch structure, built about 1911, needed replacement, and the community and Maryland Historic Trust wanted the new bridge to closely resemble the original design. To satisfy this request, designers used modern-day techniques with precast concrete forming to replicate the shape of the original arched design.

“Rather than design and construct another arch, it was decided to use prestressed concrete beams and provide an arch façade to give the appearance of the existing arch,� explains Mike Izzo, bridge department manager for Whitney Bailey Cox & Magnani LLC (WBCM). Historic concrete railings also were included in the $14-million project.

Precast concrete was chosen primarily to avoid having to shore the formwork needed to construct the arch, as the bridge crosses both an environmentally sensitive area, the Gwynns Falls, and tracks for the CSX Railroad. “Attempting to construct shoring over the CSX span would have been extremely difficult, if not impossible,� he says. Even so, designers had to create a system to span the tracks with the precast concrete components without shutting down service for an extensive period.

The precast concrete components were fabricated by Northeast Prestressed Products

Center 128 Parking Structure, Needham, MA

Center 128 Parking Structure

The large glass curtain wall surrounding the elevator and stair core in one corner of the seven-story Center 128 parking structure provides a signature look for the facility both during the day and night. It also created some challenges that the precaster had to solve aesthetically and structurally to make the design a success.

The challenges with the glass-enclosed stair and elevator tower arose due to the openness desired by the designers, explains Peter Bertolini, project manager at Blakeslee Prestress, the precaster. Some of the stair units required the internal columns to cantilever off support columns to provide the open look. “It required significant design and coordination for that element to meet what was required because of the desire to have nothing protruding into the area to obstruct the look.�

The precast concrete components were fabricated by Blakeslee Prestress Inc.

FEATURED LEARN AT LUNCH PRESENTATION

Precast Hollowcore Floors and Walls for Housing

Lunch & Learn-Hollowcore

In this program, participants will understand the basics of hollowcore plank flooring systems. Hollowcore is a common method of building multi-family and student housing, condominiums, and many other building applications. Fabrication and installation procedures will be discussed, along with proper detailing requirements. Building envelope considerations for energy efficiency, including fire resistance and acoustical benefits, will be reviewed. Several case studies will be presented. After viewing this program, participants will be able to identify the hollowcore plank systems and explain the benefits of using hollowcore plank systems with owners and other designers.
