EventsSoFi Stadium and Hollywood Park
Friday, October 30 | 9:00 AM PDT
Lee Slade, PE, M.ASCE
Rafael Sabelli, SE, M.ASCE
Director of Seismic Design
SoFi Stadium is an unprecedented and unparalleled sports and entertainment destination being built in Inglewood, CA. The first indoor-outdoor stadium to be constructed, SoFi Stadium will be the home of the Los Angeles Chargers and Los Angeles Rams when it opens in summer 2020. The state-of-the-art stadium will host a variety of events year round including Super Bowl LVI in 2022, the College Football Championship Game in 2023, and the Opening and Closing Ceremonies of the Olympic Games in 2028. Located on the site of the former Hollywood Park racetrack, the stadium is the centerpiece of a 300-acre mixed-use development featuring retail, commercial office space, a hotel, a performance venue, 2500 residential units, and outdoor park spaces. This $5 Billion project is the largest active development in California.
- Innovative structural design of the retaining walls and stadium canopy foundations including the seismic design considerations. The canopy struts extended outwardly from the stadium underneath public streets, thus creating challenging re-rerouting of existing and proposed utilities. Sophisticated 3-D modeling was used to resolve utility and strut conflicts.
- Project workflow techniques that accommodated owner-initiated revisions while maintaining the aggressive project schedule.
- Hydrologic modeling and drainage design that adapted an existing man-made lake to a combination water quality / stormwater detention / project amenity. This helped the project comply with stringent agency standards for stormwater quality and quantity.
Facade Retrofit: Recladding Strategies to Boost Performance
Thursday, November 5 | 9:40 AM CST
Dirk Kestner, PE, LEED AP, ENV SP (Moderator)
Director of Sustainable Design
Rachel Calafell, PE
Across the country, cities are experiencing spates of new development. Nestled within these same urban areas, however, are legacy “architectures” spanning myriad typologies and waiting to be adapted for contemporary use. This panel will highlight two case studies that exemplify this trend and attest to the technical intricacies of breathing new life into historic structures.
Modeling Lifetime Carbon: Operations+Embodied+Transportation
Tuesday, November 10 | 2:00PM CST
CE Hours: 1.5
Kelly Roberts PE, LEED AP BD+C
Suboptimization of carbon reduction strategies is unavoidable when significant portions of a project’s greenhouse gas (GHG) emissions are ignored.
Traditionally building energy performance in energy codes and rating systems have used energy cost metrics. Net zero definitions typically use annual energy consumption as a metric. Some codes and standards are moving toward energy use intensity. Occasionally building energy use is converted into GHGs with annual emissions factors. With electrical grids decarbonizing and regionally varying based on seasonally available renewables, hourly grid emissions data are better predictors of energy consumption-related GHGs.
Meanwhile as net zero codes reduce building energy use, the carbon emissions related to the construction materials increase as a percentage of the project’s overall GHGs. This has raised awareness of embodied energy and carbon. Nevertheless, too few are utilizing these tools to reduce their carbon footprints which largely occur during construction.
Transportation emissions can easily eclipse both operational and embodied carbon, yet project’s transportation-related emissions are rarely attributed to the property, which undermines the importance of location efficiency. Transportation alternatives vary across every metropolitan region. Electric vehicle uptake will also vary geographically. LEED Zero Carbon is a rare exception with the inclusion of transportation-related emissions, but the rating system is only applicable to existing buildings, when the projects are out of the designers’ control.
Designers need tools to assess all their projects’ lifetime GHG emissions prior to construction to make informed decisions regarding choices which have larger impacts on reducing carbon emissions related to the built environment. Excluding any of these components in a net zero definition, risks suboptimization at the expense of the possibility of a more climate-responsive design. Our panel will review methodologies with examples to assess all these elements over a 30-50-year timescale during the design phases of a project to Design for LEED Zero Carbon.
- Grasp how electrical grid decarbonization will vary emissions over time--hourly to annually and from region to region--while learning the distinction between average emissions and marginal emissions.
- Learn how to apply hourly electrical grid emissions profiles to energy models’ hourly results to create annual and lifetime building energy use carbon emissions (included in LEED Zero Carbon).
- Discover tools and methods to assess the location efficiency and transportation energy intensity of a given project site for a proposed project type (included in LEED Zero Carbon).
- Understand life cycle assessment (LCA) methodology and available Whole Building LCA tools to identify strategies to reduce embodied carbon on projects (not currently included in LEED Zero Carbon).
Structural Engineers make the Commitment: Launch of SE 2050
Thursday, November 12 | 1:30 PM CST
CE Hours: 1
Dirk Kestner, PE, LEED AP, ENV SP
Director of Sustainable Design
This session explains the newly launched Structural Engineers (SE) 2050 Commitment Program by the Structural Engineering Institute (SEI) of the American Society of Civil Engineers (ASCE). SE 2050 is a national program with goals of reducing the embodied carbon of our structural systems to net zero by 2050 through education, tracking of embodied carbon, and establishing reduction targets over time. Modeled after the AIA 2030 Commitment, this program focuses on tracking and reducing embodied carbon in structural framing systems. SE 2050 is the only national embodied carbon program focused on structural framing systems and their relationship to climate change.
An introduction of the SE 2050 database used to track embodied carbon will be included and the embodied carbon differences of various structural system types and materials will be presented. We will show how structural-engineer-supplied material quantities and embodied carbon impacts supplied in the pilot-phase of the program were used to establish benchmarks or target values for various structural materials and systems. We will review how achievable embodied carbon targets will be determined and reduced over time to achieve zero net embodied carbon by 2050. Solutions to the challenges associated with current and emerging building materials to achieve the goal of net zero embodied carbon will be presented.
We will provide insight into how to engage your structural engineer in climate change and how we are securing structural engineering firm commitments. We will provide highlights of the embodied carbon action plan that committed firms must produce upon signing up and how we feel it will lead to substantive embodied carbon reductions. Finally we will give an overview of how SE 2050 aligns with other climate change initiatives, including LEED Zero, the LEED v4 BD+C Materials and Resources Building Life Cycle Impact Reduction credit and changes in v4.1, plus newer embodied-carbon pilot credits.
- List 5 ways you can engage your structural engineer in embodied carbon reductions.
- Learn embodied carbon reduction targets associated with embodied carbon programs, including SE 2050.
- Estimate the embodied carbon intensity for various structural framing schemes in different parts of the country.
- List 5 ways you can reduce the embodied carbon of your structural framing system.
