TRACK A Environment

Combined with growing expectations for high performance, building enclosure design is now required to satisfy a large number of performance parameters that were not given a great deal of consideration in the past. Building enclosures were always expected to be durable and address issues like energy efficiency, daylighting, indoor air quality, fire safety, thermal comfort, and carbon footprint, but now with aggressive changes in code and the climate crisis the urgency to decarbonize our building envelopes and radically reduce operational carbon is every designers responsibility.

TRACK B Performance and Detailing

Clients demand attractive and high-performing buildings and as designers, you need to zoom in on fundamental design principles to achieve performance goals. This track will feature the opportunity to detail and collaborate on high-design, and high performance facades.

10:00 - 12:00 PM

This two-hour workshop will provide an overview of load paths, jointing, and tolerances in exterior enclosures. The workshop will begin with a lecture on the basics of load paths, including how loads are transferred through a building structure. The lecture will also discuss the different types of joints used in exterior enclosures, as well as the factors, such as tolerances, that need to be considered when designing and detailing joints.

The second half of the workshop will be an interactive whiteboard exercise in which participants will work with the presenters to develop solutions to a handful of specific details. This exercise will give participants the opportunity to apply the concepts they learned in the lecture and to gain experience in working with tolerances and building movements.

Learning Objectives:

  1. Understand the basics of load paths in exterior enclosures
  2. Identify the different types of joints used in exterior enclosures
  3. Understand the factors that need to be considered when designing and detailing joints
  4. Develop solutions to specific details that take into account load paths, tolerances, and building movements.
Audience:  This workshop is intended for architects, engineers, contractors, and other professionals who are involved in the design, construction, or maintenance of exterior enclosures.
Materials:  Whiteboard and markers, AV equipment

It’s hard to build large-scale buildings, and nearly all are delivered over budget and behind schedule.
Capital projects require the coordination and assembly of thousands of physical parts, driven by Building Information Models [BIM]. Whether parts are prefabricated, stick-built, or 3d printed is of little consequence — the reality is that they all need to be combined by field crews on-site.
However, as buildings are erected, accumulation of part and assembly tolerances, thermal movement, deflection, creep, error, etc. mean that physical as-builts structures geometrically diverge from digital models (often in significant ways). As construction continues, these deviations often create multi-trade coordination problems and confusion about what is being built. Pre-planned documentation (BIM) doesn’t properly inform installation activity because it only represents the nominal/theoretical condition, not real life. This leaves field installation crews the difficult job of interpolating part positions from partial ad hoc as-built measurements. Construction sites are dynamic —construction planning must be reactive and recursive!
3D modelling is often considered a task that takes place exclusively during the planning phases of a project. This is a missed opportunity and misconception. We argue that 3D modelling is even more critical during execution phases when used as a feedback loop from job sites and leveraged to understand onsite conditions and direct on-site activities. Utilizing survey data and as-built point clouds, we deploy iterative solvers to digitally “test fit” and “best fit” parts in a process we’ve deemed Reconciliation Modelling. Using the specified adjustability (tolerance) of anchor points as parameters, a design space of all potential install positions can be constructed and evaluated. This design space provides both optimal install positions based on as-built conditions and flags areas where field installers cannot be successful, long before crews arrive at the job site.
Real-time, reactive decision making, rather than pre-planning, is transformative to the construction market as it allows the construction process to be resilient to changing site conditions and tolerant of inevitable perturbations during building construction.

TRACK C Materials

Material selection not only impacts aesthetics but the delivery and performance of a building. These deep-diving case studies will discuss working with materials such as terra-cotta, mass timber, and more with lessons learned through real world case studies in both ground up and adaptive reuse scenarios.
