4th Annual ASHRAE LowDown Showdown

2018 Building Performance Analysis Conference and SimBuild
co-organized by ASHRAE and IBPSA-USA

September 26-28, 2018
Chicago, Illinois

The 4th Annual ASHRAE LowDown Showdown will be held in conjunction with the 2018 Building Performance Analysis Conference and SimBuild co-organized by ASHRAE and IBPSA-USA.


How Creative Are You?

Every year the LowDown Showdown has a new twist.  This year the competition calls on you to unleash your inner creativity (as well as your analytic skills) as you team up to model our most challenging building type to date.  

The focus of the 2018 Building Performance Analysis Conference and SimBuild is the adoption of new techniques and workflows to advance modeling and simulation to meet the growing challenges faced by today’s designers and modelers.  In that spirit, the 2018 LowDown Showdown challenges teams to go beyond just achieving an energy efficient building, and use their ingenuity to include elements of conference themes into their design and analysis.  In fact, getting to “near net zero” will be a part of the model building baseline.  That in and of itself will be a challenge, as the model building for 2018 is a 60,000 sf museum (new construction) located in Denver, Colorado and to include retail space and a full service restaurant. 

The goal of the 2018 LDSd competition is to engage participants in a collaborative and fun learning experience that explores new advances in building science, modeling and technology.

Each team will create and submit a poster of their building design, a performance analysis model and results spreadsheet, and write a one-page narrative on project workflow.  Participants will also be required to submit graphics to Project StaSIO, an online crowd sourced repository of modeling graphics and images.

Modeling and calculation workflow, building designs, systems and control strategies should be creative without being implausible from a cost standpoint.  To that end, one of the requirements will be a cost per square foot spending limit.  However, each team may include two (2) elements in its project that are not required to be included in the project costs.   Teams will be judged in two phases.  Phase 1 will be based on their initial entry.  Phase 2 judging will occur at the conference after teams have presented their projects. Teams will be judged on seven categories: Creativity, Innovative Approaches, Workflow, Energy Use, Calibration, Teamwork and Presentation. 

So get your creative juices flowing, start rounding up your team members and check back for our next update in February to include more information on the judging criteria and prizing!!
