ATLANTA (February 17, 2020) – ASHRAE is inviting individuals and project teams to participate in the 6th Annual ASHRAE LowDown Showdown (LDSd) modeling competition, taking place at the 2020 Building Performance Analysis Conference and SimBuild on August 12-14, 2020, in Chicago, IL. The 2020 BPACS is co-organized by ASHRAE and IBPSA-USA. Sign up for the competition as a team or individually at by March 6, 2020.

The ASHRAE LowDown Showdown modeling competition engages teams comprised of building analysts, designers, architects and engineers in a collaborative and fun learning experience that explores new advances in building science, modeling and technology. Participants work as integrated teams to create effective workflows and an outstanding designs to address real-word building efficiency challenges. 

The 2020 LDSd model building will be located in New York City where participating teams will design a 300,000 square foot, 15 story mixed-use building located anywhere in the five boroughs. The building will contain retail space, residential space and a full-service restaurant. 

“Each year of the LDSd competition, we ask participating teams to take on a new challenge in building performance analysis,” said John Bynum, chair of the LowDown Showdown sub-committee. “This year, we’re taking a page from New York City’s groundbreaking new Climate Mobilization Act that requires building owners to reduce their carbon footprint. The 2020 LDSd will challenge participants to design a new building that has a low carbon or carbon neutral footprint.”

Teams will be responsible for creating the architectural design and a performance analysis model based on model building data. The teams may use any software or a combination of software to complete their projects.

Each team will create and submit a poster of their building design, complete the performance analysis model and results spreadsheet and write a one-page narrative on project workflow. Teams will present their projects at the BPAC conference and be judged by a panel of industry experts who will select the winners. Teams will be judged on seven categories: Creativity, Innovative Approaches, Carbon Emissions, Workflow, Energy Use, Teamwork and Presentation.
