Carbon Footprint Focus Of ASHRAE 2020 LowDown Showdown

this month

Earlier, ASHRAE recognized the 2020 LowDown Showdown modeling competitors teams. Held practically for the very first time with the virtual 2020 Building Performance Analysis Meeting and Simbuild co-arranged by ASHRAE and IBPSA-USA (International Developing Performance Simulation Association), the LowDown Showdown engages architects, engineers, designers, and power modelers by focusing on integrated groups in the development of outstanding styles that solve in real-world building efficiency problems. Because of this sixth annual competitors, carbon footprint had been the focus.

“Every year of the LDSd competitors, we ask participating groups to take on a fresh challenge in developing performance evaluation, said John Bynum, competitors chair. “The groups presented outstanding concepts for designing a fresh building which has a reduced carbon or carbon neutral footprint, this year’s task.”

This year’s competition took a full page from NY City’s new Climate Mobilization Act that will require building owners to lessen their carbon footprint. Participating groups designed a 300,000 square foot, 15-story mixed-use developing located in the 5 boroughs of NEW YORK anywhere.  The developing contained retail space, home room and a full-service eating place.

Groups were evaluated in 6 categories:

  • Carbon Neutral Method/Energy Use
  • Creativity
  • Innovative Approaches
  • Sustainability/Durability
  • Indoor Environmental High quality
  • Workflow and Teamwork

First Location: Team Aequitas

Initial place was awarded to team “Aequitas” for developing a net-zero-energy developing (shown above) that well balanced contextual neighborhood cues and useful performance. The building’s principal façade captured the look of close by warehouses.

For its 1st Place task, the Aequitas group, approached this mixed-use developing with the purpose of designing the Net Zero Energy developing with the holistic and integrated method of sustainability and resilience. Borrowing its architectural vocabulary from the nearby commercial area, the building’s main façade echoes the look of nearby warehouses. (Photograph: ASHRAE)

Useful elements that augment the building’s comfort and performance integrated narrow floorplates for sufficient daylight and ventilation, a dichotomous façade in the northwest that acts as an audio barrier to adjacent train and vehicle noise, and a diaphanous open up façade about the southeast, targeted at maximizing daylight and solar technology captured by way of a PV built-in window system. Resiliency actions were incorporated, HVAC techniques minimized usage of fossil mass and fuels timber was used as  the primary structural system, which at 15 stories made this building among the tallest bulk timber structures in THE UNITED STATES.

“Our developing integrates occupant comfort, functional and beautiful design, and healthy components, said Elizabeth LeRiche, group captain. neighbors and “Inhabitants can gather in outside green spaces and local community gardens, fostering bonds by way of a shared appreciation of foods production and our link with our collective effect on the environment.”

Second Place (Tie): Group Carbonbusters

A second-place group, “Carbonbusters,” chose an adaptive reuse style strategy restoring a brick strength plant that were abandoned, with a concentrate on energy conserving construction and sourced components locally. The task included geothermal wells (1,500 feet comprehensive) acting as a trusted way to obtain energy for cooling and heating, high-efficiency glazing to minimizes temperature energy and transfer reduction, a green roofing and public backyard and supplemental power creation using hydrogen.

Second Place (Tie): Group Parametric Posse Recharged

Also, the “Parametric Posse Recharged” team centered on using parametric design tools to strategically improve the performance of the building type regarding climate response, energy efficiency, carbon mitigation and occupant well-being. 3D façade has been included by the task providing exterior shading and aesthetic curiosity, a high-COP centralized GSHP program to provide hot/chilled drinking water to individual air-managing units in the flats and restaurant areas and sky gardens configured to lessen horizontal circulation.

Fan Favorite: Group Carbon Lighters

The fan favorite team, the “Carbon Lighters”, followed a tiered design process on a 41,860 square foot junk food chain drive-thru building. The task included a generous main courtyard configured to available to the East to capture the predominant southeastern summer season wind predicated on Brooklyn climate information, residential devices with access using one photovoltaics and side atop a continuing roof canopy.
