Forum — Performance of Dynamic Façades
“The essential roles of the building facades—providing shelter, form, and image—can be expanded to significantly improve building performance, including major reductions in energy use. Rather than a static enclosure, the building facade has the potential to redirect daylight, integrate natural ventilation, manage radiant heat transfers, generate energy, and provide visual and physical connections between inside and out. High performance, dynamic facade design can be realized in new construction and in strategic retrofits of existing buildings. Supported by HiPE lab and Oregon BEST, this project is intended to guide students/young professionals in a year-long investigation of a dynamic facade component leading to a scaled prototype construction and testing of this component. Objectives for the design of this component are:
1. Enhancing transparency and aesthetics from the outside in as well as inside out.
2. Harvesting and redirecting daylight deeper into the building
3. Managing glare and brightness patterns for occupants’ visual comfort
4. Solar control management for improved thermal comfort
5. Provide opportunities for ventilation and control heat gains/losses
6. Improved materiality/details and opportunities for scaling to multiple applications
Phase I, of the project was broken into six weekly sketches/investigations covering specific design parameter(s) of the facade design/prototype. Teams developed facade protoypes for a representative bay of a typical commercial building typology, initial design concepts, sun-angles and rule-of-thumb techniques. The schemes were based on a single-sided one-floor bay, 20 ft. wide and 30 ft. deep of a south-facing commercial office building
In Phase II, teams constructed a full-scale prototype of a portion of the bay or a scaled-down bay to fit within a 53”x95”experimental bay situated on the FIT facility. In Phase III, the performance and analysis of the results from data collected via the FIT facility portal as well as simulation and scaled models studies were analyzed and documented for each prototype and in-between protoypes.
The forum will report on this year long investigation. A theoretical overview of Dynamic Facades taxonomy and attributes supported by contemporary case studies will be presented. This will be followed by application and demonstration of the performance of six different prototypes of dynamic facades covering thermal, optical, and integrated typologies of dynamic facades and material applications in an interactive session. The forum will conclude with future research and applications recommendations as well as lessons learned to ignite future generations of students and professionals in active envelopes research and tectonics.”
