PROBLEM:
Typical air distribution and conditioning systems are inefcient, expensive, and difcult tointgerate into a buildings design
Variable air systems often require additional conditioning

DESIGN GOAL:
Activate the ceiling as a space for improved design and air control
Improve quality of life of interior spaces by increasing level of design and thermal comfort

MECHANICAL PRECEDENTS:
Porous textile ducts and diffusers
Benets:
Problems:
Flexible, efcient, less expensive than metal ductwork
Require same mechanics as typical ductwork and causes visual interruption

GREEN CODE COMPLIANCE:
GOALS AND BENEFITS:
-More efcient air exchange (more consistent coverage and distribution)-Higher aesthetic value:
-Material and form variability- Translucent materials allow light to diffuse through system
-Cheaper materials and installation-Flexible system
-Modules be easily (re)moved for maintenance or redesign-Reduced room volume requires less conditioning (lower CFM)-Dual duct system reduces need for additional heating/cooling loads
-More efcient diffusion + reduced room volume + cheaper materials andinstallation= less energy expended --> cost savings
