POCKET CHANGE

INFLATABLE AIR CHANGE SYSTEM

8/2/2019 Ks2475 Midterm

2/44

PROBLEM:

Typical air distribution and conditioning systems are inefcient, expensive, and difcult tointgerate into a buildings design

Variable air systems often require additional conditioning

8/2/2019 Ks2475 Midterm

3/44

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

8/2/2019 Ks2475 Midterm

4/44

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

ELEMENT:

Inatable textile plenum that reduces room volume and distributes air basedon room occupancy

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
