Nature provides the models for energy solutions.
Intrinsic reactive structures will fundamentally change how we control our micro environments.
Control and Management of
Lighting, Temperature, and Humidity
Reactive Laminate Actuation
The basic principal is that a layered structured material can be engineered to produce a desired mechanical reaction to a change in environments; thermal, chemical, electrical, and radiant.
A Single Example of Biomimicry: Stomata for Buildings
Humidity Reactive Ventilation
Example Reactive Actuator: Humidity Sensitive
Forced Air Flow Through An Actuating Valve
Constant pressure air flow through and actuating flap valve
Actuating flap valve that opens with high humidity and closes with low humidity.
The flow rate for 90% relative humidity was six times higher than at 19% relative humidity.
Respond to temperature to change ventilation
Effects of Temperature on Plants
Leaf unfolding rate increases as temperature increases
If temperature exceeds the maximum temperature development declines due to stress
Temperature and Humidity Control in Green Houses
Humid Environment of Green House
Ventilation: Controlling Temperature and Humidity
Temperature Sensitive Apertures
Open when Hot
Closed when Cold
Sealed Top vs Aperture Vent Greenhouse
