• This Hydro Pavilion investigates the future of power generation through harvesting rainwater and seismic forces. By investigating the complex interaction of architecture and physics of power harvesting, the design end product is an interactive pavilion consists of sensors which monitors harvested rainwater and display the collected data to the public in the form of information and an art installation. The pavilion utilizes off-the-shelf sensors, actuators, and micro controllers, particularly Arduino. The concept is prototyped in a partial scale operational mock-up, integrating electrical circuitry, programming (using Arduino), and building elements. The responsive mock-ups is used to validate user experiences. The prototype explores the future technologies of large-scale piezoelectric sensors as well as compact hydro energy. The design scheme is expected to generate energy and clean water for the users as well as an architectural landmark with an interactive art installation.
