reACT uses & recycles low-value resources that would otherwise go to waste.
One principle of regenerative design embodied in reACT is that each element should perform more than one function, and that each function should be performed by multiple elements. This web of functionality is essential to resilience and adaptability. reACT achieves this goal through integration of passive and active systems throughout the house.
Engineering Active Systems: HVAC, Power, & Automation
The power system, comprising PV (photovolatic or solar power) modules, inverter (our is DC to DC current, so it converts voltage level), battery, and distribution system is arguably the most important mechanical system of the house. Apart from providing power to meet the demands of the other subsystems in a seamless and uninterrupted manner – particularly for critical systems – the power system must also be capable of regulating optimal battery charge levels in both the primary and electric vehicles to enable flexible choices in when to purchase or sell power to the grid.
Automation is controlled by a model-based (reACT Virtual House) supervisory control architecture. We developed this approach to optimize the house resources based on the objective of avoiding the need to micromanage all house functions. This strategy ensures fault tolerance of our system (the house will continue function in a default mode with the system turned off), that it will be minimally invasive, and it will maximize both potential for upgrades and compatibility with existing and future home automation technologies.
