Abstract
Understanding building usage patterns and resource consump- tion, particularly for existing buildings, requires a sensing overlay onto the building infrastructure. Often, deploying these sensors and obtaining this real-time information is hin- dered by installation and maintenance diculties involving scaling down and powering these devices. Devices that rely on batteries are limited by the scale of the batteries and the maintenance cost of replacing them while AC mains powered sensors incur high upfront installation costs. To mitigate these burdens, we present a new architecture for designing building-monitoring focused energy-harvesting sensors that do not require access to mains power and do not need regular battery replacement. The key to this architecture is masking the inevitable intermittency provided by energy-harvesting with a trigger abstraction that can activate the device only when there is useful work to be done. In this paper, we describe our architecture and demonstrate how it supports existing energy-harvesting sensor designs. Further, we real- ize three additional design points within the architecture and demonstrate how the sensors are eective at building monitoring and event detection. The sensors, however, are classically disruptive: they improve ease of installation and maintenace, but to do so, they sacrice some delity and reliability. Whether this tradeoff is acceptable remains to be explored, but the technology needed to do so is now here.
