Leveraging Physical Locality to Integrate Smart Appliances in Non-Residential Buildings with Ultrasound and Bluetooth Low Energy

alt text In this project, we are exploring new ways in how IoT devices should be connected locally and to the Internet, and how we can ease the local access of such smart appliances through sound-based localization in the context of non-residential buildings. Smart appliances and sensors have become widely available. We are deploying them in our homes to manage the level of comfort, energy consumption or security. While such smart appliances are becoming an integral part of modern home automation systems, their integration into non-residential buildings is problematic. …

Human-in-the-loop BMS Point Matching and Metadata Labeling with Babel

alt text In this project, we work on solving the problem of inconsistent Building Management Systems (BMS) metadata in non-residential buildings through crowd-sourcing the building occupants. Inconsistent BMS metadata hinders the deployment of novel cyber-physical applications. The reasons that make non-residential buildings a prime candidate for cyber-physical applications are numerous: These buildings account for a major share in energy use in Western countries, while the average person spends a long time inside them. …

BUSICO3D

alt text With BUSICO3D, we developed a system that provides: (i) a virtual representation of a building as a more natural interface for human interaction, and (ii) an integration of simulation and control that allows the testing of configurations without any harm on the physical building or personal environment (see Figure 1). BUSICO3D uses sMAP as an abstraction layer for accessing and describing various sensors and actuators of the physical building. The structure of the physical building is derived from an imported BIM (Building information modeling) model. …

COSMGrid

alt text COSMGrid is a microgrid platform based on commodity hardware and open source, open protocol software. The design of COSMGrid relies on a network of microcontrollers that monitor and control stand-alone power generation and storage nodes. As a result, COSMGrid can readily integrate existing stand-alone photovoltaic installations. COSMGrid can be configured based on the characteristics of the power electronics hardware that is available, or based on the power sharing policies agreed upon by a community of end-users. It is an important step towards a popular, open microgrid solution that can be appropriated by local communities in developing regions.

Node Benchmarking

alt text Sensor networks require sensor nodes. The energy available for the operation of these nodes is often limited. Nodes are battery powered or run of energy harvesting technologies like solar or motion. An optimization of energy consumption of these nodes is therefore crucial. We have developed a platform to perform these performance tests.
