As more and physical information becomes available, a critical problem is enabling the simple efficient exchange of this data. We present our design for RESTful web service called Simple Measuring Actuation Profile (sMAP) which allows instruments other producers to directly publish their In study, we consider what should be represented, how it fits into paradigm. To evaluate sMAP, implement large number data sources using profile, easy use build new applications. also set adaptations made at...
Commercial buildings consume nearly 19\% of delivered energy in the U.S, half (42%) which is consumed with digital control systems comprised wired sensor networks. These sensors have scant metadata, and are represented by ``tags'' obscure, building-specific not machine parseable. We develop a human-in-the-loop synthesis technique uses syntactic data-driven steps to parse these tags into common namespace, can enable portable building applications. show that our allows an expert fully large...
Emerging hybrid chips containing cpu and FPGA components are an exciting new development promising commercial off-the-shelf economies of scale, while also supporting hardware customization.
A typical large building contains thousands of sensors, monitoring the HVAC system, lighting, and other operational sub-systems. With increased push for efficiency, operators are relying more on historical data processing to uncover opportunities energy-savings. However, they overwhelmed with deluge seek efficient ways identify potential problems. In this paper, we present a new approach called Strip, Bind Search (SBS); method uncovering abnormal equipment behavior in-concert usage patterns....
Building analytics can produce substantial energy savings in commercial buildings by automatically detecting wasteful or incorrect operations. However, a new building's sensing and control points need to be mapped the inputs of an engine before analysis is feasible process mapping highly manual - key obstacle scaling up building analytics. In this paper, we present techniques perform automatic without any intervention. Our approach builds on improves upon from transfer learning: it learns...

Most large, commercial buildings contain thousands of sensors that are manually deployed and managed. These used by software firmware processes to analyze control building operations. Many such rely on sensor placement information in order perform correctly. However, as evolve subsystems grow change, managing becomes burdensome error-prone. An automatic verification process is needed. We investigate empirical methods automate spatial verification. find a clustering algorithm able classify...
In this paper, we model energy use in commercial buildings using empirical data captured through sMAP, a campus building portal at UC Berkeley. We conduct at-scale experiments newly constructed on campus. By modulating the supply duct static pressure (SDSP) for main air duct, induce response fan and determine how much ancillary power flexibility can be provided by typical building. show that consequent intermittent fluctuations mass flow into does not influence climate human-noticeable way....
Buildings account for a large portion of the world's total delivered energy consumption. With smartphones becoming increasingly ubiquitous and sensor networks growing more mature, buildings can provide personalized context-aware services to an occupant while minimizing This paper proposes architecture Human-Building-Computer Interaction system that connects building its occupants by bridging gap between digital physical worlds. We present our instantiation HBCI system, which is composed...
We study the utility of dynamic frequency agility in real-world wireless sensor networks. Many view such as essential to obtaining adequate reliability industrial environments. quantify actual by identifying two facets connectivity graphs that yield potential benefits called Multichannel Links (MCLs) and Triangles (MCTs), how frequently these occur empirically determine whether multihop provides a comparable solution without complexity switching channels. examine live networks over each...
Office buildings contain large sensor network deployments to monitor and maintain their internal environment. They also consume a significant amount of energy. This paper proposes the use horizontal layering, rather than current vertical-solution approach, expose building data plane enable interoporable software services applications that control We present our instantiation this which includes (sMAP) storage service (IS4). Furthermore, we describe set built in ecosystem.
In this paper we present Beacon Location Service (BLS): a location service for beacon-based routing algorithms like Vector Routing (BVR) [8] and S4 [19] . The role of is to map node names topologically meaningful addresses that can be used routing. We evaluate an implementation BLS works on top BVR. resolves the destination node's name BVR coordinates then uses route source message node.
Popular sorting algorithms do not translate well into hardware implementations. Instead, hardware-based solutions like networks and linear sorters exploit parallelism to increase efficiency. Linear sorters, built from identical nodes with simple control, have less area latency than networks, but they are limited in their throughput. We present a system composed of multiple acting parallel order Interleaving is used bandwidth allow values per clock cycle, the amount interleaving depth can be...
Extracting meaningful information from a building's sensor data, or writing control applications using the depends on metadata available to interpret it, whether provided by novel networks legacy instrumentation. Commercial buildings comprise large networks, but have limited, obscure 'tags' that are often only facility managers. Moreover, this primitive is imprecise and varies across vendors deployments.

Time-series data gathered from smart spaces hide user's personal information that may arise privacy concerns. However, these are needed to enable desired services. In this paper, we propose a preserving framework based on Generative Adversarial Networks (GAN) supports sensor-based applications while the user identity. Experiments with two datasets show proposed model can reduce inference of identity inferring occupancy high level accuracy.
