Use of Big Data in Smart Buildings

  • 23/06/2023

The Big Data phenomenon is exposing the market and altering how we manage data as we ride the wave of device connectivity to the cloud giving a wealth of data. A new data architecture is emerging, which is challenging the paradigm of classic logical database management tools. Some of the fundamental architectures driving the concept are MapReduce, Hadoop, Chukwa, Ambari, Hive, Zookeeper, Cassandra, and Mahout. They are revolutionizing data management in the Information and Communication Technology (ICT) business by providing faster data access for visualization to the right audience at the right moment. Is it time for Big Data in the BAS market, or can BAS data be evaluated before entering the big data realm, or is a hybrid solution available? This article investigates the concept of big data and how classical machine learning techniques can be employed in smart devices to propose a hybrid strategy for managing data in a building automation system.

Unstructured information is everywhere

Big Data is the term used to represent a collection of complicated data that is challenging to process with conventional database management techniques. Capturing, storing, searching, sharing, transferring, analyzing, and visualizing are all included in the processing. The recent development in unstructured data from mobile devices, sensing technology, wireless sensors, social networks, satellite pictures, photo/video, and speech, as well as the decline in storage costs, have all contributed to big data’s enormous growth in data sets. As a result of the restrictions the existing rational database technology faces in acquiring the appropriate data at the appropriate moment, alternative database architectures like MapReduce and Hadoop have emerged. Processing unstructured data is the underlying advantage of modern big data platforms. Structured datasets with relationships were necessary for the traditional database tools to process the data. However, fast processing of unstructured data is made possible by architectures like Hadoop and MapReduce. Big problems can be broken down into smaller components using Hadoop, allowing for speedy and efficient analysis. It is a flexible, dependable, clustered method of handling files in a big data setting. Given the ever-growing amount of unstructured data in our daily lives, this architecture has been a significant advancement in data management.

Hybrid Solution to manage data in the BAS industry

BAS companies benefit from big data architecture. Smart buildings use sensors and wireless and wired networks to collect infinite data from essential resources. A central processing unit analyzes and visualizes data. Over the last two years, several firms have entered the dashboard business with various data visualizing panels due to the increasing rise of building data. The BAS sector needs big data architecture to process unstructured data as data grows. Players should not assume that big data architecture is the only future data-handling solution for smart buildings. The BAS industry captures data from vital resources to smart devices before processing it in a database or data warehouse. The smart device can do much more. Smart has been the ICT buzzword for the past decade. Are devices smart? BAS smart controllers. It receives sensor network data and takes action according to program logic. A database stores the data for analysis and mining. Is it smart? No, the BAS controller has done so for 20 years. Implementation is unchanged. Changes are needed to use cheap flash technology to store raw data in the device and perform analysis on the fly to take proactive action on important resources it monitors or controls. Neural networks, fuzzy logic, and data mining are established AI solutions that can be utilized in the device to machine learn and make proactive decisions to increase resource performance. The PID loop controls an output based on input and set point and requires user input to tune its settings. Many integrators or users lack the technical abilities to set these parameters, causing them to malfunction and waste energy. The product may have great features, yet human error can break its core functionality. The gadget should have an adaptive PID control loop that learns from prior data to alter its parameters without user intervention. Without sending data to a huge data warehouse application, historical device data can achieve such effects. To develop a smart device and distributed system, learning programs can respond to energy usage patterns and make proactive local device decisions. The device’s historical data can be exported to an external application for big data architecture-based long-term analyses. Smart gadgets can make quick decisions without external apps.

Frequently asked questions:
