Big data How can firms take the first steps towards applying big data methodologies in their AECO practices? by Daniel Davis and David Fano, CASE

f CO2 was the byproduct of the industrial revolution then data is surely the byproduct of the digital revolution. Data flows from nearly everything we do. We produce data when we send emails, take photographs, and check in with Foursquare. We produce data when we use our credit card, the internet and our GPS. And our buildings are producing data about their internal climate, about lighting use, and about room occupation and equipment utilisation. It is almost impossible to comprehend how much data we are producing. IBM estimates that we collectively produce 2.5 quintillion bytes of data in a single day (IBM 2012). To put that in perspective, the hard-drive in your computer probably accommodates one terabyte of data, which means we fill an equivalent of 2.3 million of those hard drives with new data every single day. Perhaps more astonishing than the amount of data is the rate at which our data

production is increasing. For all the data that exists in the world — all the data contained within all the books, and emails, and YouTube videos, and wherever else — 90% of this data was generated in the last two years (IBM 2012). Our data production has been steadily eclipsing itself and with the rate of data production increasing exponentially, in the not too distant future it will be eclipsed again. This might not sound like architecture. Big data — the name given to all of the data being collected and analysed — has traditionally been associated with marketing agencies, silicon valley startups, and intelligence organisations. But architecture is fundamentally about data. At the foundation of every BIM model lies data. Architects and engineers work to orchestrate data — creating it, modifying it, using it in simulations. Contracts take data and turn it into physical spaces, while building operators are increasingly managing
buildings using data from architects and from building sensors. Data underlies much of the modern AECO (Architecture, Engineering, Construction and Owneroperated) industry and we are only destined to produce more of it. Data alone does not make big data. In fact, ‘big data’ is somewhat of a misnomer since ‘big data’ does not have to be big. Big data is really about turning data into knowledge and wisdom; it is about metrics and analysis, insights and decisions. None of this requires a large data set, rather it requires an inquisitive approach and lots of statistical analysis. Given the amounts of data being produced by the AECO industry, there is a huge opportunity here, but it is one that not many firms are yet pursuing. At CASE we have been working with a number of our clients help them take the first steps towards applying big data methodologies in their various AECO practices. www.AECmag.com
