According to IBM, smarter buildings will be able to use resources more intelligently, which will lead to reduced costs and greenhouse gas emissions and ultimately to smarter, more efficient cities. Their Smarter Buildings team helps customers "listen to the enormous amounts of data" their buildings are generating. By listening to this data through embedding smarter technologies into the physical assets of an organization, building owners, facility managers and other stakeholders can analyze energy use to squeeze out inefficiencies.
Groups of buildings will mimic living systems. Neighborhoods are the building blocks of smarter cities, which are just systems of systems—water, power, transportation, etc. Like a living system in nature, they can be highly complex, especially when considering the conglomeration of infrastructure over a city's 100- to 200-year history. In Washington, D.C., water pipes date back to the Civil War, for example. A neighborhood is a microcosm of the city; to make a city smarter, starting at the neighborhood level is more manageable. IBM is working to help the community become early adopters of smart grid technology that will electronically monitor, analyze and minimize power consumption in residential and commercial buildings—as well as of on-site solar and other clean-generation systems.
Occupants of smarter buildings will get better visibility into building’s functions, such as how much water and energy they are using. Most businesses and residents now find this out by looking in their rear-view mirror—the previous month's utility bills. With smart meters, residents and businesses are getting closer to real-time views into their actual usage. With smarter buildings technology, building managers have a cross-building view into actual performance of all systems so they can make adjustments and repairs when needed, a key step when looking at large facilities, campuses and cities. Using analytics provides deeper, X-ray vision into what's happening in real time.
As buildings and cities are instrumented, managers will rely more on analytics to flag outlying behavior and to recommend optimal settings for heat, water and other facility maintenance. Predictive maintenance will become condition-based. At its 3.2-million-square-foot Rochester, Minn., campus, IBM integrates data from more than 300,000 data points, consolidating it into a common repository for effective analytics. Through this solution, the Rochester facility cut energy use by 8 percent, on top of the 6 percent reduction already being driven through aggressive energy-improvement programs.
Applications that pull data from a building and a city's "Internet of things" will proliferate. Parking applications can help drivers find available parking spots, for example. But it goes beyond that. The Internet of things gives people information, the first step toward making change. Through the increasing connectivity, people can act as living sensors to provide data and feedback to make changes and create smarter cities and buildings. For instance, some cities are extending that Internet of things to city services such as enabling citizens' to alert cities to potholes, graffiti and water issues by taking photos and sending them to city management, where they can be prioritized and dealt with. Cities are using geospatial intelligence to send crews with the information they need and the overview of where the projects are to map out the best driving routes.
Now Serving at the Energy Cafe
Building managers will order from a menu of energy, allowing them to choose energy by source and/or cost. Just as shoppers can chose which type of produce they want based on cost and source, city and building managers will be able to do the same with energy sources. With smart meters, building occupants know how much energy they are using. However, organizations in the future will also be able to choose the source of their energy. If they have carbon footprint targets to meet, they can decide to get 30 percent of their energy from renewable sources like solar and wind. If that gets too costly, they can shift more to natural gas.
Real Estate Management Becomes a Science
A company's finance/real estate team is evolving into a smarter buildings team. In the next few years, accounting changes will require all publicly traded companies to add billions in new assets to their balance sheets. As organizations begin to itemize all their property assets, they'll also look into ways to reduce costs. What they're discovering is that by learning how their buildings are wasting energy, they are finding new ways to cut costs and reduce their carbon footprint. The cost of energy use in New York City municipal buildings totals more than $800 million each year and accounts for about 64 percent of the greenhouse gas emission produced by government operations. With carbon intelligence software, the city is aiming to reduce its greenhouse gas emissions 30 percent by 2017.
