IBM has completed the acquisition of privately-held TRIRIGA, Inc., a Las Vegas, Nevada-based software company to expand IBM's smarter buildings offerings with advanced intelligence on facilities and real-estate performance.

The acquisition of TRIRIGA will help accelerate IBM's growth in the smarter buildings market, a key initiative in IBM's Smarter Planet initiatives, says the company.  At IBM's recent financial analyst meeting, IBM said Smarter Planet projects are estimated to drive $10 billion in revenue for IBM by 2015. The worldwide market for smart buildings is expected to grow 25 percent annually from $3.9 billion in 2011, according to IDC.

IBM expects that combining TRIRIGA’s software with its own smart buildings solution will provide "the industry's most comprehensive offerings to give organizations a single ‘command center’ for buildings’ operations worldwide – from managing real estate portfolios, energy usage and equipment efficiency in a range of buildings -- office buildings, warehouses, campuses, resorts and cities."

Tririga is already used by more than one-third of Fortune 100 corporations across every major industry and public sector, including, Nokia, GE, Canadian Tire, US Department of Homeland Security and Gap.
