IBM (NYSE: IBM)’s push for its “Smarter Planet” initiative is adding more capabilities to its “smart buildings” portfolio of offerings.

Big Blue, which employs some 10,000 people in the Triangle area, said Tuesday it is acquiring privately held Tririga, a provider of facility and real estate management software.

Financial terms were not disclosed.

The Las Vegas-based company works with clients on sustainability planning and programs.

“The combination of TRIRIGA and IBM smarter building solutions will deliver the industry’s most comprehensive capabilities that span the needs of all industries for managing facilities and real estate portfolios,” said Florence Hudson, energy and environment executive at IBM. “Having one view of building operations worldwide will be a powerful tool to help organizations control and optimize their second-largest corporate expense – property.”

Tririga has some 200 clients, including more than a third of the Fortune top 100.
