Private equity backed Albireo Energy LLC has acquired Sky Technologies Inc., a provider of energy-monitoring systems.

Sky, headquartered in New York, supplies energy- and power-monitoring systems and related services to data centers used by businesses, financial institutions, technology companies and education providers. Terms of the deal were not disclosed.

Albireo, headquartered in Edison, New Jersey, provides building automation and energy services. The company expects the acquisition to add to its energy efficiency and management offerings, as well as compliment building automation services. Albireo has made four acquisitions in the past 10 months: New Jersey-based Energy Options; California-based Electronic Control Systems; and Green Total Solutions, also in California.

The buyer was founded by Huron and industry executive Phil Bomrad  in 2014 to provide energy service and smart building services to commercial and institutional customers in the U.S. 

The buyer is backed by Detroit private equity firm Huron Capital Partners LLC. Huron's Gretchen Perkins was named Mergers & Acquisitions M&A Mid-Market Dealmaker of the Year for 2014. The firm has been involved with several deals lately, including portfolio company Ronnoco Coffee LLC's acquisition of U.S. Roasterie Inc. in February, and Huron-backed Hughes Associates' merger with RJA Group in June.

Huron isn't the only group interesting in building-services deals – in January, Robert Bosch North America Corp. bought Climatec LLC, which provides energy efficiency, building automation, security and other services for building owners.
