Granlund’s history in brief

Read about our growth from a small engineering office to an international forerunner in energy efficiency and digital solutions.


The engineering office “Insinööritoimisto Olof Granlund Antti Oksanen” is founded in central Helsinki. The first CEO of the company was Olof Granlund.


In five years, the company grows from 7 to 48 employees.

Late 60s

Projects in the 60s included HVAC engineering for hospitals, public shelters and sites for the Ministry of Defense.

Early 70s

The first computer programs are taken into use at Granlund’s office. Projects include subway stations and industrial projects.


The 1979 oil crisis drives Granlund to start offering energy analyses for buildings. This can be regarded as the beginning for the company’s aim to make buildings more energy efficient.


Service offering is expanded to all areas of building technology.


Reijo Hänninen begins as the second CEO of Granlund.


Olof Granlund retires, giving up his ownership to five long-term employees. The 90s was the beginning for the Granlund partnership model as the number of shareholders increased up to twenty employees.


Granlund starts developing a property management software that was the predecessor of the software Granlund Manager.


Granlund continues to focus on digital tools, completing its 500th building information modelling project in 2004.


An own department for energy and environmental management services is introduced. The third CEO of the company, Pekka Metsi, starts in his position.


Granlund starts to grow through several acquisitions and organic growth. Also the partnership model strengthens as the number of employee shareholders grows remarkably.


Granlund is a company owned by almost 300 shareholders, who are all Granlund employees. The company has offices all around Finland as well as in Sweden and the UK.


Granlund aims for strong growth and internationalisation by strengthening its ownership base through the addition of a new international owner. The majority of the ownership will remain to the shareholders of Granlund, and the investment company ICG comes in as a minority investor.
