The aims of this thesis were to evaluate how Skanska Hus Norr works with energy audits in housing projects and provide improvement suggestions in that area. The evaluation was conducted through interviews with two property management companies in Uppsala. We also interviewed managers and energy engineers at Skanska to review the use of internal resources and evaluated if these resources can be used more efficiently. The results show that Skanska Hus Norr fulfill all the necessary prerequisites to perform thorough energy audits in housing projects. The study also shows that one of the problems is lack of time for project and production managers. The conclusions of the thesis recommend Skanska Hus Norr to schedule follow-up meetings regarding energy and to hire a person who can act as energy coordinator.
