Facilities management and construction converge in a renovation project

European climate and energy policy has burdened building owners with the responsibilityto reduce greenhouse gas emissions. The recommendation in Finland is to improve energy efficiency in connection with other renovations when it is most effective as to costs and use of materials. Several decision-making models and tools have been developed to facilitate the path from devised strategy to completed renovation project. Improvement of the energy efficiency of the building stock and the consequent reduction in greenhouse gas emission has brought in more decision variables to consider and thereby new tools. The age composition of the Finnish building stock offers possibilities for energy renovations but due to changes in the operating environment and operations, and new demands on buildings, renovation projects must sometimes question the need for a building. This complicated decision making is the research question of this paper. Based on inquires and previous studies the decision tree is developed. It includes four main questions: Is there need for the building? Is the building technically worth renovating? What are the goals in renovation project? What is the best procurement model in this project? The research material consists of expert work shop and interviews. The project concretises the basis of the multiform body of decision-makers and decision-making. That is why the new-construction process model does not suit renovation very well. Facilities management and construction converge in renovation in a special way, which also builders should take into consideration.
