Abstract
The paper presents cost-effective energy performance improving measures in a Finnish (cold climate) detached house built in the 1980’s. The studied building represents a typical relatively energy efficient Scandinavian detached house with direct electrical heating system. The main objective of the research was to study and compare the cost-effectiveness and energy performance of modern renewable energy production systems and different HVAC systems in addition to the more traditional energy performance improving measures. The research method of the study was simulation-based multi-objective optimization, which was used to minimize the life-cycle cost and the total energy consumption of a case study building. The air-to-water heat pump system with water-based floor heating system in all spaces, combined with additional thermal insulation of roof and new air handling unit with improved heat recovery system (75-80 %) proved to be the global cost-optimum solution. All of the studied heat pump systems and the original direct electrical heating system proved to be more cost-effective main heating systems than the district heating system.
