Impact of the implementation of energy saving measures on the life cycle energy consumption of the building

Abstract

Energy efficiency improvement becomes a priority field of the European Union energy policy. In Lithuania the biggest energy saving potential exists in buildings. While renovating the buildings couple of problems are solved: reduction of energy consumption, restoration of premises comfort conditions, improvement of buildings physical state and also cost-effectiveness of the applied measures. Energy consumption in a building can be decreased to the minimum level while introducing the state-of-the-art measures. But it is not always reasonable. Goal of the research is to propose a methodology and according to the proposed methodology to estimate energy saving measures implementation impact on the life cycle energy consumption of building. Research results are presented via the exact example of the existing school building. While selecting energy saving measures, energy savings are estimated and cost-effectiveness of the implemented measures is calculated.
