Energy efficiency of buildings
VTT promotes the control of climate change, the use of renewable and bio energy resources and the influence on user behaviour. VTT develops energy-efficient building- and district-level solutions for new, refurbishment and retrofit construction. Indoor environment requirements and conditions are user-driven in these solutions. User orientation and new business opportunities are central to the development work. VTT's competence is based on strong technological basic knowledge, solution competence of energy-efficient buildings and technical systems, solution competence of eco-efficient community structures, versatile analysis competence of energy use and total building performance, and on strong international collaboration networks.
The improvement of energy efficiency and implementation of renewable energy resources in buildings are linked with global societal and market-driven pressures. The challenge is to decrease the energy use of the building stock by 50% until the year 2050. Due to increasing environmental consciousness and demand for economical energy, the industry is motivated to develop their product and service portfolio towards total solutions which are advantageous both ecologically and in terms of their life cycle. A human being as user, sensor, client and actor has a key position in the development and in the effective implementation of development results. In order to reduce total environmental load, it is also important develop the energy efficiency of buildings as part of the whole energy infrastructure. In addition to decreasing energy demand, it is essential to reduce the demand for energy production or environmental load due to energy production, respectively.
