2. Modelling LCC for Different Indoor Climate Systems
Abstract : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial investment costs. A life cycle approach could improve both the economic and environmental performance since the energy use would decrease. READ MORE

4. Strength and colour response of solid wood to heat treatment
Abstract : Heat treatment is a method for improving the durability and dimensional stability of wood. The treatment method used in this work is called Thermo Wood and is industrially applied in Finland. In 2004 production was 31146 m3. The method involves heating wood in a steam atmosphere where the heat causes chemical changes in the structure of the wood. READ MORE
