Rafytec Oy offers building physics expert services to our clients globally. We promote sustainable buildings and low carbon construction by ensuring the service life and optimal energy performance of the building envelope through rigorous hygrothermal analysis.
Our services include the following:
- Building physical design including numerical hygrothermal analysis of the building thermal envelope
- Analysis of air flows and ventilation inside external walls and roofs
- Analysis of drying performance of walls and roofs
- Analysis of the building physical performance of complex facade systems including thermal and hygric assessments
- Mold growth assessment in structures
- Building physical experimental testing carried out by us and our partners. We design and supervise the experiments.
- Building physics trainings and lectures
- Statements related to building physics
- External reviews of structural design and plans (building physics)
- Moisture management coordination
Mr. Viljanen has a PhD in building physics and holds the highest competence granted in Finland to a building physics expert, FISE PV-qualification. He is specialized in the hygrothermal performance of the building envelope in cold climate.
