Monitoring of Temperatures of a Research Wooden Module House Built in Archangel

摘要

The energy performance of buildings has become increasingly more important. Buildings and structures in the High North are heavily influenced by low temperatures, wind, snow and ice in the winter, and relatively high temperatures and solar radiation in the summer. In the city of Archangel (Russia), temperature difference between winter and summer conditions can be as high as 70°C. For that reason, and under such conditions, it is important to obtain proper temperature distribution in the construction to avoid condensation problems, e.g. reduced thermal resistance and mould growth. Together, the Northern (Arctic) Federal University (NARFU) in Archangel, Narvik University College (NUC) have designed and built a full scale research house on the university campus in Archangel. The house is constructed of modules that were manufactured in Norway and transported to the site in Russia. The house was assembled on site, and was finished in 2007. Since then, measurements of temperature and moisture conditions have been performed. The house is equipped with data acquisition systems for collecting temperature, humidity and moisture content outside, in construction and indoor. This work gives an overview over the measurements, data acquisition subsystems and long-term monitoring results of the experimental house. The facility is fitted with both wireless and wired sensors. The measurement data is available on-line over the internet. Whereas the stationary systems provides continuous readings from a set of chosen sampling points, a mobile system (IR-camera) is used for documenting the actual heat losses from any (local) part of the building envelope. Thermal investigations of the house envelope were performed right after erecting the house and after three years of operation. In this work, in-construction measurements are focused on, analyzed and compared to calculation methods. A possible outcome from this work is contribution to the development of better solutions for insulation, joining methods and assembly of modulized buildings. The established project will be further escalated to include low energy houses suited for cold climate conditions. Further work will be focused towards development of more energy-efficient houses suited for the Northern Europe and the Arctic.
