Název v původním jazyce

A measurement system for the long-term diagnostics of the thermal and technical properties of wooden houses

Popis výsledku v původním jazyce

To reduce the construction costs and to increase energy savings and the indoor environmental quality in a woodhouse, an energy consumption measuring system for diagnostics of thermal and technical properties of buildings envelope has been developed. At present, the vast majority of calculations for the thermal and technical characteristics of buildings are based on simple mathematical models of building envelope behavior derived primarily from the thermal transmittance of individual materials. However, the thermal transmittance is measured in a stable laboratory environment. Therefore, the measured values may not match the real behavior of materials in continually changing climatic conditions. The Energy Consumption Measuring System has been installed to seven woodhouses in different climatic areas to diagnose the thermal and technical properties of a building's envelope. The power consumption, temperature, and humidity of the air and of the wood, CO2 concentration, temperature of the individual layers of the envelope sandwich structure, and wind speed and direction are measured. Thanks to the sets of real measurements of the thermal and technical behavior, the actual dependence of the indoor environment quality on the outdoor climatic conditions can be obtained. The presented system can reveal imperfections in heat capacity and hygroscopicity of materials used for the construction of a woodhouse. Based on this measurement, the materials can be revised to save the construction costs, energy savings, and to increase the indoor environment quality, together with environmental impact reduction.
