Abstract. This paper deals with an outcome of long-term experimental measurement of windows suitable for low-energy or zero houses. Three different windows are evaluated since 2011 in the Laboratory of the Department of Building Engineering and Urban Planning, Faculty of Civil Engineering, University of Zilina. All windows have implemented triple glazing, but with various frame type. Two frames are made from plastic and one from wood. The plastic frames differ from each other with use of thermal insulation inside one of mentioned frames. The test room has adjustable indoor boundary conditions and is exposed to real outdoor climate conditions measured through the own detached experimental weather station. Temperatures and heat fluxes are continuously measured on glazings and frames. This paper compares the windows by the requirements of Slovak standard on the inner surface temperatures and differences of the thermal transmittance for glazing and sash.

“…As basis for climate data it serves the measured ones from weather station. The initial conditions for material properties (mass moisture and thermal conductivity) were taken from gravimetric measurement results [12].…”
This article deals with the long-term testing of experimental lightweight wall and comparison of the measurement with two different simulation software packages – WUFI and ESP-r in term of temperatures inside the fragments. Two lightweight timber-frame wall fragments with various outdoor coating colors were exposed to the real outdoor boundary climate conditions for four years. The indoor boundary conditions were secured as constant. In the wall fragments there are several built-in sensors.
“…The thermal conductivity was measured with use of Isomet 2104 and it is described in [10]. The mass moisture values in insulating materials were taken from gravimetric measurement results [11]. Selected material properties used for simulations are described in Tab.…”

The temperature and relative humidity measurement in building physics needs special equipment which is often expensive and not available for young researchers. Several programmable platforms are available. This article describes the low-cost solution of temperature and relative humidity measurement using combined Digital Humidity/Temperature sensors and Raspberry Pi as the datalogger.
Five lightweight timber frame wall fragments with various thermal insulations and outdoor coating colors were exposed to the real outdoor boundary climate conditions. The indoor boundary conditions were secured as constant.
The results of measurement using low cost sensors were compared to values obtained by commercially available thermocouples for scientific use and non-steady HAM simulation in WUFI software.
