The Department of Building Energetics disposes equipment for the measurement of heat and vapour conductivity, moisture, air and the effect of driving rain on building components. They also have climatic chambers with guarded and calibrated hot plates, mobile equipment for long-term monitoring, IR cameras, computer facilities, demonstration rooms and a hemisphere type artificial sky of six metre diameter, suitable for investigating models up to 0.7m.

The Department is involved in long-term monitoring comparing different heating control systems, typical and solar houses, blocks of flats before and after their energy conscious retrofit, as well as the investigation of comfort in summer conditions in light weight houses.

The artificial sky is able to ensure luminance distribution according to IEC cloudy sky, foggy sky and a clear sky. It facilitates the investigation of the strategy of artificial lighting control as a function of daylight character.

The Department has developed the national standards on building energy requirements, fabric protection and heating load calculation, including the statistical evaluation of the related climatic database and development and distribution of simplified software tools.

Currently energy conscious retrofit and fabric protection is a substantial element of the Department’s work.
