– Determination of moisture (water and water vapour) transport parameters,
– determination of the indoor climate parameters, from the moisture production and ventilation analysis
of the assessed space,
– evaluation of the homogeneity of the structures based on the non-contact measurement of surface
temperature fields,
– monitoring and analysis of hygrothermal behaviour of buildings in situ or in laboratory,
– investigation of heating systems behaviour in relation to their control,
– Long-term monitoring of hygrothermal behaviour of envelope structures,
analyzing the influence of air convection and moisture transport on heat transfer and
volume changes in them.
– Investigation of daylighting in buildings.
– Daylight climate evaluation.
– Measurements of long-term daylight availability.

Consultancy and diagnostics

– Consultancy and diagnostic activities for investors, designers, contactors, producers, users and
facilities managers, based on testing and numerical analyses of defined hygric, thermal and
durability problems occurring in buildings.
– Daylighting design consultancy, evaluations of daylighting in exterior and interiors as well
as solar energy utilization in buildings
