    Standard glass package windows for buildings have several drawbacks: the thermal qualities decreases during the service life. The task of the investigation is to define the necessary constructive parameters to develop window package that consists from several glass layers with the air gap between them, the thermal qualities of that remain during lifetime and the thermal conductivity of the window has to be like the thermal conductivity of another building boundary constructions. In contradistinction to the standard window package, where the gap between the glass layers is filled with special gas, in this case the gap is filled with ordinary air. The expenses of such construction can be less than for windows with the standard gas filled double or triple glass package. Moreover, the thermal conductivity of the standard gas filled package increases during lifetime, because, the gas is escaping out of package and the air is filling the gap instead. For high efficiency buildings, losses through windows are very essential. Such solutions allow to level heat losses on all building boundary surfaces. It is very important for buildings with low or zero energy consumption. Using of such windows will promote rational energy utilization. The thermal conductivity of the multiglass package is experimentally determined in the bench for determination of thermal conductivity and alculations of the heat losses through the package with different parameters are carried out.

    Apartment houses made in the last century in Latvia have rather big heat transfer factor and not good ventilation, especially in cellar. That leads to formation of condensate on building constructions. During cold weather in winter time, this condensate formats ice layer that damages building constructions ant also lead to inconvenience for inhabitants, for example, disturbs opening of cellar door. During investigations the cellar microclimate parameters, such as temperature, humidity and dew point, were measured and different ways to improve them and as result preventing of condensate formation were worked out. The measurements shows that sometimes the air temperature and the temperature on surfaces reaches dew point and therefore the condensate starts to format. The possibilities to eliminate humidity and to increase dew point are worked out during investigations.
