Energy Saving at Maintenance of Bulidings with Basementappartments Possessing Vents

Provision of normative parameters of microclimate in basement apartments influences straight the maintenance duration and stability of material properties of protection constructions and temperature regime within ground floor apartments. According to (SNaP, 1995), basement apartments of the buildings should be provided with air exchange multiple equaling kappa=0,5 l/h at the expense of ventilation air holes that does not always find application in practice. Very often vents are open during the whole period of low temperatures. It leads to the fact that the temperature in the basement becomes markedly lower than required according to SNaP 2.08.01-89*. Thermal losses of the ground floor apartments increase in so doing, heat carrier passing through the pipes of basement apartment is cooled markedly that may lead to defreezing engineering communications at sharp temperature drop of outward air in cold periods. At present energy saving of buildings is of particular significance and the problem of temperature-humidity duty of basement apartments is gaining in importance.
