“…In Russia, space heating is responsible for 58% of the overall energy consumption in residential buildings with district heating systems, which cover c.a. 75% of all dwellings [3]. Due to current global climate change and depletion of fossil fuels, the rational use of thermal energy in dwellings has become a hot topic.…”

Due to global climate change and fossil fuel depletion, the rational use of thermal energy has attracted great research interest. Large differences between indoor and outdoor temperatures in cold regions results in huge amounts of heat waste and drop in indoor humidity. Ventireg, an adsorption method, has been often recommended for heat and humidity regeneration in cold countries. In this research work, VentireC, an advanced method employing two thermally coupled adsorbent beds is discussed. It allows the heat released during adsorption of moisture in one adsorber to be transferred to another adsorber to facilitate water desorption. The VentireC approach is comprehensively analysed and described in this paper. A composite adsorbent based on LiCl in silica gel pores, which can exchange up to 0.5 g-H2O/g-sorbent, is selected for VentireC processes under cold Western Siberia conditions. Mathematical simulation of humidity recuperation, employing the selected sorbent with and without thermal coupling, demonstrates the advantages of the VentireC process.

“…Therefore, a further improvement in a dwelling's thermal efficiency might be associated with a decrease in heat loss in ventilation systems [3,4]. The use of heat recovery ventilators (HRVs) in buildings can reduce energy consumption by heating incoming fresh air.…”

“…By the end of 2012, the total floor area of dwellings in Russia reached 3.3 billion m 2 , 72.2 % being related to urban development [17]. In Russia, the space heating is responsible of 58 % of overall energy consumption in residential buildings with district heating systems which cover c.a.…”

“…A small part of dwellings built after 2000 meet acceptable heat efficiency requirements, whereas the majority of older buildings have significantly lower space heating efficiency. The value of Specific Energy Consumption (SEC) for space heating strongly depends on the year of dwelling construction: for buildings [17], which leads to radically lower heat losses through the building constructions (Fig. 2).…”

More than half of the world's population currently lives in cities. An essential constituent of future sustainable cities is energy efficient and ecologically sound buildings which ensure high levels of comfort and convenience without reducing the standards of living. At present, a significant part of primary fossil fuels is spent for heating/cooling of buildings, thus, greatly contributing to total GHG emissions. In this paper, typical heat losses in dwellings are considered taking the United Kingdom and the Russian Federation as examples. The role of adsorption-based technologies for more rational use of heat in buildings is discussed. Fundamentals of inter-seasonal adsorptive heat storage (AHS) are briefly considered. A tentative upper limit of the AHS storage density is estimated. Current practice of inter-seasonal AHS and novel smart adsorbents promising for this emerging technology are overviewed. Since a portion of the heat losses in ventilation system significantly increases in modern buildings, a new approach to regenerating heat and moisture in this system is discussed. Finally, optimization trends of the AHS in buildings are briefly considered.
