passive house

The article examines the effect of thermal insulation from autoclaved aerated concrete on the energy characteristics of a single-family house. Analysis of mathematical models of energy characteristics of external enclosing structures of buildings depending on the thickness of AEROC autoclaved concrete products according to the criteria of heat loss shows that the thermal resistance value of 7.11 m2K/W and the heat transfer coefficient of 0.141 W/(m2K) are achieved using the wall block AEROC D 300 and AEROC Energy thermal insulation panel with a thickness of 200 mm.

There is a great deal of research involved in designing zero-energy buildings and engineering systems for them, however, there is little research to determine the amount of heat absorbed by wind flow from the surface of energy efficient and passive houses. The purpose of this scientific work was to evaluate the effect of wind pressure on the surface of a zero-energy building depending on the direction of flow around the air stream. To that end, it was created hollow building model in scale 1:16.

The article analyzes the problem of carbon dioxide emissions in the construction industry and calculates the energy efficiency of an multicomfort house. The potential for energy savings and CO2 emission reductions remains largely untapped due to the removal of technologies from new construction, the lack of effective environmental policies and insignificant investments in energy efficient buildings.

The implementation of the concept of passive house construction allows you to save conventional fuels.Alternative energy sources are used as energy resources of life-support systems of passive houses. In Ukraine, much attention is paid to using the solar energy for hot water supply and low potential energy of soil for heating.

Every year in Ukraine the demand for passive houses is increased. The passive houses are characterized by specific consumption of thermal energy for heating system up to
