Tiivistelmä
The purpose of this thesis work was to determine whether it possible to implement the Passive House technologies in Russian conditions on the example of remodeling of the external wall structure of the existing one-family house.
For this was made a model of one family house, situated in Saint-Petersburg region. In the calculations are used 2 different wall envelopes – wall type I and wall type II (before and after remodeling correspondingly). Wall type I is ordinary brickwork with inside insulation. Wall type II is a constructive, developed by Knauf company according to the Passive House regulations. It add 150mm insulation to the structure, decreasing total U-value. In order to determine the effectiveness of this implementation the investment project was simulated.
Original investment in the investment project is the estimated cost of remodeling. Inflow was the annual energy saving calculated for the 3 types of heating systems (DH, electricity and gas). Energy saving were provided by heat losses difference before and after renovation.
The payback time of the renovation varies from 18-27 years. This result is explained in this thesis work by a number of economic and technical reasons. Also in this thesis work were developed requirements allowing Passive House technologies to be implemented on the Russian construction market.
