May have utility computing building physical processes affect the profitability of the construction of a passive house? The paper presents room warmer results of analysis of the effect of thermal bridges on the example of passive house (EPD) based on porous concrete and the recognition that the consistent treatment of thermal bonds in connection structures can be achieved only Thermal, but also optimize investment property. This paper summarizes the experience of designing a house in energy passive standard in the village Tureň Senec (Fig. 1, 2), completed in 2010.
Consistent assignment of all relevant values in the balance sheet of thermal energy room warmer calculation ensures the exact result of the heat input and specific heat for heating, which is mainly in the case of EPD very important. Neglecting the effect of thermal bridges can mean deviation of energy consumption not only the object down (due to negative values of the loss coefficient of linear thermal bridge Ψ e), but also up (greater heat loss during actual use of the building as calculated).
Simplify the calculation of the energy balance or inaccuracy may already proposed room warmer construction lead designer on the effort to reduce heat loss, for example. irrational over-dimensioning thickness thermal insulation layer circuit elements, associated with unnecessary increase in investment. Overcharge structures may also be present as a result of unnecessarily difficult and complicated solutions detail design nodes, arising from the uncertainty of the designer, if the details after authentication using building physics calculations. In the case of thermal bridges negligence or improper solutions, in addition to increased heat losses as thermal room warmer bonding room warmer may be a minimum internal surface temperature closer to the critical value.
Necessary for verifying the values of the loss coefficient of linear thermal bridge Ψ e were in the case of object-selected typical construction joints, room warmer which could in scope and length affect the heat loss of the object and the overall result of the energy calculation PHPP. It was mainly the installation of the windows details, contact perimeter walls with a roof structure, as well as the floor in place the foundations. 7 evaluated the typical construction room warmer elements, and whereas some details to simulate the variant solutions globally was conducted room warmer 18 simulations. Calculations of thermal bridges have been prepared program for the construction of thermal technology Therm 5.2, allowing calculation of two-dimensional (2D) stationary temperature fields. Simulate the heat flow, linear loss coefficients of thermal bridges Ψ ea minimum surface temperature θ a, min, and thermal transmittance coefficients room warmer of heat transfer and structural elements that are found in Thermal contact with the ground.
When designing EPD is necessary to take into account the specificities of its structural system. This object is made of porous concrete complete system. External walls are constructed of porous concrete blocks P2-400 (hr. 25 cm) of insulation from the gray EPS (hr. 26 cm). Porous concrete ceiling parts (hr. 20 cm) are insulated roof EPS 200S (hr. 38 cm), the concrete slab on the ground floor is 28 cm EPS. Porous concrete material benefits are manifested not only in the printed envelope elements (due to the low thermal conductivity of masonry blocks, room warmer λ = 0.12 W / mK, and ceiling panels, λ = 0.19 W / mK, thickness can be significantly reduced thermal layers) , but also in the contact of components. The results of thermal simulations show that the most important thermal bridges are connected peripheral wall, on the ground floor and base (positive value Ψ e) and attic in place masonry perimeter walls and corners of the peripheral wall (negative values Ψ e). Thermal room warmer bridges in place of window lintels are of negligible value.
Detail in Fig. 3 is a standard solution lintel EPD full overlay window frame insulation. Due to the creation of the cassette blinds is to address the detail of the window recess room warmer in the whole building uniform (Fig. 4), and because room warmer a uniform method of installation of windows, as well as a uniform width of the outer and inner sills. Window frame is embedded into the heat-plane entirely, but at 2/3 of its thickness, but this does not in terms of thermal deterioration of the fundamental values of Ψ e = 0.008 W / mK, the standard solution is Ψ e = 0.002 W / mK
The investor requesting installation of blinds room warmer without visible cartridges, therefore it was necessary for the blinds to create space. This caused a break in continuous thermal insulation
