The Trombe wall is oriented on south side of the house, and designed with openings with flaps in concrete core. Those openings are simulated in opened and closed positions. The U-values of the house envelope are considered according to passive house standards. Temperature fields in concrete core...
The Passive House buildings apply super insulation to decrease the heat transfer through the walls, floor and roof remarkably compared with traditional buildings. A large range of thermal insulation materials could be employed to obtain the required low heat transfer coefficients i.e. U-values, which...
Aluminium curtain wall 50 mm wide, insulation by Nomatec XPE (0.039 W/mK). Standard values were used for the stainless steel pressure plate with screws [Delta U = 0.3 W/(m²K)]; and for the non-metallic glass carriers with metal screws [Chi = 0.004 W/K
- Adoption of new details is a barrier for large house builders. - Changing the traditional ‘cavity-wall’. - G value of solar glazing - The common practice values for solar energy transmittance are UK: >50% Building regulations related barriers: - Existing standards. - DHW - Solar thermal...
Let our passive house savings calculator do the rest for you. It will return how long it will take for your investment to be returned. You can also use the further attributes sections to customize values such as: How much energy is supplied from one cubic meter of gas? What is the annua...
To buy a house in the next few years? Saving for your child's education? Financial freedom?Usually, investing money is best for long term goals (5+ years). This gives you time to ride out the normal ups and downs of the stock market.If...
The keys to Passive House builds include higher levels of building insulation, extreme air tightness, no air leakages, elimination of “thermal bridges” (weak spots in the building envelope where heat transfers easily) and building orientation that allows the sun to provide heat in...

First, solar radiation absorbed by the walls, direct and diffused, is calculated using the following equation:(6)Q=UAΔTWhere U is the thermal transmittance (U-value), A is the total surface area and ΔT is the total equivalent temperature difference in which the values are referred to as...
