Buildings that require almost zero energy for cooling and heating is not an option anymore, it is a requirement that defies our future way of life. Since we are certified passive house designers, we at Vivacitas Homes design all our buildings to be following the Passive House Institute standard. This means slightly bigger initial investment in comparison with a traditional way of designing, which will lead to greater comfort and less resources for maintenance.
Designing such a house, can be challenging. Almost every single element in the house is crucial for the passiveness of your home. Designing almost zero energy home depends on the atmospheric conditions surrounding the house, such as orientation, shading, surrounding buildings, terrain condition, prevailing winds, seismic activity etc. Bellow you can see some of the key elements that are required following the Passive House Standard.
This is a must for every building no matter what. The colder the climate where the house is located, the thicker and better the insulation layer should be.
In our buildings we incorporate windows with the best U-values, based on the climate and the budget of the client.
It is needed in order to prevent moisture entering and damaging the external walls. Depending on the climate the airtight layer can be on the inside or the outside of the external wall.
In every house we incorporate HRV (Heat Recovery Ventilation) Units, in order for the house to have a constant flow of fresh air. Alternatively depending on the climate, we can add an additional unit to the system to heat or cool the house.
Reducing the amount of thermal bridges can result in preserving better and for a longer period the stored energy in the building.
Alternatively we can install PV Panels gathering sun’s energy, to reduce the total consumption of electricity of your house through the electrical grid.
