Challenged by a client set on doing good work, we studied the opportunity of a row house complex, energy efficient. The enefi® houses were designed starting from the principles of a passive house, for future owners who will enjoy this comfort and who aim to contribute to reducing the carbon footprint.
The thermal envelope of a building is extremely important, as it delimits the climatized interior volume (heated or cooled) from the exterior and from unclimatized spaces. Therefore, the continuity of the thermal envelope ensures a low heat transfer coefficient and, together with other characteristics, leads to an energy-efficient building.
The idea behind this study is the attempt to eliminate as much as possible of the linear thermal bridge that occurs at the intersection of the ground floor with the exterior walls. From the simulations performed, it seems that the solution of taking the floor outside the thermal insulation radically improves the heat transfer through the linear bridge mentioned above.
Positioning the carpentry in continuation of the thermal insulation proves to be a "winning" solution in terms of heat transfer coefficient. The correct installation of a window, regardless of whether it is in line with the masonry or with the thermal insulation, is done with pre-compressed tape (not with foam) and with sealing tape.
Among the advantages of the vegetated terrace compared to the classic terrace, the most important are: thermal inertia (in summer the roof terrace assembly heats up more slowly/less, in winter the roof terrace assembly cools down more slowly/less), protecting the component layers of the system, increasing the surface of the walkable green space of the property.
