The solution for insulating the building, while providing heating, cooling and air renewal in each room.
Concept
This industrialised solution insulates the passive building façade thermically, avoiding condensation risks and offering different aesthetic appeals. The ventilation unit (VMU) is integrated into the façade with pipes and ducts to and connected to the centralized Heath Pump (HP) system for heating and cooling and air renewal. The integrated solution also features windows.
We compare the prefabricated solution with 2 possible scenarios:
OPTION 1: Each room requires a split system for heating and cooling, and a punctual ventilation unit.
OPTION 2: Only one ventilation unit is required for the whole apartment.
Manufacturing
Traditional façade and windows
Single elements are separately produced and sent it to the building site from different factories
Prefabricated integrated façade
Individual elements are fabricated separately and delivered to the prefabricated façade manufacturer. All components, including windows, ducts, and VMU, are assembled in the factory to form a unified module, which is then transported to the site
Waste
Traditional façade and windows
-
Prefabricated integrated façade
Limited due to factory optimization and correctly separated, stored and recycled
Assembly time
