Abstract
The Energy Performance of Buildings Directive (EPBD) per the 2010 directive of the European Parliament requires all new public buildings to become near-zero energy buildings by 2019 and will be extended to all new buildings by 2021. A passive house is something more than just an energy-saving house. This concept involves sustainable, high-quality, valuable, healthy and durable construction. Foundation is one of the most essential elements of a house. The type of foundation for a private house is selected considering many factors. The article examines technological and structural solutions for passive buildings foundation. The technical-economic comparison of the main structures of a passive house revealed that it is cheaper to install an adequately designed concrete slab foundation than to build strip or pile foundation and the floor separately. The comparison of the main envelope elements efficiency by multiple-criteria evaluation methods showed that it is economically feasible to install concrete slab on ground foundation.
