The Wienerberger e4 house concept was developed with the 2020 building directive by the European Union in mind, aiming towards energy-efficiency and sustainable building, reducing the emission of greenhouse gases by 20% and increasing the amount of utilized renewable energies by 20%.
Wienerberger has developed the e4 concept with experts to offer families an energy-efficient, healthy as well as affordable house. It reflects the growing wish of many private home-builders to make a statement in support of climate protection, while simultaneously realizing their own plans. The e4 concept was already successfully implemented for single-family homes in Austria, Germany, France, Romania, and Hungary and multi-family homes in Belgium and UK.
