The challenges in terms of climate protection and energy supply security are diverse. The building sector is responsible for around 35-40% of carbon emissions! The savings potential is enormous and climate neutrality in the building sector is absolutely necessary. The passive house standard can make an important contribution to this, because the most sustainable energy is the energy that doesn't have to be generated in the first place. “Energy efficiency is the first renewable energy!” With the passive house concept, energy consumption can be reduced by up to 90% compared to existing buildings; compared to national requirements, the passive house is 3-5 times more efficient! 

As an independent building concept based on physical principles, it can be used globally, offers the highest level of comfort, the best comfort and represents the economic and ecological optimum. Quality is the key to success, both in planning and in execution, but also with the components and people. 

The connection between efficiency and renewable energies will determine the future of the building sector and the passive house has been showing how this can work for over 30 years. New construction and renovation, residential and non-residential buildings, Arctic and tropics, winter and summer, solid construction and lightweight construction – everything is possible. The passive house is a scientifically validated holistic building concept, tried and tested in practice worldwide, robust, low-tech, healthy, comfortable, cost-effective, climate-neutral and fit for the future.

In this lecture, an overview of the concept will be given, tools will be presented and implemented examples will be shown.
