The 2014 International Passive House Conference will be held from April 23-27 in Aachen, Germany. Experts from around the world will present practical examples and the latest solutions for energy efficient construction through more than 100 lectures and an accompanying trade fair. Topics will include challenges in different climates, energy retrofits, and pilot projects for special buildings like schools, churches, homes, and offices. The Passive House standard can save up to 90% of the energy used for heating and cooling buildings. Attendees will have the opportunity to participate in courses and workshops or go on excursions to completed Passive House projects in the surrounding area.
