Monday started at 9am at BOKU with a lecture by Prof. Martin Treberspurg on Sustainable Architecture, Passive House, and the Austria House in Whistler built for the 2010 Winter Olympics.

The topic of asbestos came up and Dominik (from Quebec) mentioned that although asbestos is no longer allowed to be used in Canada, the government keeps the asbestos factories in business by letting them export it to other countries where it is still legal, even though Canada knows it is a cancer-causing product.

Prof. Treberspurg presented several case studies of developments he had worked on. One of them was the multi-residental building Osramgrunde. It features passive solar heat gain, a shape that blocks the too-strong NW wind, and greywater treatment with heat recovery that is recycled to flush toilets. Because of the strong wind mentioned, Max asked why Vienna does not have rooftop wind turbines. The professor and Neda said that based on studies done, the wind speed is not adequate and thus wind turbines would not be economical.

Another case study was Solar City Linz-Pichling, a Linz city expansion project from 1996 to 2005 for 2700 residents. We will be visiting Solar City this weekend. It contains the first passive house in Austria. The development has a non-rectangular city grid system, similar to Tabor, a medieval Czech town.

Then DI Roman Smutny presented a workshop on the IEAA (integrating energy-relevant aspects in architectural competitions) assessment tool.

In the late afternoon we visited Schönbrunn Palace and walked through the opulent rooms with an audioguide. It reminded me of Versailles, but less over-the-top. After the tour, most of the group climbed to the top of the hill to the Gloriette structure, overlooking the palace. It had been a long day but the sun was finally coming out, just in time to take photos.

We also uploaded some pictures on Facebook for you to see!
