Even the most die-hard environmentalists can play a guilt-free round of golf at the St. Oswald Golf Club in Austria - and technically, they can also tee off on its roof! Designed by X Architekten, the clubhouse at hole 19 is nestled into the surrounding hilly landscape and topped with a beautiful green roof that extends to the driving range, and the whole complex is maintained without harmful chemicals. The building itself also utilizes impressive technologies to harvest excess thermal energy which is then re-used to keep the bar and restaurant toasty when outdoor temperatures plummet. Unlike the elitist clubs of old that were reserved for snooty high-rankers, St. Oswald is an unusual establishment that welcomes green-minded golfers to an open, environmentally-friendly range.
The clubhouse serves multiple functions. In addition to becoming an extension of the greater greens, it has an inner courtyard where golfers finishing up their game can enjoy a meal or drink, or collect a prize during award events. Both the green roof and golf greens are kept weed-free without harmful pesticides and absolutely no energy is wasted.

The restaurant kitchen produces a lot of hot air which is then filtered through a ventilation system to a hypocaust that heats the floors of the bar and restaurant. A heat exchanger releases half of the heat from the cooler air into the incoming fresh air that heats the clubhouse air and water with the aid of an additional air/water heat pump.
