The Medical/Commercial building “Glasmaher” is the first low-energy (19kWh/m2a) public building in a small town Brezice / Slovenia. It is situated at the intersection of 5 streets. The form of the building has been dictated by different directions in the urban area. The use of rounded corners is softening its shape, implementing it well into the surroundings. There are retail premises (optics) on the ground floor, medical clinics (ophthalmology, dentistry, etc.) and the business premises on the upper three floors. The design of the building includes measures to prevent energy wastefulness in correlation with minimal investment costs.
