Sonnenschiff (lit. 'sun ship') is a large integrated office and retail building in Freiburg im Breisgau, Germany. It was built in 2004 in the city's Vauban quarter as part of the Solar Settlement at Schlierberg. Sonnenschiff was designed by the architect Rolf Disch (who also built the Heliotrope building) and generates four times more energy than it uses.As a whole this building produces more energy than it consumes per year and utilizes the most up-to-date building technology. Some aspects that make this building particular are its vacuum insulated walls, ventilation with 95% heat recovery, triple paned windows and its energy façade. It is the first positive energy office building worldwide. The office spaces are flanked on both the East and West sides entirely with windows, which maximizes natural lighting and employee views while it minimizes the energy used for artificial lighting. Sonnenschiff includes a supermarket, convenience store and bakery-café on the first floor, offices and work spaces on the 2-4 floors and 9 penthouses on its roof. In addition to the office and retail space, there are two conference rooms.

The Arboretum Freiburg-Günterstal (about 100 hectares) is an arboretum maintained by the University of Freiburg. It is located in Günterstal in the Städtischen Forstamt Freiburg at Günterstalstraße 71, Freiburg, Baden-Württemberg, Germany, and open daily without charge. The arboretum dates back to 1896, or earlier, when its first Douglas fir (Pseudotsuga menziesii) plantations were created to investigate their uses in local forestry. These early plantings focused primarily on useful trees from North America and Japan. Large-scale plantings occurred between 1901-1911 when several hundred thousand foreign trees were planted. After World War II, many rare species were added. Today the arboretum is jointly managed by the university's Forstbotanischen Institute and the Freiburg Botanic Garden, and cultivates around 1,300 tree and shrub species from 60 countries and 5 continents, including mature specimens of Abies nordmanniana, Cedrus atlantica, Chamaecyparis lawsoniana, Cryptomeria japonica, Larix leptolepis, Picea orientalis, Pinus austriaca, Pinus banksiana, Pinus strobus, Pinus ponderosa, Pseudotsuga menziesii, and Sequoiadendron, as well as deciduous trees including Juglans nigra, Populus x canadensis, Quercus rubra, and Robinia pseudacacia. Two walking paths, each 2 km in length, provide identifying information.
