Sun Ship (building)

The Sun Ship is a large integrated office / retail building designed by Rolf Disch and located in Freiburg directly next to the Solar Settlement by the same designer. It uses 60,000 sq. ft. for retail, commercial and residential space.

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 special are its vacuuminsulated walls, ventilation with 95% heat recovery, triple glazed windows and its energy facade .

It is the first positive energy office building worldwide. citation needed ] The office spaces are flanked on both sides of the East and West, and it is possible to use them for the most part.

The Sun Ship guests a supermarket, convenience store and bakery-cafe 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.


MoreEnergy is a term coined by Rolf Disch which indicates a structure of extreme energy efficiency so that it holds a positive energy balance, actually producing more energy than it uses. With the completion of his private residence, the Heliotrope , in 1994, Disch had created the first PlusEnergy house. His next goal in its development was thus the mass application of the concept to residential, commercial and retail space. As the concept is further developed and gained by other companies, PlusEnergy certifications. “MoreEnergy is a fundamental environmental imperative,” Disch claims. [1] Disch believes that passive building is not enough because of passive homes still emit CO 2into the atmosphere .

Community planning

Believing community planning, sustainable development, Disch dedicates. A solar community of general identification and an enormous public image. Disch says he attracts great tenants, creative entrepreneurs and creative work places through his design. Disch always aims to create a community with combined uses for an urban planning concept like a traffic management concept – with wide, attractive walkways, bike routes and connections to public transportation. At the Solar Settlement for example, tenants and owners embrace a bike and carsharing and the neighborhood has an extensive car-free zone with many public transportation connections. Also has community solutions for energy. For example,
