Phoenix Solar Headquarters
Guidelines
Phoenix Solar AG, which has always been a pioneer in the solar industry, a trailblazer into the solar age, a company with a commitment for the future of our planet. And its new headquarters must stand for all this and become a powerful symbol of sustainability. The new headquarters consists of two (and later three) elliptical forms - as a prominent and distinctive ensemble of buildings. Hovering over those powerful and compact corpuses, there are light and elegant flying roofs of solar modules: a combination of solid and lightweight, solar and well-grounded.
It lies in the nature of the company, that their headquarters must be nothing less than one of the most ambitious building complexes of the decade in terms of energy efficiency and use of renewable energies. The own photovoltaic products of Phoenix Solar are used in the building design, and they contribute to the positive energy balance of the building, which will produce more energy than it consumes. The sun plays a role not only in sharing an energy surplus with the public grid, but it also brings light into the building, with sunny, communicative work spaces with a lot of natural light.
Architectural and urban planning
In the first phase, two separate buildings will be constructed, which will be connected on ground floor level. For both of them, an atrium as access and communication zone forms the central core. The atrium also brings natural light into the offices at the inside of the buildings. Towards the western side, there are an operations courtyard and a laboratory building. Both main buildings can also be used independently. For this purpose, the western part of the building gets a separate main entrance. In the second phase, the ensemble will be completed by a third elliptical building - either as an extension on the neighbouring property or on the same grounds.
A motorway divides the old Phoenix Solar from the new headquarters, but they are situated on the premises in a way that there is a view connection between the two sites, and also between the headquarters and Sulzemoos Castle. So that new and old keep in touch.
Construction and functions
Wood is a regionally available, recyclable material, a material with an ideal carbon footprint. Wood is stored solar energy and CO2. So the basic design is based on wood: round laminated wood columns support the ceiling, which is made of segmented laminated timber elements. These also function as the formwork and the tension zone for a timber-concrete composite floor construction. Blocks that contain the toilets and elevators are constructed of reinforced concrete and are used for bracing. All office areas are equipped with raised floors, so that all installations are easily accessible and adaptable to changing requirements at any time.
The foyer on the first floor – with a gallery on the second floor and an atrium at the upper levels – creates not only a communication center, but also provides the access to office and assembly rooms as well as to other operational areas. Around the central ellipse of the atrium, the floor plans of both buildings are easily adaptable to changing conditions, with open or closed office zones. The ceiling is designed as a visible radial wood structure, the partition walls within the office areas follow the basic radial layout like sun rays – while remaining completely flexible: „form follows functional flexibility“.
On the roof under the solar panels there is a roof terrace with leisure facilities, including gym, sauna and fitness course.
Accessibility and Transport
The office building is accessed from Ziegelstadel Street. A broad canopy marks the entrance to the main office building. Deliveries go through the eastern maintenance depot. Bicycles and visitor parking are located west of the building near the main entrance. The two-story parking deck for the employees, which can be approached from both Ziegelstrasse and from the western road, will receive a PV roof, too. There are also solar filling stations for electric vehicles. There will be a “solar bridge”, connecting the headquarters with the old site of Phoenix Solar – for walking, for bikes, solar e-bikes and other electric vehicles, as well as for an electric shuttle bus. The use of the solar-electric surplus of the PV installations on the different buildings for powering the traffic is an option that can be worked out in further planning.
Water concept and open spaces
Using a vacuum toilet system, the waste will be collected in a central tank with very low water content. Kitchen and garden waste is collected here, too. In cooperation with a local farmer, all this waste will be fed into a biogas plant that supplies the biogas for an onsite CHP plant. Grey water is treated on site and recycled biologically. The free space can be encompassed by a water circuit, visible for everyone.
The leisure facilities get a near-natural green design, and only little space is sealed. Rainwater is collected in a natural pond. A sun terrace overlooking the pool offers a relaxing outdoor area with cafeteria. A small park invites the staff to a recreational walk and activities such as table tennis, but also to work and to discuss in the open. For this purpose special areas such as the solar-pavilion and an open work area are equipped with wireless network connection.
Building materials
The materials used are recyclable – as much as possible. The primary material is wood from local forests. The use of reinforced concrete is reduced to a minimum. For the insulation, also recyclable building materials such as flax or cellulose are used. The – mostly natural – materials cannot only be recycled, but also create a comfortable, emission-free indoor environment.
Economy
A compact building always has advantages in terms of access, maintenance, and energy costs. The circulation areas are reduced to a minimum. Due to the elliptical shape, the building envelope is in a nearly ideal relation to the volume of the building. And energy costs are turned into net revenues from feeding in solar power electricity into the grid.

Eichstetten Solar Community
A new development area of about 50,000 m2 was planned for the Eichstetten community in Kaiserstuhl, which would be organized in three different sectors: a mixed area with residential and commercial development, individual lots with single and duplex homes, as well as a community parcel for requirements like a new school with sports facilities.
The southern end of the area borders vineyards, which will serve as a green axis to join the newly planned development with the city center. On this axis will also be the central market place. Additionally the single “green fingers” between the planned building sectors serve as ecological integration as well as surface drainage.
The underlying concept of the modular Plusenergiehaus® elements enables a combination of single, duplex and town homes with pitched roof or a double pitched roof, with different sizes and levels and with different uses. In the northern part alternative building types and housing types should also be built – with options for multigenerational and communal living. All the homes are oriented to the sun so that solar energy can be optimally used passively and actively.

Renningen-Malmsheim Community
Rolf Disch Solar Architecture planned an urban extension plan for the city of Renningen-Malmsheim. In the context of an architecture competition, the main challenge was to join two districts together. A residential building area of 3,000 residents should be developed, predominantly consisting of single-family homes, duplexes and town homes. Additionally there should be multistory residential buildings flanking a central street that provides the necessary public and commercial infrastructure.
The housing community is designed according to the highest sustainability criteria. The homes are oriented to the South, in order to guarantee the optimal natural light and they all fulfill the requirements of a PlusEnergy building. In addition to the optimal energy efficiency of the building envelope, active solar energy systems are integrated into the homes, and the minimal residual heating needs will be provided by a gas-CHP generator and a local district heating network.
A mobility concept is also integrated into the planning: the access roads maintain calm traffic, and the highest possible amount of access to the homes will remain auto-free play streets and communication friendly front yards. The connection to both ‘old’ districts is guaranteed not only by automobile but especially by walking and biking paths and of course with connections to the streetcar. This is how traffic reduction will be accomplished; as well in the sense of “space sharing,” the communal use of the required parking spaces will be provided.
The community is emissions-free, however the ecologic concept does not mean surrendering comfort but rather enabling a higher living quality. Special thought was spent on planning the green corridor: an open green space that follows along an existing creek that serves as a city park with significance beyond the just quarter itself. Every property has direct access to public green space, because generous retention spaces were left between the rows of houses. The central boulevard extends itself into a tree-lined neighborhood square and the other important access roads were also designed as avenues flanked by lush vegetation. Despite the urban densification and the cautious and intense allocation of space as a resource, green living property will be offered.
But sustainable building means maintaining flexible space use, and at the same time that the demographic factor is considered. Both will be met with the extended garden parcel on each property. An extra home can be built on this land, which offers enhancements in the sense of multigenerational living, flexible property division or further acquisition of that property if it was not originally purchased by the owner. Likewise the use of this garden parcel can also serve for example as an office or practice, so that living and working can be combined comfortably. That is how a robust high-grade adaptable housing community will work, both with regards to climate change as well as climbing energy prices.

Freiburg EXPO 2010 Entry
The city of Freiburg was invited as the “Green City” to the 2010 Shanghai EXPO. As part of an invitational competition Rolf Disch Solar Architecture submitted a design for the EXPO. Thus we prepared a design with two very different rooms and content-oriented concepts.
An entry in the world exhibition that leaves an impression behind first needs to provide a concept with a global charisma and second needs to create the utmost effective rooms. That is why a Freiburg Charter will be composed first. This will sketch the prospect, open new debates about the sustainable city, here locally and worldwide: a first-rate marketing instrument.
The exhibition stand is therefore reserved alone for the distribution of the charter. It will be a charged atmosphere: the Dome of the Charter. The Freiburg exposition itself will be presented separately as a striking building, which represents the world’s highest sustainability standard: a „Green City Tower“. The „Dome“ and „Tower“ guarantee images, for which Freiburg’s EXPO-presence will receive global press.
The Dome – a magical place
The exhibition booth will be converted to a symbolic room, which will cast a spell over all the visitors to the hall: 8 meter white fiber glass scrolls hang above a golden floor – in the style of Chinese calligraphy. The cupola is effectively illuminated with red and blue LED-lights.
The entrance is marked by two wider red scrolls. The theme of the ‘Freiburg Charter’ appears once again on the back red wall, above the red table in neon writing. At eye-level the charter’s text can be read on the white scrolls in languages from around the world.
The Freiburg charter should show the local and global means to a sustainable city and 100% regenerative energy supply. Visionaries and pragmatics hold the balance, similar to the Athens Charter (1933, 2003) and the Solar Charter (1996).
In the center of the Dome you will find a round table, in the middle of which the Freiburg Charter will be symbolized as a golden book. There are interactive terminals embedded into the table. This is where visitors can become charter participants: they can virtually ‘subscribe,’ which will give the system their name and E-mail address. They then become members of the ‘Charter Community Forum’ with a personal profile, which can later be used from their own PC.
The round table represents the idea of community and cooperation. The visitor has the option to personally become a ‘part of the solution’ in a ‘network against climate change’ and for the sustainable city. The basic nature of the internet-step is interactive with dynamic user-generated content – without large editorial input. This virtual room opens possibilities for the marketing and for links to local institutions and companies. The concept can be further developed beyond the EXPO.
The Freiburg Green City Tower in Shanghai
The Green City Tower gives the 2010 Shanghai EXPO a symbol that leaves an imprint on its visitors: a walkable sculpture. It offers a distinctive image – for the EXPO showcase and for marketing. Its inside is adaptable through the open floorplan as ideal exhibition space.
With an area of 440 m2 a visitor count of about 1.5 million people can be reached. Its outside space can fit about the same amount as well. With the iconic character, the Green City Tower has the potential as the “Messenger of Freiburg” of receiving ever guest to the EXPO.
The Green City Tower shows today’s attainable optimum in energy efficiency. It is rotary mounted, so that throughout the day it can continually align itself to the sun’s position. For exhibition operation its rotational speed will be increased, so that it always offers changing panoramas. On the roof you will find a large photovoltaic “Sun Sail,” which like all the technology mirrors the newest and greatest: the Green City Tower produces more energy than it uses. All the components will be pre-made in Germany. It will only take 20 days to assemble.
Through the winding steps inside the central column the visitors can reach the highest exposition level. This is where the Freiburg Charter will be presented in Chinese and English – an ambitious entrance into the exhibition. The visitors glide through the exhibition in a downward spiral, the entire tower is conceptualized as an open floor plan.
In eleven themed rooms – one theme per quarter circle of the building – Freiburg’s critical accomplishments will be shown with their global translatability in mind. The concept is open for contributions from all the actors of the Green City. Freiburg presents itself first with a reputation-carrying ensemble and with
the Vauban city quarter, which can be further drawn upon in all the themed areas. Finally is the room with visions of the future 2010 planned projects. To minimize subject overkill and at the same time in order to have each of our exhibits maintain the same high aesthetic quality and to exactly regulate our visitor’s flow through the building, the main content will be presented through short films. Like the internet platform, the films can also be further used – and modern media is the most ecological at the same time, because no additional material must be produced.
A partnership was won with the Baden-Württemberg Film Academy in Ludwigsburg, which can implement the ten main themes in ten modern, spirit-full, 90-second clips, which attract attention and stay in the public’s memory. In lieu of the usual flat screen displays, we will adopt a new, semitransparent and most effective special netting.
