The design requirements for sunshade louvers are mainly to prevent direct sunlight from entering the room, as well as to avoid the influence of sunlight scattering and radiation. Secondly, the shape and layout of sunshade louvers should be conducive to the lighting and ventilation requirements of the window, and should not affect the view from the inside to the outside and pursue the coordination and unity of sunshade and architectural design.
The design of building sunshade louvers follows a regular pattern of repetitive changes, presenting a rhythmic beauty with a gradient effect. The rhythmic sense formed by color, material, composition rules, etc., creates a sense of rhythm in the building that is both dynamic and static, especially the adjustable sunshade louvers, which become the most easily perceived objects in the visual environment.

BFFT is located at its headquarters in Germersheim, with impressive floor distribution, flexible layout, and movable sunshade facades. The building was designed by Kandler Bunje and is a modern office and workshop building that can accommodate 500 employees.
This rectangular building extends to the first and fourth floors. The workshop and laboratory are located on the ground floor and first floor. The remaining three floors have office space, including meeting rooms, technical exchange rooms, administrative offices, fitness rooms, and self-service restaurants.

Natural ventilation and lighting ensure optimal working conditions in office and workshop areas. The building has a column beam facade that is level with the room, and glass curtain walls are used on all floors from the first floor to the second floor. Only the first floor on the west side and the parts on the north and south sides are composed of insulated and ventilated facades.
Externally, the multi-layered facade is equipped with movable sunshades and 520 vertical aluminum composite sunshade panels, forming a regular pattern and dynamic internal image of the second layer wall. Corresponding to the smallest room module inside, each room has six Flat noodles, and the corner axe room has seven Flat noodles, which can be controlled by the user independently.

However, these Flat noodles can also be centrally controlled to follow the path of the sun's rays, thus optimally masking the area behind them. They not only prevent glare in the workplace, but also make a positive contribution to the energy consumption of summer office cooling.
The simple and column free indoor room structure allows for flexible division of floor plans, which is clear and uncompromising for both automotive workshops and office structures. All office and workshop areas are covered with floor to ceiling glass, creating optimal working conditions through natural lighting and ventilation.

The fourth floor has also created a gym, yoga studio, and buffet restaurant for employees, which is undoubtedly an attractive benefit for those who work in front of computer screens every day.
The two internal courtyards are seamlessly connected and have ample sunlight, directing the view from the commercial environment to the clearly structured public green space and creating a relaxing place for employees to rest and communicate.

Erich Kestner Elementary School was one of the first buildings built to this passive house standard, and in a two-stage architectural design competition in Leipzig, PBR's design won first prize. The newly built school building consists of two buildings, a three story school and a gymnasium. Two buildings are connected by a one story after-school club building, forming a sleek plastic entity.
The exterior walls of the building are insulated according to the "passive house" standard and covered with bright white aluminum composite material. Adjustable metal composite panels and louvers serve as rotatable sunshades, giving the building a shining appearance, which is its unique feature.

The adjustable vertical sunshade louvers are made of color steel plates and can rotate with the change of sunlight over time, providing shade and sun protection, while also bringing a "rainbow colored coat" to the building.
The second floor can be accessed through an open staircase from the lobby, and a circular skylight allows natural light to enter the lobby. The cafeteria and multipurpose hall face the school playground and are equipped with large windows, creating a multifunctional space that is suitable for both school lunch and activities such as concerts and school gatherings.

The glass curtain wall of the gymnasium opens westward, allowing visitors to enjoy the beautiful scenery of the building from indoors or outdoors. The main advantages of passive architectural style are also highlighted, providing users with a comfortable living, working, and learning environment, as well as energy efficiency and excellent ecological quality.
Good building shading design effectively prevents solar radiation from entering the interior, not only improving the indoor thermal environment, but also greatly reducing the summer air conditioning cooling load of the building. Its reasonable design is an important factor in reducing building energy consumption.
