dgj197 Garden Gate: Gateway to the Gardens of the World, , 2013


Design Concept

In the context of diverse and independent gardens and garden architecture of the "Gardens of the World" shows the entrance building a clear and simple gesture: It makes a great entrance. Visitors are guided through the "Garden Gate" on the grounds. The gateway provides insight and creates visual relationships between the site and the surrounding area.

The geometry of the frame is accented by a subtle transformation: The roof has issued the way to the entrance with cash and through the park, the ground shifted towards the park creates a protected area for the visitors terrace. The entrance is easy to find and address educational.

The terrace forms a smooth transition between building and landscape. The side wall of the terrace area creates a privacy screen to the logistics area and the parking lot so that the space and the views focus on the gardens and the countryside.

The clear geometry and the idea of ​​flowing space are continued inside the building. Boxes placed zoning the space without interrupting the overall impression of the gate. They contain the service rooms.

Energy concept and sustainability

The objective of the energy concept is possible with simple structural measures to achieve the maximum comfort for employees and visitors at low cost.

About massive passive measures initially, the energy requirement was minimized:

- Simple, compact building shape with good A / V ratio

- Well-insulated building envelope

- High level of air tightness

- Reduction of ventilation losses through ventilation system with heat recovery

- Use of solar gains

- Minimizing the heated area in winter, depending on usage requirements

- Intermediate areas as buffer zone (covered outdoor area and vestibules)

- Creation of storage mass by massive installations

- Use of sustainable materials

- Flexible use through good Umbaubarkeit interior boxes

- Sustainable use by accessibility

- Low maintenance materials (natural weathering of wood, good accessibility of the discs for cleaning and replacement if necessary)

Plus Energy Standard

To achieve the positive energy standard, the small remaining primary energy demand of approximately 115,000 kWh / year (primary energy demand heating kWh / 37'905 kWh / year lighting and power requirements, use estimated 75,000) is the annual mean be covered by an integrated in the roof of the building PV system: the planned PV system (System Power: 105.98 kWp) on the roof of the building can meet the annual electricity needs of the building and creates Average annual earnings 88 432 kWh, which is a quantity of primary energy of 229 '923 kWh equivalent.

The building is a plus-energy buildings as defined by the BMVBS / BBSR. The PV modules are elevated at a relatively shallow angle of 10 degrees, so that the natural shading of the modules to each other is reduced. It can be placed on the same roof surface more modules. Another advantage of this setup is that the system bessen integrated into building design. The loss of efficiency of the individual module due to the lower mounting angle is small in comparison. The efficiency of this system must be tested in further and compared with the budget requirements of Organised by. It is also conceivable that plant built by an external operator and to be operated, the roof area is available for rent.
