Bau- und Gartenbetrieb Lahr has its headquarters at Gutleutstraße 23 in Lahr (parcel no. 4290). There are several halls, workshops and social rooms on the premises.

Due to the almost complete sealing of the area, the flat roofs are to be greened and used for renewable energy generation.

In addition, it must be checked in advance whether a new local heating island can be built or connected to an existing heating network. According to the implementation standard of the city of Lahr, the proportion of renewable energies in energy use should be 30% above the legal requirements (EEWärmeG). The use of fossil fuels in newly built heating systems is not desired.

The resulting quarter is to be networked not only in terms of energy source, but also in the field of building technology.

Office and workshop buildings:

The existing building is to be demolished. The new building is to be planned as a roadside building in the sense of a good urban development. In its form, this should clearly form a uniform presence with the already existing personnel and workshop building.

The new building is to move one parking space depth away from the street in order to be able to offer new parking facilities without crossing with the company traffic.

On the ground floor, the elevated warm hall is intended to provide frost resistance (approx. 5° Celsius room temperature) to the four parking spaces for BGL's commercial vehicles overnight. While the large workshop in the adjoining part of the building will be used to repair one's own vehicles by means of lifting platforms, crane runway and additional pit, the small equipment of the construction and garden company can be processed in the adjacent room (approx. 17°Celsius room temperature).

The vertical development of the offices above is to be arranged by elevator at the linchpin of the building yard. The offices are to be arranged on one level on the upper floor with an optimal view of the courtyard. The new administration not only has offices for one to three workstations, but also has a tea kitchen and a training area that can be added to the tea kitchen. In these rooms, optimal air circulation (cold/heat) and sufficient natural lighting and illuminance must be ensured.

In addition to the possible renewable energy sources, the flat roof areas must also be provided for rainwater retention and greening.

Kalthalle:

The new vehicle hall is to be structurally connected to the existing warehouse buildings. The existing covered parking spaces (8pcs.) are also to be merged with the new vehicle hall to form a unit by means of a coherent street layout.

The hall will provide a night-time and dew-free shelter for about another 20 short commercial vehicles (5m) and 10 long commercial vehicles (10m). The safe storage of vehicles directed for the following day should be guaranteed.

The new drive-through solution is intended to ensure safe and easier traffic management and by creating many large parking areas in the dry, the daily attachment and hanging of the trailers is no longer necessary.

Optimal ventilation and plenty of daylight in the cold hall must be ensured. The roof pitch of these roofs must be provided for PV systems. The green flat roof areas are intended to ensure rainwater retention

The aim of this procedure is the award of the necessary specialist planning for technical building equipment (§§ 53 - 56 HOAI) LP 1-9 in stages, initially LP 1-4
