Pellet-Based District Heating and Contracting Model

As implemented in the Bad Camberg project, a centralized district heating system was installed.

Technical concept:

Central pellet heating plant

Heat distribution to all 24 units via district heating network

Domestic hot water supplied through in-house heat exchanger systems

Photovoltaic system powering the energy center

Battery storage supporting partial energy self-sufficiency

The heating plant remains under the ownership of the developer.

Heat supply is structured under a contracting model.

Advantages:

Approximately 30% below market-standard energy prices

Stable long-term pricing

Reduced technical complexity within individual units

Parking Requirements and Site Conditions

Due to local parking regulations, the following were constructed:

18 parking spaces for the 18 apartments

12 parking spaces for the 6 semi-detached houses

The property is located in a third-row position, while infrastructure access was already established.

A significant number of trees were present on the site. The development approach aimed to preserve and integrate as many existing trees as possible within the overall project design.

Economic Overview

The project was fully marketed and completed within the standard timeframe of approximately 12 months from building permit approval. The change order rate remained below 2%.
