"step-wise burning process" guarantees a complete "burning out" of the wood with high efficiency rates and low

emissions

Wood is dumped by simply trucks, then automatically dryed, outgassed and then burned

Intelligent control system automatically regulate the firing of wood only in the demanded amount

In case of lowest demand, the system switches to gas/oil firing to remain efficient

Energy Performance Contract

- The contractor designs, constructs, and obtains the necessary financing for an energy supply project

- The building owner / tenant makes payments over time to the contractor in the energy bills

The contractor guarantees the energy supply for heat, cool and/or electricity.

Clean Energy concepts are developed in reconcilement with the building owner and the M&E consultants.

Contractor delivers the clean energy and runs the technologie systems.

─► Any certification benefits - like LEED / Greenmark points - credits to the building owner.

The contractor delivers planning, realization, operating and maintenance of the energy system.

Contracting can be organized in residental and nonresidental buildings, districts and industrial energy

systems.
