Berlin Energy Supply Contracting
Topic of the practice
Reduction of energy consumption and energy costs by the modernisation and the optimisation of energy infrastructures, the production of decentralised energy by Combined Heat and Power (CHP) plants and the reduction of related GHG emissions.
Good Practice Information
The Berlin Energy Supply Contracting project targets building owners, real estate companies, public administrations and industry companies by offering them complex solutions for developing, installing, operating and financing energy-efficient supply plants in buildings.The Contractor is responsible for planning, installing and operating of technical facilities for energy supply (e.g. heating, cooling, lighting, compressed air) over a defined contract duration. Typical saving measures include:
* Heat generation: replacement / modernisation of boilers, condensing boiler technology, changes of energy source, e.g. oil to gas, reduction of over-capacity of the heat generation;
* Heat distribution: modernisation of heating equipment (pumps, valves, control units), hydraulic balancing, thermostatic valves;
* Heating optimisation: adaption of heating curve, heating times;
* Hot water generation: replacement, optimisation of storage volumes;
* Optimisation by decentralisation of energy management: control on temperatures, interval timers, legionella control using sensor
The investments are realised without any additional cost to building owners, as all costs are borne by the contractors.
Evidence of success
The project is on-going since 1996. The investments are realised without additional costs to the building owners and the energy service compnay takes the financial risks. All services come from one source. The agreements results in reduction of energy costs for costumers and increased profitability for contractors.
