Contracting

The requirement for the use of new energy-efficient technology wins in municipalities and companies considering it outdated energy centers on the one hand and economic, environmental or political necessity on the other hand more and more important. However, lack of investment resources often prevent the use of innovative technologies savings.


When contracting is transferred to modern energy services, in which tasks or the provision of energy optimization of buildings over a contractually specified period to an external service provider.


Completion of Initial consultation contracting:

  • Request / Contact Form
  • Query the current actual situation by questionnaire
  • appointment
  • Initial consultation on site (note the actual situation, definition of project objectives, inspection)
  • Consultation report with proposals for action
  • project-related on demand "stand-by advice"
  • PR work


Contracting options

Since becoming aware of the concept of contracting there was and is always confusion because of the variety of terms used . Clarity - at least for experts - has 8930 Part 5 " contracting" brought the first published since the end of 2003 DIN . The standard defines four different contracting options in their pure forms . Of course, combinations are possible.
More recently, developments (eg performance contracting construction plus renovation) and new approaches can model (eg Sustainable Success contracting naerco ) are observed in the market.


Energy supply contracting

Energy Supply Contracting - often called plant contracting - is the most common variant in the market . Application focus is the renewal or initial installation of equipment in the field of energy centers . The contractor takes over - depending on the desired scope of services - planning, financing , construction, operation and maintenance, and also the most fuel purchase . Standard contract terms include 10 to 15 years.
As a finished product , the contractor will deliver the required final useful energy in the form of heat, steam , cold, electricity , compressed air or light in a defined quantity and quality.
The salary is based on a mostly two-part pricing system consisting of:
  • base Price
  • labor price
The subject agreed fixed price escalation clauses in order to pass on changes in fuel prices and labor and material costs to customers. Energy supply contracting is suitable for existing and new buildings .


Financial contracting

The far less common financing Contracting - also called Plant Leasing - leaves in contrast to other models Contracing the operating system to contracting taker. The service package includes mainly services the planning, financing and construction of mostly well definable investment techniques , such as Lighting and heat recovery systems . The amount of fixed charges usually depends on the contractor - as in the lease - the duration of the contract and the amount of investment from .


Technical Asset Management

The Technical Plant Management - also known as operating management contracting familiar - on an optimized operation of existing or new energy installations the focus of the service. While at market maintenance and service contracts, the operating system remains the responsibility of the customer, assumes in this model , the contractor and the management. The shape of the power compensation to the Contractor customarily similar to the compensation model of energy supply contracting , but with significantly lower base prices .

Contract periods can be very short , but also long-term with one to two years. Not infrequently an agreement on Technical Asset Management in need of a larger facility modernization in an energy supply contracting goes .


Energy Performance Contracting

When Energy Performance Contracting - also known as performance contracting or energy performance contracting - sold the Contractor in contrast to the energy supply contracting not efficiently produced useful energy, but an energy -saving concept with mandatory savings guarantee the required final energies such as electricity, gas , fuel oil , district heating or water and wastewater.
Often there will be a cross-discipline optimization of the existing building in this variant . Guiding principle is guaranteed by the contractor, reduce energy costs , sufficient to refinance forehand end and pre-financed by the Contractor optimization and modernization investments over the HIDE runtime.

Standard contract terms for this model are 6-15 years . Energy Performance Contracting is suitable for larger individual buildings or building complexes with more than 150,000 € energy costs per year . But also smaller buildings (eg schools, administrative buildings ), access to this model is not closed by a bundling with larger objects to building a pool.
In rented buildings with many users performance contracting is not readily feasible .
The remuneration of the contractor is usually done based on performance-based or proven or at least mathematically determinable energy savings. Typical charging scheme :
  • contracting rate

Calculation of achieved energy savings valued at reference prices and reference energy consumption (so-called "energy cost baseline") before implementing the contracting measures


Guarantees savings of 20-25 % of current energy costs can be considered as average. If the savings rate is not achieved at the end of the year , the small amount goes to financial expense of the contractor . If the savings target is exceeded, the customer and contractor share the additional income generally agreed on by distribution keys .

Energy Performance Contracting plus structural reorganization

Current development of the savings performance contracting . In addition to the building will be " energy performance contracting plus" while also measures in structural thermal protection included in the Saving Guarantee Contract .
The amortization periods of structural measures , such as building insulation , are usually longer than the usual contractual terms of energy performance contracting . However, looking at the life of a building , even those measures are often economically .

In order to achieve an overall optimization of all structural, technical and organizational possibilities in the context of a holistic savings Contracing project to offer options such as paying
a one-time construction cost subsidy by the building owner
an additional fixed basic price
or
an extension of the contract period
on unless Contractor and Customer agree to this, and long-term use of the building is in sight.

The savings guarantee of the contractor then applies to the entire package . He takes over the responsibility for the implementation and maintenance of all measures .

Combination models

Basically combinations of different contracting options are possible and - albeit still rarely - reflective of practice. Reasons for the spread of previously unavailable combination models are certainly the lack of publicly available sample contracts and tender specifications as well as the interests of the contracting firms dar.

 

Tend to offer " supply -oriented " rather Contractors Energy Supply Contracting and Technical Asset Management , "technology -oriented " Contractors also quite savings and financing contracting solutions .


More recently, especially with leading providers of energy supply contracting is a development of its services towards a binding efficiency or consumption Warranty observed , eg , etc. by energy supply contracting with guaranteed maximum consumption (energy budget - contracting)


Sustainable success of contracting

As a result of a BMWi Forschungsprojeks " naerco " a whole new contracting model was developed with the "sustainable success Contracting" . Since 2011, it is at the high school market Oberndorf ( Bavaria ) first tested in a pilot application .

Guiding principle of sustainable success contracting : In contrast to Energlieliefer contracting, is supplied with the efficient generated useful energy from new plants , or for performance contracting , in which a mandatory savings guarantee is by an on developing energy -saving concept in focus, it is the sustainable success of contracting a by the contractor is to be guaranteed compliance with pre-defined comfort and quality criteria in the areas in terms of temperature , humidity or power characteristics , responsible for the achievement of the Contractor to be implemented with a technology concept through him .

The contracting rate is for example charged as a management fee in € / a . Deviations from the target criteria must be improved and lead to a reduction in payment .

What are the advantages of contracting ?

  • You will receive an all -inclusive package and not have to worry about anything
  • You get a modern, efficient facility that is economically and ecologically to date
  • You will receive a guaranteed reliable supply of heat for heating and hot water
  • You get a complete service : all services from a single source , ie ,
  • You have only one contact , which governs everything for you : the development of the old facility , the installation of the new system , service, maintenance , repairs, chimney sweep ( - cost ), etc.
  • Save yourself time and trouble : for any repairs or the like . You must neither seek nor offer different coordinate different craftsmen
  • Ensure they remain free, because of the risk management rests with the Contractor . It ensures long-term reliability
  • You do not need special knowledge : because contractors are specialists with the expertise to find the right solution for you and your property
With the completion of a contracting agreement, you bind yourself to the long-term contracting firms, and thus its price conditions. This is not a disadvantage ! Because with a transparent price formation can benefit from long-term planning.
