Your benefits

Do not pay too much!

We rely on innovative and energy-saving technologies. This effectively reduces heating costs.

Let us do the work in terms of legal requirements!

When you work with Luana, you can be sure that you easily and cost-effectively meet the current requirements of the GEG, EED, and KfW.

Technical support: 24/7. 365 days a year—even on holidays.

We don’t want you to have to deal with chatbots or to be put on hold in the event of a technical problems. Luana employs “real” people who will support you with expertise, commitment, and empathy in the event of a fault. On average, we are able to resolve a problem within 2.2 hours, and we are very proud of this—kudos to our support team!

All data at a glance in real time. Everywhere. Anytime!

Our AI-based monitoring with so-called FEMO® boxes provides you with the infrastructure necessary to collect and evaluate data and process it in regular energy reports. In this way, we enable continuous monitoring and analysis of all relevant processes during ongoing operation, thus contributing not only to a significant reduction in energy costs, but also to reduced CO₂ emissions.

More time for you: We take over your complete operational management!

The safe and efficient operation of your energy plant is not only a question of the right technology and construction, but also of professional support.

In the first step, we create a supply concept based on a thorough analysis of the initial situation and work out an energy supply contract with you.  With the help of our digital remote monitoring system (FEMO®), we take over the technical and operational management during the entire contract period after construction.  With us, you have a single point of contact for energy issues.

Do not give away money and secure all subsidies!

In Germany sustainable building projects are subsidized—for example by the KfW or the Bafa (= Federal Office for Economy and Execution Control). We always have an eye on all funding opportunities and advise you competently so that you do not lose any funding.

Combined heat and power units (CHP)

For a decentralized energy supply

A CHP, a decentralized supporting supply unit for electricity and heat, is an economical and resource-saving way to supply objects with energy. Hydrogen, biomethane (bio natural gas), liquid gas, or natural gas, as well as wood pellets and wood chips are used as fuels. In addition to the generated heat, there is income from the additionally generated electricity (combined heat and power), which is separately remunerated by subsidies. Through this remuneration we subsidize your electricity and heat price, which enables us to ensure a higher price stability than with a conventional supply. Relief of the overall power grid and the targeted utilization of the combined heat and power plant, without the generation of unused heat, strengthen the resource-saving approach. Especially for energy-intensive objects, a CHP-supported energy supply is an optimal possibility for a secure supply.

What is a combined heat and power unit (CHP)?

Energy generation system that produces heat & electricity simultaneously

A combined heat and power unit (CHP) is a system for decentralized energy generation that produces heat and electricity at the same time. In other words, combined heat and power plants are modular systems for generating electrical energy and heat, which are preferably operated at the place where the heat is consumed. Useful heat can also be fed into a local heating network. The system uses the principle of combined heat and power generation. According to the Federal Environment Agency, cogeneration is “the simultaneous conversion of energy into mechanical or electrical energy and usable heat within a thermodynamic process”.

CHP plants are more efficient than “conventional” power plants, as they do not leave the waste heat unused and therefore have a higher overall efficiency. “Conventional” power plants are power plants that are based on proven technologies and fuels that have been used in energy generation for a long time and have comparatively high CO₂ emissions, such as coal-fired power plants, gas-fired power plants, oil-fired power plants or nuclear power plants. According to Buderus, the overall efficiency (electrical and heat) of a CHP unit with a combustion engine can be up to 90 %.

Relieving the overall power grid and the precise utilization of the CHP unit (without the generation of unused heat) strengthen the resource-saving approach. Especially for energy-intensive properties, a CHP-supported energy supply is an optimal option for a secure supply.

How does a combined heat and power unit (CHP) work?

An engine drives a generator that produces electricity, while the waste heat is used for heating

A combined heat and power unit (CHP) works as follows:

  • An internal combustion engine (e.g. gas engine, diesel engine, gas turbine, steam engine or Stirling engine) is operated with a fuel (either fossil such as natural gas, heating oil, etc. or regenerative such as hydrogen, biogas or wood pellets).
  • The engine drives a generator that converts mechanical energy into electricity.
  • The waste heat generated during combustion is not emitted unused, but used for heating:
    • The cooling water from the engine transfers heat to a buffer tank, from where the heating system and hot water preparation are supplied.
    • The hot exhaust gases from the engine are used to generate heat via a heat exchanger.

The electricity generated can either be consumed by the customer or fed into the public grid (usually with remuneration). By combining electricity and heat generation, CHP units achieve very high levels of efficiency and are therefore more energy-efficient and environmentally friendly than conventional power plants.
