Flat roof buildings
How to create a valuable roof?
The Multifunctional Roof Edge (MRE) is the answer.
What is the MRE?
The Anerdgy Multifunctional Roof Edge (MRE) is the only headache-free, all-in-one product for flat rooftops, combining integrated functions, attractive design options and local renewable energy generation.
The MRE is classified as building technology. It takes over the required functionalities from the roof edge area and provides many options for a integrated design.
Multi-family houses and office buildings with MRE can generate typically more local renewable energy then comparable buildings with classic inner PV roof installations.
What are the benefits?
- Roof design freedom
Possibility for greening, urban farming, roof terracing. - Value space for tenants and owners
The roof becomes a quality living space. - Integrated building functions
Lightning protection, safety rail, rain water handling… - Local energy generation
Renewable solar electricity and solar heat. - Economically viable solution
Saving costs through multifunctionality.
MRE main features
The integrated safety, building and lifestyle functions of the MRE provides you with an all-in-one solution and reduces your project costs and planning time by only requiring one supplier.
Integrated safety functions
Lightning protection
Safety rail
Roof edge and facade protection
Optional building functions
Space for air conditioning / ventilation
Weather station
Rain water storage
Building maintenance unit
Anti-collision lights
Video / surveillance
Further optional functions
Bee / insect housing
Antenna hosting
The individual design options allow you to visually integrate the MRE into your building at the design and planning phase. The positioning of the system at the roof edge frees up space on the rooftop for countless design possibilities.
Design possibilities enabled by MRE
Attica floor level
Urban farming
Terrace
Roof greening
Facade greening connection

Space for other installations
Design Options
Visual integration
Colouring
Illumination
The MRE delivers your building with reliable renewable energy at a high rate of return.
Renewable Energy
- The solar radiation is used in the front and rear MRE surface direction to generate solar power and optional solar heat.
- With an integrated wind turbine,
the natural wind energy is aligned and accelerated at the edge of the facade
via a venturi channel. - It is also possible to design the MRE as an energy roof.
Gas boiler(s) or mini CHP units can be integrated directly under the MRE system for this purpose.

Product Variants
MRE-Light
The MRE-light offers an optimal solution for most flat roof buildings. Solar radiation is used in order to generate a high amount of local renewable energy.
It provides the basis of a multifunctional roof edge system which, if planned correctly, meets the requirements of the necessary roof regulations.
The MRE-light is a great solution for both economical and ecological aspects.
MRE-Hybrid (formerly "WindRail")
The MRE-hybrid offers the unique possibility to use the wind flow on flat roof edges as an additional source of energy.
Highly effective energy generation on the roof edge is achieved by combining PV with wind energy.
Beside wind electricity generation, the wind flow can also improve the efficiency of air conditioning units.
The economics of the MRE-hybrid strongly depend on the use case, the specific conditions of the location & regulatory aspects.
