Design

Efficiency that looks good

Our building envelope combines maximum efficiency with aesthetic freedom. Thanks to a selection of standard roof colors, the system blends harmoniously into any town or cityscape. The modular elements can be customized to blend architecture, energy generation, and design into a single, cohesive whole.
Overview
Electrical energy
sun

The ultra-thin and flexible solar film is firmly bonded to the top insulating layer and can be easily adapted to unusual shapes. Thanks to the three-dimensional silicone coating, the photovoltaic film can be produced in virtually any color or pattern. This special surface structure with a lens effect eliminates the need for precise alignment with the sun. The dirt-repellent film has a self-cleaning effect thanks to golf ball technology and can be adapted to the specific location (desert dust, seawater, ice, etc.). The homogeneous surface design is achieved by seamlessly stringing the modules together, which can be manufactured in a continuous process. PV technology is evolving rapidly, so the photovoltaic film can be replaced with minimal effort after a few years of use, without having to replace the entire system.
Thermal energy
warmth

Directly beneath the PV film are the guide grooves for the integrated solar thermal system. As sunlight passes through the thin PV film, the initially cool fluid flowing through it heats up and can be stored in the heat pump in the basement and used, for example, for underfloor heating and hot water production. Our combined system offers an exceptional added benefit: When exposed to sunlight, the cool medium cools the PV film, resulting in higher efficiency. This allows the PV film to generate more energy. In winter, a warm medium can be circulated through the system instead of a cool one to heat the PV film and thereby defrost the entire building envelope.
Mechanical energy
wind

Our innovative system enables continuous energy production, even when the sun isn’t shining. By integrating a wind turbine into the roof ridge, we harness wind power to generate mechanical energy, which is then converted into electrical energy. This allows our energy roof to produce energy around the clock. The roof’s pitch and the smooth surface of the photovoltaic film enhance wind lift and optimize energy production. In addition, the turbine is mounted on flexible bearings, which minimizes disruptive noise.

Peripherals and Energy Storage

The innovative system combines three types of energy in one component, eliminating the need for roof truss and sheetrock. Without heavy construction equipment, the construction process is simplified. The insulation material stores particulate matter and CO2, which protects the environment. The system also reduces the use of clay, concrete, aluminum, glass, wood and plaster. The combination of different energy systems significantly promotes sustainable construction.

The comparison shows the material layers of a conventional roof with a PV system and solar thermal panels in direct comparison to our SurPlus Energy System. While a conventional roof structure requires at least 20 layers to be stable, watertight, safe, and durable, as well as to generate thermal and electrical energy, our roof requires only about 6 layers—without compromising stability, watertightness, or safety. This reduction significantly improves the carbon footprint. Thanks to the lower material usage and reduced weight, installation is also simpler, faster, and more cost-effective.

Technical details

Our building envelope makes construction attractive again. Thanks to significant cost savings, attractive funding opportunities, and sophisticated functions, our system completely replaces conventional roof structures and facades. Hover over the following points to learn more.
+ Cost Savings

Our energy roof is self-supporting and therefore does not require an additional roof truss, which saves a considerable cost factor when building a house. Most of the insulation elements consist of a styrofoam-like material that is extremely lightweight. This allows the roof to be erected more quickly and reduces the need for manpower. In addition, with our system, you benefit from various funding options that enable further cost savings. SurPlus Energy is making house construction attractive again.

+ Time and assembly costs

The elements of our roof system are significantly lighter than those of a conventional roof. As a result, they can be assembled more easily and quickly with less personnel costs. There is no need for complex work with heavy wooden beams. Our system is designed in such a way that it can be flexibly adjusted directly on the construction site without heavy tools. Recesses, for example for skylights, can be easily and precisely created on site with a saw.

+ Defrost function

The integrated solar thermal system offers an innovative additional benefit. The smooth surface of the photovoltaic film could lead to increased avalanche formation in winter. This risk is counteracted by passing a warm medium rather than cold through the system in winter. For example, the system can be switched over automatically at a fixed time so that the roof is heated and thus de-iced before avalanches can form. The medium used is then stored and can be reheated during the day.

+ Golf Ball Technology

The photovoltaic film has a specially designed surface structure that is based on a golf ball. This structure offers two major advantages: First, it creates a lens effect that optimally directs sunlight to the surface from various angles and thus increases efficiency. Second, the self-cleaning surface ensures that less dust and dirt stick, allowing the film to withstand extreme conditions such as desert dust, seawater and ice. In addition, the surface in the production process can be adapted for various areas of application.

+ Surety

Carbon fiber threads are integrated into the insulation elements of our roof system, which are firmly connected to the insulation material during the production process. These threads not only ensure the necessary stability of the self-supporting elements, but are also extremely heat-resistant. In an emergency, such as a fire, the insulation material melts due to the heat, but the sturdy carbon fiber struts remain intact. As a result, the overlying PVD film is still supported and the roof remains stable. This prevents the entire building from collapsing.

+ PVD Research

The development of photovoltaic technology is progressing rapidly due to its growing importance. PV elements are continuously becoming more efficient, their efficiency is increasing, and they are becoming ever more robust, lighter and more powerful. Our system is optimally prepared for this. Should it prove useful to upgrade to more modern technology 10 to 20 years after building the house, the new film can simply be applied over the existing one. The time required is minimal and the costs for an upgrade are also significantly lower. In this way, you always stay up to date with the latest technology.

+ Sustainability

Our energy roof is self-supporting and therefore does not require an additional roof truss, which saves a considerable cost factor when building a house. Most of the insulation elements consist of a styrofoam-like material that is extremely lightweight. This allows the roof to be erected more quickly and reduces the need for manpower. In addition, with our system, you benefit from various funding options that enable further cost savings. SurPlus Energy is making house construction attractive again.

+ 24/7 Energy Production

By intelligently combining three different energy sources, our roof can generate energy around the clock. During the day, electrical energy is generated by solar radiation on the photovoltaic film, while the resulting heat is simultaneously converted into thermal energy and stored. When wind blows during the day, our wind turbine generates additional mechanical energy. At night, during storms or renewed wind, the turbine is set in motion again and produces energy again, which is fed into the system and stored.
