2 : a conscious choice! turns your roof into an energy source. The is an extremely innovative and sustainable system that allows you and the environment to profit optimally from the energy the sun provides us. With the you will have a smart system that performs its energy-saving work invisibly. And also important: the roof remains watertight as per usual... by

3 The principle The idea is simple. A roof heats up during the day through solar rays and cools down again at night. The ensures that you can harvest this renewable energy in a clever way, store it and re-use it at a later time. can be applied to flat or slightly bowed roofs and is integrated invisibly in the roofing construction. The top layer of the roof exists of dark coloured and therefore highly absorbent roof covering. Below there is a temperature conductive system of pipes that extracts the solar heat from the roof covering. A liquid mixture runs through these pipes and transports this heat to a heat-cold storage system. The heat is stored here until the moment, after a short or long period, it is needed (for example in the evening or during the winter). At the same time the Energy roof can also contribute to cooling a building by having cooled water run through the under floor heating, for example during the night. Nocturnal radiation can allow for heat to be given off via the. The versatile aspects of the The energy harvested on the roof by the can be used in many ways: heating and cooling buildings heating tap water supplying heat and cold for industrial processes pool heating regeneration of imbalances in heat-cold storage systems and combinations of the above-mentioned applications is widely usable and is suitable for many sectors such as house-construction, commercial and industrial building (schools, hospitals, offices), (processing) industry, hotel and catering industry and leisure. Every building is unique The energy demand of an apartment is different to that of a detached house. The users of a school have different demands than the users of a hospital. Every building is unique and is designed for users with specific wishes and needs. The Energy roof is not a stand-alone product but is part of the total installation of the building, such as above- and underground heatcold storage systems, buffer systems and heat pumps. With the help of an optimal tuning between the different components, the can ensure a yield that is completely attuned to the needs of the users. The advantages of the supplies 100% renewable solar energy: saving more than 60 kg CO2/m2 per year reduction of the Energy Performance Coefficient by 0,14 (for a standard reference house) ideal for regenerating imbalanced seasonal thermal storage systems prolonged life span for systems with closed underground storage systems risk of leakage is practically zero; there are no couplings under the roof covering all stainless steel couplings are located under an easily accessible dome construction (Service Unit) optimal energy transfer with the help of a turbulently flowing liquid mixture in the pipe system lightweight, as a result the roof construction does not need to be adjusted invisible and inaudible: only the service points are visible on the roof surface low-maintenance and properly accessible for maintenance and inspection economically cost-effective recovery times, proven long life span and standard delivery with a 10-year guarantee

4 Description of a possible application of the, in combination with underfloor cooling, warm tap water and an aquifer thermal storage system. This is merely an example, the can be applied in numerous variations. Many possible applications have been recorded in our SolarTechnical manual, we are happy to inform you about the possibilities. -Plus Energy from solar heat and sunlight and PV roof covering: an energetic duo -Plus comprises all the qualities of the but adds the many advantages of an amorphous photovoltaic (PV) roof covering. These thin-film PV modules exist of solar cells that generate electrical power. This PV roof covering offers many additional advantages PV cells function optimally at a temperature of 25 to 30 C. Regular flat roofs easily reach a higher temperature on hot days causing the performance of the PV roof covering to be reduced quickly. Because -Plus absorbs and drains the heat of the roof, the roof temperature remains lower. This results in a much higher power yield from the PV cells. diffuse light is sufficient to generate power; therefore very suitable for the Northern European climate it is not necessary to aim the PV cells towards the sun the PV cells are completely integrated in the roof covering and are lightweight, as a result it is not necessary to adjust the roof construction -Plus does not only supply heat and cold but also electricity!
