FIRE-SAFE AND AIRTIGHT CABLING OF SOLAR PANELS THROUGH THE ROOF ACCORDING TO BENG REQUIREMENTS
From January 1, 2021, all building permit applications for new construction, both residential and commercial, must comply with the requirements for Nearly Zero-Energy Buildings (BENG).
These new building regulations set requirements for the maximum energy demand, fossil energy use, and renewable energy generation of buildings. This means that for new homes and buildings, not only good insulation of the building envelope and energy-efficient installations must be considered, but also the use of sustainable energy.
Reduced Energy Loss
As a result of the new BENG (Nearly Zero-Energy Buildings) requirements, floors, walls, and roofs must be designed based on a maximum thermal transmittance for BENG 1. (the amount of heat transmitted per second, per m², and per degree of temperature difference between one side and the other side of a roof construction). For the roof, BENG 1 specifies a thermal transmittance of 6.3W/m2.K.
To achieve the maximum thermal transmittance, preventing a linear thermal bridge (cold bridge) is essential. A hole in the construction due to the penetration of cabling needs to be sealed. The correct sealing not only prevents energy loss but also avoids moisture problems and mold formation. The sealing of the passage of solar panel cabling through the roof is therefore crucial. Therefore, the use of airtight cuffs and cable penetrations is important.
A Perfect Seal
For this reason, Conduct has designed an air- and water-tight roof penetration. The PVtube is specially designed to meet the BENG requirements. This means it ensures a perfect seal around the cables, preventing air and water leakage. This improves the energy efficiency of buildings and reduces CO2 emissions.
Integration in Designs
The cable penetration is made of high-quality materials, is durable, reliable, and user-friendly. The PVtube is suitable for flat and pitched roofs and can be easily integrated into your designs. With this high-quality roof penetration, you can be confident that your projects comply with BENG requirements and contribute to a more sustainable future.
Focus on Safety
In conclusion, it is crucial to consider BENG requirements and pay attention to both fire safety and airtightness when designing and installing solar panels through the roof. Engineers, architects, and technical advisors can play a crucial role in integrating these aspects into the design and installation of solar panel systems.
