Measures aimed at improving energy efficiency often have a positive impact on living comfort as well; in other words, it’s not just about reducing electricity bills or carbon footprints.
When applying for an energy subsidy, improvements to the building’s airtightness must be verified through airtightness tests conducted before and after the renovations. Vertia is one of Finland’s largest, if not the largest, leak test measurements "We have experience with everything from new construction projects to buildings that are a hundred years old," says Jukka Aravirta of Vertia Oy.
More than just an energy certificate
With experience, our measurement process has become precise and efficient, and in addition to performing the work ourselves, we can guide the client in preparing for the measurement to ensure that the greatest possible benefit is derived from it. During the measurement, it is also advisable to locate air leaks under high negative pressure using a thermal camera or smoke tracer. This provides more accurate information on air leaks related to living comfort, the proper functioning of structures, and the building’s energy efficiency, says Jukka Aravirta.
The measurements required for the energy certificate should be taken as early as possible, once the building components that affect airtightness have been installed and other sealing work has been completed. Otherwise, potential leaks may be hidden behind cladding, or there may not be enough time to make repairs. For example, if you want to verify the success of sealing difficult structures as early as possible, quality assurance measurements can be performed during construction prior to the official measurement.
"Quality assurance and survey reports are also valuable documents when it comes to selling a home," Jukka Aravirta sums up.
