With powerful fans in door panels – so-called Blower Doors – Olle Syr\u00e9n of AEM Byggkonsult checks the airtightness of residential and commercial buildings. Firstly, to confirm developers’ energy calculations and secondly, to detect any air leakage.– “We see a continued increase in demand for density measurements,” says Olle.<\/p>\n\n\n\n

Energy-efficient buildings have long been on the agenda. That is, houses that, thanks to smart design, require minimal energy and therefore have low running costs. Airtightness is an important parameter to consider in order to avoid unnecessary energy consumption. When it is cold and windy outside, a building with poor airtightness lets in large amounts of extra air that needs to be heated. Air leakage and internal overpressure also increase the risk of moisture damage to the building envelope.<\/p>\n\n\n\n

This is where Olle Syr\u00e9n comes in. Olle previously worked as a carpenter, supervisor and project manager on construction sites before he was attracted to AEM Byggkonsult to do construction inspections and density measurements.<\/p>\n\n\n\n

– Density measurements started as a ‘fun thing’. We saw a clear need for such measurements. Not least for housing companies that needed to carry out density measurements to verify their own energy calculations in connection with new buildings,” says Olle.<\/p>\n\n\n\n

Measures of house tightness<\/strong>In addition to confirming the energy declarations, these measurements also show that new constructions comply with the Planning and Building Act and are in line with the building law. This, in turn, means that the building authority can issue a final decision, after which buildings are considered completed and can be put into use.<\/p>\n\n\n\n
