A control unit sends the data to the Vilpe cloud, where it is analyzed. If the system detects exces\u00adsive mois\u00adture in the insu\u00adla\u00adtion layer, two things happen: The building manager is informed via an app and the fan installed on the roof starts auto\u00admat\u00adi\u00adcally and runs at the required speed until the mois\u00adture in the building enve\u00adlope is back within an accept\u00adable range.<\/p>\n<div id=\"attachment_26867\" class=\"wp-caption aligncenter\" style=\"width: 960px\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-26867 size-large\" src=\"https:\/\/mag.ebmpapst.com\/de\/files\/2023\/02\/vilpe-sense_ebm-papst_wasser-dach-entluefung-960x540.jpg\" alt width=\"960\" height=\"540\"><div class=\"wp-caption-border\"><p class=\"wp-caption-text\">Even a small crack in the roofing felt can cause great damage to flat roofs.

This means that damage to rooftops can happen quickly.\u201d<\/p>\n<p>But Vilpe Sense not only detects damage to existing roofs, it also helps dry out new builds: \u201cDuring the construc\u00adtion phase, mois\u00adture is natu\u00adrally intro\u00adduced into the building. Reli\u00adable venti\u00adlation is essen\u00adtial here, other\u00adwise mold will quickly form,\u201d explains Lahti. \u201cIt is diffi\u00adcult to provide good air in living spaces if the building enve\u00adlope isn\u2019t healthy.\u201d This is why Vilpe Sense is avail\u00adable not only for rooftops, but also for crawl\u00adspace venti\u00adlation.<\/p>\n<div class=\"mgznkr-img-slider slides slider-classic size-medium slider-cropped w-660\" id=\"mgznkr-img-slider-_16920_16919\">\n<div class=\"slide-1\"><div class=\" slide-img-crop\"><img loading=\"lazy\" decoding=\"async\" width=\"660\" height=\"371\" src=\"https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-660x371.jpg\" class=\"attachment-medium size-medium  slide-img-crop\" alt srcset=\"https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-660x371.jpg 660w, https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-960x540.jpg 960w, https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-260x146.jpg 260w, https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-1536x864.jpg 1536w, https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-450x253.jpg 450w, https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach-300x169.jpg 300w, https:\/\/mag.ebmpapst.com\/en\/files\/2023\/02\/vilpe-sense_ebm-papst_schimmel_feuchtigkeit-im-dach.jpg 1920w\" sizes=\"auto, (max-width: 660px) 100vw, 660px\"><\/div><p>If mois\u00adture pene\u00adtrates the insu\u00adla\u00adtion layer over a longer period of time, mold quickly forms.

An intel\u00adli\u00adgent algo\u00adrithm controls the speed of the fan installed on the roof. The fan only starts when the sensors in the building enve\u00adlope detect mois\u00adture. But that\u2019s not all: \u201cWhen temper\u00ada\u00adtures outside are cold, the system auto\u00admat\u00adi\u00adcally reduces the speed of the fan because we don\u2019t want to remove heat from the inte\u00adriors,\u201d explains Lahti, adding: \u201cOn the other hand, when the black roofs heat up a lot in the summer and the mois\u00adture evap\u00ado\u00adrates, Vilpe Sense detects this as well and increases the flow rate. Along with the mois\u00adture, it then blows the heat out.\u201d<\/p>\n<p>Tests at the Vilpe lab between May and August 2021 found a total of about 692 kWh of excess heat energy dissi\u00adpated by the system. \u201cThis saves energy that would other\u00adwise be used to cool the inte\u00adriors.

Our prod\u00aducts and their compo\u00adnents have to with\u00adstand this. With ebm-papst fans, we know they are robust enough. We\u2019ve put them through numerous tests and have been using them for many years.\u201d Another plus: They operate very quietly.

In work\u00adshops, I often ask if anyone has ever seen a janitor place a bucket under a leak. Usually, half of the partic\u00adi\u00adpants then put up their hands.
