The ventilation window has a patented thermostatic valve that requires no power connection or complex installation. Negative pressure in the housing unit is maintained by humidistat extractor fans in the kitchen and bathroom. The fans create a constant background air exchange that is boosted automatically in response to activity. The LivingBetter ventilation solution that includes the ventilation windows is calculated to meet the applicable minimum ventilation rate of 0.3 l/m2/h. In similar renovation projects, Danish Technological Institute has shown that, thanks to effective recovery via ventilation windows, it is often not financially viable to take any further measures to recover energy.
Frederikshavn Housing Association expects to launch future projects including LivingBetter’s ventilation window, the development of which was EU-subsidised. A new electronically controlled version of the ventilation window has been chosen for some of these projects. Electronic control allows for the establishment of zonal ventilation and coordination with other energy solutions in the residential unit. Ultimately, the fully optimised indoor climate solution will record and deliver specific data about temperature, humidity, VOC solvent emissions and energy consumption in the housing units.
In addition to housing associations across Denmark, LivingBetter is also the supplier of choice for private homeowners, office property owners, institutions and schools.
