Securing a healthy indoor air climate while saving energy in buildings with space technology
90% exposure to air pollution does occur indoors, causing almost 70% of the total burden of disease related to indoor air quality. With 90% of European citizens spending 90% time indoors, good environment inside buildings is a key public health issue, costing €1,273 B each year. 
Overall, air treatment is responsible for 40% of total building energy consumption, and ventilation-related operations represent alone up to 26% of the electricity expenses. This is because current ventilation approaches consume huge amounts of energy by replacing indoor air with air from polluted outdoor environment. Thus, they need to choose between air quality and energy savings, so the better indoor air quality they achieve, the more energy spending, and the opposite way around. 
SALLY_R is a Swedish cleantech SME that has been awarded twice already for its disrupting innovation, s8AIR, an Air Handling Optimization System that guarantees optimum indoor air quality spending 40% less energy. For an average office building area of 870m, S8AIR‘s energy savings (0.3 kWh/m2/day) would lead to less 63.5 MWh/year energy consumed, amounting for €12,970/year. 
s8AIR combines ventilation approaches used on Earth with the actual technology for climate control in the International Space Station to enhance the performance of air handing units no matter capacity. This is achieved thanks to our own developed smart algorithm that intelligently exploits the real-time data acquired from several sensors. 
Our novel system can be integrated either into existing Air Handing Units in building refurbishment/renovation operations or into new units, so after having demonstrated our product capabilities through the easy deployment in refurbished buildings, we will target AHU manufacturers to integrate S8AIR into their well-known products. With this strategy, we aim to generate €30.2 million accumulated revenues (€10.7 million profit) by 2023, with the creation of 17 direct jobs.
