As part of the global effort to pursue decarbonization, methods for improving the energy efficiency of buildings must be part of the solution catalogue. The XENSIV™ PAS CO2 contributes to 5 WELL features (e.g. ventilation design, air quality monitoring and awareness) and to 6 LEED credits (e.g. optimized energy performance and enhanced indoor air quality strategies). These contributions enable buildings that pursue a certification to earn a maximum of 28 points for LEED and up to 6 points for WELL and has now been confirmed by a strategic assessment conducted by GREENMAP, a program developed by Italy’s leading green building innovation center Habitech.
