Moving to Green (01-13-21)

Data collected in Jordan illustrate the complexities of moving into certified-green offices  from other types of structures.  Researchers report that “localised green building codes, especially in the developing world, often do not systematically recognise IEQ or health as crucial issues. . . . we follow 120 employees of a single organisation as they transition from four conventional office buildings to the first green building (GB), designed to the local Jordanian Green Building Guide. . . . Statistically significant differences in thermal conditions, positively biased towards the GB, were observed across the move, and this enhanced occupant thermal comfort. Surprisingly, no significant improvement in occupant perception of air quality, visual and acoustic comfort was detected after moving to the GB, while odour, mental concentration, and glare were perceived to be poor in the GB. . . . our results support the growing concern that green buildings may create unintended consequences in terms of occupant comfort and health in the pursuit of a better thermal environment and energy efficiency.”
