Workplaces are transforming from office rooms to office landscapes. Previous research about indoor environmental (IE) aspects and health, investigated work-related health issues mostly in conventional office spaces. It is still uncertain which physical aspects in office landscapes might influence employees’ health the most. An exploratory study, in a mix method design, including IE measurements and user perception about the indoor environmental quality (IEQ) of the office landscape is performed. Objective IE data showed a discrepancy with how office users experienced the IEQ; therefore, both the Dutch Building Code and user perception need to be considered. ; Workplaces are transforming from office rooms to office landscapes.
