Quality indoor air improves worker efficiency and, as we saw with the Express Scripts project, improving working conditions saves money and energy while increasing worker productivity. Environmental Health Perspectives (EHP) published a study that examined the impact of quality indoor air on cognitive functions with heavy links back to workforce efficiency.
The participants were placed into controlled spaces that simulated conventional, green, and green+ conditions. EHP utilized nine different cognitive functionalities to test how the participants worked in the three spaces.
• Basic activity level (the ability to make decisions at all times)
• Applied activity level (the ability to make decisions geared towards overall goals)
• Focused activity level (the ability to pay attention to situations at hand)
• Crisis response (the ability to plan and stay prepared/strategize in emergency conditions)
• Information seeking (the ability to gather info as required from different sources)
• Information usage (the ability to use provided and gathered info towards goals)
• Breadth of Approach (the ability to make decisions along multiple dimensions and use a variety of options to obtain goals)
• Strategy (a complex thinking parameter, reflecting the ability to use well-integrated solutions)
The results revealed that, on average, cognitive scores were 61% higher in green spaces and 101% higher in green+ spaces when compared to the conventional space. The benefits beyond energy efficiency should also be taken into account when making your next equipment upgrade.
