Most previous research in sustainable HCI has focused on electricity consumption in domestic environments or private office spaces. Here, we ad-dress use of lighting in public areas of office buildings with the goal of under-standing and measuring how calm technologies can inspire positive engagement by promoting awareness and competition. We have conducted a 15-month study with the design, deployment, and assessment of two complementary ambient apparatus (one centralized, one distributed) in an office building occupied by ICT start-up companies. Our results show that calm technology can be effective under specific conditions, resulting in a significant reduction of average elec-tricity consumption. We also discovered that in the absence of automatic con-trols, approximately 25% of lighting consumption occurred during off-work hours.
